[Anonymous]

Hi, I'm trying to loft a hull design with both fore and aft with sharp edges. I'm using loft command in patch environment but it don't work. What do I do wrong? /Martin

How do I insert a public URL?

Can you File>Export your *.f3d file to your local drive and then Attach it here to a Reply?

screen shot would be useful 😉

Hi,

Thanks. Here is the file.

Hi again. Thanks for instruction how to attach a file. Here you have the file where I'm trying to loft the hull around the spline lines. If I use a flat aft i can loft but it seems like when I want sharp edge of the aft I don't get it to work. How come?

Loft in Fusion is unlike loft in surface modelers it somewhat can do many things at once - meaning they implemented function from

multiple tools into one.

So regarding your boat you cannot loft it because loft needs either

1. profiles that are apart from each other to skin a surface through them like a band

2. profiles where the ends touch each other so we we can make surface like a sphere or umbrella

Here is a quick screen cast to show you what does not and what set of profiles work

traditionally for boat design you can also use vertical profiles and loft rail them

at around 3:30 he starts going into lofting. This tutorial helped me learn loft.

Are you trying to do something like this?

[WHolzwarth]

Hmm. I wanted to try it with Inventor.

But none of F360 export capabilities seems to be able for export of sketch geometry.

Is it fact, or am I missing something?

[Anonymous]

That's funny.  This is a technique I developed in Inventor and this is my first Fusion part.

I can post an ipt.  What version of Inventor?

[WHolzwarth]

Your file is an easy task, Richard.

Type3 v2.f3d is the challenge

[Anonymous]

My bad.

I should have paid attention to who's message you were replying.

[WHolzwarth]

No big deal, Richard.

Kudo for your excuse.

LOL

Actually, what I was trying to achieve by posting my file was to discern the design intent from the original poster.  Do the rails he shows represent the keel, chine and sheer of a hard chine hull?  If so, perhaps my approach could work.

Hi rhinterhoeller. No, this is not what i´m struggling with. The challenge is to loft a hull with sharp ends in both front and aft of the boat.

[Anonymous]

Hi, It does represent the keel, chine and sheer of a hard chine hull but the difference to your hull is the shape in aft.

Hi Martin,

Could you please attach at least one screenshot of what you want to do for more understanding

Thanks Claas! This works fine=) I must have missed to add a new profile by press + sign...

no worries - you did not miss anything.

currently the loft code sometimes has still issues with selecting profiles as new edges and not joining them.

i had the same problem till I figured out why loft did not want to work
