WHAT IT DOES

What clear_selection_set does on Pypi:best Cad

AI agents use clear_selection_set to create or update resources in Pypi:best Cad, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Pypi:best Cad environment.

RISK

Why clear_selection_set is rated Medium

The tool clears/empties a selection set in AutoCAD but explicitly does not remove entities — it only deselects them. This is a reversible state change (modifying the selection set object), so it qualifies as Write. It has low severity since no geometry is altered or deleted.
