Parameters

radius
Type: SystemSingle
The minimum distance from the line to the origin.
theta
Type: SystemSingle
The angle of the vector from the origin to the line.

Return Value

Type: Line
Returns a Line representing the specified line.
Exceptions
ExceptionCondition
ArgumentOutOfRangeExceptionThrown if radius is negative.
Remarks

radius is the minimum distance from the origin to the line, and theta is the counterclockwise rotation from the positive X axis to the vector through the origin and normal to the line.

This means that if theta is in [0,180), the point on the line closest to the origin is on the positive X or Y axes, or in quadrants I or II. Likewise, if theta is in [180,360), the point on the line closest to the origin is on the negative X or Y axes, or in quadrants III or IV.
