Making a Topographic/contour map of 3d model from Solidworks

Hi Guys,

I have a model I’ve made in Solidworks that I wish to make out of foam(using hot wire cutters), it is quite complex and so have landed on the idea that it would be best to somehow map the contours from a top down view slicing the model into sections of 10mm or so, convert the contour lines to a vector and laser cut some box board for guide templates.

I just am not sure how to take my model and map those contour lines, has anyone done this before or have feed back?

Much appreciated.
