Autodesk’s AutoCAD Civil 3D is a dynamic, model-based, civil engineering tool that allows you to increase
productivity and accuracy in all aspects of your design. When you design in Civil 3D with the intelligent object
tools, you are actually working in a fully-functioning, 3D environment. You can create dynamic, threedimensional
models of existing conditions, roads and railways, site grading, and even pipe networks, all based
on intelligent design objects. Proposed 3D models can be compared to and combined with the models of
existing conditions to calculate cut and fill volumes and generate models of the overall proposed design. Since
the environment is dynamic and the objects are intelligent, a change to one object causes an update of all
related objects, labels, and tables, erasing time spent on manual updates and greatly improving accuracy.
