Survey functionality is fully integrated in Civil 3D, so you have a more consistent environment for all tasks, including direct import of raw survey data, least-squares adjustment, editing of survey observations, and automated creation of survey figures and surfaces. You can create and edit survey figure vertices interactively, and identify and edit crossing break-lines to avoid potential issues, resulting in points, survey figures, and surfaces that can be used throughout the project.
Surfaces and Grading
With Civil 3D, you can build surfaces from traditional survey data, such as points and break-lines. 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. Use surfaces as a reference for creating intelligent objects that maintain dynamic relationships to the source data. Team members can use the powerful daylighting and grade projection tools to generate surface models for any type of grading projection.
Corridor modelling 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.
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 analysing 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.
Purpose-Built Tools for Road and Highway Design
Transportation-specific design tools offer a more efficient way to design roads and highways. Build interactive intersection models that dynamically update. Focus on optimizing the design and know the production drawings and annotations stay up to date. Lay out roundabouts more quickly, including signage and striping, based on common design standards.
