	The U parametric direction of the surface is oriented from U1 to U2. The V parametric direction of the surface is oriented from V1 to V2. These two directions define the orientation of the surface (normal). If the surface is not periodic USense and VSense are not used for the construction. If the surface S is periodic in one direction USense and VSense give the available part of the surface. By default in this case the surface has the same orientation as the basis surface S. The returned surface is not closed and not periodic. ConstructionError Raised if S is not periodic in the UDirection and U1 or U2 are out of the bounds of S. S is not periodic in the VDirection and V1 or V2 are out of the bounds of S. U1 = U2 or V1 = V2.
	Geom_RectangularTrimmedSurface (const occ::handle< Geom_Surface > &S, const double Param1, const double Param2, const bool UTrim, const bool Sense=true)
	The basis surface S is only trim in one parametric direction. If UTrim = True the surface is trimmed in the U parametric direction else the surface is trimmed in the V parametric direction. In the considered parametric direction the resulting surface is oriented from Param1 to Param2. If S is periodic Sense gives the available part of the surface. By default the trimmed surface has the same orientation as the basis surface S in the considered parametric direction (Sense = True). If the basis surface S is closed or periodic in the parametric direction opposite to the trimming direction the trimmed surface has the same characteristics as the surface S in this direction. Warnings : In this package the entities are not shared. The RectangularTrimmedSurface is built with a copy of the surface S. So when S is modified the RectangularTrimmedSurface is not modified Raised if S is not periodic in the considered parametric direction and Param1 or Param2 are out of the bounds of S.

Detailed Description

Describes a portion of a surface (a patch) limited by two values of the u parameter in the u parametric direction, and two values of the v parameter in the v parametric direction. The domain of the trimmed surface must be within the domain of the surface being trimmed. The trimmed surface is defined by:

• the basis surface, and
• the values (umin, umax) and (vmin, vmax) which limit it in the u and v parametric directions. The trimmed surface is built from a copy of the basis surface. Therefore, when the basis surface is modified the trimmed surface is not changed. Consequently, the trimmed surface does not necessarily have the same orientation as the basis surface. Warning: The case of surface being trimmed is periodic and parametrics values are outside the domain is possible. But, domain of the trimmed surface can be translated by (n X) the period.
