Civil 3D 2025 – Single-User Subscription – Government Autodesk

More features

Surface Modeling

• Surface modeling tools – Create surfaces composed of a combination of points, breaklines, boundaries, and contours with support for TIN, Grid, and Cropped, and Corridor surfaces.
• Point cloud tools – Use a large collection of points acquired by laser scanners and other capture technologies to create digital representations of existing conditions and structures. Import the point data to Civil 3D to generate a 3D model to be used in your design project.
• Surface editing – Work with editing tools that add edits to a surface definition as edit operations and not to any of the existing surface data components.
• Surface masks – A display tool that enables you to block out areas of a surface and prevent them from being displayed or to render a section of the surface using a specified render material.
• Surface watersheds – Analyze how water flows along and off a surface to better determine drain targets and watersheds.
• Surface volumes – Use the Volumes Dashboard to calculate and analyze volume surfaces and bounded areas within those surfaces.
• Surface analysis – Conduct surface-related analysis, including contour, directions, elevations, slopes, slope-arrows, watersheds, and water drop path.

Site and survey

• Site design tools – Manage objects (parcels, alignments, gradings, and feature lines) with a common topology in a site collection.
• Survey tools – Streamline the download, creation, analysis, and adjustments of field-captured survey data.
• Field-to-finish workflow – More efficiently process field-captured survey data to create an intelligent base map in Civil 3D.
• Geotechnical modeling – Visualize and analyze geotechnical data then use that data directly in the Civil 3D design model.
• Grading tools – Grading tools and commands facilitate the efficient design of finished ground surfaces.
• Grading Optimization (AEC Collection only) – Automate the process for conducting grading design studies for land areas based on established design project criteria.

Corridor modeling

• Corridor design tools – Create dynamic and data-rich corridor models for highways and roads. Build rail track corridor models, incorporating designs for switches, turnouts, and cant calculations.
• Export corridor data – Extract corridor feature lines with ease to use as a basis for creating grading objects or other design projects. Extracting feature lines can be done all at once, selected one-by-one, or by selecting a subset within a corridor region or a polygon.
• Assemblies and subassemblies – Efficiently use assemblies and subassemblies to establish the basic building blocks of a roadway or other alignment-based design.
• Intersections and roundabouts – Create dynamic 3-way, 4-way, or roundabout intersections.
• Advanced roundabout design – Model roundabouts according to defined standards. Build your roundabouts into existing corridor models, enabling your design to update automatically when you make changes to the corridor alignments.

Storm and sanitary

• Modeling pipe networks – Efficiently draw 2D and 3D models of utility systems, such as storm sewers, sanitary sewers, and more.
• Hydraulics and hydrology tools – Perform a variety of stormwater management tasks, including storm sewer design, watershed analysis, detention pond modeling, and culvert, channel, and inlet analysis.
• Pressure network design – Generate 3D models of pressure networks, such as water transmission systems.

Plan production and documentation

• Plan production and construction documentation – Create plan-only, plan and profile, profile-only, and section sheets by including multiple plan or profile views on a single sheet.
• QTO and earthwork calculations – Extract and report material volumes and analyze quantities from materials and sectional or profile information.

Productivity and automation

• Dynamo for Civil 3D – Use the Dynamo visual scripting environment to develop routines that automate repetitive design tasks and expedite workflows.
• Project Explorer for Civil 3D (AEC Collection only) – Manage the staggering volume of design data in Civil 3D models in this all-in-one hub. Easily review, validate, report, export and edit models. Gain a better understanding of your design and more efficiently control the distribution of geometric information to project stakeholders.

Interoperability

• Corridor data shortcut (DREF) – Create and share data shortcuts for corridors.
• 3ds Max interoperability – Create professional-quality visualizations.
• IFC import and export – Import and export AutoCAD solids to IFC files.
• Exchange data with InfraWorks – Bring context modeling and conceptual design into your design process. Make better decisions with a real-world context of existing conditions, more efficiently consider alternatives, and complete detailed design and documentation in Civil 3D.
