Bug in Rhino double shelled solid?

Hi All,

Need a bit of help to unravel this mystery. Seems like a bit of bug to me

Rhino is giving an unexpected result when revolving a double shelled shape:

I would expect revolving this shape would create a solid with a void inside instead instead of solid.
Once there is an opening in the revolve the shape is expected.

is this a Bug? Any workarounds?

I tried building it from two solids and boolean it together but it still creates a ‘solid’ solid.
Boolean difference with the inner and outer shape does not work either

I tried something similar in Solidworks. This works well:

yet when you import this in rhino it is imported as two solids:

Thanks!

It’s not a bug. It’s a limitation of Rhino.

Select both parts and run the command _NonManifoldMerge

amazing! thanks for your fast reply Martin
