Clean boolean hole in sphere, with bevelled "entrances"

Hello everyone,

I want to make a cylinder boolen (or other form) into a sphere. But I want to have

  1. very clean edges and inside of the boolean hole
  2. for another version, I want to have a (large) bevel on the edges of the boolean holes

This is an example of the fail. I have tried alot but yet only found the manual way of merging vertices on the edges. Im looking for a fast workflow.

Greetings

It’s kinda hard to boolean things into spheres while mantaining a good topology, it requires a lot of planning to make sure the segments of the sphere and the vertices of the boolean object are alligned.

If you are ok with a destructive workflow, I recommend you use the Bevel after Boolean addon. The topology can get messy, but it’s easy to use and the shading result will be very good:

Try the Weighted Normals modifier and see if that helps.
