Thanks for the replies. In the scenario below, depending on the scale of
the
change, we would either save the part as a new revision (ge; 100-01-B) or
as
a new part (eg; 100-02). Drawings that had used the rev 100-01-A part
would
remain unchanged and new projects could use either part as required as
they
would be uniquely identified.
What I'm trying to get my engineer away from is calling a part
"ProjectA-100-01-A" and then on the next project calling the same part
"ProjectB-100-01-A" because I feel that this means we can't tell from the
part name whether the 2 are really identical. What I want him to do is
simply call the part "100-01-A" and on the drawing refer to it as such.
Identification of the project should be a separate unrelated entity on the
drawing template.
He however insists that ISO9000 explicitly states the the name of the part
should contain the project reference. We're not actually ISO9000
registered
but do want and try to follow the guidelines where we can.
