    BIM Troublemaker: Noah's Loaf - Curtain Panel Goodness


    This step took some tenacity...But tenacity starts with "T" which stands for Trouble!


    First step is to do this with a curtain panel by pattern:













    If you don't know what it is, shame on you! Go read here:


    Au Bon Panel


    Thank you Bob-Man and Shaggy


    So with that panel pattern in my back pocket, i could go ahead and start screwing around with my base model from last time:





    For what became my first attempt (thought this would be easy), I started by picking the edges between each rib and hitting the CREATE FORM button.








    I did this several times to fill the whole boat





    And then divided the surface and applied the appropriate Curtain Panel Pattern:





    It looked okay at first blush, but upon closer inspection, the shell edges weren't squaring up right. Actually, they looked downright sloppy:







    I'd rather be accused of fastidiousness than having too much time on my hands...Semantic argument for sure....nonetheless i tried again.


    This time I took the "Tedious Brute Strength" approach. First off, i hosted a bunch of reference points along the shell profile:



    And repeated this process for all 3 profiles and it worked exactly as i wanted:




    Then I hosted a parameter driven rectangle on each reference point. CREATE FORM again and voila!






    It worked as expected,





    but 2 problems remained:
    1) All my lengths were now curved and i wanted straight segments, broken at each joint for scheduling and measurement
    2) It was a damn lot of work and i got bored


    Okay...Trial #3!


    Because I set up the original Curtain Panel Pattern using the correct point orientation, I realized i could do the whole shell in one shot. The trick was going to be to use DIVIDE BY INTERSECTION in order to control the break points:
















    My segments divide out properly. If i did some work with reporting parameters, I could get some cool data out of this. Implanting MODEL LINES in the curtain panel would give me a structural stick model too!





    The joints go straight through which i am not overly keen on, but i suppose if i wanted it perfect, i could take it into Rhino or ACAD and perform some additional boolean operations...






    yikes....what a day....
