I am trying to extrude a panel from a sketch that contains parts of bodies but also empty space. When I try and select the area to extrude I am unable to select the middle empty space. and am only left with the part of the sketch that overlaps the body. If I were to offset a plane from the surface and sketch on that I would be able to select the full space, but that doesnt work in this situation. Is there something I am missing that will let me select the full space?
you might want to double check to make sure your sketch is completely closes at the ends or maybe a overlapping line. If it is completely closed it should showed shaded light blue
