[@Mcfryguy5555]

I feel your pain! Do some videos on sheetmetal manufacturing.

Did anyone ever figure out why the third example did not flatten?

[@ethanclsn2138]

I just experimented with it, and if you set the thickness to .01 and extend your trajectory line/sketch rip line past the edge of the cone it will flatten out properly

I draw the part as solid, then I convert it to sheet metal. The part flatten without any problem.
