Download my 2Dtools... http://sketchucation.com/pluginstore?pln=2Dtools
The 2Darc tool RB includes code for making an Arc by included angle.
You can probably borrow some ideas/code from that...

Hi,
I've tried this extension, it works fine on windows, but on MacOS, when I try to draw arc with this tool, the sketchup seems to run into a dead loop(the mouse is busy, and can't do anything else except close sketchup).

I'm using Sketchup pro 2022/2021, did you know what happened?
