Modeling a yoyo in rhino 4.0

[Runnen]

I'm new to the program and am wondering how I would go about modeling something as simple as a yoyo. I've heard all I have to do is draw---with the line tool---half of the yoyo and then project that around an axis. If you would agree with this then could you explain how I would go about doing that? I would prefer doing it this way because I could make the shape of the yoyo more complex without having to do extra unnecessary work. If it is prudent that I go about this a different way then it would greatly help me if you could explain how and why it should be done this way.

 

All help is greatly appreciated!

 

Thanks you for reading.

EDIT: Sorry I had not noticed this was the wrong section. Could a moderator please move this to the correct area?

Welcome to the forum Runnen.

I have moved your question to the Rhino section.

 

I don't use Rhino, but most 3D programs work on basically the same principles and the same techniques apply. To create something like a yo-yo, you would draw half of the profile and then Revolve it 360 degrees around its center point. You can create very complex objects with this very simple technique.

Sorry for sort of resurrecting this post but I am completely new to the program and would like it if someone could give me a step by step way on how to do this?

If you google Rhino+Tutorials you find a lot.

Here is one example:

make one curve and revolve around a center axis.
