Data Structures

class  gp_Pln
 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 right-handed, 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:
