Adding a deck to model

[Adrian]

Hi. I’ve started working on DELFTship quite short time ago and I have question. How can I add deck to model?! Please help me!

P.S Sorry for possible mistakes i don’t know english very well 😛

1. Read the software’s manual. :dry:
2. Understand it. :whistle:
3. Create a new layer (call it “Deck” 😉 )
4. Extrude the top edge of the hull toward the symetry plane.

There is an Icon in the “EDGE” menu, that looks like a face sligthly folded, that icon creates a deck with a small angle (deadrise)…

Select edges on the shear line and on the “edge edit options” and click “Extrude curved”. 🙂

Kind regards, Hrvoje

Although the usage of the “Extrude Curved” function on the boundary edge of the sheer line is the recommended way to construct a deck,
according to the DS Manual as well as to the majority of expert users who have replied,
I do find it rather restricting and seldom appropriate, at least for my intentions.
The biggest drawback of the “Extrude Curved” function in my opinion is that it only works on boundary edges,
which means that such a deck can only be applied as a kind of lid on the hull.
But real ships have several decks. So what about an elevated forecastle or a poop deck as opposed to the main deck?
Another reason why I find the “Extrude Curved” function often of little value at least for the construction of decks,
(mind you, “Extrude curved” can be better and quicker applied for construction of stern transoms than using the common “Extrude Edge” function for this particular purpose)
is that it interrupts the fairness of a bulwark or gunwale.
Instead you would have to patch a bulwark (layer) on top of an “Extrude Curved” generated deck and thus would lose C2-continuity of the spline patches (i.e. no equal values of 1st and 2nd derivatives on the boundary nodes of hull sheer line an bulwark’s baseline).
Therefore I usually prefer constructing decks by using the “Find Intersection of two Layers” function on a beforehand newly created horizontal layer (with depth, i.e. Z-coordinate, of the deck to be constructed) which I created with the “Add Box” function with the coordinates of the diagonally opposing boundary points chosen in such a way that the new flat “Box” layer would extend a little beyond the length and half beam of the hull.
This method is admittedly a little bit more cumbersome but it avoids the loss of continuity for bulwarks or any other part of the hull’s shell that extends above the sheer line.
