I am trying to create a shape know as an epitrochoid in CATIA. I have a few possible approaches: 1) I have created a spread sheet that contains all the X and Y coordinates needed to create the shape (360 points). How could I use the Excel spread sheet to generate points that I could connect using a spline without have to manually type all the points in? 2) I also have the parametric equations that are used to generate the shape. How do use these to generate a curve. The second approach is the preferred. If it helps to know what the shape looks like please visit http://mathworld.wolfram.com/EpitrochoidEvolute.html

Look in the one-lin doc.

Search for:
Creating Elements From An External File

There is a sample Excel file containing macros used to create curves and surfaces.

I don't think there is a way to input a parametric eq'n into CATIA. If you find a way, tell me...

Also, you you could use the kinematics workbench to trace the
curve... use a point on a planet gear to trace the curve.

Regards

Andre
