Non-prismatic Variation Direction[X-Y-Z]: The user only needs to input this value if they want to define nonprismatic variation. If the user intends to define nonprismatic variation, this input is optional. The nonprismatic variation direction X should be used for sections assigned to elements following the alignment in the longitudinal direction, such as girders. The Y direction should be used for sections assigned to elements in the transverse direction, such as pier caps, and the Z direction should be used for elements in the vertical direction, such as pier columns.
