Besides working out computations by hand, what software can be used to determine fillet and cul-de-sac profiles. Can site-works (Microstation) be used?
SiteWorks ? That pretty old software you have there! You are going to need InRoads to output your transition control lines from your surfaces and then use the "fillet features" command. There is also a cul-de-sac alignment generator so you can generate a horiz. alignment then a profile.
