Thanks, it solved the problem.

Another option: disable object snaps

It's probably OSMODE. When the pickbox on the screen is as large as the polyline's movement, if the 'endpoint' object snap is enabled, then (command "_pline" ...) it won't be able to avoid the OSMODE magnet. But if you zoom in, the pickbox will be smaller, and the problem won't occur. So, simply write on the first line of code: (setvar "OSMODE" 0)

It’s just another tool in the toolbox, right? acedTraceBoundary is a good option too

With shapely, you can make computations without the having the entities in the drawing. There are other calculations too https://shapely.readthedocs.io/en/stable/manual.html
