Sheetmetal...Bending over an existing bend.. Can you fold a paper airplane in onshape?

Tom_20

Can a bend be bent over again resulting in 4X thickness?   Can a simple paper airplane be created as a sheetmetal part or any other way?

I am not sure exactly what shape you are trying to get to. The only way I know to get Onshape to do what you asking is using surfaces. If you use tangent arcs in sketching Onshape sheet metal tools will convert those as rolled surfaces. If you are trying to make multiple folds come to a point (like a lot of the paper airplanes I folded when I was a boy) and still have a flat pattern, that might be a challenge.

If you were to make a hole where the material would be distorted at the corner, you might be able to model something that sort of makes sense in sheetmetal, but it's not really designed to model materials which stretch like paper and are very thin like paper.

There is an online origami simulator that treats a sheet of material as infinitely thin and somewhat stretchable.

Are you looking for this type of shape. Done with surface and thicken. This is a non-sheetmeatl part. Created with surface and thicken.

here is a version that is sheet-metal with a flat pattern for each step

For the flat patterns you will need to make them based off the design intent, but with a few tools it can be done
