IN THIS CHAPTER

Drawing linear things with the AutoCAD drawing commands

Lining up for lines and polylines

Closing up with rectangles and polygons

As you may recall from your crayon-and-coloring-book days, drawing is *fun.* Computer-aided drafting (CAD) imposes a little more discipline, but drawing with AutoCAD is still fun. Trust me on this one. In computer-aided drafting, you usually start by drawing geometry from basic shapes — lines, circles, and rectangles — to represent the real-world object that you’re documenting.

For descriptive purposes, I divide the drawing commands into three groups:

**Straight lines**and objects composed of straight lines, covered in this chapter**Curves,**which I explain in Chapter 7**Points,**explained in Chapter 7 as well if you’re wondering what the point of all this is

After you’ve created some straight or curvy geometry, you’ll probably need to add dimensions, text, and hatching, but those elements come later (in Part 3). Or you may want to use that geometry as the basis for some cool 3D modeling. I introduce you to that topic in Part 5. Your first task is to get the geometry right; then you can worry about labeling elements.
