Lock An Angle For One Point (Angle) - Autodesk 057B1-41A111-1001 - AutoCAD LT 2010 User Manual

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
the first point specified to lengths of 0, 4, 8, 12, 16, and so on. As you move
your cursor, a tooltip indicates the nearest PolarSnap increment. To restrict
point entry to polar distances, both polar tracking and Snap mode (set to
PolarSnap) must be on. You can turn off all snapping and tracking temporarily
by using an override key.

Lock an Angle for One Point (Angle)

You can specify an angle override that locks the cursor for the next point
entered.
To specify an angle override, enter a left angle bracket (<) followed by an angle
whenever a command asks you to specify a point. The Command prompt
sequence below shows a 30-degree override entered during a LINE command.
Command: line
Specify first point: Specify a start point for the line
Specify next point or [Undo]: <30
