Hi, I am currently constructing a Building and want to make a 3D section cut later on. Is there any way I can find out if I which Object collide with each other, without going through all of them. There are about 4000 Extrusions and I am looking for a fast way of doing this. Thank you for your help.

Hi -

You should be able to select them all and run Intersect. I suppose that, for many object, this might take some time.
