Summary0031466: Cannot import layers from STeP file (7.4.0 regression)
DescriptionImporting the attached file with 7.3.0 results in two layers, with some geometry on one and some on the other.
7.4.0 still imports the two layers, but any call to XCAFDoc_LayerTool->GetLayers() on any shape comes up empty. Similar ways to retrieve the layer the geometry lies on fail in a similar way.
Additional information
and documentation updates
The regression seems to come from the changes to XCAFDoc_ShapeTool::FindShape (XCAFDoc_ShapeTool.cxx:291), probably from the following commit:

    0030727: Data Exchange - Problems in Shape Tool

    Add protection from return of not top-level shape by FindShape method.
    Add protection against located roots into FindMainShape method.
    Add new Draw command for FindMainShape.
    Add flag findInstance to Draw command FindShape
TagsNo tags attached.
