Summary0033517: Incorrect boolean intersection (BRepAlgoAPI_Common)
DescriptionComputing the intersection between the following two breps (former.brep and single.brep) using BRepAlgoAPI_Common returns an empty intersection.

Slightly translating the shape in single.brep (e.g. by 1e-4 along the x-axis) leads to the expected result (i.e. a non-empty intersection).
Steps To ReproduceLoad former.brep and single.brep and apply BRepAlgoAPI_Common on the top-level TopoDS_Solids.
TagsNo tags attached.

Could somebody have a look? I've just tested with OCCT 7.8.0 and the issue is still present.
