I've been trying to figure out CADMEP myself at work, and one of the things I've been struggling with is, let say I want to move a section of pipe over to a square-round, I click on the white crosshair on the bottom of the pipe then go over to the sq-round and I can't get it to find the center of that part so I end up having to kind of guess. Or sometimes I will select a pipe or an elbow to move and can only get one pick point on the other side of the part. I have all the snaps on in 2D and 3D
