I have an issue that I can't seem to work out?
I made a very quick object using the revolve tool & then used rail sweep with a square profile 2mm x 2mm to be able to 3D Subtract the rail sweep from the object leaving a small V Notch groove on the outer surface.
When I 3D Subtract it removes a whole section of the object & not just the V Notch as required.
I tried changing the object & the rail sweep profile to Solids & also to Surfaces to see if it would work, but not so.
Not really sure what to do next?
I have attached a couple of screenshots to show the issue.
