This statement is not accurate, you are three-dimensional graphics (as some books to the original two-dimensional mapping method with elevation and thickness of this three-dimensional mapping that two-dimensional semi-) or axonometric drawings drawing (CAD, there is a isometric drawing function)? 9 Y2 v & ~! \.P4 K '[is painting it is not two-dimensional semi-isometric map.painting Axonometric If coordinates input, then the angle of the three orthogonal directions are 30 (210) degrees, 150 (330) degrees, and 90 (270) degrees.If @ 100 <30.
