I’m trying to make a side of a modeled butter fly knife open when it is anchored at one end so it acts like a swivel. Thank you for your time.
If you’re asking about animation tools, Rhino does not have any native key frame animation tools to make object move.
The default tools have sun study, fly-through, and rotation.
If I understand what you’re after, you’ll probably need Bongo.
Most schools with Rhino lab licenses also have Bongo.
Does that help?
