There are five core concepts that make SketchUp unique. It's best to understand them so you can leverage these behaviors in your favor.
SketchUp is a surface modeler that is unlike most three-dimensional 3D modeling programs. Everything in SketchUp is composed of edges and surfaces-they're the basic building blocks used in SketchUp. A surface cannot exist without a closed loop of coplanar edges, and the simplest surface possible is a triangle.
There are no true, perfect vector curves, arcs, or circles in SketchUp. However, you can still represent circles and curves with a series of small edges. More segments will produce a smoother curve and also more geometry, resulting in a heavier model. Notice that it's hard to tell the difference between 48 segments and 96 segments.
SketchUp geometry has a tendency to stick together, a concept known as the "stickiness of geometry." Adjoining surfaces stick together and move with one another. Connected endpoints will move with each other and stretch their corresponding lines Even though this can be frustrating at first, once you learn to control the stickiness with containers, you will realize how much it speeds up the modeling process. Later in this course you will learn how to control this phenomenon with groups and components.
Geometry does not stack in SketchUp. Only one edge or surface can exist between the same series of points. Even when multiple edges are drawn on top of each other, the edges simply combine into one. When an edge that intersects or overlaps an existing edge is drawn, the existing edge will be broken into two pieces.
