    Line Based Family nested inside another line based family and arrayed

    Hello everybody!!
    I'm new to this forum and kinda new to Revit, I'm actually putting on line in Italian all of my progress with this program:
    Tecniche Parametriche di Progettazione
    this is the link if you are interested.
    The problem I'm not able to solve is about nesting a line based family inside another one

    I'm trying to build a brisesoleil panel that has the chance to grow in lenght
    Here are some snapshopt of the procedure


    This is the single wing inside the family

    07_Provvedo quindi ad allinearla sui bordi interni della mia cornice


    07Bis_Questo Ŕ il risultato ottenuto


    And as long as it is alone it flexes fine
    but when I do try to array it the family explodes..









    Any suggestion??

    Array are a bit of mind bend in Revit
    Best way that i have found is to create a Reference Plane on the Part at its Centre that is a Strong Reference (So you can align stuff to it)
    Then Load it into your Opening Family above
    Array it like normal, then using the align tool align it's Centre with the Centre of the Opening (You will need to add this Ref Plane into the Family above.
    This way it will array based on the Centre of the Family not its Ends.
    You may need to also assign the Length of the Part (Line Based Length) to a new parameter of your opening

    The CL alignment is a good idea, but I have run into similar breaking (though not with nested line-based-into-other-line-based) and found that once the 'break' happens, even though it should have worked, re aligning the pieces seemed to solve the situation. I outline the process to fix the issue that you may be experiencing something close to in the "kitchen Cabinets" part of: Fear and Loathing In a CAD vs. BIM World: Line Based Families 1: Kitchen Cabinets...OK, OK And a Trellis...

    -BTW an old post and I think I may have to revisit it using adaptive repeaters...

    Excellent suggestion. I tend to lock a nested family by it 'Defines Origin' references which stops 'breakage' most of the time.
    You can also add a reference line to your array, and dimension to the reference lines instead of the nested component. Not ideal yet a functional workaround.
