I made mesh for deck of guitar. After, I had to make a hole in this mesh. Also I used Subdivision Surface Modifier. I created a circle to use "Knife Project". Made in the mesh a circle then deleted face to make a hole. As u can see, there are some triangles around this hole. If K remove "Subdivision surface", these triangles disappear.

  • your topology must be bad, please show the wireframe – moonboots Jul 16 '19 at 19:47
  • sorry your file makes my Blender crash, so someone else will help you ;) – moonboots Jul 16 '19 at 19:59
  • @moonboots should be 2.8... I was involved in another part https://blender.stackexchange.com/questions/145528/help-me-to-use-loop-cut-properly-blender-2-8?noredirect=1#comment248339_145528. This one is yours ; ) – lemon Jul 16 '19 at 20:10
  • And, @Kaznachei yes, a guitar for a beginner is hard (it is hard for anyone, in fact). – lemon Jul 16 '19 at 20:12
  • it crashes with my 2.8 ;) – moonboots Jul 16 '19 at 20:20
  • @moonboots, doesn't crash with 2.8RC (windows, downloaded today) here. But... no.. won't have time for this one. – lemon Jul 16 '19 at 20:26
  • Yes but i'm on mac and my 2.8 is several weeks old, i can't do anything unless he imports in 2.79, so maybe help Kaznachel if you have time ;) – moonboots Jul 16 '19 at 20:29
  • @moonboots, well... no sorry, won't have more time. Sorry Karnachei, but at some moment you'll need to fly by yourself. The problem is (ok we can help) but what you're asking is very specific (so a bit out of what can be done here, generally) – lemon Jul 16 '19 at 20:33

Ok, the problem you mentioned in the comments is because of these little straggler vertices that aren't connected to the mesh like the others.

stragglers

So to fix that you can start by deleting this ring of faces:

delete

Next, you create a new circle, place it where you want the hole, select the circle and the rim of the guitar created by the deleting of faces, hit ctrl-E, and select "bridge Edge loops".

And here is the result:

bridge

It's definitely not as pretty, but there doesn't seem to be any intersections or anything, and it does get the problem fixed. Hope that helps.
