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

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
