hello guys , I could really do with help here .. I am an aerospace engineering student and currently am working on wing design project .. and i found out when I extrude a particular aerofoil using solid extrude (extrude boss/base) the model does not follow the curve as good as a surface extrude, surface extrudes are better to follow my aerofoil curve is there a reason why this happens? .. do solid boss follow different mathematical method than surface extrude ? what kind of methods used in solidworks ? ..
