    Default Parametric Arrays & Nested Families Tutorial

    Upon request from other users i've create a tutorial on using nested families to create parametric arrays.

    Difficulty: Intermediate

    Let me know if its helpful...

    Cheers!

    Note: As beegee mentioned the final formula for the no of louvres should read

    Heigth /(Free Air + Louvre Height) and not width as shown. - THIS HAS NOW BEEN AMENDED

    Please note this has now been updated and is available from my blog

    Good work Mr. S.

    ( Just check the formula for number of louvres - I think it should read " Height / ( Free Air + Louvre Height ) ... not Width ? ) Your height and width dimensions are the same in the tutorial.

    So it should...! Thanks. I whipped it up pretty quick and was mainly concentrating on making sure i had all the right screen captures. When i was actually creating the family for the tutorial. I'll have to amend it when i get a chance...!

    Cheers.

    Okay, so i'm pretty proud of this one. I wanted to test out the ability of arrays and nested families so i've created a double nested family to create a multi bay louvred panel window that will calculate the no of mullions needed given a maximum span for the louvres.

    Cheers,

    Chris.

    EDIT: Just updated the file with an amended version as there were a couple of things i had to fix...

    Just wanted to say thanks Chris for the tutorial. I couldnt get one of my parametric arrays to work in the project so I looked this up again, and presto, it works. Thanks again.

    Following on from this discussion....I have a balustrade family I am trying to get parametric such that the glass panels are equal in size and I can specify end and centre gaps without exceeding a maximum panel size. I cannot for the life of me get the thing to work 100% correctly. I have attached the file. Please any help or guidance from the masters?

    For starters, try not to use instance parameters when nesting families... Always use type parameters and link these...

    Heres the fixed file.

    omg, thanks so much. I dont know what you did but it is awesome. What was I doing wrong? I see all the formulas are correct. Is it how I was locking the array?

    A master of paramtetric arrays are you!!!!
