I need to make a flat path from this curved shape.
Can anyone give a helping hand?
Well, in SW the file you attached is completely useless as far as editing goes. Ok. Here's an example how to create it and the result.
Hope this helps.
Attachmentshow to cut and unfold.SLDPRT, 301 KB
To get an oval shape, use multiple sketched bends. Prepare an additional drawing to calculate the line positions of the sketched bend and the required radii... More complex, but it will work just like the basic example.
I attached the file. The dimensions you may not like, but the point is you can use the attached part file to go back step by step.
Now I looked deeper. The bend is a circle with a fixed radius, I have a oval which doesnt work for me, for some reason.
how is it possible :D
I tried that.
I asked. I will answer too.
You can't make a sheet-metal part from oval sketch. It has to be a straight line or a circle - only then you can make it in sheet metal and flatten it.
At least I didn't find any other way.
Try with the attached file (part) SW2010 and try replicating the steps, let me know if you understand the procedure. There are other ways as well, this was the simpler way to explain.
PS. For laser cutting, you will need to do an additional drawing and an additional cut that goes through the radial section under 90 degrees or to do the drawing on the unfolded sheet. Depends on what you want or need.
Brian has the correst solution for sheetmetal
Using sheetmetal loft and normal cuts
This part will flatten
When doing loft increase # of bend lines for better display
Good solution Brian
This has a direct application to something I had to work on, which was developing cut patterns for Pontoon Boats.
