Standard_EXPORT | BRepOffsetAPI_FindContigousEdges (const Standard_Real tolerance=1.0e-06, const Standard_Boolean option=Standard_True) |
Initializes an algorithm for identifying contiguous edges on shapes with tolerance as the tolerance of contiguity (defaulted to 1.0e-6). This tolerance value is used to determine whether two edges or sections of edges are coincident. Use the function Add to define the shapes to be checked. Set option to false. This argument (defaulted to true) will serve in subsequent software releases for performing an analysis of degenerated shapes. . | |
Standard_EXPORT void | Init (const Standard_Real tolerance, const Standard_Boolean option) |
Initializes this algorithm for identifying contiguous edges on shapes using the tolerance of contiguity tolerance. This tolerance value is used to determine whether two edges or sections of edges are coincident. Use the function Add to define the shapes to be checked. Sets <option> to false. . | |
Standard_EXPORT void | Add (const TopoDS_Shape &shape) |
Adds the shape shape to the list of shapes to be checked by this algorithm. Once all the shapes to be checked have been added, use the function Perform to find the contiguous edges and the function ContigousEdge to return these edges. . | |
Standard_EXPORT void | Perform () |
Finds coincident parts of edges of two or more shapes added to this algorithm and breaks down these edges into contiguous and non-contiguous sections on copies of the initial shapes. The function ContigousEdge returns contiguous edges. The function Modified can be used to return modified copies of the initial shapes where one or more edges were broken down into contiguous and non-contiguous sections. Warning This function must be used once all the shapes to be checked have been added. It is not possible to add further shapes subsequently and then to repeat the call to Perform. . | |
Standard_EXPORT Standard_Integer | NbEdges () const |
Gives the number of edges (free edges + contigous edges + multiple edge) . | |
Standard_EXPORT Standard_Integer | NbContigousEdges () const |
Returns the number of contiguous edges found by the function Perform on the shapes added to this algorithm. . | |
Standard_EXPORT const TopoDS_Edge & | ContigousEdge (const Standard_Integer index) const |
Returns the contiguous edge of index index found by the function Perform on the shapes added to this algorithm. Exceptions Standard_OutOfRange if: - index is less than 1, or - index is greater than the number of contiguous edges found by the function Perform on the shapes added to this algorithm. . | |
Standard_EXPORT const TopTools_ListOfShape & | ContigousEdgeCouple (const Standard_Integer index) const |
Returns a list of edges coincident with the contiguous edge of index index found by the function Perform. There are as many edges in the list as there are faces adjacent to this contiguous edge. Exceptions Standard_OutOfRange if: - index is less than 1, or - index is greater than the number of contiguous edges found by the function Perform on the shapes added to this algorithm. . | |
Standard_EXPORT const TopoDS_Edge & | SectionToBoundary (const TopoDS_Edge §ion) const |
Returns the edge on the initial shape, of which the modified copy contains the edge section. section is coincident with a contiguous edge found by the function Perform. Use the function ContigousEdgeCouple to obtain a valid section. This information is useful for verification purposes, since it provides a means of determining the surface to which the contiguous edge belongs. Exceptions Standard_NoSuchObject if section is not coincident with a contiguous edge. Use the function ContigousEdgeCouple to obtain a valid section. . | |
Standard_EXPORT Standard_Integer | NbDegeneratedShapes () const |
Gives the number of degenerated shapes . | |
Standard_EXPORT const TopoDS_Shape & | DegeneratedShape (const Standard_Integer index) const |
Gives a degenerated shape . | |
Standard_EXPORT Standard_Boolean | IsDegenerated (const TopoDS_Shape &shape) const |
Indicates if a input shape is degenerated . | |
Standard_EXPORT Standard_Boolean | IsModified (const TopoDS_Shape &shape) const |
Returns true if the copy of the initial shape shape was modified by the function Perform (i.e. if one or more of its edges was broken down into contiguous and non-contiguous sections). Warning Returns false if shape is not one of the initial shapes added to this algorithm. . | |
Standard_EXPORT const TopoDS_Shape & | Modified (const TopoDS_Shape &shape) const |
Gives a modifieded shape Raises NoSuchObject if shape has not been modified . | |
Standard_EXPORT void | Dump () const |
Dump properties of resulting shape. . | |
