Measuring Manga on 18th Century Spanish Ships (width at gun deck)

[Jeffrey Modell]

1) Great work.
2) What CAD program do you use? How do you get the parchment paper background?
3) I have been closely reading Steel's Vade Mecum on drawing ship plans. Without the plates/drawings, it is pretty difficult to understand (the online copies and reprints skip the plates) the compass work. Might buy Stallkart - Steel's originals are unaffordable.
4) Same problem with jpg size you had. Would it be possible for you to email the dxf/jpg you want me to use?
5) FYI, I was originally researching Murciano for a small kit maker in Eastern Europe (no $ compensation, just personal satisfaction and a copy of the kit to me to inspect -- it's a hobby), but he has become backlogged so the odds of this being more than my personal scratch build have declined. If a kit ever goes forward of Murciano, is it ok if I base the hull at least in part on your work? Happy to be sure a credit to you goes in, but that's as far as I can go. If not, I will try to use same methods on Murciano myself.
6) Regardless, I still want to learn how to do this kind of work. When I read about the creation of the Le Flueron bow by Jean Boudriot, it seems to me a useful and fun skill.

Thanks Again!

Personally, I use Rhino, which has several predefined workspace display modes, either more technical or more artistic and visual in nature, and this set also includes the Artistic mode (that with a ‘parchment’ background, but one can specify other, individually selected background as well).

You don't need to do so. Admittedly, some time ago, back in the analogue era, I even invested quite a lot of money to purchase all these textbooks in hard copy format. Unfortunately, the size of the plates is too large for home scanning, or it would indeed require a troublesome and costly order in a specialist printing company. Either way, Steel's Vade-mecum only has two rather ‘poor’ plates (in terms of its content), and it's not even worth bothering with them (incidentally, this is why the Vade-mecum could originally be much more affordable for less affluent buyers than its complete version, i.e. Naval Architecture, from the same year). Much more numerous, containing incomparably more information, and in this sense more attractive, are the plates from other works. And they are available online: those from Steel's Naval Architecture via Abraham Rees' The Cyclopaedia, 1820. And some plates from Stalkartt are available online from the Danish museum archive. All are of very good or good enough quality.

4) Same problem with jpg size you had. Would it be possible for you to email the dxf/jpg you want me to use?

Yes, of course, I can send you everything that has been done so far, including in CAD format, but in this case I need some time to prepare the project for such transfer and direct use by someone else (than me). Fell free to use it in any way you like.

6) Regardless, I still want to learn how to do this kind of work. When I read about the creation of the Le Flueron bow by Jean Boudriot, it seems to me a useful and fun skill.

Well, I think it is fair to say that almost no one is much interested in what is happening below the waterline (in terms of shape). For almost everyone, it is enough that there is nothing there that would offend even absolute laymen in these matters, i.e. something that one could almost physically trip over, such as a protruding piece of a cannon barrel or a tiller. In this context, large investments of time and money in such matters may indeed be seen as a rather unnecessary undertaking. You have been warned .

Apart from that, to be on the safe side, it can also be pointed out that the ancient design methods and the subsequent effective lofting of those difficult surfaces are actually two separate issues and skills. And, obviously, obtaining the correct surfaces through lofting is not possible without a previously prepared, correctly drawn up design. Unless, of course, someone is satisfied with just ‘whatever’.

It would probably be less work to just send a single file (and no pdfs). I use Fusion360: *.f3d, *.3mf, *.ipt etc. Not sure which one of those is a project file other than *.f3d. If that works for you. And thank-you ever so much.
