Summary	0000700: Part->Feature->Mirroring needs boolean operation
Description	Hi, IMHO after creating a Mirroring Feature, some kind of boolean operation is required to fuse the result (e.g. a union when mirroring a pad, and the "common material" of both shapes when mirroring a pocket). For example, inserting the following code in FeatureMirroring.cpp seems to give OK results for mirroring pads: BRepBuilderAPI_Transform mkTrf(shape, mat); // ----- inserted BRepAlgoAPI_Fuse mkFuse(mkTrf, shape); if (!mkFuse.IsDone()) return new App::DocumentObjectExecReturn("Fusion with mirrored shape failed"); // TODO: This is copied from Feature.cpp from here ---- if (mkFuse.Shape().IsNull()) Standard_Failure::Raise("Shape is null"); TopoDS_Shape solRes; TopExp_Explorer xp; xp.Init(mkFuse.Shape(),TopAbs_SOLID); for (;xp.More(); xp.Next()) { solRes = xp.Current(); } // to here ---- if (solRes.IsNull()) return new App::DocumentObjectExecReturn("Resulting shape is not a solid"); this->Shape.setValue(solRes); //this->Shape.setValue(mkTrf.Shape()); // ------- end inserted return App::DocumentObject::StdReturn; I am willing to work on fixing this if someone confirms that it is the right way to go. Jan BTW, product version 0.13 is missing from this Tracker, so I used 0.12 instead
