class CheckSmallFace from ShapeAnalysis
---Purpose:
uses
Shape from TopoDS,
Face from TopoDS,
Pnt from gp,
Edge from TopoDS,
Compound from TopoDS,
DataMapOfShapeShape from TopTools,
DataMapOfShapeListOfReal from ShapeAnalysis,
DataMapOfShapeListOfShape from TopTools,
Status from ShapeExtend
is
Create returns CheckSmallFace from ShapeAnalysis;
---Purpose :Creates an empty tool
-- CheckShape (me : in out; S : Shape from TopoDS);
---Purpose : Checks a Shape i.e. each of its faces, records checks as
-- diagnostics in the <infos>
--
-- If <infos> has not been set before, no check is done
--
-- For faces which are in a Shell, topological data are recorded
-- to allow recovering connectivities after fixing or removing
-- the small faces or parts of faces
-- CheckFace (me : in out; F : Face from TopoDS; inshell : Boolean);
---Purpose : Enchains various checks on a face
-- inshell : to compute more informations, relevant to topology
IsSpotFace (me; F : Face from TopoDS;
spot : out Pnt from gp; spotol : out Real;
tol : Real = -1.0) returns Integer;
---Purpose : Checks if a Face is as a Spot
-- Returns 0 if not, 1 if yes, 2 if yes and all vertices are the
-- same
-- By default, considers the tolerance zone of its vertices
-- A given value <tol> may be given to check a spot of this size
-- If a Face is a Spot, its location is returned in <spot>, and
-- <spotol> returns an equivalent tolerance, which is computed as
-- half of max dimension of min-max box of the face
CheckSpotFace (me : in out; F : Face from TopoDS; tol : Real = -1.0) returns Boolean;
---Purpose : Acts as IsSpotFace, but records in <infos> a diagnostic
-- "SpotFace" with the Pnt as value (data "Location")
IsStripSupport (me: in out; F : Face; tol : Real = -1.0) returns Boolean;
---Purpose : Checks if a Face lies on a Surface which is a strip
-- So the Face is a strip. But a Face may be a strip elsewhere ..
--
-- A given value <tol> may be given to check max width
-- By default, considers the tolerance zone of its edges
-- Returns 0 if not a strip support, 1 strip in U, 2 strip in V
CheckStripEdges (me; E1, E2 : Edge from TopoDS; tol : Real;
dmax : out Real) returns Boolean;
---Purpose : Checks if two edges define a strip, i.e. distance maxi below
-- tolerance, given or some of those of E1 and E2
FindStripEdges (me: in out; F : Face from TopoDS;
E1, E2 : out Edge from TopoDS; tol : Real;dmax : out Real) returns Boolean;
---Purpose : Searchs for two and only two edges up tolerance
-- Returns True if OK, false if not 2 edges
-- If True, returns the two edges and their maximum distance
CheckSingleStrip (me : in out; F : Face from TopoDS; E1,E2 : in out Edge from TopoDS;tol : Real = -1.0)
returns Boolean;
---Purpose : Checks if a Face is a single strip, i.e. brings two great
-- edges which are confused on their whole length, possible other
-- edges are small or null length
--
-- Returns 0 if not a strip support, 1 strip in U, 2 strip in V
-- Records diagnostic in info if it is a single strip
CheckStripFace (me : in out; F : Face from TopoDS;E1,E2 : in out Edge from TopoDS; tol : Real = -1.0)
returns Boolean;
---Purpose : Checks if a Face is as a Strip
-- Returns 0 if not or non determined, 1 if in U, 2 if in V
-- By default, considers the tolerance zone of its edges
-- A given value <tol> may be given to check a strip of max this width
--
-- If a Face is determined as a Strip, it is delinited by two
-- lists of edges. These lists are recorded in diagnostic
-- Diagnostic "StripFace" brings data "Direction" (U or V),
-- "List1" , "List2" (if they could be computed)
CheckSplittingVertices (me : in out; F : Face from TopoDS; MapEdges :in out DataMapOfShapeListOfShape from TopTools;
MapParam :in out DataMapOfShapeListOfReal from ShapeAnalysis; theAllVert : in out Compound from TopoDS) returns Integer;
---Purpose : Checks if a Face brings vertices which split it, either
-- confused with non adjacent vertices, or confused with their
-- projection on non adjacent edges
-- Returns the count of found splitting vertices
-- Each vertex then brings a diagnostic "SplittingVertex",
-- with data : "Face" for the face, "Edge" for the split edge
CheckPin (me : in out; F : Face from TopoDS; whatrow,sence : in out Integer) returns Boolean;
---Purpose : Checks if a Face has a pin, which can be edited
-- No singularity : no pin, returns 0
-- If there is a pin, checked topics, with returned value :
-- - 0 : nothing to do more
-- - 1 : "smooth", i.e. not a really sharp pin
-- -> diagnostic "SmoothPin"
-- - 2 : stretched pin, i.e. is possible to relimit the face by
-- another vertex, so that this vertex still gives a pin
-- -> diagnostic "StretchedPin" with location of vertex (Pnt)
CheckTwisted (me : in out; F : Face from TopoDS; paramu,paramv : in out Real) returns Boolean;
---Purpose : Checks if a Face is twisted (apart from checking Pin, i.e. it
-- does not give information on pin, only "it is twisted")
CheckPinFace(me : in out; F : Face from TopoDS;mapEdges : in out DataMapOfShapeShape from TopTools;toler : Real = -1.0) returns Boolean;
CheckPinEdges(me; theFirstEdge: Edge from TopoDS;theSecondEdge: Edge from TopoDS; coef1,coef2 : Real;toler : Real) returns Boolean;
Status (me; status: Status from ShapeExtend) returns Boolean;
---Purpose: Returns the status of last call to Perform()
-- ShapeExtend_OK : face was OK, nothing done
-- ShapeExtend_DONE1: some wires are fixed
-- ShapeExtend_DONE2: orientation of wires fixed
-- ShapeExtend_DONE3: missing seam added
-- ShapeExtend_DONE4: small area wire removed
-- ShapeExtend_DONE5: natural bounds added
-- ShapeExtend_FAIL1: some fails during fixing wires
-- ShapeExtend_FAIL2: cannot fix orientation of wires
-- ShapeExtend_FAIL3: cannot add missing seam
-- ShapeExtend_FAIL4: cannot remove small area wire
---C++: inline
SetTolerance (me : in out; tol : Real);
---Purpose : Sets a fixed Tolerance to check small face
-- By default, local tolerance zone is considered
---C++: inline
-- SetMaxTolerance (me : in out; tol : Real);
---Purpose : Sets a fixed MaxTolerance to check small face
---C++: inline
-- SetMinTolerance (me : in out; tol : Real);
---Purpose : Sets a fixed Tolerance to check small face
-- By default, local tolerance zone is considered
---C++: inline
-- MaxTolerance (me : in out);
---Purpose : Unset fixed tolerance, comes back to local tolerance zones
---C++: inline
-- MinTolerance (me : in out);
---Purpose : Unset fixed tolerance, comes back to local tolerance zones
---C++: inline
Tolerance (me) returns Real;
---Purpose : Returns the tolerance to check small faces, negative value if
-- local tolerances zones are to be considered

StatusSpot (me; status: Status from ShapeExtend) returns Boolean;

StatusStrip(me; status: Status from ShapeExtend) returns Boolean;
