Sheetmetal offset face question??

[Anonymous]

I need a face exactly 2 in offset from another face, but I need the one side of the face cut at an angle. I'll post the part so y'all can see it. The problem is that in order to do this so it will unfold the right distance away I use a plane 2" offset and sketch the new face and then select bend and the two edges, inventor puts a flat or straight edge on both edges. How can I do this without just making a flat face and estimating/ guessing how much to leave for the bends to come out right? That is how I made this part. Jerry
