beginner here.

I'm currently modeling my wristwatch and I'm running into some issues making the holes in the strap. I attempted to use the boolean modifier with a cylinder to get the holes out, and while the holes came out great in edit mode, the object itself is looking messed up, probably due to the subsurf:

I've tried edge loops, making a crease, hell, even bevels and nothing is fixing it. Does anyone have an idea as to what could be done to get this working?

Thanks so much!

Using booleans for holes is an easy temptation, but often brings horrible results, due to horrible topology. I would try something simpler like this:

and then let subsurf make the rounding:

  • $\begingroup$ Thanks so much! Definitely won't be using the Boolean modifier for holes anymore, such a headache! $\endgroup$ Commented Mar 5, 2017 at 16:35
  • $\begingroup$ Note: in this case, since it was simple, I suggested to avoid booleans, but there are cases where you can't avoid them, or they can help immensely (see other answers like blender.stackexchange.com/questions/71947/… or blender.stackexchange.com/questions/64567/…). Booleans can create easily very complex holes shapes, but since good topology is always your friend, if you MUST use boolean holes, take some time to clean topology after (ie: retopology, a task that is also often needed after sculpting). $\endgroup$

I guess my solution is the same as m.ardito ..... enter image description here enter image description here enter image description here enter image description here enter image description here
