• Creates empty tool.

Return type:None

DispatchWires()

• Creates new faces from the set of (closed) wires. Each wire is put on corresponding patch in the composite surface, and all pcurves on the initial (pseudo)face are reassigned to that surface. If several wires are one inside another, single face is created.

Return type:Handle_ShapeAnalysis_TransferParameters

Init()

• Initializes with composite surface, face and precision. Here face defines both set of wires and way of getting pcurves. Precision is used (together with tolerance of edges) for handling subtle cases, such as tangential intersections.

Parameters:

• L (TopLoc_Location &) –
• Face (TopoDS_Face &) –
• Prec (float) –

Return type:

SetTransferParamTool()

• Sets tool for transfer parameters from 3d to 2d and vice versa.

Parameters:TransferParam (Handle_ShapeAnalysis_TransferParameters &) – Return type:None

SplitEdges()

• Splits edges in the original shape by grid. This is a part of Perform() which does not produce any resulting shape; the only result is filled context where splittings are recorded. //! NOTE: If edge is splitted, it is replaced by wire, and order of edges in the wire corresponds to FORWARD orientation of the edge.

Return type:None

Status()

• Queries status of last call to Perform() OK : nothing done (some kind of error) DONE1: splitting is done, at least one new face created DONE2: splitting is done, several new faces obtained FAIL1: misoriented wire encountered (handled) FAIL2: recoverable parity error FAIL3: edge with no pcurve on supporting face FAIL4: unrecoverable algorithm error (parity check)

Return type:

bool

• Fixes edge if pcurve is directed opposite to 3d curve Check is done by call to the function ShapeAnalysis_Edge::CheckCurve3dWithPCurve() Warning: For seam edge this method will check and fix the pcurve in only one direction. Hence, it should be called twice for seam edge: once with edge orientation FORWARD and once with REVERSED. Returns: False if nothing done, True if reversed (status DONE) Status: OK - pcurve OK, nothing done FAIL1 - no pcurve FAIL2 - no 3d curve DONE1 - pcurve was reversed

Parameters:

• surface (Handle_Geom_Surface &) –
• location (TopLoc_Location &) –

Return type:

bool

FixSameParameter()

• Tries to make edge SameParameter and sets corresponding tolerance and SameParameter flag. First, it makes edge same range if SameRange flag is not set. //! If flag SameParameter is set, this method calls the function ShapeAnalysis_Edge::CheckSameParameter() that calculates the maximal deviation of pcurves of the edge from its 3d curve. If deviation > tolerance, the tolerance of edge is increased to a value of deviation. If deviation < tolerance nothing happens. //! If flag SameParameter is not set, this method chooses the best variant (one that has minimal tolerance), either a. only after computing deviation (as above) or b. after calling standard procedure BRepLib::SameParameter and computing deviation (as above). If <tolerance> > 0, it is used as parameter for BRepLib::SameParameter, otherwise, tolerance of the edge is used. //! Use : Is to be called after all pcurves and 3d curve of the edge are correctly computed Remark : SameParameter flag is always set to True after this method Returns: True, if something done, else False Status : OK - edge was initially SameParameter, nothing is done FAIL1 - computation of deviation of pcurves from 3d curve has failed FAIL2 - BRepLib::SameParameter() has failed DONE1 - tolerance of the edge was increased DONE2 - flag SameParameter was set to True (only if BRepLib::SameParameter() did not set it) DONE3 - edge was modified by BRepLib::SameParameter() to SameParameter DONE4 - not used anymore DONE5 - if the edge resulting from BRepLib has been chosen, i.e. variant b. above (only for edges with not set SameParameter)

Parameters:

• edge (TopoDS_Edge &) –

Parameters:num (int) – Return type:bool

FixEdgeCurves()

• Groups the fixes dealing with 3d and pcurves of the edges. The order of the fixes and the default behaviour are: ShapeFix_Edge::FixReversed2d ShapeFix_Edge::FixRemovePCurve (only if forced) ShapeFix_Edge::FixAddPCurve ShapeFix_Edge::FixRemoveCurve3d (only if forced) ShapeFix_Edge::FixAddCurve3d FixSeam, FixShifted, ShapeFix_Edge::FixSameParameter

FixGaps3d()

• Fixes gaps between ends of 3d curves on adjacent edges myPrecision is used to detect the gaps.

Return type:bool

FixLacking()

• Applies FixLacking(num) to all edges in the wire Connection between first and last edges is treated only if flag ClosedMode is True If <force> is False (default), test for connectness is done with precision of vertex between edges, else it is done with minimal value of vertex tolerance and Analyzer.Precision().

FixSeam()

• Fixes a seam edge A Seam edge has two pcurves, one for forward. one for reversed The forward pcurve must be set as first //! NOTE that correct order of pcurves in the seam edge depends on its orientation (i.e., on orientation of the wire, method of exploration of edges etc.). Since wire represented by the ShapeExtend_WireData is always forward (orientation is accounted by edges), it will work correct if: 1. Wire created from ShapeExtend_WireData with methods ShapeExtend_WireData::Wire..() is added into the FORWARD face (orientation can be applied later) 2. Wire is extracted from the face with orientation not composed with orientation of the face

Parameters:num (int) – Return type:bool

FixSelfIntersection()

• Applies FixSelfIntersectingEdge(num) and FixIntersectingEdges(num) to all edges in the wire and FixIntersectingEdges(num1, num2) for all pairs num1 and num2 such that num2 >= num1 + 2 and removes wrong edges if any

Return type:bool

FixShifted()

• Fixes edges which have pcurves shifted by whole parameter range on the closed surface (the case may occur if pcurve of edge was computed by projecting 3d curve, which goes along the seam). It compares each two consequent edges and tries to connect them if distance between ends is near to range of the surface. It also can detect and fix the case if all pcurves are connected, but lie out of parametric bounds of the surface. In addition to FixShifted from ShapeFix_Wire, more sophisticated check of degenerate points is performed, and special cases like sphere given by two meridians are treated.

Return type:bool

FixSmall()

• Applies FixSmall(num) to all edges in the wire

Parameters:

• lockvtx (bool) –
• precsmall (float) – default value is 0.0

Return type:

int

• Fixes Null Length Edge to be removed If an Edge has Null Length (regarding preci, or <precsmall> - what is smaller), it should be removed It can be with no problem if its two vertices are the same Else, if lockvtx is False, it is removed and its end vertex is put on the preceeding edge But if lockvtx is True, this edge must be kept ...

GetHandle()

GetModeDropSmallEdges()

ShapeFix_Wireframe_GetModeDropSmallEdges(ShapeFix_Wireframe self) -> Standard_Boolean

LimitAngle()

• Get limit angle for merging edges.

Return type:float

Load()

• Loads a shape, resets statuses

Parameters:shape (TopoDS_Shape &) – Return type:None

MergeSmallEdges()

• 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.

• theLimitAngle (float) – default value is -1

Return type:

bool
