Noob Q: software to create the position of a dial knob

Hi guys,
I’ve been asking around but can’t find any answer.
I know there’s software to create a dial/rotary knob and its positions.
How do you guys do it?

Not sure I understand your question. Can you explain what you’re trying to do? Do you mean a physical rotary knob? If so, I’m not sure we’re the right community to be answering you!
