NOTE Ortho mode and polar tracking cannot be on at the same time. Turning
on Ortho turns off polar tracking.

Quick Reference
ORTHO
Constrains cursor movement to the horizontal or vertical direction.
ORTHOMODE
Constrains cursor movement to the perpendicular.
TEMPOVERRIDES
Turns temporary override keys on and off.
Use Polar Tracking and PolarSnap
Polar tracking restricts cursor movement to specified angles. PolarSnap restricts
cursor movement to specified increments along a polar angle.
When you are creating or modifying objects, you can use polar tracking to
display temporary alignment paths defined by the polar angles you specify.
In 3D views, polar tracking additionally provides an alignment path in the
up and down directions. In that case, the tooltip displays a +Z or -Z for the
angle.
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.
