Welcome to cfm-leapfrog’s documentation!

This module is designed to help create 3D models of complex fault systems, and works by projecting surface traces to depth. Fault surfaces can then be meshed and cut against each other either in Leapfrog Geo or entirely in Python, with no Leapfrog licence needed. For source code, please visit https://github.com/uc-eqgeo/cfm_leapfrog/.
