    This would require a blend, but even if you can easily put them on the
    model, are you sure you want to do that to the mold maker?

    Perhaps the largest radius that would fit at the top would be the most
    cost effective solution.

    You can, it'll be tough to do, and will take some time.

    Since the thickness varies the draft, the rounds you want to create will
    have to be of a variable radius, (am I seeing it right?). If such is
    the case I would start constructing some datum curves at the ends of
    where the rounds are going to be going and start "wireframing" some
    entities to used to drive surfaces. Get the surfaces in, and start
    working out how to make cuts, or solids, and go from there...

    This is just a simple guess as to how to do it, yes it can be done but,
    it will take some experimenting to find a reasonable method to do it, I
    don't think it is a quick click away.

    So... the question begs... do you really need a true full round? It
    looks like the ribs are supporting a boss, a simple constant round
    through the area may be good enough (just make it small to start, and
    tweak up in size until it is as close to a full round as permissible).
    You could try a variable radius round and even get closer by allowing
    the radius to increase linearly along the edge.

    Not true ,you should be able to pick both edges and do a full round just
    like straight walls.  Not sure about the sequence of clicks in WF2, but
    I've does it with 2001.  In fact, if you add a large enough round on the
    two cross edges in between, you can create a full round that will run
    from the top of the rib all the way to the bottom, transitioning across
    the other rounds.

    As a former mold designer, I suspect your mold maker won't care as he's
    going to either CNC the cavity or CNC the EDAM electrode that will burn
    the cavity.  Either way, the computer does all the math.  If this is the
    worst problem the mold maker has to deal with in your part, he'll be
    ecstatic.
