For a proposal, I need to 3D-print a scale model of our winged vehicle design. But the foils/wings do not print completely because they are too thin when scaled down. They are also extremely weak when printed. Seems like the Thicken feature should help, but it's grayed out. The wings are solids, not surfaces - is this my problem? Is there a way to convert solids to surfaces? Is there another feature that will do what I want?
I could edit the sketches that the wings are lofted from, increasing all Y dimensions, but this seems like a cumbersome approach.
