AUTOCAD [AUTOCAD REFERENCE MANUAL] BY AUTODESK, INC. (PUBLICATION 100752-01)

The AutoCAD design package (ACAD) is a powerful drawing tool. It follows your instruction and quickly produces the exact drawing you wnt. AutoCAD features let you correct drawing errors easily and make revisions without redoing the entire drawing. It produces clean, precise final drawings. AutoCAD works for you; it doesn't put anything into your drawing on its own. A completed AutoCAD drawing looks identical to the same drawing carefully prepared by hand. In fact, when used with the proper equipment, AutoCAD can greatly improve accuracy. Your drawing is created exactly as you specify, with every element appearing just where you want it. Sample drawings between chapters and before Appendix A demonstrate the many ways of using AutoCAD. This chapter introduces important concepts and terminology that you must understand to use AutoCAD effectively.
