Bend a body along a path ?

Hello everyone, i'm beginner here, and i want to modelise a 3D thing , i've been training using tutorials online, for 2 weeks now and i managed to get a simple "thing" into Fusion 360 using few sketches and basic operation using bodies patch and all that stuff.

However i want to bend a body along a path, I dont know if there is any way to do this ? Maybe is just a design problem ? 

I cant figure out how to shape the thing to look like what i want to obtain. 

I tried to recreate an object using 3 pictures of the object along the Axis planes as canevas . Could you please advice me or help me about that design i joined ?

there isn't a bend modifier in fusion. (there are interesting bend operations you can do in sheetmetal, but that's not really the right workflow here).  generally in fusion you make things the way they are shaped.  you don't bend a shape after it's made.

attached is an example of using simple overbuilt swept surfaces to define the volume for the object. 

the directions the reference pics are taken to each other isn't orthographic, so they will be a little difficult to use as a reference, but this is a start.

Wow, thanks for your ultra short reply, very interesting technique :  I didn't this would be possible using only sweep and boundary fill command nice technique . You told me about pictures, they were taken using my smatphone but I took other and mluch better pictures today using DSLR camera and a ruler laying under the object, this way I can fully calibrate canevas with precision .

I marked your reply as a solution because it helped me a lot and i learned something new today . Eventually do you see any other methods to achieve modeling using pictures ?

the picture quality is fine, using a higher end camera isn't going to make a lot of differance.  it's the andle of the photos to each other that is important.  (having a ruler in th eshoe mit be nice though, I would place it at the middle of the object.)

 

it would be nice if all the shots where at right angles to each other (or maybe they are, it's hard to tell).  separate/top  and back/front photos also.  along with additional detail photos at differnt angles to see what's going on (well, you probably have the thing in your hand, which is even better than photos)

 

just realize that there will always be some distortion in photos, so final dimensions have to be determined with

actual measurements.

 

I think the primary surfaces are mostly swept, and not some kind of fancier loft, again hard to tell with out the object in my hand.  You can further refine the shape by cutting the edges back and lofting together the corners instead of using the fillet command.  lofting corners can be tricky.

 here's a fun video of that type of technique.  i like this guys presentation style, wish he would do more-
