# About Entering 2D Polar Coordinates

You can use absolute or relative polar coordinates (distance and angle) to locate
points when creating objects.

To use polar coordinates to specify a point, enter a distance and an angle separated
by an angle bracket (<).

By default, angles increase in the counterclockwise direction and decrease in the
clockwise direction. To specify a clockwise direction, enter a negative value for
the angle. For example, entering 1<315 locates the same point as entering 1<-45. You can change the angle conventions for the current drawing with the UNITS command. ### Absolute Polar Coordinates

Absolute polar coordinates are measured from the UCS origin (0,0), which is the intersection
of the X and Y axes. Use absolute polar coordinates when you know the precise distance and angle
coordinates of the point.

With dynamic input, you can specify absolute coordinates with the # prefix. If you enter coordinates on the command line instead of in the tooltip, the
# prefix is not used. For example, entering #3<45 specifies a point 3 units from the origin at an angle of 45 degrees from the X axis.

The following example shows two lines drawn with absolute polar coordinates using
the default angle direction setting. Enter the following in the tooltip:

Command: line

From point: #0,0

To point: #4<120

To point: #5<30 ### Relative Polar Coordinates

Relative coordinates are based on the last point entered. Use relative coordinates
when you know the location of a point in relation to the previous point.

To specify relative coordinates, precede the coordinate values with an @ sign. For
example, entering @1<45 specifies a point at a distance of 1 unit from the last point specified at an angle
of 45 degrees from the X axis.

The following example shows two lines drawn with relative polar coordinates. In each
illustration, the line begins at the location labeled as the previous point.

Command: line

From point: @3<45
