Health Score and Fix this first → a live city twin → sun and climate → point clouds → Clip Studio. All in your browser. Try it live →

In one sentence: drag in one IFC or a whole federated project, see it in 3D (on a real map if you want), get a Health Score with the issues to fix first, fix the common ones in a click, measure and compare versions, and export a corrected file, BCF or report. Nothing is uploaded to a server.

What it does

Check and fix models

Capability	What you get
IFC Health Check	44 validation rules streamed live from a Web Worker, summarized as one Health Score (0–100), with a Fix this first list right under the score and Show in 3D on every row.
One-click fixes	A browser engine that fixes missing types, renames every duplicate or empty name in one go, and suggests the real class for IfcBuildingElementProxy elements. You see the Health Score of the fixed file before you download it.
Fix guides	Step-by-step remediation per rule for Revit, ArchiCAD, Tekla and Allplan. The guide opens on the tool the model was exported from. Also published as static /fix/ pages in 10 languages.
buildingSMART IDS 1.0	Load an .ids file and check the model against it: all six facets (entity, attribute, property, classification, material, partOf), tested against the official buildingSMART test cases. Export to JSON / CSV / HTML / BCF.
EIR profiles and requirements	Build an Exchange Information Requirements profile (or import it from an Excel template) that compiles to IDS, and share a requirements link with suppliers.
Version compare	Compare sets of IFCs between deliveries by GlobalId, check that IDS compliance did not regress, and sync the BCF issue list. See docs/VERSION_COMPARE.md.
Non-destructive editor	Edit properties, fix GUIDs, rename elements. Every change is a diff with undo/redo; the corrected IFC is written in a worker.
BCF 2.1 / 3.0	Import, create and comment topics in a BCF panel; viewpoints, measurements and validation findings travel inside the issue. Works with Navisworks, BIMcollab, Solibri and any BCF-compatible CDE.
Reports	Shareable, crawlable report links, a verifiable certificate, COBie export and validation export to JSON / CSV / BCF.
