we have an organic shape we are making a 2-part mold for. We need a dividing line/surface created which allows us to make the 2 sides of the mold to open without having any cut backs, or negative tapering that would prevent the mold opening, or would break the item. The cut line/dividing line won't be a straight line, or plane, and if it was I would nor need any help in getting this done. So we would need to figure out the line to split the item, and also add some bosses/holes that help to fit the sides the both sides exactly and tightly.
