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 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 |
- 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
