Introduction

Hard to use, impractical, difficult to learn, crude, slow. All these expressions have been used to describe 3D modeling in AutoCAD. At one time there was some validity in each of them, but as AutoCAD and the computers that run AutoCAD become more and more powerful and sophisticated, the reasons for not using the 3D features of AutoCAD become less and less valid. AutoCAD has good 3D modeling capabilities, most objects in the real world are 3D, and most designs should be done in 3D.
