| gp_Cone () |
| Creates an indefinite Cone.
|
| gp_Cone (const gp_Ax3 &A3, const Standard_Real Ang, const Standard_Real Radius) |
| Creates an infinite conical surface. A3 locates the cone
in the space and defines the reference plane of the surface.
Ang is the conical surface semi-angle between 0 and PI/2 radians.
Radius is the radius of the circle in the reference plane of
the cone.
Raises ConstructionError
. if Radius is lower than 0.0
. Ang < Resolution from gp or Ang >= (PI/2) - Resolution.
|
void | SetAxis (const gp_Ax1 &A1) |
| Changes the symmetry axis of the cone. Raises ConstructionError
the direction of A1 is parallel to the "XDirection"
of the coordinate system of the cone.
|
void | SetLocation (const gp_Pnt &Loc) |
| Changes the location of the cone.
|
void | SetPosition (const gp_Ax3 &A3) |
