> i have about 2000 stacked cubes that needed added to a csg....
Just a quick question: How did you create the 2000 cubes? If you used
the Duplicate Dialog here's a tip for the future

First create the CSG or Group that you want the cubes to be in. Then
create the first cube (the one you're going to copy). Add this cube to
the CSG/Group. Select the cube and position it as you need, then call
the Duplicate function. In the dialog, enable the "Attach To Same
Parent" checkbox. Then press OK to create the copies. They are
automatically add to the CSG/Group.

The problem with multiple selection is that the control is a tree
control, not a list control. So if you select an subobject, it is
moved inside the tree. It starts getting ugly when you have to make
sure that a parent is not selected along with a child, etc. 

An alternative could be to make it a listbox and to only display
top-level objects. It would be easy to allow multiple selection in
this listbox. Would that be useful?
