7. Finally, enter C ↵ to close the box. This tells AutoCAD to draw a line from
the last point picked to the first point picked and, in effect, closes the box.
AutoCAD then automatically ends the LINE command (see Figure 3.17).

This method for laying out building lines by using Snap and Grid and the
Dynamic Input is useful if the dimensions all conform to a convenient rounded-
off number, such as the nearest six inches. The key advantage to this method over
just typing the relative coordinates, as you did with the box in Chapter 2, is
that you avoid having to enter the numbers. You should, however, assess whether
the layout you need to draw has characteristics that lend themselves to using
Grid, Snap, and Dynamic Input or whether typing the relative coordinates would
be more efficient. As you get more comfortable with AutoCAD, you'll see that this
sort of question comes up often: which way is the most efficient? This happy
dilemma is inevitable in an application with enough tools to give you many
strategic choices. In Chapters 4 and 5, “Developing Drawing Strategies: Parts 1
and 2,” you'll learn other techniques for drawing rectangles.
