Thank you David for clarifying, I guess I am referring to shelling (though other platforms I've worked on have not differentiated between the two). However, though Visose makes a good point with regards to a polysurface object, if I were to take an irregular curved surface and offset it a certain amount I would not expect it to intersect with itself as many examples I've been working with (I can post soon if you'd like). On a related note, when I created a control curve to be used in lofting / extruding / etc. and then offset the curve a certain amount I find that it too begins to overlap and intersect itself, hence creating a convoluted surface when applied within a component chain. I understand what the offset component is doing, but it seems that there needs to be a way to offset a curve and a surface without being so literal, in that every point on the surface must be copied and moved a fixed distance regardless of how distorted the result becomes. Perhaps the shelling of V5 will address this, yet it still seems that more intuitive offsetting of curves should be possible without the possibility of shelling.
