Welcome to topocad! This repo contains utilities for topography-based 3D modeling using CAD + python scripting tools. To get started, check out the code or the example notebook.
Here's an example of a 3D topo model of Boulder, Colorado. The three spatial axes are to-scale and based on the DEM from USGS. The model is designed to be printed at a footprint of approximately 100mm x 100mm with approximately 7 pixels per mm. The 10m DEM was coarsened by 3x to produce the model. The model took 6 minutes to create on an M1 Macbook Air.
