Extracting position and slope data from a 3d CAD model

Firstly, I am a complete beginner at Rhino. What I have is a windscreen shape in 3d CAD format. Is it possible to define a rectangular grid of points and extract x,y, slope data at each point? I need this data to drive some motors for a measurement project.

Hello - it is possible, but you’ll need a script or Grasshopper. Please post an example file.
