Export Contours of Solids

Hello everyone;

I'm fairly new to Rhino/Grasshopper and I'm drawing there my architectural scale models. The models are assembled out of various solids of the thickness of the cardboard. I then export the contours of the solids for computer aided cutting of the 2mm cardboard. (I've added images that might clarify the process)

Is there a way that I can automate this process in grasshopper, so the contours of my solids are directly placed on the side of the model cplane?

Thanks a lot;

Max
