 IGESSelect_SelectBasicGeom (const Standard_Integer mode)
 Creates a SelectBasicGeom, which allways works recursively
mode = -1 : Returns Surfaces (without trimming)
mode = +1 : Returns Curves 3D (free or bound of surface)
mode = +2 : Returns Basic Curves 3D : as 1 but CompositeCurves
are returned in detail
mode = 0 : both

Standard_Boolean CurvesOnly () const
Standard_Boolean Explore (const Standard_Integer level, const Handle< Standard_Transient > &ent, const Interface_Graph &G, Interface_EntityIterator &explored) const
 Explores an entity, to take its contained Curves 3d
Works recursively

TCollection_AsciiString ExploreLabel () const
 Returns a text defining the criterium : "Curves 3d" or
"Basic Geometry"

Static Public Member Functions

static Standard_Boolean SubCurves (const Handle< IGESData_IGESEntity > &ent, Interface_EntityIterator &explored)
 This method can be called from everywhere to get the curves
as sub-elements of a given curve :
CompositeCurve : explored lists its subs + returns True
Any Curve : explored is not filled but returned is True
Other : returned is False


Detailed Description

      - for a Group, considers its Elements <br>
      - for a Trimmed or Bounded Surface or a Face (BREP), <br>
        considers the 3D curves of each of its loops <br>
      - for a Plane (108), considers its Bounding Curve <br>
      - for a Curve itself, takes it <br>


Also, FREE surfaces are taken, because curve 3d is known for
them. (the ideal should be to have their natural bounds)

If <curvesonly> is set, ONLY curves-3d are returned
