AutoCAD® Civil 3D® software is a Building Information Modeling (BIM) solution for civil engineering design and documentation. Civil 3D is built for civil engineers, drafters, designers, and technicians working on transportation, land development, and water projects. Stay coordinated and explore design options, analyze project performance, and deliver more consistent, higher-quality documentation—all within a familiar AutoCAD® software environment.

AutoCAD® Civil 3D® 2013 civil engineering software extends the value of your model with new workflows and productivity tools for civil infrastructure. With a focus on optimizing performance, the new features offer pressure pipe functionality, improved survey, base map creation, and new rail track design features. And, a host of transportation features have been enhanced, including corridor composition workflows, 3D navigation and interrogation, and surface boundary definition. Streamline your civil engineering projects with AutoCAD Civil 3D software.

What’s New
Pressure Networks
AutoCAD Civil 3D 2013 features pressure pipe modeling tools, enabling you to: create and distribute pipe; add fitting and appurtenance content; model pressure networks in 2D and 3D; and leverage 3D pressure networks for interference checking.
Streamline civil engineering projects with improved survey workflows.

Survey
AutoCAD Civil 3D 2013 features a number of new capabilities that streamline survey workflows for civil engineering projects resulting in greater flexibility. You can query survey data for the creation of Civil 3D surfaces, point groups, and drafted survey figures. Usability improvements enable you to label survey figures, label between two graphical points, and control linetype display.

Transportation
Beyond a variety of scalability and performance improvements for civil engineering projects, AutoCAD Civil 3D 2013 offers a streamlined workflow for creating corridor models. Enhancements include usability improvements for creating and editing corridor assemblies and the inclusion of Autodesk® Subassembly Composer for AutoCAD® Civil 3D®. Additionally, AutoCAD Civil 3D 2013 extends alignment and corridor modeling capabilities to include rail-specific design and analysis capabilities. These include rail cant, rail alignment "type", chord-based alignments, and rail subassembly content.
