Sandbox
Terrain is important to many SketchUp modellers: Your building needs ground to stand on. But wait. SketchUp’s Sandbox tools — the tools you use to model terrain — can also create forms completely unrelated to terrain. How can terrain include all these other possibilities? The secret is in the hidden geometry. When you’re modelling terrain (or other shapes) with the Sandbox tools, you’re technically sculpting a special type of geometry called a TIN, or triangulated irregular network. That’s a fancy way of saying, “a group comprised of triangles.” Check out our Sandbox tutorial below!
