#### Return Value

Type: Line

Returns a Line representing the specified line.

- 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.

Returns a Line representing the specified line.

Exceptions

Exception | Condition |
---|---|

ArgumentOutOfRangeException | Thrown 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.
