Loving Rhino 7 and the SubD revolution! Great for jewelry purposes. But…
There’s a function in RhinoGold that I love called CopyByGems. So for example you make a bunch of various sized diamonds on a curve or surface, and want to put a hole-cutter on each. CopyByGems takes a a cutter and orients it and can scale it to all those diamonds from a single origin diamond.
I guess one way to do this is by using blocks. Create a block out of one diamond and then scale that block to different sizes and positions. Then if you edit block to add that cutter it gets added to all diamonds. If you then explode your blocks you have your cutter in the correct position and size.
