thatopen-impl-clipping-plans

You create floor plans and cross-sections in a ThatOpen BIM viewer by using v3 Clipper for plane creation, ClipStyler for styled cut visualization, and Views to open orthogonal section views synced with the camera.

v2 Plans and standalone ClipEdges are deprecated and removed in ThatOpen. You must migrate to the v3 workflow using Views and ClipStyler to generate clipping planes and section visualizations.

To set up ClipStyler styles for cross-section visualization, define your named styles and classification-based item groups before using createFromView or createFromClipping, and ensure clipStyler.world is properly set.

Yes, you can create clipping planes programmatically from a normal and coplanar point or from IFC storeys. You use Views.open to activate the orthogonal section view and automatically enable clipping for the active view.

Interactive draggable clip planes in ThatOpen are created using the v3 Clipper via raycast and drag. You link these planes to predefined ClipStyler styles to produce styled edge outlines and fills for each cut.

Yes, you need to enable Clipper and set clipStyler.world before activating orthogonal section views with Views.open. Defining ClipStyler styles beforehand ensures correct visualization when the view is opened.
