So I am trying to make a building in Blender for my University Project. I have made the outside of the building and now I am trying to add windows with frames at the front. One side of my building has a window, which I created with no issues. Now I am trying to clone this on the other side of the building I am finding that the loop cut keeps skipping a face of my window for some reason, and I can't figure out why! I have a few screenshots (https://imgur.com/a/1HwDHmn) and hopefully, this shows what I mean. Any help would be appreciated.

Side note, this is my first ever time using Blender so I am not aware of many of the shortcuts etc.

EDIT: Here is my blend file: Removed, can be readded if needed. Don't want my work being flagged up when I upload it.

  • $\begingroup$ There are either zero-area faces (visible dot indicating face between other faces) and / or Ngons in the area where loopcut breaks. If selecting all and removing doubles doesn't help select those manually and delete faces $\endgroup$

  • $\begingroup$ .. and since your building is largely symmetrical, it might save you work, if the (-Y) side is OK, to temporarily keep a copy of the asymmetrical element on the roof, complete the seam at Y=0, V > rip it, delete the (+Y) side, and mirror the whole building left to right. $\endgroup$ Mar 14, 2019 at 14:50
  • $\begingroup$ Thanks for the advice, will try all these solutions, hopefully one works. $\endgroup$
