Too large a bend radius

2D plans Layout
1

Hi all

I am having a problem that I had not had before and I can't seem to solve it (2 days on it).

I have to make a rounded sheet that mounts on a hopper. 

The sheet has a starting radius of 864mm and an end radius of 226mm. The distance between planes where the rays have been created is 755 mm. I tried to do it by transition fold but nothing helps. 

The second radius is 524mm behind the X-axis from the center of the starting radius. and an offset and center points features a lateral offset of 116mm.

The file is attached if you ever have trouble understanding

I work on Solidworks 2015 SP3.0. I've really tried everything so if anyone knows the solution I'm all for it.

N.B: The piece must be made in crunching because I use the .dxf to do the plasma cutting and the tracing of the bend lines

Hello, maybe we reach the limits of the sheet metal module and we need to use a sweep or a smoothing...

I used this solution for my finished model. Thanks anyway for the idea.

But how can I get the model unfolded? In fact I use the .dxf that I import on another software to make the cutting and tracing program.

Have you tried to transform your finished piece (the one where you used a straightening) by transforming it into sheet metal and then unfolding it?

 

To do this, you go to your room, you click on "convert to sheet metal" (either the second icon in the task bar, or by insertion => sheet metal => convert to sheet metal) ... and all you have to do is unfold.

 

It doesn't always work, it's not very clean. But it has already gotten me out of several complex situations

Hello

Maybe this is because the sketches are 3D.

I created 2D sketches with an offset plane and the 'Transition Fold' function passes.

Does this meet your needs?

Kind regards

@jmsavoyat : Thank you very much for your help.

I didn't know that 3D sketches could cause this kind of problem.
