Explode or ungroup Sketchup 3D symbols?

Hello. Is it possible to explode or ungroup Sketchup 3D symbols in order to modify the individual pieces? For instance, I imported a room from Sketchup and want to select and/or alter particular individual pieces in the room, with the final goal of incorporating these items into my design..

I searched the threads but didn't find anything. Maybe I am using the wrong terminology.

Thank you. -- Anca

OH! I would also like to be able to edit BHG items as well. For instance, I'd like to exit the fireplace, making the inside a different material from the mantle, etc...

Download Google's free version of SketchUp, it'll allow you to make changes. http://sketchup.google.com/download/

I opened a fish tank that I didn't like the look of the water or the fish and removed them in SketchUp before importing the symbol into Home Designer.

OK. That works. As usual, thanks Kat. -- Anca
