class SelectBasicGeom from IGESSelect inherits SelectExplore
|
|
|
|
---Purpose : This selection returns the basic geometric elements
|
|
-- contained in an IGES Entity
|
|
-- Intended to run a "quick" transfer. I.E. :
|
|
-- - for a Group, considers its Elements
|
|
-- - for a Trimmed or Bounded Surface or a Face (BREP),
|
|
-- considers the 3D curves of each of its loops
|
|
-- - for a Plane (108), considers its Bounding Curve
|
|
-- - for a Curve itself, takes it
|
|
--
|
|
-- 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

Create (mode : Integer) returns mutable SelectBasicGeom;
|
|
---Purpose : 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
|
|
|

CurvesOnly (me) returns Boolean;
|
|
|
|
Explore (me; level : Integer; ent : Transient; G : Graph;
|
|
explored : in out EntityIterator)
|
|
returns Boolean;
|
|
---Purpose : Explores an entity, to take its contained Curves 3d
|
|
-- Works recursively
|
|
|
|
|
|
ExploreLabel (me) returns AsciiString from TCollection;
|
|
---Purpose : Returns a text defining the criterium : "Curves 3d" or
|
|
-- "Basic Geometry"
|
|
|
|
SubCurves (myclass; ent : IGESEntity; explored : in out EntityIterator)
|
|
returns Boolean;
|
|
---Purpose : 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
