Crate geop_cad_base 

What an interactive CAD editor needs from the kernel beyond building parts (which geop_ops_parts does): picking entities in the viewport.

Modules

pick

Ray-based hit testing (“picking”) against a Model, for interactive selection in a viewer: cast a ray from the camera through the cursor, ask for the nearest vertex/edge/face/solid it hits, and get back its id — which a caller turns into the entity’s stable name to put into a program step.
