Description
Civil 3D, now in its second (2006) release, is an object-based system that maintains relationships between all of its design entities, so objects such as road alignments, surface models, and building pads have built-in intelligence so they know how to interact with each other. The result is a dynamic design environment, meaning that any changes made to one part of the design will be automatically propagated throughout the entire project. Move a road alignment, for example, and any related elements such as profiles, cross sections, and volumes are updated automatically on the fly. This not only enables engineers to make design changes efficiently (without having to rework individual lines, circles, and arcs) but helps ensure the overall accuracy of the model and all of its project data.
