I don't know if this is the best spot to post this question or not, but here it is:
I am working on a project that has a referenced revit file from an architect and I am placing some objects and for some reason I can see those objects on all three floors that are in the project.
Example: I draw a wall on the first floor plan and then I place a wall based tv mount and then I place the tv on the mount. I then go and hide the reference wall that I created so that the mount and the tv is all that is visible of my stuff. I finish with floor one and move on up to floor 2 and I can see everything that I drew on my first floor. Why is this happening?
