I’m trying to get the hang of the very basics, and there’s something I don’t quite understand. I’ve tried searching for answers, but “edges” and “vertices” return a mountain of results, and answers to questions like “how to add new edges” end up telling me to do what I’m already doing.
If I have a basic square plane in Edit mode, and I bisect it by adding two vertices (subdiving two opposite edges) and connecting them with a new edge (selecting the new vertices and pressing F), it doesn’t actually seem to change the face at all. When I attempt to select one of what appear to be two faces in “face select,” I can still only select the entire original face. I can select the new edge with “edge select” and move/scale it around, but it behaves… oddly. Sometimes it comes off the plane or creates new un-editable geometry, or only appears to work at certain angles.
I’ve got a simple model I’m using to learn a bit (based on YanSculpts’s 2.8 tutorial video), but it’s a complete mess now because I can’t figure out how to fix this. All of the other methods of changing the model, like extruding, loop cuts, and insetting faces work perfectly. Simply adding vertices and connecting them seems to mangle everything pretty badly, though.
