sb correction with inversed openings

[MDHering]

In one of my models, the normales of space boundarie areas of openings were inverse relative to the corresponding wall space boundary. In my understanding, the function fix_surface_orientation should handle this issue of my model. However, this function did check if the wall orientation is correct and then did correct the wall with all corresponding openings. In this special case, the openings should not be turned.

I did attach the example .ifc file. Github doesn't allow .ifc files as attachements, therefore the file is saved as .txt.

My local workaround is changing lines 250 - 254 of file bim2sim/tasks/bps/sb_correction.py

# complement openings if parent holds openings
if bound.opening_bounds:
    op_bounds = bound.opening_bounds
    for op in op_bounds:
        op.bound_shape.Complement()

to

# complement openings if parent holds openings
if bound.opening_bounds:
    op_bounds = bound.opening_bounds
    for op in op_bounds:
        # only complement openings of face normal if needed
        if bound.bound_normal.Dot(op.bound_normal) < 0:
            op.bound_shape.Complement()

@veronikarichter could you have a look into this?
