Name	Type	Purpose
East	REAL Get/Set	The East component
North	REAL Get/Set	The North component
Up	REAL Get/Set	The Up component
Origin	DBREF Get/Set	The DB element that is the origin

Name	Result	Purpose
Position(STRING )	POSITION	Creates a POSITION at the coordinates given in STRING.
Position(STRING, FORMAT)	POSITION	Creates a POSITION at the coordinates given in STRING, with the specified FORMAT.
Component(DIRECTION)	REAL	Magnitude of component in specified DIRECTION.
EQ(POSITION)	BOOLEAN	TRUE if POSITIONS are the same.
LT(POSITION)	BOOLEAN	TRUE if POSITION is less than argument.
String(FORMAT)	STRING	Convert POSITION to a STRING.
WRT(DBREF)	POSITION	Convert to a new POSITION with respect to given DB element.
Angle (POSITION, POSITION)	REAL	Returns the angle between the passed two points about the position object.
ArcCentre(POSITION, POSITION, POSITION, DIRECTION, REAL )	ARC	Returns an arc using arc centre technique. The direction is the ‘normal viewing’ direction.
ArcCentre(POSITION, POSITION, POSITION, DIRECTION, REAL)	ARC	Returns an arc using arc centre technique. The direction is the ‘normal viewing’ direction. Please see diagram for full explanation.

Name	Result	Purpose
ArcFillet( POSITION, POSITION, DIRECTION, REAL )	ARC	Returns an arc using arc centre technique. The direction is the ‘normal viewing’ direction. Please see diagram for full explanation.
ArcRadius( POSITION, POSITION, DIRECTION, REAL, BOOLEAN )	ARC	Returns an arc using arc radius technique. The direction is the ‘normal viewing’ direction. The boolean selects the minor (FALSE) or major(TRUE) arc. Please see diagram for full explanation.

Name	Result	Purpose
ArcThru( POSITION, POSITION, DIRECTION )	ARC	Returns an arc using arc through 3 points technique. The direction is the ‘normal viewing’ direction. Please see diagram for full explanation.

Name	Result	Purpose
ArcThru( POSITION, POSITION, DIRECTION, REAL )	ARC	Returns an arc using arc through 3 points and radius technique. The direction is the ‘normal viewing’ direction. Please see diagram for full explanation.

Name	Result	Purpose
Arc3Lines( LINE, LINE, LINE, DIRECTION )	ARC	Returns a circle through the 3 line tangent points. The 'this' position refers to the zone in which the circle lies.
Direction(POSITION)	BOOLEAN	Returns the direction between the position and the supplied position
Distance(ARC)	REAL	Returns the distance between the position and the nearest point on the arc line of the passed arc definition
MidPoint(POSITION)	POSITION	Returns the mid point between the two positions
Near(POSITION, REAL)	BOOLEAN	Returns true if the passed position is within the passed distance from the position object
Offset(DIRECTION, REAL)	POSITION	Returns a position offset by the supplied length in the supplied direction
Plane(POSITION, POSITION)	PLANE	Returns a plane in which each of the supplied points lie.
Distance(LINE)	REAL	Returns the distance between the position and the nearest point on the passed infinite line definition
Distance(PLANE)	REAL	Returns the distance between the position and the nearest point on the passed plane definition
Distance(POSITION)	REAL	Returns the distance between the two positions
Line(POSITION)	LINE	Returns a line between the two positions, starting at the position object
MidPoint(POSITION)	POSITION	Returns the mid point between the two positions
Near(POSITION, REAL)	BOOLEAN	Returns true if the passed position is within the passed distance from the position object
Offset(DIRECTION, REAL)	POSITION	Returns a position offset by the supplied length in the supplied direction
Plane(POSITION, POSITION)	PLANE	Returns a plane in which each of the supplied points lie.
