How to subtract grouped objects?
Read 403 times

Having search the forum & manuals I have found nothing that relates to my queries.
So I assume it's just me but here goes...

Question 1
I have two grouped assembly's of 3d objects, essentially a fabricated (stud) wall and a fabricated door.
I need to 'cut out' (subtract) the door shape from the wall.
 
Is there a quick way of doing this without resorting to the long hand method of exploding the wall group and doing a local edit (3D Subtract does't work with blocks or groups) ?

Question 2 
Is there a way of re-grouping previously exploded groups ?

Question 1: I don't think so.

Question 2: After exploding the Group, and while its former members are still selected, place them on a Layer all by themselves. To re-group them, click on the layer name in the Design Director and press Ctrl+S to select them all, and then press Alt+Shift+G.

Not in this case, Tim. After clicking the layer name in the DD, Ctrl+S selects all the objects on that layer. Try it.

Aha, I see now.

My problem, is that I have to use the On-Screen Keyboard. 
To get this to work, the keyboard needs to be over the palette before it will accept focus away from the main work area, if you follow me.

OK, Tim. You can also right-click on the layer name and choose "Select by."

Yes, thank you Henry, that's always been my preference, although I'm always interested in new tricks!   :)

Many thanks for your inputs guys

Q1: As I thought  :( 
Q2: As shown for many answers on the forum, lateral thinking is essential when using TC  :)

Seems to me that it would have been faster to Group the three objects and 3D Subtract the Box, even if you had to explode that Group back to the component Groups and Blocks.
