I'm trying to develop the sheet metal flat pattern for the attached part but cannot get the tangent arc for the 22" radius to pick up the intersection of 2 lines. Something must not be sketched properly. For my top profile, I'm sure its correct but for the elevation offset lines to layout the arc, I cannot get the tangent arc drawn. I offset lines from the edges of plate using "convert entities" and the lines are there but the intersect of the 2 lines isn't available to pick from. I've attached the hand sketch of what I need. Once I have the curve at the 22" radius, I believe I can use extruded cut to get the finished part. Thanks in advance for any help.
