## Detailed Description

This class implements the following algorithms used to create a Plane from gp.

• Create a Plane parallel to another and passing through a point.
• Create a Plane passing through 3 points.
• Create a Plane by its normal A MakePlane object provides a framework for:
• defining the construction of the plane,
• implementing the construction algorithm, and
• consulting the results. In particular, the Value function returns the constructed plane.

## ◆ GC_MakePlane() [1/7]

 GC_MakePlane::GC_MakePlane ( const gp_Pln & Pl )

Creates a plane from a non persistent plane from package gp.

## ◆ GC_MakePlane() [2/7]

 GC_MakePlane::GC_MakePlane ( const gp_Pnt & P, const gp_Dir & V )

P is the "Location" point or origin of the plane. V is the direction normal to the plane.

## ◆ GC_MakePlane() [3/7]

 GC_MakePlane::GC_MakePlane ( const Standard_Real A, const Standard_Real B, const Standard_Real C, const Standard_Real D )

Creates a plane from its cartesian equation : Ax + By + Cz + D = 0.0 Status is "BadEquation" if Sqrt (A*A + B*B + C*C) <= Resolution from gp.

## ◆ GC_MakePlane() [4/7]

 GC_MakePlane::GC_MakePlane ( const gp_Pln & Pln, const gp_Pnt & Point )

Make a Plane from Geom <ThePlane> parallel to another Pln <Pln> and passing through a Pnt <Point>.

## ◆ GC_MakePlane() [5/7]

 GC_MakePlane::GC_MakePlane ( const gp_Pln & Pln, const Standard_Real Dist )

Make a Plane from Geom <ThePlane> parallel to another Pln <Pln> at the distance <Dist> which can be greater or lower 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 oposite direction.

## ◆ GC_MakePlane() [6/7]

 GC_MakePlane::GC_MakePlane ( const gp_Pnt & P1, const gp_Pnt & P2, const gp_Pnt & P3 )
