How it works

Try it

The saved viewpoint opens automatically. A rectangle marks the stair opening and an arrow leads from the approach toward the landing. The close oblique section exposes the stair flight, handrail and neighboring rooms. Orbit or zoom to inspect the relationship, then click Restore annotated view to return to the review camera.

Open Topics (speech bubble) on the left toolbar and select Review stair opening protection to read the coordination note. Select a component, then click 1 element selected at the top left to open Properties.

Developer integration

This page imports the full BIM Whale Advanced Project and an existing BCF 3.0 archive embedded in the inline configuration. The archive already contains a bold closed rectangle and arrow built from closely spaced BCF line segments, an orthogonal camera and six clipping planes. The review geometry uses the pinned model's Z-up world coordinates in meters. The lines and saved camera are authored inputs; the page does not generate annotations from IFC properties.

bcf.load() reads the saved topic identifier, viewer.add() imports the original archive bytes, and viewer.selectTopic() restores the annotated view. The SDK renders the model and annotations together. Restoring the view reuses the imported topic. Retry sample retains completed imports.

Copy this folder and serve it over HTTP, for example python -m http.server 8080. The published SDK and full model download require internet access.

Saved coordination markup

The review note, outline, arrow, camera and section box were authored for this example and saved in the embedded BCF archive. They illustrate a guarding review at the stair opening; they are not an issue report from the model author.
