A 2D drawing view is a representation of a 3D CAD part or assembly that is placed on a drawing sheet. A drawing view represents the shape of the object when viewed from various standard directions, such as front, top, side, and so on.
Most designers and engineers already know that. What you may not know is how much more you can do with your drawings, with just a little bit of guidance.
