Highlights

Surfaces, Grading, and Dynamic Relationships
AutoCAD Civil includes terrain shaping tools that support large surface models while maintaining dynamic relationships to source data, including contours, breaklines, corridor models, and grading objects. Use surfaces as references for creating profiles, sections, and corridors. Any change to the source data results in automatic updates to surfaces and references, helping you save time and reduce errors.

The powerful daylighting and grade projection tools included in AutoCAD Civil can be used to generate surface models for any type of grading projection. Easy-to-use graphical and tabular grading manipulation tools help you develop any surface. Solve challenging design problems using grading capabilities that remain dynamically linked to corridor models and alignments/profiles.

Parcel Layout with Intelligent Topology
Generate parcels by converting existing AutoCAD® polylines or by using flexible layout tools to automate the process. Use the intelligent topology to manage parcels so that a change to one parcel is automatically reflected in neighboring parcels.

Intelligent Pipes Layout
Use rules-based tools to lay out sanitary and storm drainage systems. Make changes to pipes 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 invert elevations, size, slope, and type with external analysis applications or AutoCAD® Civil 3D® software.

Criteria-Based Geometric Design
Quickly lay out dynamic plan and profile alignment geometry with local design criteria that you specify. These constraints remain in place when using interactive “best fit,” PI-based (point of intersection), or highly flexible element-based layout approaches.

Intelligent Corridor Modeling
Create intelligent models of roads and other transportation systems using the corridor modeling functionality in AutoCAD Civil. Corridor modeling combines horizontal and vertical geometric constraints with customizable cross-sectional components called subassemblies to create a dynamic model of various types of transportation systems. Use the subassemblies included with AutoCAD Civil—ranging from travel lanes, sidewalks, and ditches to complex lane components—or create your own to match local design standards. Directly use alignments, profiles, survey figures, feature lines, and AutoCAD polylines to define corridor transitions and elevation constraints.

AutoCAD Civil also provides an interactive intersection builder that helps to create complex models through intersecting streets that remain dynamic as your designs change. Corridor models can ultimately be used to create proposed surfaces, earthwork volumes, material totals, drafted cross sections, and more.

Facilitate Team Coordination—Synchronizing Design Changes
Your entire team can work from the same consistent, up-to-date model. Team members can stay better coordinated through all phases of the project, from survey to construction documentation. Using AutoCAD external references, data shortcuts, and Autodesk® Vault software, project team members can share individual model elements, such as surfaces, alignments, and pipes, while working off the same instance of a design object for multiple design tasks. Design changes are synchronized using one model that can result in multiple updates across several drawings—and they are automatic.

Dynamic Earthwork Calculations and Mass Haul Diagrams
The fully integrated mass haul and earthwork features in AutoCAD Civil aid contractors and engineers in planning the movements, amounts, and placements of material during construction. As designs are changed, AutoCAD Civil can quickly generate mass haul diagrams to help analyze the distance over which cut and fill will balance, both in the amount of material and the direction of material movement to assist in identifying borrow pit and dump sites.

Styles, CAD Standards, and Production Drafting
CAD and design standards are an important component of a project. Use the extensive library of country-specific CAD styles included with AutoCAD Civil to help control virtually every aspect of drawing display. Colors, linetypes, contour increments, and labeling are controlled by styles. AutoCAD Civil provides a framework for customizing your own styles and standards to meet the specific needs of your organization. Automatically generate construction documents using the styles-based drafting environment to automate the creation of drafting while maintaining drafting standards. Use xrefs and data shortcuts to generate drafting across multiple drawings. When the model changes, the construction documentation is automatically synchronized to reflect the update.
