![]() ![]() This year marks the 10th anniversary of the Earth Educators' Rendezvous (EER), and time for us to reflect on what we've learned over the past ten years about running a conference and the evolving needs of the geoscience education community. There are extensive tutorials available from the SketchUp website's help center.Ĭreating 3D Geological Maps using Sketch Up (PowerPoint 1.1MB Feb11 08), a presentation from the 2008 workshop on Teaching with New Geoscience Tools.Įxciting changes coming to the Earth Educators' Rendezvous Once the structural model is complete, I add the terrain model and intersect it with the structure. It is best to keep the cross section simple and use kink geometry to minimize the number of nodes. To make a 3D model I create sequential cross sections using 2DMove, export them as dxf (Autocad format) and in SketchUp I connect the layers in adjacent cross sections to form surfaces. There is a free version of program available for downloading, or you can buy SketchUp Pro for about $400. It helps them understand how the contacts can be extrapolated across slopes and over ridges. Best suited to the lab, ideally after exposure to the real thing, or in preparation for it.Īfter field-mapping, drawing a cross section, and attempting to draw a geological map, I show the students the 3D model. It can be used at any level for show and tell. There is a huge repository of 3D models of all kinds of things at the SketchUp 3D warehouse. I have used this program to help students visualize the interaction between geological structure and topography, to illustrate map patterns of refolded folds, and thrust belt map patterns (klippe and windows). However, most geological models lie below the surface, so this is not the best way to display them. ![]() It is has a link to Google Earth which allows you to bring a terrane model from Google Earth and to export your 3D models to it. SketchUp ( This site may be offline.) is a 3D drawing tool designed primarily for architectural applications, however with a little bit of ingenuity it can be used to make models of 3D geological structures.
