Polar Coordinates
You can input polar coordinates in any field that accepts point locations.
Specify the coordinate with the keyword polar, so an X coordinate is polarx, a Y coordinate is polary and so on.
Sets the angle to be read as degrees, so polarxd means that you are entering a polar coordinate for X with the angle of rotation specified in degrees. Omitting the d specifies the angle in radians.
In parentheses, set the length of the offset, the rotation angle (which can be negative) and optionally, a specific center point. Examples are available.
