Snaps question

Hello, I’m trying to make an indoor level and I’ve made some wall segments in 3ds max.Everything works fine, but I have one problem.I want to be able to snap my wall segments so that there isn’t a hole between them and yet they aren’t clipping into each other,but I cant find how can I do that in unity.Please help me!

There is an easy way to do this if the wall segments have colliders. Just hold down the command key (or the control key on Windows) and drag the object by the centre of its transform widget. The object will move and snap to the intersection of other objects with colliders.

Thanks that helped a lot!
