| Returns TRUE if where lies on the unbounded line. | ||
| Returns TRUE if where lies on the line, bounded indicates if the point is also checked to be on the bounded line segment. | ||
| Returns TRUE if where, when projected onto the line, lies within the bounded line. | 
| Returns the intersection line of plane on the line definition. | ||
| Returns the intersection points of arc on the line definition. | ||
| Figure 2:2.	 | 
| Returns a plane object, using the StartPosition and Direction of line object | ||
| Returns a POINTVECTOR object, using the StartPosition and Direction of line object | 
| Returns a new line, maintaining the original StartPosition and direction, with an EndPosition to match length. | ||
| Returns a new line, maintaining the original EndPosition and direction, with a StartPosition to match length. | ||
| Returns a new line object with the same StartPosition and the same relative EndPosition (Length) of the original line, but the direction is from the start position to position. | ||
| Returns a new LINE, where the StartPosition has been extended in the opposite direction of line by distance. | ||
| Returns a new LINE, where the EndPosition has been extended in the direction of the line by distance. | 
| Returns a LINE definition normalised onto plane. See picture. | ||
| Returns a parallel to the line definition of the line object, through position. All other members are copied. See picture. | ||
| Returns a parallel line to the LINE object, offset by offset from the original in the given direction. See picture. | 
| Returns the overlapping line of two parallel lines. All positions are return projected onto the original object. See picture. | ||
| Returns the union of LINE and other. The two are parallel lines, all positions are return projected onto the original object. See picture. |
