how do I go by doing this.?
the sheetmetal has to be "rolled" and the also it has to be a flat pattern..
your help is appreciated.
In this example I started with a sketch of the part in the formed state. Reference geometry was added to help define the radii and tolal height. I added a short straight section at the bottom so I could book-end a diagonal trim cut with Unfold and Fold steps.
By adjusting the BA I was able to get the flat pattern to match your posted image, although the system generated bend lines did not match.
