Range Variable Function

I am looking for a way to create a points file using a function that I can bring into a solid modeler that can be used to create a cam surface. As a simple example, for a circle, I would want an angle in the first column, an x coordinate R*sin(Theta) in the second column and a y coordinate R*cos(Theta) in the second column. I may want to add a fourth column with a function for the profile in the z direction. Thanks, Karl.
