Wow, thanks guys for the prompt input.
I think I understand what you have both described.
Unfortunately I'm running SW2007 and can't open your sample. But I will be playing with your ideas this morning.
Mabye some more ideas will keep coming. This type of thing was so easy in 2D autocad...

Should it all be one part, or an assembly...
