I am working on some lighting layouts. I have 4 floors that are typical and the architect has only done a lighting layout for the one floor. I need to be able to see the layout so that I can place the lights at each level but I can't figure out how to do this. I copied the lights in a 3d cad file to each level and linked that into my project, I can see the layout just fine but it interferes with my project, I am unable to select the lights that I have already put in, it is as if the cad file has become a barrier. Can someone tell me what is the correct way to do this.

Thanks
