 ShapeExtend_Explorer ()
 Creates an object Explorer

TopoDS_Shape CompoundFromSeq (const Handle< TopTools_HSequenceOfShape > &seqval) const
 Converts a sequence of Shapes to a Compound

Handle_TopTools_HSequenceOfShape SeqFromCompound (const TopoDS_Shape &comp, const Standard_Boolean expcomp) const
 Converts a Compound to a list of Shapes
if <comp> is not a compound, the list contains only <comp>
if <comp> is Null, the list is empty
if <comp> is a Compound, its sub-shapes are put into the list
then if <expcomp> is True, if a sub-shape is a Compound, it
is not put to the list but its sub-shapes are (recursive)

void ListFromSeq (const Handle< TopTools_HSequenceOfShape > &seqval, TopTools_ListOfShape &lisval, const Standard_Boolean clear=Standard_True) const
 Converts a Sequence of Shapes to a List of Shapes
<clear> if True (D), commands the list to start from scratch
else, the list is cumulated

Handle_TopTools_HSequenceOfShape SeqFromList (const TopTools_ListOfShape &lisval) const
 Converts a List of Shapes to a Sequence of Shapes

TopAbs_ShapeEnum ShapeType (const TopoDS_Shape &shape, const Standard_Boolean compound) const
 Returns the type of a Shape: true type if <compound> is False
If <compound> is True and <shape> is a Compound, iterates on
its items. If all are of the same type, returns this type.
Else, returns COMPOUND. If it is empty, returns SHAPE
For a Null Shape, returns SHAPE

TopoDS_Shape SortedCompound (const TopoDS_Shape &shape, const TopAbs_ShapeEnum type, const Standard_Boolean explore, const Standard_Boolean compound) const
 Builds a COMPOUND from the given shape.
It explores the shape level by level, according to the
<explore> argument. If <explore> is False, only COMPOUND
items are explored, else all items are.
The following shapes are added to resulting compound:

void DispatchList (const Handle< TopTools_HSequenceOfShape > &list, Handle< TopTools_HSequenceOfShape > &vertices, Handle< TopTools_HSequenceOfShape > &edges, Handle< TopTools_HSequenceOfShape > &wires, Handle< TopTools_HSequenceOfShape > &faces, Handle< TopTools_HSequenceOfShape > &shells, Handle< TopTools_HSequenceOfShape > &solids, Handle< TopTools_HSequenceOfShape > &compsols, Handle< TopTools_HSequenceOfShape > &compounds) const
 Dispatches starting list of shapes according to their type,
to the appropriate resulting lists
For each of these lists, if it is null, it is firstly created
else, new items are appended to the already existing ones

  • shapes which comply to <type>
  • if <type> is WIRE, considers also free edges (and makes wires)
  • if <type> is SHELL, considers also free faces (and makes shells)
    If <compound> is True, gathers items in compounds which
    correspond to starting COMPOUND,SOLID or SHELL containers, or
    items directly contained in a Compound
