is
FirstPoint(myclass; ML: MLine) returns Integer;
---Purpose: Returns the first index of multipoints of the MLine.
LastPoint(myclass; ML: MLine) returns Integer;
---Purpose: Returns the last index of multipoints of the MLine.
NbP2d(myclass; ML: MLine) returns Integer;
---Purpose: Returns the number of 2d points of a MLine.
NbP3d(myclass; ML: MLine) returns Integer;
---Purpose: Returns the number of 3d points of a MLine.
Value(myclass; ML: MLine; MPointIndex: Integer; tabPt: out Array1OfPnt);
---Purpose: returns the 3d points of the multipoint <MPointIndex>
-- when only 3d points exist.
Value(myclass; ML: MLine; MPointIndex: Integer;
tabPt2d: out Array1OfPnt2d);
---Purpose: returns the 2d points of the multipoint <MPointIndex>
-- when only 2d points exist.

returns Boolean;
---Purpose: returns the 2d tangency points of the multipoint
-- <MPointIndex> only when 2d points exist.
Tangency(myclass; ML: MLine; MPointIndex: Integer;
