I am experiencing a problem with butt welds, they became black in colour and above all the relative edge preparation seems impossible to delete or edit. If I erase the relative welding, it still remains there with the same impossibility to be edited or deleted.
(same issue happened in the past with other types of welding).
in the lowest left corner, a message appears suggesting to use weld/edge preparation menu, but in the welding application, an edge prep. edit function seems to be absent (I didn't find it, it is only for defining new ones).
Anyone has an idea of where is the problem or has already encoutered this?
