Hi,

I am looking for suggestions on how to model a rib or stiffener that stays normal to a curved surface.  Imagine a flat bar stiffener on edge inside a boat hull that twists to stay normal to the hull as it sweeps along the length.  Is there a feature or surface tool that allows specifying a surface to stay normal to?  Or do I need to create two paths the right distance apart on the 'hull' to guide a sweep?  If this is the case, is there a method to offset a curve on a surface by a constant amount?

Thanks,

Eric
