DEFINE_STANDARD_ALLOC | GC_MakeCylindricalSurface (const gp_Ax2 &A2, const Standard_Real Radius) |
A2 defines the local coordinate system of the cylindrical surface. The "ZDirection" of A2 defines the direction of the surface's axis of symmetry. At the creation the parametrization of the surface is defined such that the normal Vector (N = D1U ^ D1V) is oriented towards the "outside region" of the surface. Warnings : It is not forbidden to create a cylindrical surface with Radius = 0.0 Status is "NegativeRadius" if Radius < 0.0 | |
GC_MakeCylindricalSurface (const gp_Cylinder &C) | |
Creates a CylindricalSurface from a non persistent Cylinder from package gp. | |
GC_MakeCylindricalSurface (const gp_Cylinder &Cyl, const gp_Pnt &Point) | |
Make a CylindricalSurface from Geom <TheCylinder> parallel to another CylindricalSurface <Cylinder> and passing through a Pnt <Point>. | |
GC_MakeCylindricalSurface (const gp_Cylinder &Cyl, const Standard_Real Dist) | |
Make a CylindricalSurface from Geom <TheCylinder> parallel to another CylindricalSurface <Cylinder> at the distance <Dist> which can be greater or lower than zero. The radius of the result is the absolute value of the radius of <Cyl> plus <Dist> | |
GC_MakeCylindricalSurface (const gp_Pnt &P1, const gp_Pnt &P2, const gp_Pnt &P3) | |
Make a CylindricalSurface from Geom <TheCylinder> passing through 3 Pnt <P1>,<P2>,<P3>. Its axis is <P1P2> and its radius is the distance between <P3> and <P1P2> | |
GC_MakeCylindricalSurface (const gp_Ax1 &Axis, const Standard_Real Radius) | |
Make a CylindricalSurface by its axis <Axis> and radius <Radius>. | |

* Create a CylindricalSurface parallel to another and <br> passing through a point. <br> * Create a CylindricalSurface parallel to another at a <br> distance <br> <Dist>. <br> * Create a CylindricalSurface passing through 3 points. <br> * Create a CylindricalSurface by its axis and radius. <br> * Create a cylindricalSurface by its circular base. <br>
The local coordinate system of the CylindricalSurface is defined
with an axis placement (see class ElementarySurface).
The "ZAxis" is the symmetry axis of the CylindricalSurface,
it gives the direction of increasing parametric value V.
The parametrization range is :
U [0, 2*PI], V ]- infinite, + infinite[
The "XAxis" and the "YAxis" define the placement plane of the
surface (Z = 0, and parametric value V = 0) perpendicular to
the symmetry axis. The "XAxis" defines the origin of the
parameter U = 0. The trigonometric sense gives the positive
orientation for the parameter U.
