Standard_Integer vstart,
Standard_Integer vend 
) const

Returns the definition of an Edge (3D) given its rank.

Handle< IGESSolid_EdgeList > IGESSolid_TopoBuilder::EdgeList ( ) const

void IGESSolid_TopoBuilder::EndFace ( const Standard_Integer  orientation)

Closes the definition of the current Face, fills it and adds it to the current Shell with an orientation flag (0/1)

void IGESSolid_TopoBuilder::EndLists ( )
protected

Closes the definition of Vertex and Edge Lists Warning : Called only by EndSimpleShell and EndSolid.

void IGESSolid_TopoBuilder::EndLoop ( )
protected

Closes the definition of a Loop and fills it Warning : EndLoop should not be called directly but through SetOuter or AddInner, which work on the current Face.

void IGESSolid_TopoBuilder::EndShell ( )
protected

Closes the definition of the current Shell Warning : EndShell should not be called directly but through EndSimpleShell (for a simple Shell), SetMainShell (for main Shell of a Solid) or AddVoidShell (to a Solid)

void IGESSolid_TopoBuilder::EndSimpleShell ( )

Closes the whole definition as that of a simple Shell.

void IGESSolid_TopoBuilder::EndSolid ( )

Closes the whole definition as that of a ManifoldSolid Its call is exclusive from that of EndSimpleShell.

void IGESSolid_TopoBuilder::MakeEdge ( const Standard_Integer  edgetype,
const Standard_Integer  edge3d,
const Standard_Integer  orientation 
)

Defines an Edge(UV), to be added in the current Loop by EndEdge <edgetype> gives the type of the edge <edge3d> identifies the Edge(3D) used as support The EdgeList is allways the current one <orientation gives the orientation flag It is then necessary to :

  • give the parametric curves
  • close the definition of this edge(UV) by EndEdge, else the next call to MakeEdge will erase this one
void IGESSolid_TopoBuilder::MakeFace ( const Handle< IGESData_IGESEntity > &  surface)

Begins the definition of a new Face, on a surface All Loops defined by MakeLoop will be added in it, according the closing call : SetOuter for the Outer Loop (by default, if SetOuter is not called, no OuterLoop is defined); AddInner for the list of Inner Loops (there can be none)

void IGESSolid_TopoBuilder::MakeLoop ( )

Begins the definition of a new Loop : it is the Current Loop All Edges (UV) defined by MakeEdge/EndEdge will be added in it The Loop can then be referenced but is empty. It will be filled with its Edges(UV) by EndLoop (from SetOuter/AddInner)

void IGESSolid_TopoBuilder::MakeShell ( )

Begins the definition of a new Shell (either Simple or in a Solid)

Standard_Integer IGESSolid_TopoBuilder::NbEdges ( ) const

Returns the count of recorded Edges (3D)

Standard_Integer IGESSolid_TopoBuilder::NbVertices ( ) const

Returns the count of already recorded Vertices.

void IGESSolid_TopoBuilder::SetMainShell ( const Standard_Integer  orientation)

Closes the definition of the current Shell as for the Main Shell of a Solid, with an orientation flag (0/1)

void IGESSolid_TopoBuilder::SetOuter ( )

Closes the current Loop and sets it Loop as Outer Loop. If no current Loop has yet been defined, does nothing.

Handle< IGESSolid_Shell > IGESSolid_TopoBuilder::Shell ( ) const

Returns the current Shell. The current Shell is created empty by MakeShell and filled by EndShell.

Handle< IGESSolid_ManifoldSolid > IGESSolid_TopoBuilder::Solid ( ) const

Returns the current ManifoldSolid. It is created empty by Create and filled by EndSolid.

const gp_XYZ& IGESSolid_TopoBuilder::Vertex ( const Standard_Integer  num) const

Returns a Vertex, given its rank.

Handle< IGESSolid_VertexList > IGESSolid_TopoBuilder::VertexList ( ) const

Returns the VertexList. It can be referenced, but it remains empty until call to EndShell or EndSolid.
