All nodes

Node	Category	What it does
Action.Ghost	Workflow.Actions	Per item: applies a TEMPORARY transparency to the given items (wire the whole found set) so the highlighted item reads against a faded context.
Action.Highlight	Workflow.Actions	Per item: applies a TEMPORARY color to the current item so it stands out — captured per viewpoint by Action.SaveViewpoint, so each view keeps its own highlight.
Action.Isolate	Workflow.Actions	Per item: shows the current item and hides everything else (Appearance.Isolate).
Action.OverrideColor	Workflow.Actions	Per item: overrides the current item's color (Appearance.OverrideColor).
Action.ResetAppearance	Workflow.Actions	Per item: removes color and transparency overrides from the current item (Appearance.Reset).
Action.ResetTemporaryAppearance	Workflow.Actions	Per item: clears all TEMPORARY color/transparency overrides (Appearance.ResetTemporary) — put first in the sequence so the previous item's highlight/ghost doesn't linger into this view.
Action.SaveViewpoint	Workflow.Actions	Per item: saves the current view as a saved viewpoint named from the item.
Action.ShowAll	Workflow.Actions	Per item: un-hides every item in the model (Appearance.ShowAll) — a reset step, e.g.
Action.ZoomTo	Workflow.Actions	Per item: frames the current item in the view (Camera.ZoomToItems).
Add	Math	Adds two numbers.
And	Logic	Returns true only when both inputs are true.
Appearance.ColorByValues	Navisworks.Appearance	One-node color-coding: pairs each item with its value, colors each distinct value (categorical palette, or a blue→red gradient when every value is numeric) and outputs the legend.
Appearance.ColorByValuesTemporary	Navisworks.Appearance	Like Appearance.ColorByValues, but the colours are TEMPORARY (viewpoint-scoped) overrides: nothing is written into the file, Viewpoint.Save with bakeOverrides on keeps them in a saved viewpoint (colour by clash status or by level, one view each), and Appearance.ResetTemporary clears them.
Appearance.Focus	Navisworks.Appearance	Focus on some items: they stay as they are and everything else in the model fades by otherTransparency percent (0 = opaque, 100 = invisible) with a TEMPORARY transparency override — the Action.Ghost look in one node, no permanent change.
Appearance.Hide	Navisworks.Appearance	Hides model items in the viewport.
Appearance.Isolate	Navisworks.Appearance	Shows only these items and hides everything else (undo with Appearance.ShowAll).
Appearance.OverrideColor	Navisworks.Appearance	Overrides the color of model items (a permanent override: saved with the file and undoable).
Appearance.OverrideColorTemporary	Navisworks.Appearance	Applies a TEMPORARY (viewpoint-scoped) color override — unlike Appearance.OverrideColor (a single global permanent override), a temporary override is what Viewpoint.SaveWithOverrides bakes into each saved view, so every viewpoint keeps its own coloring.
Appearance.OverrideTransparency	Navisworks.Appearance	Overrides the transparency of model items, from 0 (opaque) to 1 (invisible).
Appearance.OverrideTransparencyTemporary	Navisworks.Appearance	Applies a TEMPORARY (viewpoint-scoped) transparency override (from 0 = opaque to 1 = invisible; Appearance.Focus takes percent, 0 to 100) — the ghosting that Viewpoint.SaveWithOverrides bakes into each saved view.
Appearance.Reset	Navisworks.Appearance	Removes permanent color and transparency overrides from model items, restoring their original materials.
Appearance.ResetAll	Navisworks.Appearance	Removes every permanent color/transparency override in the model — a clean slate before re-coloring.
Appearance.ResetTemporary	Navisworks.Appearance	Clears every TEMPORARY color/transparency override in the model — a clean slate before highlighting the next item.
Appearance.Show	Navisworks.Appearance	Shows (un-hides) model items in the viewport.
Appearance.ShowAll	Navisworks.Appearance	Shows (un-hides) every item in the model — undoes Appearance.Hide and Appearance.Isolate.
Application.Version	Navisworks.Document	The running Navisworks product name and API version (report headers, compatibility checks).
Audit.DuplicateItems	Navisworks.Analysis	Finds duplicated geometry (double-exported elements) by running a temporary Duplicate clash test over the items.
Audit.MissingProperty	Navisworks.Analysis	Finds every item that does NOT carry the given property — the data-completeness audit.
BCF.ExportIssues	Navisworks.Export	Exports clash results (or saved viewpoints) as BCF 2.1 issues (.bcfzip: markup, camera viewpoint, component GUIDs, snapshot) — the vendor-neutral bridge into BIMcollab / Konekt / Revizto / ACC.
BCF.ImportIssues	Navisworks.Export	Reads a BCF 2.0/2.1 package: per topic title/status/description/comments/component GUIDs/camera, plus the model items each topic's components resolve to (matched by IFC GlobalId, then InstanceGuid).
Boolean	Input	A true/false toggle.
BoundingBox.ByCorners	Geometry	Creates an axis-aligned bounding box spanning two opposite corner points, given in any order (the smaller coordinates become the box's min corner, the larger its max corner).
BoundingBox.Center	Geometry	Returns the center point of a bounding box.
BoundingBox.Contains	Geometry	Tests whether a point lies inside a bounding box (points on the boundary count as inside).
BoundingBox.ContainsBox	Geometry	True when the inner box fits entirely inside the outer box (touching faces count as inside).
BoundingBox.Corners	Geometry	The 8 corner points of a bounding box: the bottom face counter-clockwise from the Min corner (0-3), then the top face in the same order (4-7).
BoundingBox.Expand	Geometry	Grows a bounding box by an amount on every side (negative shrinks it; shrinking past zero size is an error) — a clearance or tolerance zone around an element.
BoundingBox.Footprint	Geometry	The plan (floor) area of a bounding box: size X times size Y, ignoring height.
BoundingBox.Intersects	Geometry	Tests whether two bounding boxes overlap (touching counts as intersecting).
BoundingBox.Overlap	Geometry	The bounding box shared by two overlapping boxes; an error when they do not meet, so test with BoundingBox.Intersects first.
BoundingBox.PlanGap	Geometry	The widest strip of open floor between an inner box (equipment) and the outer box (opening) in plan — the 'space between the equipment and the opening edge'.
BoundingBox.Scale	Geometry	Scales a bounding box about its center by a factor (2 = double, 0.5 = half) — e.g.
BoundingBox.Size	Geometry	Returns a bounding box's size along each axis and its min/max corner points.
BoundingBox.SurfaceArea	Geometry	The total area of a bounding box's six faces (square model units) — e.g.
BoundingBox.Translate	Geometry	Moves a bounding box by an offset vector, keeping its size.
BoundingBox.Union	Geometry	ONE bounding box fitting every box and/or point wired in — the geometric union, e.g.
BoundingBox.Volume	Geometry	The volume of a bounding box (cubic model units); a flat box has volume 0.
Camera.Current	Navisworks.Camera	The current camera position, focal distance and vertical field height, read again on every run.
Camera.LookAt	Navisworks.Camera	Moves the camera to 'eye' looking at 'target' (up stays +Z).
Camera.Restore	Navisworks.Camera	Puts a camera back on the current view: the viewpoint kept by Camera.Save, or a saved viewpoint.
Camera.Save	Navisworks.Camera	Keeps a copy of the current camera inside the graph (nothing is added to the Saved Viewpoints window; for that use Viewpoint.Save).
Camera.SetFieldOfView	Navisworks.Camera	Sets the camera's vertical field of view in degrees (perspective camera) — smaller = more zoomed/telephoto, larger = wider.
Camera.SetProjection	Navisworks.Camera	Switches the camera between perspective (true) and orthographic (false) projection.
Camera.SetStandardView	Navisworks.Camera	Sets the camera to a standard view (top, bottom, front, back, left, right, iso) and frames the given items — or the whole model when none are wired.
Camera.ZoomToItems	Navisworks.Camera	Frames the given items in the current view (per-item close-ups, screenshot staging).
Captured Selection	Navisworks.Selection	Snapshots the current Navisworks selection and keeps it, so the graph runs on that fixed set even after you select something else (Selection.Current, in contrast, reads the live selection again on every run).
Choice	Input	A pick-list with your own options (one per line); gives the chosen text and its position.
Clash.AllGroups	Navisworks.Clash.Group	Every result group of every clash test in the document, as ONE flat list — the whole-project entry point for group workflows: wire it into Loop.Item and let ClashGroup.Info hand each iteration its results, group name and test name.
Clash.CompareSnapshots	Navisworks.Clash.Report	Diffs two clash snapshots: clashes NEW since the baseline, clashes RESOLVED (disappeared), and clashes PERSISTING in both (with their previous status) — the weekly delta report no plugin does via live API.
Clash.Deduplicate	Navisworks.Clash.Filter	Keeps ONE clash per unique item pair — the same two elements clashing at five points, or mirrored across an A-vs-B and B-vs-A test matrix, count once.
Clash.FilterByAngle	Navisworks.Clash.Filter	Keeps only the clash results whose crossing angle (see ClashResult.Angle) is within a degree range — e.g.
Clash.FilterByDepth	Navisworks.Clash.Filter	Keeps clashes whose penetration depth falls in a range, in the unit you name — minDepth 0.025 with units Meters drops every grazing clash shallower than 25 mm, the #1 noise reducer.
Clash.FilterByItemProperty	Navisworks.Clash.Filter	Keeps clashes whose two items' PROPERTY values match a pair of texts, in either order — the semantic clash rule: category "Element", property "Category", value1 "Pipe", value2 "Wall" keeps pipe-vs-wall clashes whichever side the pipe landed on.
Clash.FilterByOrientation	Navisworks.Clash.Filter	Keeps only the clashes between elements of the given box shapes, matched in either order — shape1=run + shape2=wall keeps pipes through walls, run/riser + slab keeps pipes through floors; Clash.FilterByAngle alone cannot tell those apart (both cross at ~90°).
Clash.FilterBySet	Navisworks.Clash.Filter	Keeps clashes whose items belong to a selection/search set (either one, both, or a specific side) — sets are the coordination scope language: "only my package", "only against the existing building".
Clash.FilterBySnapshot	Navisworks.Clash.Filter	Turns "what is new since last week" into live clash results you can select, group, assign or report: compares the results with a snapshot saved by Clash.SnapshotToFile, using the same identity as Clash.CompareSnapshots (the test and the pair of items, by InstanceGuid or tree path), and keeps the new ones (not in the snapshot) or the persisting ones (already in it).
Clash.FilterByStatus	Navisworks.Clash.Filter	Keeps only the clash results with the given status(es) — pick one from the dropdown, or wire several comma-separated ("New,Active"; the Clash.Statuses node builds that from toggles).
Clash.GroupResults	Navisworks.Clash.Group	Puts an explicit list of clash results into a named group in Clash Detective — YOUR grouping rule, not a built-in one: filter results any way you like, then group what came out.
Clash.GroupResultsByGridIntersection	Navisworks.Clash.Group	Groups a test's results by the model's own grid: each group is named after the nearest grid intersection and level (e.g.
Clash.GroupResultsByLevel	Navisworks.Clash.Group	Groups a test's results by nearest level below each clash point (wire your level names and elevations) — per-floor triage.
Clash.GroupResultsByProximity	Navisworks.Clash.Group	Groups a test's results into clusters whose clash points lie within a radius of the cluster seed — one issue per hotspot.
Clash.GroupResultsBySameItem	Navisworks.Clash.Group	Groups a test's results so every clash involving the same element lands in one group (named after the element) — turns thousands of raw clashes into one issue per element.
Clash.GroupResultsByStatus	Navisworks.Clash.Group	Groups a test's results by status (New/Active/Reviewed/Approved/Resolved) — one triage bucket per status in Clash Detective.
Clash.ResultsTable	Navisworks.Clash.Report	Makes a table of the clash results you wire in: one row per result with its test, group, name, GUID, status, distance, assignee, description, creation date, the two items (path and GUID) and the clash point.
Clash.RunAllTests	Navisworks.Clash.Tests	Runs every Clash Detective test in the document — the weekly coordination re-run in one node.
Clash.SnapshotToFile	Navisworks.Clash.Report	Saves a clash-run snapshot (per result: test, item identities, status, distance, clash point) as JSON — one half of the between-runs delta report.
Clash.Status	Navisworks.Clash.Tests	A clash status as a dropdown (New/Active/Reviewed/Approved/Resolved) — wire it into ClashResult.SetStatus or Clash.FilterByStatus instead of typing the text.
Clash.Statuses	Navisworks.Clash.Tests	Pick SEVERAL clash statuses with toggles — the multi-select for Clash.FilterByStatus: switch on New and Active to work everything not yet reviewed.
Clash.SummaryTable	Navisworks.Clash.Report	Per-test clash counts by status (test × Total/New/Active/Reviewed/Approved/Resolved) — the clash summary matrix.
Clash.Tests	Navisworks.Clash.Tests	All Clash Detective tests in a document, including those inside folders.
ClashGroup.ByName	Navisworks.Clash.Group	Finds a clash result group by test name + group name and opens it up: the results inside, the group's own status, and the count.
ClashGroup.Info	Navisworks.Clash.Group	Everything about a clash result group, straight from the group object — the results inside, its name and status, and the TEST it belongs to (object and name).
ClashResult.Angle	Navisworks.Clash.Results	The angle in degrees (0–90) between the two clashing elements, taken from each element's overall direction (its bounding-box diagonal).
ClashResult.Assign	Navisworks.Clash.Results	Assigns a clash result, or a whole result group, to a person or trade.
ClashResult.ByGuid	Navisworks.Clash.Results	Finds clash results again from their GUIDs — the way back from a BCF topic or a snapshot to the live result: wire the guid output of BCF.ImportIssues and send the results to ClashResult.SetStatus.
ClashResult.Center	Navisworks.Clash.Results	The clash point of a result, in document units.
ClashResult.Documentation	Navisworks.Clash.Results	How documented a clash already is — whether it has a saved viewpoint, redline markup, and how many comments.
ClashResult.Focus	Navisworks.Clash.Results	Focuses the view on clash results the way double-clicking one in Clash Detective does: hides everything else (isolate), zooms the camera to the clashing pair, and optionally selects the elements.
ClashResult.Info	Navisworks.Clash.Results	Name, status, distance, description, assignee and creation time of a clash result, plus its GUID (what BCF topics and ClashResult.ByGuid use), the name of its test and the name of its group (empty when it is not in a group).
ClashResult.Items	Navisworks.Clash.Results	The two model items involved in a clash result.
ClashResult.Orientation	Navisworks.Clash.Results	ClashResult.Angle with world context: the crossing angle PLUS each element's bounding-box shape — "slab" (thin horizontal), "wall" (thin upright), "riser" (long vertical), "run" (long horizontal) or "block" — and its slope from horizontal (0–90°).
ClashResult.Rename	Navisworks.Clash.Results	Renames a clash result or result group — with lacing and String nodes this is batch renaming ("Clash1" → "Pipe vs Duct L02-B3").
ClashResult.SaveImage	Navisworks.Clash.Results	Renders a clash snapshot (scene plus clash highlight) to a .png/.jpg/.bmp file — the picture half of every clash report.
ClashResult.SetDescription	Navisworks.Clash.Results	Sets the description text of a clash result, or of a whole result group (context for reports and reviews).
ClashResult.SetStatus	Navisworks.Clash.Results	Sets the status of a clash result, or of a whole result group (wire the group from ClashTest.Groups or ClashGroup.ByName) — approve a group in one step.
ClashResult.Size	Navisworks.Clash.Results	The size of the clash overlap region — its bounding-box volume in document units³.
ClashResult.Viewpoint	Navisworks.Clash.Results	The camera viewpoint Navisworks generates for a clash result; optionally applies it to the current view.
ClashTest.ByName	Navisworks.Clash.Tests	Finds a clash test by its display name (searches folders too).
ClashTest.ClearResults	Navisworks.Clash.Tests	Removes every result (and result group) of a clash test and leaves the test and its settings in place — the clean slate before a re-run.
ClashTest.Create	Navisworks.Clash.Tests	Creates a clash test between two item selections — script the weekly test matrix instead of clicking it.
ClashTest.Delete	Navisworks.Clash.Tests	Deletes a clash test and all of its results from the document.
ClashTest.Duplicate	Navisworks.Clash.Tests	Duplicates a clash test — type, tolerance, rules and both selections — as a new test named "<name> copy" (or newName) in the same folder.
ClashTest.Edit	Navisworks.Clash.Tests	Edits an existing clash test in place — name, test type, tolerance, merge-composites and the two selections; every input left at its default ("", "unchanged", -1, unwired) keeps the current value.
ClashTest.Groups	Navisworks.Clash.Tests	All result groups of a clash test — groups, names, each group's own status and result count, index-aligned.
ClashTest.Info	Navisworks.Clash.Tests	Name, status, type, tolerance, last run time and result count of a clash test.
ClashTest.Name	Navisworks.Clash.Tests	The display name of a clash test — the one-output companion of ClashTest.Info for wiring names into reports, group lookups and file paths.
ClashTest.Rename	Navisworks.Clash.Tests	Renames a clash test — wire a test or its current name.
ClashTest.Results	Navisworks.Clash.Tests	The individual results of a clash test (grouped results are flattened).
ClashTest.Run	Navisworks.Clash.Tests	Runs one clash test now and reports the result count.
Color Picker	Input	A color chosen with a picker.
Color.ByARGB	Color	Creates a color from alpha, red, green and blue values (0-255).
Color.ByHSV	Color	Creates a color from hue (degrees, wraps around), saturation and value (0-1, clamped).
Color.ByValues	Color	One color per value, equal values sharing a color — feed parameter values in, feed the colors to Appearance.OverrideColor per group, and use the uniqueValues/uniqueColors legend for reports.
Color.Components	Color	Splits a color into its red, green, blue and alpha channels (0-255).
Color.ContrastText	Color	Black or white, whichever reads better on a background color (WCAG contrast) — for labels on coloured fills and legends.
Color.Darken	Color	Makes a color darker by shifting its HSL lightness down by amount (0-1, clamped); alpha is kept.
Color.FromHex	Color	Parses a hex color string ("#RRGGBB" or "#AARRGGBB").
Color.Gradient	Color	A list of N colors evenly blended between two colors (endpoints included; defaults blue to red) — for heat-map style legends and value ramps.
Color.Invert	Color	Inverts a color's red, green and blue channels (the photographic negative); alpha is kept.
Color.Lerp	Color	Interpolates between two colors (t clamped to 0-1).
Color.Lighten	Color	Makes a color lighter by shifting its HSL lightness up by amount (0-1, clamped); alpha is kept.
Color.Palette	Color	A named palette as a list of colors: colourblind-safe, tableau, pastel, status (green/amber/red/grey) or the viridis, heat and grey ramps interpolated to count; fixed palettes cycle past their size.
Color.Random	Color	A pseudo-random color, stable per seed: the same seed always gives the same color (re-runs stay consistent); change the seed for another one.
Color.RandomList	Color	A list of visually distinct pseudo-random colors (golden-angle hues), stable per seed — ideal for coloring N groups apart.
Color.ToHex	Color	Formats a color as hex text, "#RRGGBB" (or "#AARRGGBB" with includeAlpha) — the reverse of Color.FromHex.
Color.ToHSV	Color	Splits a color into hue (degrees, 0-360), saturation and value (0-1); greys have hue 0.
Color.WithAlpha	Color	Returns a color with its alpha (opacity) replaced, 0 = transparent to 255 = opaque; red, green and blue are unchanged.
CSV.AppendToFile	File	Appends rows to a CSV file (same quoting and date format as CSV.WriteToFile), writing the optional headers only when the file is new or empty.
CSV.ReadFromFile	File	Reads a CSV file into a list of rows.
CSV.WriteToFile	File	Writes a list of rows to a CSV file, replacing what was there, and creates missing folders.
Date	Input	A date (and optional time), typed as 2026-10-01 or 2026-10-01 14:30.
DateTime.Add	DateTime	Adds an amount of time to a date/time in a chosen unit — seconds, minutes, hours, days, weeks, months or years (negative values go back).
DateTime.AddWorkdays	DateTime	Moves a date/time by a number of working days, skipping the weekend (Saturday and Sunday, or Friday and Saturday): Friday + 1 is Monday, Monday - 1 is Friday, Saturday + 1 is Monday.
DateTime.ByDate	DateTime	Creates a date from year, month and day numbers.
DateTime.Compare	DateTime	Compares two date/times: -1 when the first is earlier, 0 when equal, 1 when it is later.
DateTime.Components	DateTime	Splits a date/time into year, month, day, hour, minute, second, English weekday name, day of year, ISO week, ISO year and quarter.
DateTime.DaysBetween	DateTime	Returns the signed number of days between two date/times (end minus start), with the time of day as a fraction.
DateTime.Difference	DateTime	How far apart two date/times are in a chosen unit — seconds, minutes, hours, days, weeks, months or years (end minus start, so a negative number means the end is earlier).
DateTime.EndOf	DateTime	Returns the last millisecond of the day, week, month, quarter or year containing a date/time (start of the next period minus 1 ms).
DateTime.Format	DateTime	Formats a date/time as text using a .NET format string (invariant culture): yyyy-MM-dd gives 2026-07-10, dd/MM/yyyy gives 10/07/2026, HH:mm gives 14:30, MMMM gives the English month name.
DateTime.FromExcelSerial	DateTime	Converts an Excel date serial number (days since 1899-12-30, the time of day as the fraction; 46000.5 is noon) to a date/time — what Excel.ReadFromFile and Table.FromExcelFile hand over for a date cell.
DateTime.FromUnixSeconds	DateTime	Converts Unix seconds since 1970-01-01 UTC to a (UTC) date/time.
DateTime.IsWeekend	DateTime	True when a date falls on the weekend (Saturday and Sunday, or Friday and Saturday) — a mask for filtering a schedule down to working days.
DateTime.Now	DateTime	Returns the current local date and time (captured at execution).
DateTime.Parse	DateTime	Parses text as a date/time.
DateTime.Range	DateTime	Creates a list of dates from a start to an end (both included) with a step in days, weeks, months or years ("every month" lands on the same day of each month, clamped to the month's end); at most 100000 items.
DateTime.StartOf	DateTime	Returns midnight at the start of the day, week, month, quarter or year containing a date/time.
DateTime.Today	DateTime	Returns today's local date at midnight (captured at execution).
DateTime.ToUnixSeconds	DateTime	Converts a date/time to Unix seconds since 1970-01-01 UTC (a value without a time zone is taken as UTC).
Dictionary.ByKeysValues	Dictionary	Creates a dictionary from a list of keys and a list of values of the same length.
Dictionary.ContainsKey	Dictionary	Tests whether a dictionary has the given key (case-sensitive).
Dictionary.Count	Dictionary	Returns the number of entries in a dictionary.
Dictionary.FromRows	Dictionary	Builds a dictionary from a list of [key, value] rows (a later row wins for a repeated key).
Dictionary.Invert	Dictionary	Swaps keys and values into a new dictionary (values become text keys; for equal values the last entry wins).
Dictionary.Keys	Dictionary	Returns all keys of a dictionary as a list.
Dictionary.Merge	Dictionary	Combines several dictionaries into a new one; for a repeated key the later dictionary wins.
Dictionary.RemoveKey	Dictionary	Returns a copy of the dictionary without the given key (a missing key is fine).
Dictionary.RemoveKeys	Dictionary	Returns a copy of the dictionary without any of the listed keys (a key it does not have is fine).
Dictionary.SelectKeys	Dictionary	Returns a copy of the dictionary with only the listed keys, in the order they are listed (trim a property bag to the few keys a report needs).
Dictionary.SetValueAtKey	Dictionary	Returns a copy of the dictionary with the given key set or updated; the input dictionary is not changed.
Dictionary.SetValues	Dictionary	Returns a copy of the dictionary with several keys set or updated at once, from a list of keys and a list of values of the same length (the several-key version of Dictionary.SetValueAtKey).
Dictionary.ToRows	Dictionary	Converts a dictionary to a list of [key, value] rows.
Dictionary.ValueAtKey	Dictionary	Returns the value stored under the given key; a missing key is an error (Dictionary.ValueOrDefault gives a fallback instead, Dictionary.ValueAtPath follows a path into nested data).
Dictionary.ValueAtPath	Dictionary	Follows a path into nested data (the result of JSON.Parse or XML.Parse) and returns what it finds there, or a default value when any step is missing.
Dictionary.ValueOrDefault	Dictionary	Returns the value stored under a key, or a default value when the key is missing.
Dictionary.Values	Dictionary	Returns all values of a dictionary as a list.
Directory Path	Input	A path to a directory.
Directory.Copy	File	Copies a folder with all its files and sub-folders to another place (creates the destination; files already there are kept, and a file with the same name is only replaced when overwrite is true - checked before anything is copied).
Directory.Create	File	Creates a folder including any missing parent folders (does nothing when it already exists).
Directory.Delete	File	Deletes a folder (an empty one, or with its whole content when recursive is true); returns false when it did not exist.
Directory.Exists	File	Tests whether a folder exists at the given path; a file, a missing folder and a blank path all give false.
Directory.Find	File	Finds files or folders under a folder by wildcard (several allowed, separated by ";"), in every sub-folder unless recursive is off.
Directory.Move	File	Moves or renames a folder with everything in it.
Distance.BetweenItems	Navisworks.Analysis	Shortest distance between two selections, with the closest (witness) point on each side.
Divide	Math	Divides the first number by the second.
Document.AppendFiles	Navisworks.Document	Appends design files to the document — Directory.FindFiles → Document.AppendFiles → Document.Save is the Navisworks Batch Utility in three nodes.

Document.Save	Navisworks.Document	Saves the document as .nwf (references to the source files) or .nwd (a published snapshot with the appearance overrides baked in) to the given path; the extension decides.
Equals	Logic	Tests whether two values are equal, the same way as Logic.Compare with ==: numbers compare by value (2 equals 2.0), text ignores upper and lower case, text that reads as a number equals that number ("5" equals 5), text that reads as a date equals that date, and two lists are equal when they have the same items in the same order.
Excel.ReadFromFile	File	Reads an .xlsx worksheet into rows + headers + the sheet names (dates arrive as Excel serial numbers, convert them with DateTime.FromExcelSerial; .xls is not supported).

Export.IfcRoles	Navisworks.Export	Maps Navisworks source properties to IFC roles — Type→IfcElementType, Level→IfcBuildingStorey, Material→IfcMaterial, Classification→IfcClassificationReference — for Export.ToIfc.
Export.IfcSetClassMap	Navisworks.Export	Assigns an IFC class to every item of the named saved/search sets (set→class), producing the classMap for Export.ToIfc.
Export.IfcSpatialNames	Navisworks.Export	Names for the IFC spatial tree (Project/Site/Building/default Storey) used by Export.ToIfc.

Export.ViewpointImage	Navisworks.Export	Renders a view to a .png/.jpg/.bmp file via the Navisworks image exporter.
FallHazard.EdgeHandrailCheck	Navisworks.Analysis	Marks the floor edges around voids: green where the gap across the void is under the limit (safe), red where it is over the limit and there is no handrail (needs one), and blue where a handrail covers it — override any of the three colours with the colour inputs.
FallHazard.FloorOpeningMap	Navisworks.Analysis	Whole-floor fall-hazard heat map.
File Path	Input	A path to a file.
File.Copy	File	Copies a file to a new path (creates the destination folder; refuses to replace an existing file unless overwrite is true).
File.Delete	File	Deletes a file; returns true when it was deleted and false when it did not exist.
File.Exists	File	Tests whether a file exists at the given path; a folder, a missing file and a blank path all give false.
File.Hash	File	Computes a checksum of a file's content (SHA256, SHA1 or MD5) as lower-case hex text - handy for change detection.
File.Info	File	Reads a file's name, extension, folder, size in bytes and modified / created dates; a missing file gives exists = false and empty values instead of an error.
File.Move	File	Moves or renames a file (creates the destination folder; refuses to replace an existing file unless overwrite is true).
Flow.Require	Workflow	Stops with your own error message when a condition is false; when it is true the value passes through unchanged.
Flow.Then	Workflow	Passes a value through unchanged AFTER the wired 'after' nodes have run — makes the execution order of side-effect nodes explicit (e.g.
Flow.Try	Workflow	Carries on after a failure: gives the node's result, or your fallback plus the error text when that node failed — nothing after it turns red.
Flow.Wait	Workflow	Waits the given number of seconds (at most 600; nothing can stop the wait early, so Navisworks looks frozen meanwhile), then passes the value through unchanged - use it to pause between steps of a workflow.
Flow.When	Workflow	Runs the nodes wired after it only when the condition is true; when false they are skipped (idle, not an error) — e.g.
Graph.Folder	System	The folder of the graph file, which is where a relative path in a file node starts (for a graph that was never saved: Documents\CamelGraph; in the Script Player and the command line: the folder of the script).
GreaterThan	Logic	Returns true when the first number is greater than the second.
GreaterThanOrEqual	Logic	Returns true when the first number is greater than or equal to the second.

If	Logic	Returns one of two values depending on a boolean condition.
IFC.GuidDecode	IFC	Converts a 22-character IFC GlobalId such as "0$WU4A9R19$vKWO$AdOnKA" back to a standard lower-case hyphenated GUID — the form Navisworks shows as an item's GUID.
IFC.GuidEncode	IFC	Converts a standard GUID such as "3f81e10a-25b0-49ff-9520-63f2a763150a" to the 22-character IFC GlobalId (the IFC base-64 form, alphabet 0-9 A-Z a-z _ $) — the format of IFC files and BCF references.
IFC.IsGlobalId	IFC	True when a text is a 22-character IFC GlobalId (alphabet 0-9 A-Z a-z _ $, first character 0 to 3) and false for a plain GUID, any other text or an empty cell, so a column that mixes both forms can be split before IFC.GuidDecode or IFC.GuidEncode.
IFC.Normalize	IFC	Writes an id in one form whichever form it comes in: a 22-character IFC GlobalId or a standard GUID (with hyphens, without, or in braces) becomes the form you choose, a GlobalId (default) or a lower-case hyphenated GUID.
Integer	Input	A whole number (no slider range): a count, an index, a level.
Integer Slider	Input	An integer selected with a slider.
IsNull	Logic	True when the value is null (nothing came out).
IsNullOrEmpty	Logic	True when the value is null, an empty string, an empty list or an empty dictionary — the guard for "did anything come out?" checks before If branches.
JSON.Parse	Data	Parses a JSON string into dictionaries, lists and values.
JSON.ReadFromFile	File	Reads a JSON file into dictionaries, lists and values (every number becomes a double).
JSON.Stringify	Data	Serializes any value to a JSON string.

List.AddItemToFront	List	Returns a new list with the value prepended — the front-side twin of List.AddItemToEnd.
List.AllIndicesOf	List	Every zero-based index at which the item occurs in the list — List.IndexOf finds only the first.
List.AllTrue	List	True when EVERY element of the list is true — collapse a mask into one verdict.

List.Average	List.Statistics	The arithmetic mean of the numbers of a list.
List.Chop	List	Chops a list into consecutive sublists: one length chops evenly ([1..7] by 3 → [1,2,3],[4,5,6],[7]); a list of lengths is applied in sequence and repeats until the input runs out (Dynamo behavior).
List.Clean	List	Removes null elements from a list, at every nesting level — the mop-up after laced calls that emitted nulls for missing elements (a yellow node badge points here).
List.Contains	List	Tests whether a list contains a value.

List.DropItems	List	Drops elements from the start of the list — or from the END with a negative amount (Dynamo behavior).
List.DropWhile	List	Drops items from the start of the list for as long as the mask is true; keeps everything from the first false.

List.FilterByBoolMask	List	Splits a list into elements whose mask entry is true ("in") and the rest ("out").
List.FilterByValue	List	Keeps the items that pass a test such as > 100, contains "wall", matches "A-*" or in ["L01", "L02"] — optionally testing a parallel list of keys instead; returns the matches, the rest and the mask.
List.FirstItem	List	Returns the first element of a list.
List.Flatten	List	Flattens a nested list by a given number of levels (-1 = completely).
List.GetItemAtIndex	List	Returns the element at the given index (negative indexes count from the end).
List.GroupByKey	List	Groups list elements by a parallel key list of the same length; returns the groups (in the order each key first appears) and their unique keys.

List.IndexOf	List	Returns the index of the first occurrence of a value in a list (-1 when absent).
List.Insert	List	Returns a new list with the value inserted at the index (0 = front; the list's length = append; negative counts from the end).

List.LastItem	List	Returns the last element of a list.
List.MaximumItem	List	The largest element of a list (numbers, texts or dates).
List.Median	List.Statistics	The middle value of the numbers of a list (the mean of the two middle ones when the count is even); the same as List.Percentile at 50.
List.Merge	List	Concatenates any number of lists into one — a multi-input socket: connect as many wires as you like, in the order you want them.
List.MinimumItem	List	The smallest element of a list (numbers, texts or dates).
List.MostCommon	List.Statistics	The value that occurs most often in a list (the earliest wins a tie) and how many times.
List.OfRepeatedItem	List	A list of one value repeated N times — constant columns for tables, or a fixed pairing partner under Longest lacing.
List.Pairs	List	Pairs each item with the next one: [[a, b], [b, c], …] — consecutive points, segments, steps.
List.Percentile	List.Statistics	The value below which a given percentage of the numbers lie (linear interpolation, like Excel's PERCENTILE.INC); 50 is the median, 0 the smallest and 100 the largest number.
List.Product	List.Statistics	Multiplies the numbers of a list.
List.Range	List	Creates a sequence of numbers from start to end (both included) using the given step; a negative step counts down, a step that moves away from end gives an empty list.

List.ReplaceItemAtIndex	List	Returns a new list with the element at the index replaced (negative indexes count from the end).
List.ReplaceNulls	List	Replaces every null element with a substitute value, at every nesting level — keeps list lengths and alignment intact where List.Clean would shift them.
List.RestOfItems	List	Everything but the first element — pairs with List.FirstItem for head/tail processing.

List.SetUnion	List	The distinct elements present in EITHER list (first-seen order) — combine two item sets without duplicates.
List.ShiftIndices	List	Rotates the list: +1 moves every element one place towards the end and wraps the last to the front ([a,b,c] → [c,a,b]); negative rotates the other way.
List.Shuffle	List	Shuffles a list; the same seed always gives the same order, so a run can be repeated.
List.Slice	List	A sub-range of the list: from start (inclusive) to end (exclusive), taking every step-th element; leave end empty to go to the end of the list.
List.Sort	List	Returns the list sorted ascending, or largest first with descending.
List.SortByKey	List	Sorts list elements by a parallel key list of the same length, smallest key first or largest first with descending; returns the sorted elements and keys.
List.StandardDeviation	List.Statistics	The standard deviation of the numbers of a list (population by default; tick 'sample' to divide by n-1, which needs at least two numbers).

List.WithIndex	List	Pairs each item with its position: [[0, item0], [1, item1], …].
List.Zip	List	Pairs two lists by position: [[a0, b0], [a1, b1], …], as long as the shorter list.
Log.Write	File	Appends one line "yyyy-MM-dd HH:mm:ss LEVEL message" (local time) to a log file and returns that line.
Logic.Choose	Logic	Picks one of several options by position (0 = first) — a multi-way If.
Logic.Compare	Logic	Compares two values — numbers, text or dates — with a test chosen from a list (==, >, contains, matches, regex …).
Logic.IsBetween	Logic	True when a number, text or date lies between a lower and an upper bound (bounds included by default).
Logic.NotEquals	Logic	True when two values are different — the opposite of Equals, with the same rules: numbers compare by value, text ignores upper and lower case, text that reads as a number or a date is compared as one, and two lists are equal when they have the same items in the same order.
Logic.Switch	Logic	Gives the result that goes with the first case equal to the value, otherwise the fallback — a status-to-colour or code-to-name mapping.
Logic.TypeOf	Logic	Names the kind of a value — number, text, boolean, datetime, list, dictionary, null or the object's type — for debugging what a node really returns.
Logic.Xor	Logic	True when exactly one of the two inputs is true.
Loop.Collect	Workflow	Closes a loop and collects one value per iteration.

Math.IsClose	Math	True when two numbers differ by no more than the tolerance (the same unit as the numbers) — the safe way to ask "are these equal?" for lengths and levels read from a model, where 0.1 + 0.2 is not exactly 0.3.
Math.Lerp	Math	Linear interpolation: a at t = 0, b at t = 1, in between for values between (not limited, so t = 2 goes past b; Math.Clamp keeps t in 0 to 1).

Math.Negate	Math	Flips the sign of a number (5 becomes -5).
Math.Percent	Math	What percentage the part is of the total (37 of 340 gives 10.88); 0 when the total is 0, so an empty model reads 0 % (Divide, in contrast, gives Infinity for a zero divisor).

Model.Remove	Navisworks.Model	Removes a WHOLE appended source model from the document (accepts a Model, a 0-based index, or a file name).
Model.Snapshot	Navisworks.Model	Captures the named properties of the given items as a dictionary keyed by each item's instance GUID (items without one are keyed "path:" plus their tree path) — the input Snapshot.Diff compares, so save one with JSON.WriteToFile now and diff it against a later run to see added, removed and changed items.
Model.Statistics	Navisworks.Model	Counts items per model file, class or layer: how many items, how many carry geometry and each group's share of all items.
ModelItem.AncestorNameMatches	Navisworks.ModelItem	Walks an item's ancestor chain (nearest first) and tests each name against the text: contains / starts with / ends with, or their "doesn't" negations — true when NO ancestor matches.
ModelItem.AncestorPropertyMatches	Navisworks.ModelItem	The general form of ModelItem.AncestorNameMatches: walks an item's ancestor chain (nearest first) and tests ANY property you name — category + property as the Properties window shows them — against the text: contains / starts with / ends with or their "doesn't" negations (true when NO ancestor matches).

ModelItem.GetTransform	Navisworks.Transform	Reads an item's current (active) transform: origin = its translation (a practical base point), matrix = 16 numbers row-major (feed ModelItem.SetTransform to round-trip), hasOverride = whether a permanent transform override is applied.
ModelItem.IfcGuid	Navisworks.ModelItem	The 22-character IFC GlobalId of an item: the value of its GlobalId / IfcGUID / IFC GUID / Guid property when it has one (as the Navisworks IFC import creates it), otherwise its InstanceGuid encoded the same way; null when it has neither.
ModelItem.Info	Navisworks.ModelItem	Everything quick to know about a model item in one node: its display name (the class name when it has none), class name and localized class name (layer/group/geometry detection), instance GUID ("" when absent, a stable cross-run identity for reports), whether it carries geometry and whether it is hidden right now.
ModelItem.ModelName	Navisworks.ModelItem	The name of the model/file an item comes from (the root of its selection tree, e.g.
ModelItem.MoveTo	Navisworks.Transform	Moves model items so the centre of their combined bounding box lands on a target point — place a group by where it should be, not by how far to push it.
ModelItem.Parent	Navisworks.ModelItem	The parent of a model item (null for a model root).
ModelItem.Path	Navisworks.ModelItem	The selection-tree path of an item as one text, from its model file down to the item ("Structure.nwc > Level 1 > Walls > Basic Wall") — a label for BCF titles, clash names and reports.
ModelItem.ReferencePoints	Navisworks.ModelItem	Candidate base/reference points of an item, in world document units.

ModelItem.RotateAboutAxis	Navisworks.Transform	Rotates model items by an angle (degrees) about an axis through a point.
ModelItem.Scale	Navisworks.Transform	Scales model items uniformly about a point — default: the centre of the items' combined bounding box, so the group grows or shrinks in place and keeps its internal layout.
ModelItem.SetTransform	Navisworks.Transform	Sets the permanent transform override of model items to an absolute 4×4 matrix (16 numbers, row-major, translation at indices 3/7/11) — mirror-place or scale-in-place for power users.
ModelItem.SourceInfo	Navisworks.ModelItem	One-node answer to "which file did this element come from and what is it": the source file name, the Item-tab Type (falling back to the item's class name), and the owning appended model.

Path.Combine	File	Joins a folder path and a file name with the correct separator.
Path.GetDirectory	File	Returns the folder part of a path ("C:\Models\site.nwd" gives "C:\Models"); empty text for a root or a bare file name.
Path.GetExtension	File	Returns the extension of a path with its leading dot (".nwd"), or empty text when there is none.
Path.GetFileName	File	Returns the file name of a path including its extension ("C:\Models\site.nwd" gives "site.nwd").
Path.GetFileNameWithoutExtension	File	Returns the file name of a path without its extension ("C:\Models\site.nwd" gives "site").
Path.GetFullPath	File	Resolves a path to an absolute path the way the file nodes do: a relative path starts in the graph's folder (the folder of the saved graph file; Documents\CamelGraph for a graph that was never saved), and the quotes of a path pasted from Explorer are removed.
Path.GetRelativePath	File	Expresses a path relative to a base folder; returns the full path when they are on different drives.
Path.IsAbsolute	File	Tests whether a path is absolute (starts at a drive, network share or root) rather than relative.
Path.Join	File	Joins any number of folder and file name parts into one path with the correct separator, for example C:\Projects + North + HVAC + model.nwd.

Point.Midpoint	Geometry	The point halfway between two points.
Point.Round	Geometry	Rounds a point's X, Y and Z to the given number of decimal digits (midpoints round away from zero) — tidies float noise before comparing or grouping points.

Properties.AsDictionary	Navisworks.Properties	Every property of an item flattened to a "Category.Property" → value dictionary (full data dump).
Properties.Categories	Navisworks.Properties	The property category names available on a model item.
Properties.CustomTabs	Navisworks.Properties	The user-defined property tabs on an item (discovery/QA before SetCustom or RemoveCustomTab).
Properties.Discover	Navisworks.Properties	Lists every property the given items carry, one row per category and property with how many items have it (Items), how many different values it holds (Distinct, counted up to 10000) and the first few values (Samples) — the answer to "what data does this model actually have?".
Properties.HasProperty	Navisworks.Properties	True when the item carries the property — drives model-QA missing-data masks.
Properties.InCategory	Navisworks.Properties	All property names and values inside one category of an item.
Properties.RemoveCustomTab	Navisworks.Properties	Removes a user-defined property tab from items.
Properties.RenameCustomTab	Navisworks.Properties	Renames a user-defined property tab in place (same properties, same internal name — search sets targeting the tab stay valid).
Properties.SetCustom	Navisworks.Properties	Writes ONE set of names and values as a user-defined property tab onto every item you give it — values are searchable, schedulable, and travel with the NWF/NWD (source files are never modified).
Properties.SetCustomFromTable	Navisworks.Properties	Writes a table onto model items as a user-defined property tab, a DIFFERENT row for every item — the spreadsheet-to-model step in one node (Table.FromExcelFile, Table.Join with Properties.ToTable, then this).
Properties.ToTable	Navisworks.Properties	Reads the named properties of every item into a table with one row per item and one column per name ("Element.Category", "Item|Layer", a bare property name, or @Name, @Path, @Guid), ready for the Table nodes, Excel or CSV; a property an item lacks is an empty cell.
Properties.Value	Navisworks.Properties	Reads a property value from a model item, converted to a plain value.
Properties.ValueAsString	Navisworks.Properties	Reads a property value as text.
Proximity.Cluster	Navisworks.Analysis	Groups items into clusters of touching geometry (gap <= tolerance, chained) — turns loose shapes into logical elements, e.g.
Proximity.NearestDistance	Navisworks.Analysis	For each item, the distance to the NEAREST of the targets (document units), so you can flag items with nothing close by — e.g.

SavedViewpoint.Delete	Navisworks.Viewpoints	Deletes a saved viewpoint: wire the viewpoint itself (so exactly that one goes, whatever its folder), or its name, or its folder path and name ("Reviews/Week 12/Level 1").
SavedViewpoint.Duplicate	Navisworks.Viewpoints	Duplicates a saved viewpoint in its folder, copying its camera and any baked appearance overrides.
SavedViewpoint.Folder	Navisworks.Viewpoints	The folder containing a saved viewpoint: its path as "A/B" ("" for top-level viewpoints) and the folder itself — drives folder-based status workflows.
SavedViewpoint.Info	Navisworks.Viewpoints	Reads a saved viewpoint: its name, folder path ("A/B", "" at the top level), whether it carries a section box, whether it has baked appearance or visibility overrides, its comment count and its camera — the position and the look-at point (one focal distance ahead of the camera, or one unit when none is stored).

Search.ByGuid	Navisworks.Search	Finds the items whose instance GUID equals any of the given GUIDs (text, a 22-character IFC GlobalId, or GUID values) in one pass over the model — not one search per GUID — and lists the GUIDs that matched nothing; walks every item of the document once (O(items)).
Search.ByProperty	Navisworks.Search	Finds every model item by one property, like Find Items with its condition drop-down: equals a value, contains text, matches a wildcard pattern (* and ?), is >, >=, < or <= a number (e.g.

Selection.Current	Navisworks.Selection	The model items currently selected in Navisworks, read again on every run (press Run after selecting something else and the new selection comes through).
Selection.Invert	Navisworks.Selection	The items that are NOT in the current selection (Navisworks' own invert, so whole untouched branches come back as one item each); it does not change the selection — wire it into Selection.SetCurrent to select them.
Selection.Remove	Navisworks.Selection	Takes the given items out of the current Navisworks selection and returns what is still selected; items that are not selected themselves (for example children of a selected parent) are ignored.

SelectionSet.Create	Navisworks.SelectionSets	Creates a saved selection set from the given items, filed in the folder you name (a folder from SelectionSets.CreateFolder, a folder name, or a path such as "Walls/Level 1"; a folder that does not exist yet is created; empty means the top level).
SelectionSet.CreateFromSearch	Navisworks.SelectionSets	Creates a live SEARCH set from a property rule, with the same modes as Search.ByProperty (equals, contains, wildcard, >, >=, <, <= or exists; a list in value means any of its entries) — it re-evaluates as the model changes, so "Diameter > 100" or "Name contains DEMO" stays up to date.
SelectionSet.Delete	Navisworks.SelectionSets	Deletes a saved selection or search set by name (searches folders too).
SelectionSet.Duplicate	Navisworks.SelectionSets	Duplicates a saved selection or search set in its folder (a search set stays a live search); the copy is named "<name> copy" unless newName is given.
SelectionSet.Info	Navisworks.SelectionSets	What a saved set is: its name, whether it is a fixed "selection" or a live "search" set, how many items it selects right now (a search set is evaluated once to count; turn includeCount off when you only need the name, kind or folder of many sets) and its folder path ("" at the top level).

SelectionSets.InFolder	Navisworks.SelectionSets	All saved selection and search sets inside a folder, in Sets window order.
SelectionSets.RenameFolder	Navisworks.SelectionSets	Renames a Sets window folder (accepts the folder, its current name or a path like "Walls/Level 1"; searches nested folders too).
SelectionSets.SortFolder	Navisworks.SelectionSets	Sorts a Sets window folder's contents alphabetically by name (A to Z, ignoring case; entries with the same name keep their order) so you never drag sets into order again.

Table.Info	Table	How many rows and columns a table has, and its column names (the headers output is the list of names, in column order).
Table.Join	Table	Joins two tables on one or more key columns (inner, left or outer) — add the Excel columns to the model data by GUID or mark.
Table.Pivot	Table	Cross-tabulates: rows from one column, columns from another, each cell the sum (or count, average …) of a third — clashes by level and status.

Table.Unmatched	Table	The rows of the left table that find no partner in the right table, using the same keys and the same matching as Table.Join (GUIDs match whatever their case, a blank key never matches) — which model elements have no row in the Excel list, which GUIDs were not found.
Takeoff.SumPropertyByGroup	Navisworks.Analysis	One-node QTO rollup: groups items by a property value and sums a numeric property per group (e.g.
