| Summary | 0032859: BRepLib_FindSurface not return an expect plane | ||||
| Description | there are two bugs : > bug1: we expect plane's dx is [1, 0, 0], but return [0, 1, 0], After analyse I find that the return normal is [0, 2.4790833534415498e-33,1], it should be [0, 0, 1] we can use newell's method to calc the normal > bug2: The wire is made by Steps to reproduce the problem, then invoke the BRepLib_FindSurface function, it returns plan1. After serialize and deserialize the wire, the BRepLib_FindSurface function return plane2. plane1 and plane2 are different. After anylise I find deserialize has changed the first Edge's data, I think deserialize should not change the input data[wire.brep] > this isuee fix the first bug | ||||
| Steps To Reproduce | gp_Pnt pt0(-500, 25, -6); gp_Pnt pt1(-450, -25, -6); gp_Pnt pt2(450, -25, -6); gp_Pnt pt3(500, 25, -6); BRepBuilderAPI_MakeVertex v0(pt0); TopoDS_Vertex vertex0 = v0.Vertex(); BRepBuilderAPI_MakeVertex v1(pt1); TopoDS_Vertex vertex1 = v1.Vertex(); BRepBuilderAPI_MakeVertex v2(pt2); TopoDS_Vertex vertex2 = v2.Vertex(); BRepBuilderAPI_MakeVertex v3(pt3); TopoDS_Vertex vertex3 = v3.Vertex(); BRepBuilderAPI_MakeEdge e0(vertex0, vertex1); TopoDS_Edge edge0 = e0.Edge(); BRepBuilderAPI_MakeEdge e1(vertex1, vertex2); TopoDS_Edge edge1 = e1.Edge(); BRepBuilderAPI_MakeEdge e2(vertex2, vertex3); TopoDS_Edge edge2 = e2.Edge(); BRepBuilderAPI_MakeEdge e3(vertex3, vertex0); TopoDS_Edge edge3 = e3.Edge(); BRepBuilderAPI_MakeWire w0(edge0, edge1, edge2, edge3); TopoDS_Wire wire = w0.Wire(); BRepLib_FindSurface findPlane(wire); Handle(Geom_Surface) plane = findPlane.Surface(); | ||||

@Manycore, you everywhere in this bug use the word "excepted" (synonym "excluded"). Did you mean "expected" ("anticipated")? |

|
@msv , sorry, it is a spelling error. I means "expected" |
