I am looking for this as well...!
Hope someone will make this a ruby...
like angular dimension...
For now...I sketch in top view...up along green axis...
(the text will align to screen...to the right)...
the dimensions is put on one by one...
from midpoint of component to starting point(zero)...
each has text position set at start...
I have an example jpg to show...but do not know how to insert here...
Edit: Thank you Dan for assistance...!
Greetings Jakob.
But as I wrote, it's neither in the menu nor right-clicking the groups does show the plugin...
