Along the Straight and Narrow
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 us 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, we divide the drawing commands into three groups:
Straight lines and objects composed of straight lines (covered in this chapter)
Curves (which we explain in Chapter 7)
Points (more in Chapter 7 if you’re wondering what the point of all this is)
After you’ve created some straight or curvy geometry, you’ll probably ...
