BRepFeat_MakeLinearForm Class Reference

Builds a rib or a groove along a developable, planar surface. The semantics of mechanical features is built around giving thickness to a contour. This thickness can either be symmetrical - on one side of the contour - or dissymmetrical - on both sides. As in the semantics of form features, the thickness is defined by construction of shapes in specific contexts. The development contexts differ, however, in case of mechanical features. Here they include extrusion: More...

const Handle< Geom_Plane > &  P,
const gp_Vec Direction,
const gp_Vec Direction1,

)

contour W, a shape Sbase and a plane P are initialized to serve as the basic elements in the construction of the rib or groove. Direction and Direction1 give The vectors for defining the direction(s) in which thickness will be built up. Fuse offers a choice between:

  • removing matter with a Boolean cut using the setting 0 in case of the groove
  • adding matter with Boolean fusion using the setting 1 in case of the rib.

◆ Add()

void BRepFeat_MakeLinearForm::Add ( const TopoDS_Edge E,
const TopoDS_Face OnFace 
)

Indicates that the edge <E> will slide on the face <OnFace>. Raises ConstructionError if the face does not belong to the basis shape, or the edge to the prismed shape.

◆ Init()

void BRepFeat_MakeLinearForm::Init ( const TopoDS_Shape Sbase,
const TopoDS_Wire W,
const Handle< Geom_Plane > &  P,
const gp_Vec Direction,
const gp_Vec Direction1,
const Standard_Integer  Fuse,
const Standard_Boolean  Modify 
)

Initializes this construction algorithm. A contour W, a shape Sbase and a plane P are initialized to serve as the basic elements in the construction of the rib or groove. The vectors for defining the direction(s) in which thickness will be built up are given by Direction and Direction1. Fuse offers a choice between:

  • removing matter with a Boolean cut using the setting 0 in case of the groove
  • adding matter with Boolean fusion using the setting 1 in case of the rib.

◆ Perform()

void BRepFeat_MakeLinearForm::Perform ( )

Performs a prism from the wire to the plane along the basis shape Sbase. Reconstructs the feature topologically.

◆ Propagate()

Standard_Boolean BRepFeat_MakeLinearForm::Propagate ( TopTools_ListOfShape L,
const TopoDS_Face F,
const gp_Pnt FPoint,
const gp_Pnt LPoint,
Standard_Boolean falseside 
)

◆ TransformShapeFU()

void BRepFeat_MakeLinearForm::TransformShapeFU ( const Standard_Integer  flag)

Limits construction of the linear form feature by using one of the following three semantics:

  • from a limiting plane
  • to a limiting plane
  • from one limiting plane to another. The setting is provided by a flag, flag, which can be set to from and/or until. The third semantic possibility above is selected by showing both from and until at the same time.
