class Wireframe from ShapeFix inherits Root from ShapeFix
---Purpose : Provides methods for fixing wireframe of shape
uses
Shape from TopoDS,
Status from ShapeExtend,
Shape from GeomAbs,
HArray1OfReal from TColStd,
MapOfShape from TopTools,
DataMapOfShapeListOfShape from TopTools
is
Create returns Wireframe from ShapeFix;
Create (shape: Shape from TopoDS) returns Wireframe from ShapeFix;
ClearStatuses (me: mutable) is virtual;
---Purpose: Clears all statuses
Load (me : mutable; shape: Shape from TopoDS);
---Purpose: Loads a shape, resets statuses
FixWireGaps (me : mutable) returns Boolean from Standard;
---Purpose : Fixes gaps between ends of curves of adjacent edges
-- (both 3d and pcurves) in wires
-- If precision is 0.0, uses Precision::Confusion().
---Status : See StatusWireGaps() for details
-- OK - No gaps were found
-- DONE1 - Some gaps in 3D were fixed
-- DONE2 - Some gaps in 2D were fixed
-- FAIL1 - Failed to fix some gaps in 3D
-- FAIL2 - Failed to fix some gaps in 2D
---Returns : False if nothing done, else True
FixSmallEdges (me : mutable) returns Boolean from Standard;
---Purpose : Fixes small edges in shape by merging adjacent edges
-- If precision is 0.0, uses Precision::Confusion().
---Status : See StatusSmallEdges() for details
-- OK - No small edges were found
-- DONE1 - Some small edges were fixed
-- FAIL1 - Failed to fix some small edges
---Returns : False if nothing done, else True
CheckSmallEdges (me: mutable; theSmallEdges: out MapOfShape from TopTools;
theEdgeToFaces: out DataMapOfShapeListOfShape from TopTools;
theFaceWithSmall: out DataMapOfShapeListOfShape from TopTools;
theMultyEdges: out MapOfShape from TopTools)
returns Boolean from Standard;
---Purpose: Auxiliary tool for FixSmallEdges which checks for small edges and fills the maps.
-- Returns True if at least one small edge has been found.
MergeSmallEdges (me: mutable; theSmallEdges: in out MapOfShape from TopTools;
theEdgeToFaces: in out DataMapOfShapeListOfShape from TopTools;
theFaceWithSmall: in out DataMapOfShapeListOfShape from TopTools;
theMultyEdges: out MapOfShape from TopTools;
theModeDrop: Boolean = Standard_False;
theLimitAngle: Real = -1)
returns Boolean from Standard;
---Purpose: Auxiliary tool for FixSmallEdges which merges small edges.
-- If theModeDrop is equal to Standard_True then small edges,
-- which cannot be connected with adjacent edges are dropped.
-- Otherwise they are kept.
-- theLimitAngle specifies maximum allowed tangency
-- discontinuity between adjacent edges.
-- If theLimitAngle is equal to -1, this angle is not taken into account.
StatusWireGaps (me; status: Status from ShapeExtend) returns Boolean;
---C++: inline
---Purpose : Decodes the status of the last FixWireGaps.
-- OK - No gaps were found
-- DONE1 - Some gaps in 3D were fixed
-- DONE2 - Some gaps in 2D were fixed
-- FAIL1 - Failed to fix some gaps in 3D
-- FAIL2 - Failed to fix some gaps in 2D
StatusSmallEdges (me; status: Status from ShapeExtend) returns Boolean;
---C++: inline
---Purpose : Decodes the status of the last FixSmallEdges.
-- OK - No small edges were found
-- DONE1 - Some small edges were fixed
-- FAIL1 - Failed to fix some small edges
Shape (me : mutable) returns Shape from TopoDS;
---C++: inline
ModeDropSmallEdges(me : mutable) returns Boolean;
---C++: return &
---C++: inline
---Purpose: Returns mode managing removing small edges.
SetLimitAngle(me:mutable; theLimitAngle : Real);
---C++: inline
---Purpose:Set limit angle for merging edges.
LimitAngle(me) returns Real;
---C++: inline
---Purpose:Get limit angle for merging edges.
