WHAT IT DOES

What set_active_ucs does on Pypi:best Cad

AI agents invoke set_active_ucs to trigger actions in Pypi:best Cad. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

RISK

Why set_active_ucs is rated High

This tool activates/switches the User Coordinate System in AutoCAD, which is an external operation with side effects on the CAD environment. It doesn't merely read data, but changes the active state of the application. It's not destructive (reversible by switching back), so Execute is the most appropriate category.

From the tool's definition 激活指定的UCS (Activate the specified UCS) — triggers an external CAD operation that changes the active User Coordinate System in AutoCAD.

set_active_ucs Rate-limited

set_active_ucs stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
