To help me learn Rhino 3d I have been making a few youtube videos to show some basic operations. These can be found at www.wockit.co.uk.
I just noticed these (better late than never!). These are topical for jewelry designers getting familiar with Rhino.
As these have moved down in your tumblr feed, I’m reposting for other’s convenience:
