    Question Transplanting changes from one model version to another

    We have the following situation (briefly):
    Soem time ago, we were provided with a version of a model and have carried out some work on parts of it, including the addition of growth/creep. We have now recieved an updated version of the "base" model and need to combine the changes in the two versions of the model.
    What's the best way of doing this? I'm concerned that the same things (e.g. contributing area surfaces) may have been changed in both models.

    If you have been using extensive data flags, then finding the changed sections and updating them won't be difficult at all. You can use SQL queries select the changed objects based on flags and then copy/paste the objects between the models. You should also run a Compare between the networks to see the extent of the differences between the two versions. If you haven't been using flags, then the Compare results will be your only option for manually fixing the changed objects.

    Hi Martin, Hannah Austin of Clear Environmental Consultants Ltd presented an excellent paper on this at the Spring WaPUG meeting in 2007.

    Details of how to apply changes using scenarios in InfoWorks ICM or check in / out in InfoWorks CS are described in the on-line help and can help with specific examples if necessary. One of the most useful methods is to compare two models and save the differences in a .csv file. Those differences can then be applied to other models.
