For millennia, people have documented the design and construction of three-dimensional objects by drawing two-dimensional views of them. Most people have continued to use these “classical” methods in CAD drafting because the methods are well understood and work reasonably well. After all, if 2D drawing was good enough for guys like Leonardo da Vinci and Andrea Palladio, it should be good enough for you, right?

Nonetheless, the past decade (or so) has seen a trend toward creating 3D CAD models and letting the software generate the 2D views more or less automatically. This approach seems more logical, especially if the project documentation requires numerous complex views of the same object. Three-dimensional modeling is an absolute necessity when you want to create rendered views for presentation purposes.

And although AutoCAD 3D construction and visualization tools have improved dramatically over the years (trust us — you should ...
