I'm trying to extrude the rectangle in Sketch 1 up to the surface but get geometry errors.  I've tried extruding to surface, extruding to body, and extruding past the surface and using the surface as a trim tool.  I've repaired the surface to ensure there are no gaps in the geometry and it seems like there's a sort of overhang which causes Solidworks to hiccup.  Is there a way I could repair the surface to fix this or find a different way to extrude from the rectangle to the surface?

Thanks for the help
