Hi everyone, I`ve been fighting for a while to model this from a single sheet cut with lots of bendings afterwards.
But couldn't make it...
Does anyone ever model this or have any ideas? It need to be manufactured, so it's not only 3D model I need the flat pattern...
interesting question. I am not experienced with sheet metal, but I would start with the design straight forward and than use the "convert to sheet metal tool". I've added a quick tryout to this post.
Hey thanks for your reply!
The thing is usually this pieces have a curve along those long parts on the side.
I will try to use yours as start and then add some loft bend or something like that...
I thought that it might be a simpler way, because it's actually a big bend radius...
I'm pretty sure this version could not be replicated in a single piece like you show the first version. As J. Mather points out these are very different animals.
Even if you eliminated the obvious overlaps in this design I think getting the leading edge hem combined with the first design might be impossible or REALLY expensive.
Isn't that a photo of real part?

Yes it is, but it's not made from a single bent up part like the first model appears to be. It's made from a bunch of individual parts riveted together.
I was assuming, maybe incorrectly so, that the point of the first design was to reduce parts and assembly cost by making the entire upper finned structure out of one piece as shown.
I can see the difference between the images (I pointed this out in my original post).
I was referring to the first image - looks like a studio photo of real world to me.
Maybe it is just good CG.
I think the first image can be done.
You have shown two very different designs (in terms of modeling).
Which one do you want? The first one or the second one.
Can you Attach the *.sldprt of your initial attempt here?
What version of SolidWorks are you using?
2nd one seems simple because making bits and pieces and assembling. 1st is the challenging one. What do you think?
Hi sorry, the idea is to do something as first picture, only posted the second one to show that there is a curve on the "blades".
Sorry for the misunderstanding....
I'm using sw 2018.
As soon as I get back to the studio will post my file... I didn't want to post it to not influence the way you guys could think the modelling...
But it was a plain drawing and then tried to sketch the bendings, but couldn't make it with such big radius... Only playing with bend allowance was starting to look alike, but I think it wasn't the right way....
Is your first image of real part?
Do you manufacture these?
If not, can you provide link to company who does make them (save us a bit of research time)?
Do you have image of real world Flat Pattern?
I suspect that there is no material removal other than the kerf to cut the curves in the Flat Pattern.
Is this a school project, or is this a work project?
Heres something quick
I think you nail this!
Can you provide me how you did the bend? If file much better...
I spent a few hours last night trying....
Nothing fancy about it
Never heard of it
Hello Teemu,.. it's a classic yet different sci-fi fantasy movie... it's release was overshadowed by a lot of high profile films...it's definitely worth watching!
No wonder I haven't heard of it, it was before my time! But I'll be sure to check it out.
This upper portion seems dome, is it possible to bring it in the sheet metal?
Probably, with a form tool.
Edit:
I think the important question is what are the tools you plan to use to make this? I dont think that could be made without some custom tool and die to support the material. Can you shoot a pic of the tools used to make the one piece?
First one can be cut and form by hand.
Bend the fins down and twist them for the spiral.
Second is stamped.
