    do you have an image of what you are trying to bend? Are you roll a sheet into a cylinder? If that is the case have you tried creating the cylinder first then unbending it to make it flat?

    You can select the bend option use one of the edges you want to bend and then specify a 360 degree bend and use the inside circumfrence as the bend radius. Its probably not the best way to create the part but it should work. Of course this could be dependent on what version of Proe/Creo you are running. It may not be this simple in older versions of Wildfire.

    The problem is that you cannot simply mate the ends and let the bend radius be determined by the software. And a quick calculation also won't yield perfect mating because of the deformation (stretch and crush) of the metal. To calculate the full finished diameter, you will have to add the bend allowance factors into the calculations. I haven't done it but it should be possible to write that into relations.

    One thing I learned not long ago about sheetmetal; you can make a surface model and then thicken it. You will end up with a very similar, if not the same geometry.

    But for this; in sheetmetal, I would revolve the first surface. Apply a seam; unbend it; add the holes; and bend back.
