How it works

Review widths

Move the width slider. Amber windows meet the threshold; blue windows are narrower. Select a window, then click 1 element selected at the top left for Properties.

Developer integration

The component identifiers, names, dimensions and memberships are queried through the native viewer.IfcAPI. The original IFC2x3 file is hash-verified and imported unchanged. BCF views are written with bcf.save(), imported with viewer.add(), and applied with viewer.selectTopic(). Open Topics (speech bubble) on the left toolbar to inspect the generated viewpoint.

The page reads each window’s OverallWidth attribute and the project length unit, converts widths to millimetres, then builds the two color sets at runtime.

The page opens the original source bytes with await viewer.IfcAPI, reads native model data, then closes the model and disposes WASM before displaying the source with viewer.add(). See the complete web-ifc API reference.
