| IsPlanar(Plane) | Checks whether this curve is planar. If the curve is a line, this function returns an arbitrary plane that contains the line. The plane parameter contains meaningful data only if this function returns a value of true. | |
| IsPlanar(Plane, Tolerance) | Checks whether this curve is planar within a specified tolerance. If the curve is a line, this function returns an arbitrary plane that contains the line. The plane parameter contains meaningful data only if this function returns a value of true. |
