I downloaded the Versa Care MedSurge bed and mobile workstation by Cesar. I can not select them all even if I highlight the entire entity. However if i highlight all of my sketchup it selects it.

I too am having the same problem. I installed a medical monitor from the 3-D warehouse, however when I go to move it the screen itself is completely separate. I have tried to make the whole room a component to move and scale but it still hasn't solved the problem. I've tried deleting it but I still can't select the item at all to delete it.
