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.
The orientation of 0 depends on the angle you set in the Drawing Units dialog
box. The direction of snap (clockwise or counterclockwise) depends on the
units direction you specify when setting units of measurement.
You can turn polar tracking on and off temporarily by using an override key.
The direct distance entry method is not available while you are using the
temporary override key for polar tracking.
Specify Polar Distances (PolarSnap)
PolarSnap restricts cursor movement to increments of a polar distance you
specify. For example, if you specify a length of 4 units, the cursor snaps from
