Constructor & Destructor Documentation

◆ ShapeAnalysis_CheckSmallFace()

ShapeAnalysis_CheckSmallFace::ShapeAnalysis_CheckSmallFace ( )

Creates an empty tool 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 Enchains various checks on a face inshell : to compute more informations, relevant to topology

Member Function Documentation

◆ CheckPin()

Standard_Boolean ShapeAnalysis_CheckSmallFace::CheckPin ( const TopoDS_Face F,
Standard_Integer whatrow,
Standard_Integer sence 
)

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)

◆ CheckPinEdges()

Standard_Boolean ShapeAnalysis_CheckSmallFace::CheckPinEdges ( const TopoDS_Edge theFirstEdge,
const TopoDS_Edge theSecondEdge,

Standard_Boolean ShapeAnalysis_CheckSmallFace::CheckSingleStrip ( const TopoDS_Face F,
TopoDS_Edge E1,
TopoDS_Edge E2,
const Standard_Real  tol = -1.0

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

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.

◆ CheckSpotFace()

Standard_Boolean ShapeAnalysis_CheckSmallFace::CheckSpotFace ( const TopoDS_Face F,
