Preciseliness Is Next to CADliness
IN THIS CHAPTER
Typing coordinates at the keyboard
Getting to know the AutoCAD coordinate systems
Snapping to object features
Using other precision drawing and editing techniques
Drawing precision is vital to good CAD drafting practice, even more than for manual drafting. Accuracy, of course, is vital to both types of drafting. If you’re sketchy on the difference between accuracy and precision, look ahead to the “CAD precision versus accuracy” sidebar in this chapter. If you think CAD managers become tense when you assign properties directly to objects instead of ByLayer (see Chapter 9), wait until someone — I sincerely hope it’s not you — fails to use precision techniques when creating drawings in AutoCAD.
