    I am trying to loft cut away to leave a wall thickness on a part.

    I can loft cut the Inside out no problem, but I cannot figure out for the life of me how to loft cut outside the shape. I tried putting some arbitrary rectangles on my two sketches and then loft cut the void, no dice. So I am here for some advice.

    Thanks?

    Why don't you just loft extrude the outer profile, then loft cut the inner profile as you have already done, rather than starting with a solid block? Use an angled reference plane to create the reference plane for the upper sloping face. If it's to sit protruding from a rectangular plate, do that first.

    I would just use a Loft then Shell it to the thickness you need. In this case I deleted the base Extrude feature and the Loft Cut. I then created a Loft Boss with the original Loft sketch then Shelled it to the outside with the two end faces removed.
    With this you can add any additional features you need.

    that seems like a approach that makes sense, I thought of that on my drive home also.

    thanks!
