So I'm trying to find my way around ProBuilder in Unity and started by trying to create a simple house Scene. On doing this from research to create holes in walls for windows/doors you use Edge Loops and then delete the materials in between which is fine. However after doing this I have rearlised Im left with lots of edge lines and am not sure how to deaal with them as some are not miss shaped and when trying to edit small things its getting messy. Am curious for any tips round this or what I'm doign wrong. Thanks very much. P.S. As you can see the main problem is these diagnols which are uselss to me but get in the way for future editing. I tried reading on this and people mentioned on Merging faces or Connect vertices but on doing that I was still left with some random loop lines which I could not get rid of. Any help would be great, thanks for your time.
