Preciseliness Is Next to CADliness

In This Chapter

  • Typing coordinates at the keyboard
  • Getting to know AutoCAD's 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 get a little tense when you assign properties directly to objects instead of ByLayer, wait until you see them lay into someone (I sincerely hope it's not you!) who doesn't use precision techniques when creating drawings in AutoCAD.
