WHAT IT DOES

What trim_entity does on Pypi:best Cad

AI agents use trim_entity 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 trim_entity is rated Medium

The tool modifies existing drawing entities by removing or altering portions of them, which is a reversible write operation on CAD data. It does not delete entire entities (would be Destructive) nor execute arbitrary code (would be Execute). The modification is geometric but reversible through undo operations typical in CAD software.

From the tool's definition Tool name 'trim_entity' and description indicating it trims/cuts entities by removing portions that exceed boundaries (修剪实体、切除超出边界的部分). This modifies CAD drawing geometry.
