I wand to make a sharp triangle hole using subdivision surface. 1

I tried to add different position or combination of edge cuts inside this "hole" like this: 2

But this created strange looking things like: 3

I know that is something with triangle-shape polygons but I have no idea how to get rid of them.

What should I do?

  • $\begingroup$ You need supporting geometry not only inside cutout but also outside. Moreover this cutout is surrounded by ngons, which do not work well with subsurf. $\endgroup$ – Serge L May 16 '18 at 19:34

I think this could be a good start :

Another thing would be to do as much as you can from a bevel modifier with angle detection, weights and/or vertex groups. It has the advantage of being non-destructive and faster.
