      Can somebody tell me how to create a deck below the level of the gunwale. The design I am working on has a sunken foredeck and another break in the deck level at the cockpit bulkhead.
      Also, I cannot get the lines plan to show the buttocks or waterlines etc. I have tried entering numbers in the “intersections” box but in the display options the icons remain grey and when I reopen the inersection box nothing has been saved. What am I doing wrong?

      Regarding The buttocks and waterlines, in the layers menu there is a box where you can choose weather show the intersections in the model and in the linesplan, check there is probable that those check boxes are not “checked”.

      Regarding the first question “deck”, english is not my primary language therfore and don’t fully understand what you mean, maybe if you explain me a little bit more i can help, sorry about that

      Thanks Karma
      I have designed a hull and now I want to create a deck below the top edge of the hull but I do not understand how to do it since I can only have two faces from any edge. is that clearer?
      I will experiment with the check-box, thanks for the suggestion.

      I have the waterlines now thankyou. The check box was part of the problem,another was that I was entering the intervals in meter not mm.
      Still stuck with the deck.

      Hi nkottler,
      is your sheer at the same level from stem to stern
      if so, hightlight the lines between the control points from stem to where you want it to stop, use the extrude under Edit–> Point extrude upwards vertical, that will give your a raised poop deck or if you just want a raised bulwalk you will have to extrude across the thinkness of your hull material and then extrude down to your old deck level then extrude all your deck to the centre line or use the new deck tool.

      Sorry,
      its Edit –>Edge–>Extrude, I only just got up, need coffee.

      Thanks Mike
      I have managed to draw in the deck. Is there a way to extrude parallel to a surface?

      Other option is model your gunwale has a box, very thin so it won’t affect your hidrostatics, there is a model in the models database where somebody did something like that the model name is Freeship demo 1 , check it and probably you will understand what i mean.

      Hello Mike
      I made the deck by extruding the hull top sideways 20mm (hull thickness)in then 250mm down to create the gunwale then sideways to the centreline.
      Take two examples: If I had a cylinder and wanted to create a cylinder wall thickness using this teqnique the sideways extrusion would not work as the wall would go from full on one quarter to nothing on the next.
      As the second example, when I extruded the edge down, some of the points had gone through the hull surface and all of them had to be manually placed to get the correct hull thickness. My question was whether it is possible to do this type of extrusion to follow another surface.
      Sorry this is quite a long explanation..
      Nick.

      Nick,

      I made the deck by extruding the hull top sideways 20mm (hull thickness)in then 250mm down to create the gunwale then sideways to the centreline.

      (Yep thats the correct way to do it.)

      Take two examples: If I had a cylinder and wanted to create a cylinder wall thickness using this teqnique the sideways extrusion would not work as the wall would go from full on one quarter to nothing on the next.

      (Make 2 cylinders one sightly smaller inside the other. In layer Properties just give the outer cylinder cubic tonnage and wall thickness. You MIGHT be able to join the 2 cylinders with a face so there are no leak points at the end, I dont know myself, Ive sealed the end of a single walled cylinder with a face.)

      As the second example, when I extruded the edge down, some of the points had gone through the hull surface and all of them had to be manually placed to get the correct hull thickness.

      ( Thats normal)

      My question was whether it is possible to do this type of extrusion to follow another surface.)

      (No I dont think you can, not in Delft.)
