I recently made several updates to my game to make placing windows in walls easier. there were several complaints during the demo about how complicated it could be, and they were right.

This comes with other updates to make placement easier, previously, these objects would simply "stand" on the walls when you moved them there. With windows needed something extra special in case the surface is wall, needed to center it and change the size of the window, but also make a hole, I am not totally happy about it, but I am using CSG for the holes, my game do not require complex meshes specially for walls, so it kind of works with some face normals issues that I need to fix later.
