Bending a flat pattern surface

Bending a flat pattern surface

I have a flat pattern surface for an edge for a piece of furniture. The flat pattern is to be bent so it forms a circle, but also at an angle. I've looked into the sheet metal features, but I haven't figured out a way to do it. Furthermore I've also tried with the Flex feature, but it's hard to control. The ends should not meet but have a distance of 60mm, and the pattern should be bend 75 degrees from ground. In theory, this should not be hard to do, but in practice... I have attached my SolidWorks file as well as a picture of the bent part

Hope you can help

RE: Bending a flat pattern surface

Solidworks does not handle that kind of bend well. You can get a cylindrical ring no problem
but the conical profile will not be able to be unbent. If you want to just have a guess at what
size piece to cut out prior to forming you could take a flat pattern for a cylindrical ring with
a diameter the same size as the middle of your conical ring as a good first shot. It will likely
need a little trial and error to get it just right. How are you forming the parts?

RE: Bending a flat pattern surface

@hendersdc, yeah that was my conclusion as well after trying most of the day yesterday. It is actually a ring edge for a table, so it is made from plywood and bent by hand. It is mostly for our PDM system, where it would be nice to have both.

@SBaugh, thank you very much for help. You're right, it is not exactly what I want, but more along the lines.

I actually thought SolidWorks was able to do this sort of thing better.

RE: Bending a flat pattern surface

You should be able to unbend a cone in Solidworks. This piece would just be a slice from a cone.

You are judged not by what you know, but by what you can do.

RE: Bending a flat pattern surface

@berkshire, yeah I think I managed to do it with a cone. But still that does not help me, does it?

RE: Bending a flat pattern surface


I'm not sure if i'm missing something but its quite easy to end up with a sheet metal part that will make a pattern such as your example. You can't go from flat to bent for a cone to my knowledge but doing a cone and then getting a pattern is fine. Very easy. See attached example file. NOTE: its not exactly to your size specs s i've just slapped it together and got it close.
