BRepFeat_Gluer Class Reference

One of the most significant aspects of BRepFeat functionality is the use of local operations as opposed to global ones. In a global operation, you would first construct a form of the type you wanted in your final feature, and then remove matter so that it could fit into your initial basis object. In a local operation, however, you specify the domain of the feature construction with aspects of the shape on which the feature is being created. These semantics are expressed in terms of a member shape of the basis shape from which - or up to which - matter will be added or removed. As a result, local operations make calculations simpler and faster than global operations. Glueing uses wires or edges of a face in the basis shape. These are to become a part of the feature. They are first cut out and then projected to a plane outside or inside the basis shape. By rebuilding the initial shape incorporating the edges and the faces of the tool, protrusion features can be constructed. More...

Detailed Description

One of the most significant aspects of BRepFeat functionality is the use of local operations as opposed to global ones. In a global operation, you would first construct a form of the type you wanted in your final feature, and then remove matter so that it could fit into your initial basis object. In a local operation, however, you specify the domain of the feature construction with aspects of the shape on which the feature is being created. These semantics are expressed in terms of a member shape of the basis shape from which - or up to which - matter will be added or removed. As a result, local operations make calculations simpler and faster than global operations. Glueing uses wires or edges of a face in the basis shape. These are to become a part of the feature. They are first cut out and then projected to a plane outside or inside the basis shape. By rebuilding the initial shape incorporating the edges and the faces of the tool, protrusion features can be constructed.

Constructor & Destructor Documentation

◆ BRepFeat_Gluer() [1/2]

BRepFeat_Gluer::BRepFeat_Gluer ( )

Initializes an empty constructor.

◆ BRepFeat_Gluer() [2/2]

BRepFeat_Gluer::BRepFeat_Gluer ( const TopoDS_Shape Snew,
const TopoDS_Shape Sbase 
)

Initializes the shapes to be glued, the new shape Snew and the basis shape Sbase.

Member Function Documentation

◆ BasisShape()

const TopoDS_Shape& BRepFeat_Gluer::BasisShape ( ) const

Returns the basis shape of the compound shape.

◆ Bind() [1/2]

void BRepFeat_Gluer::Bind ( const TopoDS_Face Fnew,
const TopoDS_Face Fbase 
)

Defines a contact between Fnew on the new shape Snew and Fbase on the basis shape Sbase. Informs other methods that Fnew in the new shape Snew is connected to the face Fbase in the basis shape Sbase. The contact faces of the glued shape must not have parts outside the contact faces of the basis shape. This indicates that glueing is possible.

◆ Bind() [2/2]

void BRepFeat_Gluer::Bind ( const TopoDS_Edge Enew,
const TopoDS_Edge Ebase 
)

nforms other methods that the edge Enew in the new shape is the same as the edge Ebase in the basis shape and is therefore attached to the basis shape. This indicates that glueing is possible.

◆ Build()

virtual void BRepFeat_Gluer::Build ( )
overridevirtual

This is called by Shape(). It does nothing but may be redefined.

Reimplemented from BRepBuilderAPI_MakeShape.

◆ GluedShape()

const TopoDS_Shape& BRepFeat_Gluer::GluedShape ( ) const

Returns the resulting compound shape.

◆ Init()

void BRepFeat_Gluer::Init ( const TopoDS_Shape Snew,
const TopoDS_Shape Sbase 
)

Initializes the new shape Snew and the basis shape Sbase for the local glueing operation.

◆ IsDeleted()

virtual Standard_Boolean BRepFeat_Gluer::IsDeleted ( const TopoDS_Shape F)
overridevirtual

returns the status of the Face after the shape creation.

Reimplemented from BRepBuilderAPI_MakeShape.

◆ Modified()

returns the list of generated Faces.

Reimplemented from BRepBuilderAPI_MakeShape.

◆ OpeType()

LocOpe_Operation BRepFeat_Gluer::OpeType ( ) const

Determine which operation type to use glueing or sliding.
