In mechanical drawing, it is not practical
to simply draw by eye, even for simple shapes. For example, to draw a rounded rectangle you can try
a dozen times to do it by eye - or you can combine three commands and be done in
seconds. This section covers these commands and shows how to draw basic
2D shapes which are the foundation for making
3D
shapes.
"A friend of mine said that he has tried various CAD programs over the years and none has been sufficiently easy for him the master with the exception of the software from emachineshop.com. He swears by it, and says that for the first time he finds himself going directly to the drawing software rather than pencil and paper."
