Subject: RE:
[plcs-dex] Representing parts - Issue: RBN-11
My
motivation for writing the comment was that I want to represent the fact
that a version of a part follows on the previous version.
Initially this has
nothing to do with an assembly of parts - it is just about the
part.
Similarly if a Part
is derived from another part, I want to relate the two. Again, this has
nothing to do with an assembly. Hence my suggestion that these
representations should be in the rep_part capability.
Regards
Rob

[plcs-dex] Representing parts - Issue: RBN-11
In the interest of visibility My
response & comments to the issue are provided below;
RBN-11 by Rob
Bodington (05-02-21) minor_technical issue
The relationship between
different version(s) should be described in this capability, not
"representing_assembly_structure" (C003). The product_version_relationship
should be treated in the same way as in representing product as individual,
and use the same classification. I propose: Derived_version_relationship
Sequential_version_relationship Hierarchical_version_relationship as defined
in the PDM Schema usage guide.
TJT
Response: Relationships between parts,
part versions and view_definitions are not currently described within
Representing_parts. They are described within
representing_assembly_structures as these relationships are used to define
the assembly structures and how those structures might change if different
versions of a part are used. However, it is possible to include
product_version_relationship in this capability, but it would then exist in
both. This is because supplied_part_relationship (a subtype) would & I
believe should, stay within C003. Though I could be
persauded.
I agree with the use of the
classification and the ref data derived from the PDM schema.
Comments?
regards,
Tim
