    Hello,

    I have a few doubts about occurrences management.

    At page 117 of the document SSDE_User_Documentation_V2-2 it is indicated a diagram that shows how occurrences are not modeled but generated by the tool. I am not sure, however, if this is supposed to be an automated generation or not. For example: in the StarTracker model I want to create a fourth ElementUsage StarTracker, and consequently I should have a fourth ElementOccurrence StarTracker with its Electronics and Head EO. However, I still have to create manually these occurrences. Is it correct or am I doing something wrong?

    The second doubt is related to property values propagation. It works fine from Definition to Usage levels, but I don’t understand how it works from Definition level to Occurrence level.
    I will make an example to clarify. I define for the ElementDefinition StarTracker a mass property, which is correctly propagated and indicated in the ElementUsage Star Tracker. When I select an ElementOccurrence StarTracker, this property is not indicated in the QUDV values tab, but if I try to choose the Category Mass it tells me “the ValueProperty is already defined in ElementDefinition”. Why can’t I see it then in the values of the Occurrence?

    Thanks for any help,
    Paolo

    Hi Paolo,

    concerning the first question: Occurrences are not generated automatically, you need to trigger the generation by running the respective command where you can either create a new occurrence tree or re-generate into an existing occurrence tree. This regenerate is basically a merge, i.e. modifications you had made on the existing tree (like adding a new property you only have/need on the occurrence level) will be preserved.

    concerning the second question: re-generating the occurrence tree after you had added a property on ElementDefinition Startracker will put that property (and value) into all occurrences of StarTracker, provided you activated “Propagate Value Propeerties…” in the occurrence generation dialog.
