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.

Public Member Functions | |
DEFINE_STANDARD_ALLOC | BRepFeat_Gluer () |
Initializes an empty constructor | |
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. | |
void | Init (const TopoDS_Shape &Snew, const TopoDS_Shape &Sbase) |
Initializes the new shape Snew and the basis shape Sbase for the local glueing operation. | |
void | 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. | |
void | 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. | |
LocOpe_Operation | OpeType () const |
Determine which operation type to use glueing or sliding. | |
const TopoDS_Shape & | BasisShape () const |
Returns the basis shape of the compound shape. | |
const TopoDS_Shape & | GluedShape () const |
Returns the resulting compound shape. | |
virtual void | Build () |
This is called by Shape(). It does nothing but may be redefined. | |
virtual Standard_Boolean | IsDeleted (const TopoDS_Shape &F) |
returns the status of the Face after the shape creation. | |
virtual const TopTools_ListOfShape & | Modified (const TopoDS_Shape &F) |
returns the list of generated Faces. |
