Well...I'm back.
My Model has 8 groups. MAIN, BOGIE1, BOGIE2, COUPLERS, WHEELS11, WHEELS12, WHEELS21 WHEELS22.
It's a Sketchup model imported in 3DC.
After the import, on the far right box, the above 8 names don't show after I click on a cube.
Instead I have 180 cubes named "group".
When I click on the "+" key, I get stuff named mesh followed by a number.
I did this all correct last week and now I suffer from CRS!! And I didn't save that test model to fall back to see how I set it up!! (Yeah, I know, STUPID IS STUPID DOES)
So what am I doing wrong?
