Object Grouping

It would be so helpful to be able to group items in my 3D drawings to move and/or adjust them.

Example, I built a model of a bookcase entertainment center. I would like to move one of the towers over, but I can’t because the features don’t move as a unit. I have to move it shelf by shelf or redraw it.

Similarily, I have a 3d shape standing in for a bubble hockey game in a basement but to move it around I have to move each component independently.
