: If this is the case, probably you can make a blend (I can not remember but : there is an option for doing not parallel sections) : I agree with using a blend. Copy the iges section with 'use edge' for the first blend section. Save this as a .sec file. Reuse this saved section for the second section ('Sketch>Data from File'). It is placed with drag, scale and rotate handles so that you can position it anyway you want. If you wish the trajectory curved, do a smooth blend, three sections, placing them in relation to each other to achieve a curved leading edge. I think this is what pitosYflautas referred to when he mentioned the rotational blend (vs. the usual parallel blend) which can also achieve the curved leading edge.
