Frequently asked questions
Are the tools really free?
Yes — every tool, not a limited trial. Guests get 3 runs a day with 25 MB uploads; a free account raises that to 10 runs a day and 100 MB. Paid plans lift the caps further, but no plan unlocks a tool the free tier doesn't already have.
What's the maximum IFC file size?
Up to 25 MB as a guest, 100 MB with a free account, 500 MB on Pro, and 1 GB on Team. The caps are on upload size only — every tool itself is available on every tier.
Do I need an account to use the tools?
No. Every tool runs as a guest — open the sample building or drop your own IFC and go. A free account only raises the caps (bigger files, more runs a day) and keeps your workspace history; it never gates a tool.
What happens to my file after processing?
Your file is uploaded over HTTPS and processed on our servers. Guest uploads are stream-only — the working files are deleted as soon as your download finishes. Free accounts keep results for 7 days; Pro keeps them 90 days and Team 180 days. Files are never shared with third parties or used to train AI.
Which IFC versions do the tools support?
IFC2x3 and IFC4 — the two schema versions essentially every AEC authoring application exports. IFC4x3, the infrastructure schema, works too: it opens in the viewer, and validation, health reports, property-set editing and georeferencing all run on it. Tools that need geometry processing, such as clash detection and 3D export, aren't verified on IFC4x3 yet.
