I’m very new to Sketchup but am loving it. I’m trying to make a jointed post and was following the directions in this video https://www.youtube.com/watch?v=hjiKuJ03DbI at 17:16 or so he pushes a smaller rectangle inward. I get to that same spot with my own version and it won’t let me push inward. It allows me to pull it out but when I try to push in, nothing happens. I uploaded my model and I think this is the link. https://3dwarehouse.sketchup.com/model.html?id=u9559fdcb-3305-4f43-9c0f-288f8ae4a6e5 Any help/input would be greatly appreciated!
