Health Score
One number. Zero configuration.
Unlike Solibri's rule-based approach that requires hours of setup per project, IFC Viewer Online runs 38 checks automatically and gives every model a Health Score from 0 to 100 — in under 30 seconds.
No ruleset to configure
38 rules run automatically. No XML, no .smc files, no per-project setup. Open a file and get a score.
Results in under 30 seconds
A background Web Worker processes rules concurrently. Issues stream in as each check completes — the UI stays responsive throughout.
Share the report

Fix, not just read
GUID duplicates auto-fix with one click. Edit names and property values inline. Export the corrected IFC — all in the browser.
38 validation rules
What gets checked
Rules span schema quality, spatial hierarchy, ISO 19650 compliance, LOD completeness, and coordination checks.
GUID checks
Duplicate GlobalIds, invalid base64 format. Most common export error from Revit, ArchiCAD, Tekla. Auto-fixable with one click.
Spatial hierarchy
IfcSite → IfcBuilding → IfcBuildingStorey chain. Orphan elements with no spatial containment. Missing project context.
Naming & ISO 19650
Empty Name / LongName attributes. Generic placeholders. Naming convention patterns configurable per project.
Property sets
Missing required Psets for walls, slabs, columns, beams. Empty or null property values that break downstream QTO.
LOD completeness
Verifies expected property sets are present at LOD 200 / 300 / 400 for common structural element classes.
Schema & geometry
IFC schema version compatibility, unit assignments, type assignments, material associations, degenerate geometry.
FAQ
Questions
Is IFC Viewer Online a good replacement for Solibri Anywhere?
For individual BIM Coordinators who need to check IFC models before delivery — yes. It runs 38 validation rules in your browser with zero setup, gives a Health Score from 0 to 100, and lets you fix GUID errors and export a corrected IFC without a server. It also supports full IDS 1.0 validation — load a buildingSMART .ids file and check your model against it locally. It does not yet offer multi-user cloud workflows, but for the core pre-delivery check workflow it is a practical, free, and private replacement.
What happened to Solibri Anywhere?
Solibri Anywhere, the free tier of Solibri Model Checker, was discontinued on April 13, 2026. Users who relied on it for basic IFC viewing and quality checking now need an alternative. The paid tiers of Solibri Model Checker remain available at €495–€2,772/year.
Does IFC Viewer Online work on Mac?
Yes. Unlike Solibri Anywhere (Windows-only desktop app), IFC Viewer Online works in any modern browser on Mac, Windows, and Linux. Chrome, Edge, Firefox, and Safari are all supported. No plugin, no installation required.
Can I use it with confidential models under NDA?
Yes. All processing happens in your browser via WebAssembly — no data is ever transmitted to any server. You can safely use it with confidential project models under NDA. There is no service agreement to review with your client.
Is there a file size limit?
There is no hard limit — the validator handles files up to ~2 GB. Performance depends on your device. Files under 200 MB load well on most modern hardware. Parsed geometry is cached in the browser's Origin Private File System (OPFS) so subsequent loads of the same file are instant.
Does it have BCF export like Solibri?
Yes. After running validation, you can export all issues as a BCF 2.1 file for coordination with Navisworks, BIMcollab, and other BCF-compatible tools. Individual issues can also be added to a BCF topic directly from the issue panel.
