hi everyone...new to forum and hopefully someone can helpmeout!

i received an IGES file that contains a series of splinesthatcreate a surface. i opened the 3d sketch to edit and assumedicould just offset the splines to create a new surface buttheoffset icon is off. i already tried just offsetting thesurfaces,but it had gaps and wasn't happy w/ the results.

any suggestions on offsetting the splines in a 3dsketch?
