I have problem to transfer this part from surfacing to sheet metal
I do not know how to flat it
Maybe somebody of You can do it with explanation please
You can create a lofted bend feature using Sketch2 and 3DSketch1. It is not true that you can't use a 3D sketch for a lofted bend feature. You can't use your 3D sketch, but you can fix it so it works. Just edit the 3D sketch, right click on one of the sketch elements and select chain, then use the Fit Spline tool in the Spline Tools menu. Don't use any guide curves in the lofted bend, because you can't, and it doesn't need them for what you're doing. The result flattens out.
By the way, stop using the Fixed constraint for everything, it's not helping you out.
I used fix only for this example
This was created in assy and all sketches was "stolen" I broked refs just for this
I try to create part the way Y described
