To enter a polar coordinate, enter a distance and an angle, separated by an angle bracket (<). For example, to specify a point that is at a distance of 1 unit from the previous point and at an angle of 45 degrees, enter @1<-45.
By default, angles increase in the counterclockwise and decrease in the clockwise direction. To move clockwise, enter a negative value for the angle. For example, entering 1<315 is the same as entering 1<45. You can change the angle direction for the current drawing with DDUNITS or the ANGDIR system variable. Also, ANGBASE sets the direction of the 0 angle.
Polar coordinates are either absolute (measured from origin) or relative to the previous point. To specify a relative coordinate, precede the coordinate with an @ symbol.
The following example shows a line drawn with polar coordinates using the default angle direction setting. For more information on angle direction conventions, see Starting and Saving a Drawing.
Command: Enter line
From point: Enter 0,0
To point: Enter 4<120
To point: Enter 5<30
The following example shows a line drawn with relative polar coordinates.
To point: Enter @3<45
To point: Enter @5<285
To point: Press ENTER
