In a great show of filling the voids left by the software, the folks at CAD Apps Australia have release Stringer Connect as a free utility for converting various DC files to Autodesk Fieldbook files. This tool is a subset of their Stringer design program which also runs on C3D.
Check out their site, www.civil3dtools.com, for a good collection of great add-ons, including the most comprehensive intersection package out there, Advanced Road Design. If you haven’t seen the demo, I highly recommend it.
Thanks Jon, Peter, and the rest of the CAD Apps team.
