    Problem creating a parametric array

    Hello everyone, can someone help me??
    I am trying to create a parametric array of pales in a fence panel where the standard panel has post ctrs of 3.0m, posts at 60mm wide, rail 2940mm long. The pales are centered at 129mm with an equal end pitch of 115.5mm. What I am trying to achieve is when the post ctrs reduce the quantity of pales reduces accordingly either with the end pitches remaining at 115.5 or reducing accordingly at each end. Obviously should the post ctrs reduce by increments of 129mm then the end pitches would remain at 115.5mm.

    I attach my model and would really appreciate a bit of help - my model was created in LT 2020

    Many many thanks in advance!

    If I understand you correctly the 129 will always remain 129 and the 115.5 can change according the the length of the fence?

    Hello Robin,

    Thanks for getting back.

    Yes the 129mm dimension has to remain constant and the 115.5 end dimension can change. Ideally if possible I would like to keep a fixed 115.5 dim at one end so that in real terms if an installer needed to cut a panel he would do it at one end only but it's not 100% required.

    Regards,

    Jack

    OK did some testing and this seems to work. It has a few more parameters for various calculations and I changed the names to something simple so I can type in everything faster. This does change the outside dims to the same one every time. So 129 for all the middle dims and I added a formula that looks if the dims at the end are larger then 115 and if so it adds and extra post.

    Doesn't appear correct. Can you make the default 'L' 3000mm post ctrs? If you can the pale spacings along the rail would be:

    1st pitch-115.5
    21 pitches @ 129mm=2709
    Last pitch (to rail end - 115.5)
