In this video, we will begin to build surfaces representing the different units within the geological model.

Please note: In late 2020, Leapfrog Works received a significant update to its user interface. While the current version of Leapfrog looks quite different from the version used to record this video, most of this content is still valid as the layout, location of functions, and workflows remain largely the same. For more information about the latest new features, please see the Leapfrog Works product page (
