Does anyone know how to increase the number of spokes in a cylinder in Silo? (so it's more rounded)

• There are all sorts of tutorials out there, but a lot of this kind of basic is skipped.  I can't figure it out.

Beyond this - does anyone know how to take a cylinder and make it into a gear in Silo?

• In 3DSMax you simply use a star, and adjust the teeth, and inner and outer radius

• In Modo you simply extrude the edges, then adjust their base width via the box on the left.

Can't figure out (nor find) how to do this in Silo.  Thanks!
