Seems like it’s question week, Anyway, I have to workflows to get this shape.
create a truncated cone, boolean it out of a cylinder and then boolean the result out of the target cylinder. This gives me a nice center on top.
Chamfer the cylinder
When using the second approach the result does not have a center on the top, which shape-wise would be logical, if a circular shape with a center is chamfered, why would the result not have a center as well?
