Developed for the conceptual stages of design, SketchUp is a powerful yet easy-to-learn 3D modeling software tool that combines a simple, yet robust tool-set with an intelligent drawing system that streamlines and simplifies 3D design.

Edges and Faces: That's all there is to it

Every SketchUp model is made up of just two things: edges and faces. Edges are straight lines, and faces are the 2D shapes that are created when several edges form a flat loop. For example, a rectangular face is bound by four edges that are connected together at right angles. To build models in SketchUp, you draw edges and faces using a few simple tools that you can learn in a small amount of time. It's as simple as that. Learn more.
