Convert of formed piece of round bar into sheet metal in order to generate flat pattern cut length?

Hello,

Is it possible to convert of simple formed piece of steel round stock into sheet metal so that a flat pattern can be generated?  For example, I have a simple piece of 3/8" round bar that I have formed at 90 degrees.  How could this be converted to sheet metal, maybe not even possible?  I didn't use the structural member profile as I didn't see one available for solid round bar.  I used the Swept Boss Base.  Any suggestions?  I've attached the .sldprt as well as snipped image on screen.  Thanks!
