What sort of anomaly is this showing?
Should we file a ticket.

Seems that the HLR does not work properly on this model. It shows a hidden line from the radius seam from the back view. The right view have the issue as well.

would that be considered a occ bug?

To hide this line, select it, enable the Change Appearance of Lines tool and set Visible to False.

Well sure that is a workaround. But, it shouldn't be required.

If It is a occ issue, then we have little choice but to do workarounds. And maybe document it.

I've seen this before, but haven't detected a pattern. IIRC it is always with smooth lines.
