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 ?

No messages. One thing I come in mind; just before this started I got the "unexpected file format" error message on one of my models. I did not use 2dtools in that project but the problems started right after that.

anyways, I can live without that tool so no need to do alot of work and errorhunting.
I use many of your tools every day. Thanks for all the work and good tools!

No known issues about this...
If you work in an empty new model is it the same ?

yes, fresh install, different empty templates, inches, mm, cm.... etc, make no difference.
It freezes when I try to use the rectangle, circle, arc tools. The line and text tool is working. On page 25 in this tread there are several reports on the issue. the user "rdube" amon others. https://sketchucation.com/forums/memberlist.php?mode=viewprofile&u=561750.

I work on a iMac (Retina 5K, 27-inch, Late 2015) with Mac OS 10.14.6 (18G9323)
8GB RAM and AMD Radeon R9 M395 2 GB

Installed the latest version 7.7. It worked for a couple of hours but started to freeze when using the rektangle, arc, etc. The line tool works just fine. Did a fresh install of sketchup (21.1.331) an have no other extentions installed but 2Dtools an debabelizer. It is strange but it just stopped working. Not knowing for sure but i think it started after playing around with the different line weights/types.
