Datasheet

In Figure 1.11, supplemental angles are determined from the interior angles and used
to calculate the resulting relative angle of the next line segment. As you draw, use the read-
out from polar tracking to determine the relative angle for the next segment. Sometimes it
will be reported to you as 299 instead of 61, for example, because it’s increasing in the
clockwise direction rather than the default counterclockwise direction.

Note that in this case, Increment Angle is set to one (1). This is a small angle, and it isn’t easy
to work with, but it can be used. If the angles you’re using are based on larger increments,
use them. It’s much easier to use an angle increment of 5, 15, or 45; but any increment can be
typed into the window, including values so small they are completely unusable as angles.
That’s one of the things I love about AutoCAD. It doesn’t restrict what you can do by overpro-
tecting you from the results of commands.
