I'm trying to create my first equation generate curve. It is a compound parabolic concentrator. Here's a picture with the equations and variables:

In the yellow box you can see the error message. I do not understand why the curve exceeds the maximum model size. Here's a screen capture from Mathcad that shows the dimensions:

I really don't see why an object 4.346 mm long and 2*2.546 mm in diameter is too big for SW. Any ideas?

Steve,

I didn't look at your equations, but if the radius of curvature of your curve gets larger than 500 m, then that could probably result in your error message. That would put the center of the radius more than 500 m from the origin, which is a no-no for SW.
