Editorial interest 78/100 Selection signal · not a rating of the site

A free browser tool for opening IFC building models and exploring their 3D geometry, structure, and embedded data.

Landing page captured for the 2026-10-01 issue.

For: Architects, engineers, and contractors inspecting IFC models
Worth noticing: It accepts uncompressed IFC2X3 or IFC4 files up to 64 MiB and 500,000 entities; IFC4X3, IFCZIP, and Revit files are excluded.

Field notes

The viewer offers camera presets, class colouring, hierarchy browsing, and filters for storey and class, then exposes properties and quantities when those records are present in the model. Its stated file ceiling is 64 MiB and 500,000 entities, though additional geometry limits are not specified here. Optional browser storage keeps a saved copy on that device; the page says its URL alone does not share the model.
