hey guys i have two curves(curves 46 and 47) and two guide curves(curves 48 and 3d sketch 7) and i want to boundary surface using them but solidworks doesnt do it and i dont know why it doesnt give any messages
heres the file
You are too ambitious. You want to do way to much with just one surface.
I get the message "... self-intersecting geometry". Probably because the curvature in Curve48 is propagated into the complex curves towards the front.
I would divide this area into at least 5 separate surface features - most likely more.
