Hello,

I am trying to create a ring in Sketchup so that I can create different size finger holes easily. I am copying the design from a prototype I have in copper, but am struggling to create the hole (17mm dia) through the compound curves of the ring's design.

The ring also tapers towards the back (the hole end), but I thought I would deal with the hole issue first. I have tried intersecting a cylinder through the model, but that opens up gaps in the geometry, as shown in the attached.

Am I approaching it in the wrong way? Would I be better using a plugin? Any help most appreciated.
