I am stuck.
I can't get the issue to appear on PC.
A few MAC users have had issues, but I haven't been able to track-down the problem...
If you try the tools when the Ruby Console is open are there any error massages ?

I also met the such problem. I did some tests and found the possible problem.
For the 2dArc Tool:
Steps:

1. Click
2. Move on the screen
3. Click
4. Move on the screen
   After step 4, SketchUp crashed.(Only on MacOS, Windows is fine)

Possible Reason:
After step 3, the view will draw a line, which presents two points the arc will pass through.
In Step 4, the 2dArc tool will create a temporary arc, get the points of this arc, then remove the arc, and draw lines of those points. Those operations will execute when the mouse moves, and this may consume large CPU resources.

If I remove these operations, then the tool works well. But I don't know why Sketchup only crashes on MacOS.

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?
