Attached are some lines of as ship, From these we have to make a plate geometry with which the plate can be bent manually with bending machine to get a curved shaped plate as per attached dwg and image. with autocad, solidworks or inventor etc
Use the 'LOFT' command . Pick each line in sequence.
This will only create a flat plate with no thickness.
Offset the lines first, join each end and convert them into 'Regions' then 'Loft' them to make a solid.
