My very rudimentary rings feature my name subtracted from the band. Even though I know they would not print successfully, I thought I was clever to have gotten that far! I have to say when I uploaded my thoughts to the MOI forum I was politely given a very nice alternative that I could try...Flow!
What a great idea to raise the letters following the curve of the band. However to achieve this started me on a CAD journey I never thought I'd go on. Yes, I have been up late at night on the forum being guided in baby steps by some very patient experts.
Eventually I learnt to UnwrapCurve and use the Flow command as you can see from the screen shots below:
One baby step at a time...I am looking forward to the point when I can cast one of my CAD creations and get myself back into the workshop. Be warned, this is an addictive pastime when you have a project in mind!
