Enter 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 (<).

*1<315* locates the same point as entering
*1<-45*. You can change the angle
conventions for the current drawing with UNITS.

*X* and *Y* axes. Use absolute polar coordinates when you know
the precise distance and angle coordinates of the point.

*#* 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. For
more information about Dynamic Input, see
Use Dynamic Input.

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 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.

*@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*

To point: *@5<285*
