## Constructor & Destructor Documentation

 GeomPlate_PointConstraint::GeomPlate_PointConstraint ( const gp_Pnt & Pt, const Standard_Integer Order, const Standard_Real TolDist = `0.0001` )

Constructs a point constraint object defined by Pt, a 3D point Order gives the order of constraint, one of:

• -1 i.e. none, or 0 i.e.G0 when assigned to Pt
• -1 i.e. none, 0 i.e. G0, 1 i.e. G1, 2 i.e. G2 when assigned to U, V and Surf. In this constructor, only TolDist is given. Distance tolerance represents the greatest distance allowed between the constraint and the target surface. Angular tolerance represents the largest angle allowed between the constraint and the target surface. Curvature tolerance represents the greatest difference in curvature allowed between the constraint and the target surface. Raises ConstructionError if Order is not 0 or -1
 GeomPlate_PointConstraint::GeomPlate_PointConstraint ( const Standard_Real U, const Standard_Real V, const Handle< Geom_Surface > & Surf, const Standard_Integer Order, const Standard_Real TolDist = `0.0001`, const Standard_Real TolAng = `0.01`, const Standard_Real TolCurv = `0.1` )

Constructs a point constraint object defined by the intersection point of U and V on the surface Surf. Order gives the order of constraint, one of:

• -1 i.e. none, or 0 i.e.G0 when assigned to Pt
• -1 i.e. none, 0 i.e. G0, 1 i.e. G1, 2 i.e. G2 when assigned to U, V and Surf. In this constructor the surface to be generated must respect several tolerance values only:
• the distance tolerance TolDist
• the angular tolerance TolAng
• the curvature tolerance, TolCurv. Distance tolerance represents the greatest distance allowed between the constraint and the target surface. Angular tolerance represents the largest angle allowed between the constraint and the target surface. Curvature tolerance represents the greatest difference in curvature allowed between the constraint and the target surface.Creates a punctual constraint.
