Detailed Description

Describes functions to build draft prism topologies from basis shape surfaces. These can be depressions or protrusions. The semantics of draft prism feature creation is based on the construction of shapes:

along a length
up to a limiting face
from a limiting face to a height. The shape defining construction of the draft prism feature can be either the supporting edge or the concerned area of a face. In case of the supporting edge, this contour can be attached to a face of the basis shape by binding. When the contour is bound to this face, the information that the contour will slide on the face becomes available to the relevant class methods. In case of the concerned area of a face, you could, for example, cut it out and move it to a different height which will define the limiting face of a protrusion or depression.

Constructor & Destructor Documentation

◆ BRepFeat_MakeDPrism() [1/2]

BRepFeat_MakeDPrism::BRepFeat_MakeDPrism	(	const TopoDS_Shape &	Sbase,
		const TopoDS_Face &	Pbase,
		const TopoDS_Face &	Skface,
		const double	Angle,
		const int	Fuse,
		const bool	Modify )

inline

A face Pbase is selected in the shape Sbase to serve as the basis for the draft prism. The draft will be defined by the angle Angle and Fuse offers a choice between:

removing matter with a Boolean cut using the setting 0
adding matter with Boolean fusion using the setting 1. The sketch face Skface serves to determine the type of operation. If it is inside the basis shape, a local operation such as glueing can be performed. Initializes the draft prism class
