## Detailed Description

Implements construction algorithms for a trimmed cylinder limited by two planes orthogonal to its axis. The result is a Geom_RectangularTrimmedSurface surface. A MakeTrimmedCylinder provides a framework for:

• defining the construction of the trimmed cylinder,
• implementing the construction algorithm, and
• consulting the results. In particular, the Value function returns the constructed trimmed cylinder.

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

Make a cylindricalSurface <Cyl> from Geom Its axis is is <P1P2> and its radius is the distance between <P3> and <P1P2>. The height is the distance between P1 and P2.

 GC_MakeTrimmedCylinder::GC_MakeTrimmedCylinder ( const gp_Circ & Circ, const Standard_Real Height )

Make a cylindricalSurface <Cyl> from gp by its base <Circ>. Its axis is the normal to the plane defined bi <Circ>. <Height> can be greater than zero or lower than zero. In the first case the V parametric direction of the result has the same orientation as the normal to <Circ>. In the other case it has the opposite orientation.

 GC_MakeTrimmedCylinder::GC_MakeTrimmedCylinder ( const gp_Ax1 & A1, const Standard_Real Radius, const Standard_Real Height )

Make a cylindricalSurface <Cyl> from gp by its axis <A1> and its radius <Radius>. It returns NullObject if <Radius> is lower than zero. <Height> can be greater than zero or lower than zero. In the first case the V parametric direction of the result has the same orientation as <A1>. In the other case it has the opposite orientation.

 GC_MakeTrimmedCylinder::GC_MakeTrimmedCylinder ( const gp_Cylinder & Cyl, const gp_Pnt & P, const Standard_Real Height )

Make a RectangularTrimmedSurface <Cylinder> from gp by a cylinder from gp. It is trimmed by the point.

and the heigh <Heigh>. <Height> can be greater than zero or lower than zero. in the first case the limit section is in the side of the positives V paramters of <Cyl> and in the other side if <Heigh> is lower than zero.
