I am very new to blender and I am currently attempting to model a lightsaber.
So far it has been good, but I have hit a snag with the boolean modifier. I have multiple spheres which I need to difference from the main object and I am getting weird results. I have made a 40 seconds screen recording of the problem I encounter as it will be better than me trying to explain as I don’t yet possess the necessary knowledge for 3D modelling terms.
Please let me know what you think may be wrong and what I should do to fix it.
The resulting structure is not suitable for subdivision. You’re using high resolution spheres to make the boolean and Blender uses concave n-gon faces to make the connection between flat surface and the cut sphere halves, which is wrong in multiple ways. It might give a better result without applying the modifier because then it does the boolean after subdivision surface puts more geometry on there, but still, boolean operations aren’t high on the list as a modeling tool.
How to model them is similar to modeling holes for subdivision surfaces, except that yours will be filled.

The workflow in the example might not be suitable for you, and since the detail is so small in yours, it would only need 6 or 8 vertices around each. Subdivision surface puts more geometry on there. Could do with 4 if you don’t mind them being slightly distorted.
