Hi, thanks for this plug-in, this is what I was looking for! But it dodn't work for me. I do everything like in your video but mistake "Selection NOT 2 C of G Groups!".
I am sure that I have two Groups (see in apdx). I try do the same with two Components and there is mistake : "Selection is NOT group!".
What I do bad? I have Sketchup 2018.
Thank you for help!
