openPLM for electronic cad
 unsolved

Hello, I am currently evaluating ppenPLM for electronic cad use in conjunction with kicad. I have a few implementation questions: 1- how do I create parts with multiple vendors? 2-in the BOM tab I can add parts, but there is no way to add the reference designator. 3- what is the recommended way to support alternates?

thanks, GG

    Hello,

    1- how do I create parts with multiple vendors?

    As you wrote hereafter, we should use some kind of alternate links between parts.

    Unfortunatly, it isn't implemented yet. It's on our roadmap. We have spec and we plan to work on it at the beginning of year 2012.

    If you have some very good arguments, please tell us, and, may be, we could change our priorities.

    ...

    2-in the BOM tab I can add parts, but there is no way to add the reference designator.

    Could you tell more about it ? What do you mean by "reference designator" ?

    ...

    3- what is the recommended way to support alternates?

    I'd recommend to wait for someone implement alternate link function.

    If you can't wait, for the moment, you can only play with the type, reference, revision, name or another attribute.

    Create a special type "Alternate". Hum ! I don't think it's convenient.

    I'd prefer playing with reference : Create a standard link between assembly/parent and a part/son and use some special reference which show it's an alternate.

    Last idea, play with Ord and Qty parameters when you create link but it should be some numbers not string.

    Thanks.

      Hello Philippe,

      thanks for the quick reply.

      regarding #2:

      usually PLM software tailored for electronic cad will have an extra field for every part in a BOM.

      This field is used to store the reference designator (i.e. C1, C2, R1, R2, etc..) for the parts. The reference designator specified where the part is to be assembled on the PCB.

      regarding #1 and #3:

      For multiple sources what I have seen in the past is an extra tab that replaces the bom/child (for single parts that have multiple vendors) where all the entries are considered equivalent.

      For alternates within a BOM/assembly, what I have seen is an "alternate quantity" field that, when used in conjunction with the reference designator can be used to identify alternate components.

      The solutions above are by no means the only or the best ones for the problems, just what I have seen in my experience with PLM tools.

      regarding priorities, for ecad use, in my opinion there are 2 absolutely necessary features:

      1- simple import/export of BOMs (it's very error prone to manually enter a bom with several hundreds components)

      2- implementation of parts with multiple vendors (most designs have a large number of "generic" parts that can be purchased from different manufacturers)

      thanks!

        Thank you for your feedback.

        I understand what you mean. This new field is not an extra field on the part but on extra field on the parent-child link and it's more difficult to implement. We'll think about it. If you want, you can create a ticket in order to keep tracability of your request.

        I have difficulties to imagine what you mean. Please, could you tell me more about it ?

        See attache an OpenOffice? presentation file with a BOM extract. Could you rework this file and give to us an overview of what you have in mind ?

        Agree and we plan an import function from csv file.

        OK

          Hello admin,

          I am looking also if OpenPLM is usable as system and need also #2 the reference designators into the BOM of a assembly. I was also looking for a BOM csv import from the PCB design programm Altium.

          Question When is OpenPLM 3.0 avaliable?

          Thanks Maurice

            Hello Maurice,

            For #2, it's implemented. See  http://wiki.openplm.org/docs/2.0/en/devel/bom.html at Reference Designator chapter for more details.

            For BOM csv import, I've implemented something similar for one customer but I can't transfer it in the open source version for the moment.

            For the moment, I have no short term plan for a new version because I'm focusing in working for customers.

            I'm thinking about a crowdsourced project for OpenPLM 3.0 ... What do you think about it ?

            Thanks -- Philippe
