	)

staticprotected

The plane is defined by gp_Pln object and the status. The status can have one of the following values:

0 plane is not set.
1 origin of the plane is fixed. The plane is defined by 1 or several coincident points.
2 origin + OX axis of the plane is fixed. The plane is defined by 2 or more points that lie on a particular line.
3 plane is fixed. Plane is defined by 3 not coincident points.

Parameters

thePoints	the points.
thePlane	the current plane on input. It can be modified on output.
thePlnStatus	the current status on input. It can be modified on output.
