Detailed Description
This class implements the following algorithms used to create a Plane from gp.
- Create a Pln parallel to another and passing through a point.
- Create a Pln passing through 3 points.
- Create a Pln by its normal. Defines a non-persistent plane. The plane is located in 3D space with an axis placement two axis. It is the local coordinate system of the plane.
The "Location" point and the main direction of this axis placement define the "Axis" of the plane. It is the axis normal to the plane which gives the orientation of the plane.
The "XDirection" and the "YDirection" of the axis placement define the plane ("XAxis" and "YAxis") .
Constructor & Destructor Documentation
| gce_MakePln::gce_MakePln | ( | const gp_Ax2 & | A2 | ) |
The coordinate system of the plane is defined with the axis placement A2. The "Direction" of A2 defines the normal to the plane. The "Location" of A2 defines the location (origin) of the plane. The "XDirection" and "YDirection" of A2 define the "XAxis" and the "YAxis" of the plane used to parametrize the plane.
Creates a plane with the "Location" point.

Creates a plane from its cartesian equation : A * X + B * Y + C * Z + D = 0.0.
the status is "BadEquation" if Sqrt (A*A + B*B + C*C) <= Resolution from gp.
Make a Pln from gp <ThePln> parallel to another Pln <Pln> and passing through a Pnt <Point>.
| gce_MakePln::gce_MakePln | ( | const gp_Pln & | Pln, |
| const Standard_Real | Dist | ||
| ) |
Make a Pln from gp <ThePln> parallel to another Pln <Pln> at the distance <Dist> which can be greater or less than zero. In the first case the result is at the distance <Dist> to the plane <Pln> in the direction of the normal to <Pln>. Otherwize it is in the opposite direction.
Make a Pln from gp <ThePln> passing through 3 Pnt <P1>,<P2>,<P3>. It returns false if <P1> <P2> <P3> are confused.
Make a Pln from gp <ThePln> perpendicular to the line passing through <P1>,<P2>. The status is "ConfusedPoints" if <P1> <P2> are confused.
| gce_MakePln::gce_MakePln | ( | const gp_Ax1 & | Axis | ) |
Make a pln passing through the location of <Axis>and normal to the Direction of <Axis>. Warning - If an error occurs (that is, when IsDone returns false), the Status function returns:
- gce_BadEquation if Sqrt(A*A + B*B + C*C) is less than or equal to gp::Resolution(),
- gce_ConfusedPoints if P1 and P2 are coincident, or
- gce_ColinearPoints if P1, P2 and P3 are collinear.
