So I have used the boolean operation to create a spherical hole inside a cube and was wondering how I could correct the topology. The result of this was: edit mode of sphere

So I was wondering how I can edit the topology so I can use subsurface modifier or if it is better if I Use a different method to create the hole. If I should recreate it a different way than what would be a good way keeping in mind that this is from a cube.

Thanks!

  • The best way to have correct topology is to avoid booleans. Don't create problems that you have to spend time fixing later. Read https://blender.stackexchange.com/questions/105386/weird-problem-with-faces-black-lines and 8 ways to make holes – susu Jan 10 '21 at 02:26
  • a quick way to fix your geometry is to create a bevel all along the edges so that when you give your object a Subdivision Surface it won't mess the whole shape. – moonboots Jan 10 '21 at 06:08

First triangulate the model.

After that, add a subdivison modifier, with simple and one with Catmull-Clark selected. Then do loopcuts, where you want to have sharp edges. Slide the loopcuts till the edges, but not on them, just a little bit before. You have to play a little bit with the strengt of the modfiere.
