(Ctrl/Option ensures that you will leave a flat face on the back of the frame, and not make a hollow shell.) To pull out the window frame, activate Push/Pull and press Ctrl (Option on the Mac) and pull out the frame face. Make it small enough so that several rows and columns of windows can fit in the wall. In the lower-left corner of the front wall, draw the basic window shape by using a rectangle and an arc, erasing the dividing line between them. Paint the front and back faces, if you want. Keep in mind, however, that after you start a new Move or Rotate action, or activate a new tool, you can no longer adjust the spacing, angles, and so on.ĭraw a rectangle and use Push/Pull to pull it up.Įrase a side wall so that you can see inside (right-click on the face and choose Erase). For both kinds of copying, you can make these adjustments as many times as needed while the tool is still active. For linear copies, you can adjust the spacing and number of copies, and for rotated copies, you can adjust the angle between copies and the number of copies. ![]() For both tools, when you press the Ctrl/Option key, you will make copies. (Plus it never hurts to review some basics.)Īs you probably know, the Move tool is used to move objects, and the Rotate tool is used to rotate objects. Even some experienced users don’t know all there is about how to copy, which is a fundamental and important concept. If you’ve done any basic work with SketchUp, you might already be familiar with the concepts in this chapter. 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.This chapter covers the various ways you can make linear and rotated copies by using the Move and Rotate tools. 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 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.
