you should be able to accomplish quite a lot with that combination as far as signage goes. id upgrade to the bobart pro X if you dont have that. It gives you all sorts of options with the edge profiles of your sign elements. convex, concave, flat different edge options like radius, elliptical, straigh taper etc. you can also choose the way to different surfaces will interact with each other, for example defining a small concave part that overlaps a larger convex area. the icons are a little cryptic at times but once you understand them its ok. you should also be able to do all your 2d layout and design in the cad portion of bobcad as well. good luck with it.
