Thanks Derek, yes I'm using the design criteria, but the retaining wall not shown in my cross sections, I have entered the width, top profile and bottom profile, but it didn't work for me, I think my problem in how to define the top and bottom profile of my retaining wall. only I need in my design cross sections to show something represent my Steel railing at the bridge design, I also tried to find a design criteria for a curb, so I can modify the curb easy to change height of the curb to 3.5' and width to be 10" to match my railing data, but I couldn't find a criteria for the curb, now I'm reading the text book of how write a criteria in one of Ray's links, is very interesting and useful . Regards,
