Best way to cut a sphere?

[Anonymous]

I'm trying to cut this sphere so that it has a large opening at the top that gradually gets narrower. I've tried doing this by creating 3 separate sketches, and extruding/cutting into the sphere one at a time, but I end up with uneven faces as a result. Just wondering if there is a better approach to achieving this. Thanks!

Could you share your model by exporting it as a .f3d and attaching it to your next post ?

You have at least one red warning icon in your timeline that should be fixed.

I always ask myself - what manufacturing process will be used?

In this case I assume a revolving cutter.

Therefore I would do a half profile of the revolving tool and then Revolve-Cut.

I sketched a shape on the side plane and then extruded that shape through the sphere with the cut option; you do have quite a bit of control over the shape.

Here's a screencast showing a way to do it.
