I just started using SketchUp today, so sorry if this is a stupid question. So far I’m very impressed with the tool, but one annoyance is that I seem to keep accidentally creating extra diagonal edges on my walls. It seems to happen when I use push/pull to cut out windows and doors. See this screenshot:
If I just try to delete the edges, chunks of the wall disappear:
Anyone know why this is happening, how I can fix it for these walls, and perhaps how to prevent it in the future?
I’ve found I can remove/hide some (but not all) of these unwanted edges with the “soften/smooth edges” tool, but I have no idea why this works, and whether it is in fact just masking something I’m doing wrong.
