Good Morning,
Just a quick confirmation please, We are a fabrication company however this particular job requires 2 No 90 Deg elbows to suit Dia. 800mm ducting. Because the bends are not available we intend to "roll" 4mm plate to suit the elbow as a facetted unit.
However my concern is we need to supply our profilers with the correct flat pattern for us to roll. Therefore can someone confirm the dimensions/conclusion I have attached are correct?
Thanks in advance,
Alan Stewart

Solved by Kent1Cooper. Go to Solution.
I don't believe they are:
I think [without analyzing too deeply] that the shape of the edges will be a form of a sine curve.
Kent,
Thanks for coming back to me. This is what I was concerned about and unfortunately I don't have modelling skills/capabilities to try it and see how it turns out.
I'm awaiting a response from a local engineering workshop for a response as they will model it in Inventor or similar.
Thanks,
Alan
I followed the link in post 4, 90° bend, generated the lisp file, copied it and loaded in 2020, had the flat pattern in a matter of less than a second. Very nice.

If something I wrote can be interpreted two ways, and one of the ways makes you sad or angry, I meant the other one.
GP, I don't see the post (#4?) you're referencing here. Can you supply this link? This flat pattern generating lisp file sounds pretty cool. Thanks in advance.
