Slicing a Sphere

497 Views, 12 Replies

I am trying to create a part that has a spherical feature. The spherical feature is "sliced" on the front and back to create a flat surface (see Compound Rest Handle Isometric image). Should I use workplanes to slice the sphere? What is an efficient process the slice the sphere. See Compound Rest Handle Front and Compound Rest Handle Back images and compare to the final result in the Compound Rest Handle Isometric image), Thanks.

The easiest way would have been to Revolve the profile as the very first feature before adding the handles.

You could slice that one side but another way would be to start a sketch on each plane and select Project Cut Edges (from pull-down) and then Extrude - Cut the resulting circles pointing away from the center.

Handle Sketch (assuming making as one part rather than multi-body solid).

Third Revolve (add rectangle to sketch and do this as two revolves - New Solid if needing multi-body for handle).

Unless you modeled it as a multibody part you may find spliting the front gives you results you do not like at all, as the handles will split too. You may in that case have to use an extrude to cut the sphere flat where you need it.

JD's method would work well, but revolve the handle as a seperate body as you will have to add the pin and pin hole to the sketch, which also means the spheres that hold the handles on will also have a flat spot on them for contact surfaces.
