Okay, I'm running into dead ends trying to make a sheet metal part that follows a curve, and twists just a few degrees. I've tried switching to part (where it is now), and no luck there either. I've started with my curve I want to follow, tried using sketches, thought that would be the key to make it work.
Suggestions? I'm using ST9 MP8 at the moment.
Hi there @Trikefreak,
This will not be a "typical" sheetmetal model, as it has double curvature......so I would suggest modelling it as a surface, then thicken it. Although, you will need to use blank body to get a flat pattern from it, due to the form.

I played with it a bit this morning. I was able to get something, be it right or wrong.
I started with the center arc that I wanted, and then a line at each end centered on that arc, at different angles. I then did 3D sketch of an arc to each end of the lines, and made it equal radius to the original arc. It might be close enough for what I need, seeing how I have to then cut it to a curved width that fits in the bow of the boat. I'll mess around with it some more this evening.
I didn't think lofted would work, if both ends weren't parallel to each other? I need a "part" that is rolled in an arc, and twists from one end to the other.
yea we quite often loft between a semicircle and 3 sides of a rectangle to create a "square to round" as we call it.
You have the option to leave it as a twist in the sheet metal, or in the lofted flange properties you can specify that the twist is e.g. 5 step folds and it will give you the fold lines to step fold on press brake.
Just a word of warning, the lofted flange feature can be tempermental if your using a relativly thick plate for a given twist, or twisting a lot over a short distance!
