      Hi, Sean!

      I'd be grateful if you could share how did you model the hull surface (via loft and cross sections of the hull, via rails or however else) because I'm about to modell a hull with spray rails and i dunna how to manage this ;/ usually I use cross sections and loft, but this ^*&^(*& spray rails are worrying me...

      Regards,

      Kuba

      Hello...
      As fantastic as Rhino 3.0 is - I myself do not know how to 'constrain' a curve to a surface - strakes are the last thing I do after I am happy with the hull bottom...
      I also do not trust cutting out an ISO curve...
      I still like projecting diagonals to same - just make sure you use the X axis as a control and your diagonals extend past the transom bottom...
      If that makes sense - remember - I know nothing about boats - nothing - I am a professional figure skater - however - it does not look like I will make the upcoming Olympics...:)
      Question - are you using Rhino - I can post files - just not these ones...:)

      hahahha ;) Of course you know nothin' bout boats- I'm the best NA at last ;). I hope that you'll practise your skiing more and participate in upcoming Olympic games with a T'shirt with ,,Boat- Design.net" ;)

      Now seriously:

      yes, I'm using Rhino v 4

      As I started to modell this hull ( a catamaran 9 meter long motorboat for fishing purposes) and began to modell the sprays, i figured out that the guy who designed the hull ( because I'm there only to style the deck) modelled it in such a way: he made a constant cross section, placed it at the stern and then selected 2 rails and made a surface :)

      (At least I've done it that way and the created hull looks the same as on the photograph he gave to me XD)

      Only thing i can say is LOL.

      Once again thanks for your support,

      Regards,

      Kuba

      2500 cans? Yeah kinda ,,make our dreams com true" XD

      instead of playing with pencil and ruler and those sophisticated formulaes that nobody who actually HAS friends understand- let's play with some metal and earn nearly the same ;)
