How to model Cross Belt drive in Catia

Hello, you can do this using the Freestyle module of CATIA.
I don't show you how to create a cross belt drive but a technique to draw a lot of similar objects.

  1. Step 1:

    First you have to create a 3d curve.

  2. Step 2:

    You create a another 3d curve which intersect the first created 3D curve.
    Right-click on a point to constrain him

  3. Step 3:

    You can add a third 3D curve.

  4. Step 4:

    With the generative shape design module, creat a multi-section surface.
    You can add another sections if you want.

  5. Step 5:

    The first created 3D curve can be a circle, and the another can be lines etc....
    I use 3D Curve because these kind of curves are very flexibles. You can constrain each points of the curve.
    With this technique you can draw a lot of various forms.
