Autodesk Civil 3D started out to establish a change in the civil engineering paradigm. First get the model and, most importantly, the data behind that model right. For practical purposes that word right means - suitable. From that suitable model we may automatically publish what we need to deliver in many forms.

We can make the annotation of Complex Corridors in Autodesk Civil 3D faster, better, and more consistent. A Complex Corridor is one of those Multiple Baseline beasties (or beauties) that can model our design solutions more effectively.
Autodesk invests seriously on improving the Civil 3D Corridor engine’s capabilities. Today, Civil 3D users to can grade…

We’ve discussed the topic of Data References (DREF) in Autodesk Civil 3D and the important Object Model challenges we simply have to deal with in our Civil 3D projects. This DREF chatter spawns a bunch of questions about Civil 3D Surfaces, Surface DREFs, and how to make them work better and faster. The existing and design surface discussion takes a few words and…
