Pushing the sheet metal envelope....

Can anyone advise a way to convert this to a sheet metal part so I can unfold it. It's a custom fire vase for a public space. We will be fabricating from 14ga stainless steel. It will have an open top and a closed bottome (with holes). I know I'm pushing the envelope here but feel compelled to ask.

    Hi @kent_henderson - sheet metal can only unfold flat and cylindrical surfaces, so your twisted loft shape cannot be converted. How is this intended to be manufactured? That might give you an idea of how best to model it.

    It will be laser cut from 14ga stainless sheet in 4 sections and a bottom, then the 4 sides will be rolled and welded in each corner.

    Getting that sort of flat shape is difficult and subjective. Each manufacturzing process will differ. Try ExactFlat from the AppStore- that will get you the closest.

    I would love to be able to do things like this. We're always pushing sheet metal unfold to the limits, and then some. Inventor will not do this either.

    Thanks Neil. I'll give ExactShape a try.

    I really think there is room for un-uniform unfolding tools. However, it may not be easy to get consistent unfolds. Similar problems here.

    I'd love to hear how you get on with ExactFlat. My experience wasn't great when I tried but that was a few years ago to it may have improved since then. 

    This IR sort of relates. https://forum.onshape.com/discussion/9764/flatten-unwrap-surface#latest
