Hi All,

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.

intersections of lines do not automatically make an endpoint for you to select, or snap to. you can sketch the arc a little out of place and then add the intersection relation manually afterward, or add to coincindent relations. BTW, the radius will not be 22"
