SketchUp was developed for the conceptual stages of the project, with a 3D structure very easy to learn. In an analogy, SketchUp can be considered "the pencil of digital design." It combines a series of tools that simplify your life.
Dream, Design and Communicate in 3D!
Why SketchUp is different? It contains a unique interface that allows 3D forms to be created, viewed and modified. The core of its simplicity is that you simply draw the edges of 3D models, as you probably would using pencil and paper.
SketchUp is great, extrapolating their design intent and automatically determines the nature of the lines, fill shapes to create 3D geometry.
