getting a nice curve for the hull of a model ship

Anonymous — Fri, 10 Feb 2017 07:32:51 GMT

So I have a frame layout (or I will have soon) of a model destroyer. Somehow I need to draw the curves of the hull skin to follow the frames but curve in between them. So I am looking for a method to get good curves. Something like the "create form" function but get it to touch the frames. is there a way to to do this? or some other method?

The keyword here is loft with rails. Th raise being splines.

you should try to avoid designing tthe geometry it the methods th boat is being built physically. Most folks I've seen here on the forum use way too many profiles when lofting a boat/ ship.

Hmm, OK, any videos on it I wonder.....no matter I will go look....This would seem to be a key thing for me to do, I know I will use it a lot.

Gooday Thing,

All depends on the final output you want...

I have done aircraft, seaplanes but not boats. There is a screecast for a scultped Coal Bunker ship, under "Most Helpful" section of the library.

I think the scuplt area would give cleanest result, I haven't got the experience with tweaking in the right place for the right result with sculpt.

Loft in Patch or solid, can be finicky, but its what I use.

what trippy said, ship models I have seen in here have a lot of detail frames that creates overheads that Fusion dislikes.

Can I siggest that you do half and mirror, I prefer to thicken surfaces, for a skin, as solid shells are not reliable.

Geometry for profiles and Rails MUST intersect with each other,

use Project Intersect exclusively on these intersections. (Should be said in capitals and bold)

Can give more detail by PM

I've never seen that library. Would you have a link ?

There is most recent or most helpful sort box.

that ship I mentioned is alway near the top of Most Helpful

I dont really have any good historic pictures, but I do have the frame plan which I can make into profiles.

I liked this as a video...I will have a play.

No worrie ,Pete,

Thing, take a look in that link I posted, there will be a ton of videos short to the point on Lofts, when you search there.

The link you mentioned, would not give you a fighting chance, as he has not created any Rails to guide the shape, due to the complications around these maritime shapes.

even search in this Forum will find models already done with Lofts.

"The keyword here is loft with rails. The raise being splines" Not having much luck finding a tutorial on how to do this just bits of clues.

So I found this, https://knowledge.autodesk.com/support/fusion-360/learn-explore/caas/screencast/Main/Details/6f35c323-2def-40b1-b468-444e0f605e3e.html but its just a snippet.

I am also having problems with the English. I take it what you mean is use splines to make multiple rails that the loft edge will then follow when its projected?

Lets forget ship hulls for a second, is there an good tutorial on doing this no matter the shape?

I think using these together might do....time to experiment I think

Gooday Thing Thing

I think this example is clear with a bit of added detail in the beginning, you may not need....

Certainly follow his method for rail and profiles.

Thanks that looks really good....I will have a go at this later today I hope. Right now I am doing the frames / profiles.
