How SketchUp works
• Clever user interface for extruding 2D objects
• Great for architectural stuff (cubes, cylinders, pyramids, etc)
• It is based on edges and planes, not volumes
• Not so great for free-form objects, but….

How to Make a 3D Geological Model
1. Make sequential cross sections with kinky geometry2. Interpret both above and below the ground3. Export to SketchUp as .dxf together with 2D map4. Put each geological unit in a SketchUp layer5. Hide all layers but one6. Join the cross sections to form a surface7. Repeat for all your units8. Import the DEM9. Intersect the 3D model and the DEM10. Optional: add colors, textures, etc.
