Hi, yes I went through the the article and I found the location where it is happening. But I dont know why and how to solve it.

Hi @stupsi_fleckch, if I can drop my two cents, I would say the issue comes from you trying to import an stl file as your CAD. We usually advise users to avoid this as it creates issues such as these faces:

The best would be to reimport your geometry as Parasolid or STEP instead.
