editing the datagroup catalog

i have checked and this question was previously asked but not entirely sure about the answer

i want to go through the datagroup catalog for specific catalogs such as st.gobain: ensign & timesaver, victaulic and other mpipe types to include all the options for their fittings

  • when i go to the datagroup catalog editor, instances are listed but do not give the manufacturer type
  • i would like to create a full set of manufacturers fittings for a full range of pipework & ductwork types

my question is

  • if i was to add new catalog instances for manufacturer fittings, how do i protect that work from being overwritten on subsequent software updates
  • if i create new fittings for an entirely new manufacturer name would those fitings work together? ie if i place a pipe/duct using new catalog manufacturer, would the program find bends etc also added to the datagroup automatically?
  • if all that worked can i copy out the datagroup and use in other places of work? (if i change projecty or job)

  • Hi David,

    Keep in mind that DataGroup catalogs specify component types; e.g., Elbow, Wye, Tee, etc. organized by the applicable discipline.   The manufacturer's catalogs are stored in Access databases (*.mdb) under the dataset's \DataGroupCatalogs\xxx_Lib folders.   For example, \Plumbing_Lib, \Fittings_Lib, etc..   They are then tied together using XML mapping files as outlined in this wiki: https://communities.bentley.com/products/building/building_analysis___design/w/building_analysis_and_design__wiki/10910/creating-a-custom-manufacturer-s-catalog-for-plumbing-components



  • Steve,

    having looked into the catalogs by reviewing them using excel, the information looked quite extensive. in reality the plumbing package does not place fittings from the same catalog as the pipe. Trying to edit the pipe fitting to find the catalog doesn't work either, as it will not accept a like catalog.

    having come to the conclusion that Bentleys fittings don't join together catalog to catalog, trying to create catalogs using an access database & XML mapping files seems pointless.

    I have placed a service request at the end of last year over this and not had any satisfactory replies. When i went back to review the request it had disappeared, it seems like all trace of my request has been deleted.

    I am in the process of creating a catalog of fittings graphically as a workaround but this is going to take a long time

    Accuracy is very important and it looks like the only way to get that it to assume all the pipe fittings in bentleys 'catalogs' are only an interpretation of the actual fittings.

    As BIM expects more from the model and the claims from the software vendors get ever more ahead of the reality the only way to meet clients expectations it to try and take ownership of the problem by creation libraries if pipe fittings and manually placing them into the model. (also ductwork and electrical fittings)

  • Hi David,

    I think (or hope) the missing SR issue may have been resolved as outlined in your other thread.

    Regarding pipe vs. fitting sizing, if you've provided specific examples in that SR then I'd imagine it should be enough for support to do some testing.
