Detailed Description

FaceMaker class is the base class for implementing various "smart" face making routines.

This was created to address the problem of multiple private implementations of making faces with holes, which are quite complex. The two most important facemaking routines then was: one in Part Extrude, and one in PartDesign (there, it is used in every sketch-based feature). Plus, another one (new) was needed for filling 2D offset.

Member Function Documentation

addShape()

void Part::FaceMaker::addShape ( const TopoDS_Shape &  sh )

virtual

addShape: add another wire, edge, or compound.

If compound is added, its internals will be treated as isolated from the rest, and the compounding structure of result will follow.

Parameters

sh

References myCompounds, mySourceShapes, and myWires.

addWire()

void Part::FaceMaker::addWire ( const TopoDS_Wire &  w )

virtual

Referenced by Part::TopoShape::makeOffset2D(), and Path::Area::makeSections().

Build()

void Part::FaceMaker::Build ( )

virtual

Reimplemented in Part::FaceMakerExtrusion.

Build_Essence()

virtual void Part::FaceMaker::Build_Essence ( )

protectedpure virtual

Build_Essence: build routine that can assume there is no nesting.

Implementing instructions: Add new faces (or whatever) to myShapesToReturn. The rest is done by base class's Build(). Please ignore contents of myCompounds in implementation. If special handling of nesting is required, override whole Build().

Implemented in Part::FaceMakerSimple, Part::FaceMakerBullseye, Part::FaceMakerCheese, and Part::FaceMakerExtrusion.

ConstructFromType() [2/2]

References ConstructFromType(), Base::Type::fromName(), and Base::Type::isBad().

Referenced by Build(), ConstructFromType(), Part::Face::execute(), Part::Revolution::execute(), Part::Extrusion::extrudeShape(), and Part::TopoShape::makeFace().

Face()

const TopoDS_Face & Part::FaceMaker::Face ( )

virtual

Face: returns the face (result).

If result is not a single face, throws Base::TypeError. (hint: use .Shape() instead)

Returns

throwNotImplemented()

void Part::FaceMaker::throwNotImplemented ( )

staticprotected

useCompound()

void Part::FaceMaker::useCompound ( const TopoDS_Compound &  comp )

virtual

useCompound: add children of compound to the FaceMaker.

Note that this is different from addShape(comp) - structure is lost. The compound is NOT expanded recursively.

Parameters

comp
