class GtoCConstraint from Plate
---Purpose: define a G1, G2 or G3 constraint on the Plate
--
uses
XY from gp,
XYZ from gp,
D1 from Plate,
D2 from Plate,
D3 from Plate,
PinpointConstraint from Plate
is
Create(ref : GtoCConstraint from Plate) returns GtoCConstraint;
Create(point2d : XY ; D1S , D1T : D1 ) returns GtoCConstraint;
-- G1 constraint:
-- D1S : first derivative of S, the surface we want to correct
-- D1T : first derivative of the reference surface
Create(point2d : XY ; D1S , D1T : D1;
nP : XYZ from gp ) returns GtoCConstraint;
-- G1 constraint:
-- D1S : first derivative of S, the surface we want to correct
-- D1T : first derivative of the reference surface
-- nP : normal vector to tge Plane in which we want the correction to occur
Create(point2d : XY from gp; D1S , D1T : D1 from Plate;
D2S, D2T : D2 from Plate) returns GtoCConstraint;

-- D3S : third derivative of S, the surface we want to correct
-- D3T : third derivative of the reference surface
Create(point2d : XY from gp; D1S , D1T : D1 from Plate;
D2S, D2T : D2 from Plate;
D3S, D3T : D3 from Plate;
