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.
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.
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.
