TIG please help!
The Center of Gravity tool works great, but I can't get Composite C of G to work.
I select two C of G groups,
then I go to Extensions>C of G...>Composite C of G
and it looks as though another group is generated, but it's empty
Running SketchUp Pro 17.2.2554 on MacOS 10.13.4
Thanks for any help you can offer
