Describes a plane. A plane is positioned in space with a coordinate system (a gp_Ax3 object), such that the plane is defined by the origin, "X Direction" and "Y Direction" of this coordinate system, which is the "local coordinate system" of the plane. The "main Direction" of the coordinate system is a vector normal to the plane. It gives the plane an implicit orientation such that the plane is said to be "direct", if the coordinate system is righthanded, or "indirect" in the other case. Note: when a gp_Pln plane is converted into a Geom_Plane plane, some implicit properties of its local coordinate system are used explicitly:  its origin defines the origin of the two parameters of the planar surface,  its implicit orientation is also that of the Geom_Plane. See Also gce_MakePln which provides functions for more complex plane constructions Geom_Plane which provides additional functions for constructing planes and works, in particular, with the parametric equations of planes
GPln.GPln  (  ) 
Creates a plane coincident with OXY plane of the reference coordinate system.
GPln.GPln  (  GAx3  theA3  ) 
The coordinate system of the plane is defined with the axis placement theA3. The "Direction" of theA3 defines the normal to the plane. The "Location" of theA3 defines the location (origin) of the plane. The "XDirection" and "YDirection" of theA3 define the "XAxis" and the "YAxis" of the plane used to parametrize the plane.
Creates a plane with the "Location" point <theP> and the normal direction <theV>.
GPln.GPln  (  double  theA, 
double  theB,  
double  theC,  
double  theD ) 
Creates a plane from its cartesian equation : theA * X + theB * Y + theC * Z + theD = 0.0
Raises ConstructionError if Sqrt (theA*theA + theB*theB + theC*theC) <= Resolution from gp.
GAx1 GPln.Axis  (  ) 
Returns the plane's normal Axis.
void GPln.Coefficients  (  double[]  theA, 
double[]  theB,  
double[]  theC,  
double[]  theD ) 
Returns the coefficients of the plane's cartesian equation : theA * X + theB * Y + theC * Z + theD = 0.
boolean GPln.Contains  (  GLin  theL, 
double  theLinearTolerance,  
double  theAngularTolerance ) 
Returns true if this plane contains the line theL. This means that  the distance between point P and this plane is less than or equal to LinearTolerance, or  line theL is normal to the "main Axis" of the local coordinate system of this plane, within the tolerance theAngularTolerance, and the distance between the origin of line theL and this plane is less than or equal to theLinearTolerance.
boolean GPln.Contains  (  GPnt  theP, 
double  theLinearTolerance ) 
Returns true if this plane contains the point theP. This means that  the distance between point theP and this plane is less than or equal to theLinearTolerance, or  line L is normal to the "main Axis" of the local coordinate system of this plane, within the tolerance AngularTolerance, and the distance between the origin of line L and this plane is less than or equal to theLinearTolerance.
boolean GPln.Direct  (  ) 
returns true if the Ax3 is right handed.
double GPln.Distance  (  GLin  theL  ) 
Computes the distance between <me> and the line <theL>.
double GPln.Distance  (  GPln  theOther  ) 
Computes the distance between two planes.
double GPln.Distance  (  GPnt  theP  ) 
Computes the distance between <me> and the point <theP>.
GPnt GPln.Location  (  ) 
Returns the plane's location (origin).
Performs the symmetrical transformation of a plane with respect to an axis placement which is the axis of the symmetry. The transformation is performed on the "Location" point, on the "XAxis" and the "YAxis". The resulting normal direction is the cross product between the "XDirection" and the "YDirection" after transformation if the initial plane was right handed, else it is the opposite.
Performs the symmetrical transformation of a plane with respect to an axis placement. The axis placement <A2> locates the plane of the symmetry. The transformation is performed on the "Location" point, on the "XAxis" and the "YAxis". The resulting normal direction is the cross product between the "XDirection" and the "YDirection" after transformation if the initial plane was right handed, else it is the opposite.
Performs the symmetrical transformation of a plane with respect to the point <theP> which is the center of the symmetry Warnings : The normal direction to the plane is not changed. The "XAxis" and the "YAxis" are reversed.
GAx3 GPln.Position  (  ) 
Returns the local coordinate system of the plane .
rotates a plane. theA1 is the axis of the rotation. theAng is the angular value of the rotation in radians.
void GPln.SetAxis  (  GAx1  theA1  ) 
Modifies this plane, by redefining its local coordinate system so that  its origin and "main Direction" become those of the axis theA1 (the "X Direction" and "Y Direction" are then recomputed). Raises ConstructionError if the theA1 is parallel to the "XAxis" of the plane.
void GPln.SetLocation  (  GPnt  theLoc  ) 
Changes the origin of the plane.
void GPln.SetPosition  (  GAx3  theA3  ) 
Changes the local coordinate system of the plane.
double GPln.SquareDistance  (  GLin  theL  )

Computes the square distance between two planes.
double GPln.SquareDistance  (  GPnt  theP  ) 
Computes the square distance between <me> and the point <theP>.
Transforms a plane with the transformation theT from class Trsf. The transformation is performed on the "Location" point, on the "XAxis" and the "YAxis". The resulting normal direction is the cross product between the "XDirection" and the "YDirection" after transformation.
Translates a plane from the point theP1 to the point theP2.
Translates a plane in the direction of the vector theV. The magnitude of the translation is the vector's magnitude.
void GPln.UReverse  (  ) 
Reverses the U parametrization of the plane reversing the XAxis.
void GPln.VReverse  (  ) 
Reverses the V parametrization of the plane reversing the YAxis.
