. Autodesk AutoCAD Civil 3D 2010 Update 3.1 | 3.3 GB AutoCAD Civil 3D - a solution for the design of infrastructure and documentation for them. Civil 3D is designed for engineers working on projects of transport facilities, land and water resources. Users are able to coordinate projects to explore design alternatives to simulate the process of the facilities, and produce high quality documentation. All this happens in a familiar software environment of AutoCAD. Key features: Geospatial analysis for conceptual design: The integration of raster and geospatial data helps make better decisions in the early stages of the project. To visualize the ecosystem project, you can retrieve the images and surface models from the service Google Earth ™, as well as from other sources. You can also import geospatial data, such as soil types, information on land use and environmental constraints, to quickly analyze the possible impact of various design alternatives. Surveying and coordinate system: Geodetic data processing capabilities are fully integrated into AutoCAD ® Civil 3D ® 2009. A wide range of tasks - import field book, the processing method of least squares, the task and the transformation of the coordinate system, editing of the shooting, the automatic creation of shapes and surfaces of shooting. This ensures that the composite design: points, shooting figures and surfaces can be used throughout the design process, which eliminates the need for manual conversion of coordinate systems and the transfer of data from geodetic applications in the application design. Introduction to the project survey data will automatically update your project items. Profiling and dynamic relationship: Models of complex surfaces in AutoCAD Civil 3D support dynamic connection with the initial data - contour characteristic lines, corridor models and objects profiling. Surface used as a basis for creating profiles, sections and corridors. Any changes to the initial data lead to the automatic renewal of surfaces and options that helps to save time and reduce errors. A set of tools for profiling allows you to simulate the surface for the projection profile of any type. Graphical and tabular management profiling are easy to use. Function profiling using dynamic models of the relationship between the corridors and routes / profiles. Information modeling of roads: Based on specific local design criteria can be performed quickly build dynamic plans and profiles. Defined in the criteria for dependence continue to operate and optimize routes - for example, per-element and on the tops of the corners. Simulation tools allow the creation of corridors intelligent model of roads and other linear objects. In modeling the corridors of different objects using custom components cross-section, known as structural elements. In describing the transitions in the corridors allowed the direct use of trails, survey figure, the characteristic lines and polylines AutoCAD. Function interactively build intersections allows you to create complex models of intersections of roads, which reflect all the changes in the project. Models corridors may be used when creating the design of surfaces, calculating the volume of earthworks, bill of materials, construction of cross sections and in other tasks.
