Thanks Scott! you tha man! I am used to laying it out by hand with paralell line development, tried doing it in the computer and started pulling my hair out.Much easier for me to it the old school way. I just wanted to make a drawing of my rearend so i could mess with different truss designs.Ok this has been bothering me, but I figured it out. You want to do a lofted sheetmetal bend. I made this one by making a parallel offset plane, with a bigger dia arc on the lower level, and a cmaller dia arc on the upper level. The click on 'lofted bend', pick the two arcs, and specify the thickness. That makes a sheetmetal cone that will flatten on command. You could also put one end of the arcs on a centerline with an angle dimension for more control.
