Mountain Goat - Laser Cut Contour Site Model Tool
(by Zachary Ebbers)

It started with a laser cut site model for Capstone Studio. I thought grasshopper could help with dimensions and seeing what scale I need to laser cut at. 

Turns out Grasshopper can do a lot more.

This idea evolved into a tool. A tool that can help create laser cut contour models.

There is no guarantee that mountain goats will be traversing your finished site model.


This tool takes 1:1 contour lines from a software like CADmapper and creates curves for a laser cut file. The tool uses the stepped contour method to save materials (only uses 2-6 sheets of material instead of 30+). The output curves can then be placed in a shop/lab template (for instance SCADLab or your university’ lab).

Must have missing plugg-ins resolved. If prompted, download these plugins: Pufferfish, Tree Sloth, Peacock, and Wombat.


- Calculates total dimensions of physical model

- Engraves buildings, roads, and paths into contour steps.

- List of scale and scale factors (1/16”, 1/18”, 1:192, 1:64 etc)

- Number and tag material sheets and contours

- Input your material dimensions and thickness and see the largest scale you can fit! 

- Automatically puts baked geometry on a colored layer. By default the colors match SCADLab standards. 

Future Updates:

- Side Profiles Creation
- Subdividing larger sites into laser cut sections. For models larger than laser cutter allowable bounds.
