Hi Tony, You can change the 3D objects to other tab. Suppose you're working on the floor tab. Click on the tub, for example--> Edit--> Move to plan--> Plumbing (for example) Again in the Floor tab, (or electrical, etc), you will see a small black arrow at the right of the name. By clicking the small arrow you have the option of viewing or hiding other tabs. Just check the names of the tabs you wish to show. (see the image attached). In your case, if you uncheck the plumbing tab, the tub will not be visible, and you can easily select the window Hope this helps Patricia
