Sample points on a surface

Hi,

I need to create a solidworks model from some surfaces which are imported from an optical design software.

To evaluate the accuracy of the surface import, I'd like to sample a dense grid of points on the imported surfaces and obtain a XYZ position table. So that I can check the accurcy back in the optical design software.

I have no idea how to do it. Can anyone help?

Thanks a lot.
