Polar angles are relative to the orientation of the current user coordinate
system (UCS) and the setting for the base angle convention in a drawing. The
angle base direction is set in the Drawing Units dialog box (UNITS).
Use PolarSnap
to snap to specified distances along the alignment path. For
example, in the following illustration you draw a two-unit line from point 1
to point 2, and then draw a two-unit line to point 3 at a 45-degree angle to
the line. If you turn on the 45-degree polar angle increment, an alignment
path and tooltip are displayed when your cursor crosses the 0 or 45-degree
angle. The alignment path and tooltip disappear when you move the cursor
away from the angle.
As you move your cursor, alignment paths and tooltips are displayed when
you move the cursor near polar angles. The default angle measurement is 90
degrees. Use the alignment path and tooltip to draw your object. You can use
polar tracking with Intersection and Apparent Intersection object snaps to
find where a polar alignment path intersects another object.
NOTE
Ortho mode and polar tracking cannot be on at the same time. Turning on
polar tracking turns off Ortho mode. Similarly, PolarSnap and grid snap cannot
be on at the same time. Turning on PolarSnap turns off grid snap.
Specify Polar Angles (Polar Tracking)
You can use polar tracking to track along polar angle increments of 90, 60,
45, 30, 22.5, 18, 15, 10, and 5 degrees, or you can specify other angles. The
following illustration shows the alignment paths displayed as you move your
cursor 90 degrees with the polar angle increment set to 30 degrees.
