What's new:
New and improved features AutoCAD Civil 3D allows designers infrastructure more effectively work on projects of transportation facilities, land and water resources. AutoCAD Civil 3D 2012 includes improved tools for working with tracks that help organizations to design in accordance with established standards. Optimized procedures for editing corridors, and thanks to improvements made by means of data import model objects have become more intelligent.

New features:
Enhanced with corridors
Editing corridors simplified with regard to the visual presentation of the plans, longitudinal and transverse profiles. Additional flexibility modeling process gives the possibility of creating cross-sections for several baselines (eg, for roads with a dividing strip), as well as on an inclined axis sections.
Improved layout of the tracks
Improved support for multi-element has become curves, added the possibility of dependency management for roads, including those imported from LandXML. Now, more accurately it assigns labels to the points of intersection and mid points of the curves.
Manage Styles
In AutoCAD Civil 3D adds several features that make more effective joint work of experts and help organizations to design in accordance with established standards. We mention only a few new features of the product:
- Copy of styles and settings from the selected design or pattern;
- Improved control over the copied styles;
- Cleaning of drawing styles that are no longer needed;
- Replacement of the styles of objects in the drawing.

Improved data import
The process of creating intelligent objects in AutoCAD Civil 3D simplified. It makes it easier to select, view and import data geotochkah. Intelligent 3D-pipeline network formed on the basis of data with GIS format.
Integration with Autodesk Vault Collaboration AEC
Autodesk Vault Collaboration AEC, integrated into AutoCAD Civil 3D, provides a reliable and safe management of design data, saving not only the current, but the previous version of the project. Procedures for data replication allows the product is used on projects both local and global scale. Control functions provide the ability to track the progress of the project and, if need arises, to roll back to its previous state. Now users of Civil 3D can be placed in the general store items such as geotochki, terrain, alignments, profiles and pipe systems. The effectiveness of production of technical documentation provided by the addition of file storage of drawing sheets.
The software-Autodesk Vault Collaboration AEC purchased separately.

AutoCAD WS
Add-in allows users to AutoCAD WS running on mobile devices and web browsers, view, edit and transfer to colleagues drawings in format DWG , trained in the software products based on AutoCAD (including in AutoCAD Civil 3D). This means that work with drawings and show them you can now, regardless of the environment. Drawings made in the family of products AutoCAD, and related files are stored in an online workspace with a simple and convenient access. View and edit drawings made through the browser, Apple iPad, iPhone or iPod touch. With AutoCAD WS engineers working on infrastructure projects, may introduce colleagues, customers and contractors with projects of the general plan, sketches of engineering structures and construction documentation.

Design:

Dynamic bill of materials and the calculation of the volume of excavation
Information about purchased products can be directly imported into AutoCAD Civil 3D objects to assign the value of the drawing. The automatic calculation of the amount of materials, and reporting on them, which can be exported to Autodesk Quantity Takeoff or in formats supported products AASHTO Trnsport.
Possibility of calculating the movement of earth mass and volume of earthworks can supply plan, the number and placement of materials during construction. When you make changes to the draft AutoCAD Civil 3D creates a chart moving earth mass needed in the calculation of earthwork.

Intelligent layout of the pipelines:
System of sanitary and storm sewer are based on the rules. Pipes and wells are edited using a graphic, and manual input, and for them there is also a function to check the intersections. The product allows you to build the final drawings in terms of pipeline networks, the profiles and cross sections. Members have shared access to information about the pipeline networks, such as marks, size, grade or type of external payment applications or integrated into AutoCAD Civil 3D Extensions Hydraflow.

Alignments and profiles:
Flexible layout geometry can create alignments and profiles with simultaneous control of the standards.

Modeling Corridors:
When creating 3D-models of transportation facilities, land and water uses objects AutoCAD Civil 3D: alignments, profiles, surfaces, and intellectual standard sections, etc. Due to the visual interaction provides efficient creation and editing of corridors.

Conventional and circular intersections:
Dynamic 2D-and 3D-models of intersections created by the Wizard, which forms the roadway, structures and corridors. Roundabout Layout function helps speed the design and editing of parametric 2D-circular cross-roads, including road marking in accordance with the standards.

Geospatial Analysis:

A comprehensive mapping information is the key to the proper planning of project works. Built-in AutoCAD Civil 3D mapping features allow you to query spatial data, create thematic maps, perform buffer, tracing and analysis of overlaps.
Surveying:

Coordinate Systems
Supports more than 4000 real coordinate systems provide an accurate representation of design data.
Support for GPS-navigators
3D-model of the project is exported to LandXML format for use in GPS-navigators.
Database of Surveying
Expansion Survey Link Extension, bundled with AutoCAD Civil 3D, you can easily receive and process data from field journals, transforming them into a format Autodesk. FBK. The use of field journals greatly simplifies the design. Expansion Survey Link Extension supports most of the input data format of field journals.
AutoCAD Civil 3D provides a complete toolkit for creating baselines. Critical transition areas in the design of building sites, topographical survey and reconstruction of roads are described by survey figures. The figures are imported, created and modified during the design process, the import figures can enter information about elevation, which may be useful in calculating the amount of earth masses. Adding to the topographic and planimetric product features allows experts surveying services more effectively interact with engineers.
