Autodesk® AutoCAD® 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. Streamline your civil engineering projects with AutoCAD Civil 3D software.
One Model. One Change. Multiple Updates. All Automatic.
Building information modeling (BIM) is an integrated process for exploring a project’s key physical and functional characteristics digitally—before it’s built. AutoCAD Civil 3D software is Autodesk’s building information modeling solution for civil engineering. The software creates coordinated, data-rich models that enable you to conduct analysis from the earliest stages of design; better visualize and simulate real-world appearance, performance, and cost; and document designs more accurately.
AutoCAD Civil 3D produces a single model, with intelligent and dynamic data, enabling you to more quickly make a design change at any stage of the process. Make better-informed decisions and choose design alternatives based on analytical and performance results. More quickly and efficiently produce visualizations that remain in sync with design changes as they are made. The model automatically reflects any changes to drafting and annotation throughout the project.
AutoCAD® Civil 3D® software enables you to deliver higher-quality transportation, land development, and environmental engineering projects faster. The software’s purpose-built tools support building information modeling (BIM) processes and help reduce the time it takes to design, analyze, and implement changes. The result is that you can evaluate more what-if scenarios and optimize project performance. Civil 3D software’s tools for surveying and design help streamline project workflows by automating time-consuming tasks.
Surfaces, Grading and Dynamic Relationships
With Civil 3D, you can build surfaces from traditional survey data, such as points and breaklines. Utilize large data sets from aerial photogrammetry, laser scanning, and digital elevation models by taking advantage of the surface reduction tools. View the surface as contours or triangles, or create elevation and slope banding analysis.
Terrain-shaping tools support large-surface 3D models while maintaining dynamic relationships to source data including contours, breaklines, corridor models, and grading objects. Use surfaces as references to create profiles, sections, and corridors. Changes to the source data result in automatic updates, helping you to save time and minimize errors.
With AutoCAD Civil 3D, use powerful daylighting and grade-projection tools to generate surface models for several types of grading projections. Develop surfaces with easy-to-use graphical and tabular grading manipulation tools. Help solve design problems using grading capabilities that remain dynamically linked to corridor models and alignments or profiles.
The software enables you to more quickly process earth volumes between your existing and proposed surfaces using composite volume or average end area methods. Generate mass haul diagrams for analyzing the distance over which cut and fill can balance, the amount of material to be moved, the direction of movement, and the identification of borrow pits and dump sites.
Alignments & Profiles
Create alignments and profiles based on agency standards using more flexible geometry layout tools that enable you to check standards as you design. Control alignment constraints, including alignments imported from LandXML, and gain flexibility when creating alignments.
Corridor modeling combines horizontal and vertical geometry with customizable cross sectional components to create a parametrically defined, dynamic 3D model of roads and other transportation systems. Use the included subassemblies—ranging from travel lanes, sidewalks, and ditches to complex lane components—or create your own based on a design standard. The model can be easily modified via visual interaction or by changing input parameters that define the roadway typical section. Unique characteristics of each subassembly allow the 3D model to target known features.
Use rules-based tools to lay out sanitary and storm drainage systems. Break or join existing pipe networks or make changes to pipe networks and structures using graphical or numerical input and conduct interference checks. Plot and complete final drafting of the pipe network in plan, profile, and section views, and share pipe network information, such as material and size, with external analysis applications.
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.
Data Shortcuts and References
With data shortcuts and xrefs, project members can share model data such as surfaces, alignments, and pipes, working off the same instance of a design object for multiple design tasks. Annotation can also be generated from the data shortcuts or directly through an xref to help production drafting remain in sync.
Create point clouds in AutoCAD Civil 3D using data from LIDAR. Import and visualize point cloud information; stylize point data based on LAS classifications, RGB, elevation, and intensity; and use data to create surfaces, perform site surveys, and digitize as-built features for civil engineering design projects.
Create more powerful visualizations that give stakeholders an opportunity to better envisage the project before it is built. Produce visualizations directly from the model for several design alternatives to help better understand the impact of the design on the community and the surrounding environment. Publish the model to Google Earth™ mapping service for even greater understanding of the project in context. Make near photorealistic renderings of your models using Autodesk® 3ds Max® Design software. Simulations using the Civil 3D model can be created in Autodesk® Navisworks® software, which can help project stakeholders better understand how the project will look and perform once built.
