Updated Pressure Networks

New tools deliver more precise layout control, improved fittings, and better analysis integration for utility design.

Automation with Dynamo

Dynamo for Civil 3D has been updated with additional libraries, enabling engineers to automate repetitive tasks through visual scripting.

Better Collaboration

Civil 3D integrates more efficiently with Autodesk Docs, offering faster file syncing, revision tracking, and improved multi-user collaboration.

Core Features

Dynamic Model Updates

Civil 3D uses a connected modeling system where changes made in one part of the project automatically update across the entire model. This supports accuracy and prevents inconsistencies.

Alignments & Profiles

Essential tools for roadway design, rail design, and site infrastructure. Alignments and profiles can be edited dynamically with engineering-level precision.

Grading Tools

Civil 3D offers customizable grading objects, feature lines, and grading groups for creating pads, slopes, and site layouts.

Corridors

Corridor modeling is one of the most powerful features of Civil 3D. Corridors combine alignments, profiles, and assemblies to support roads, highways, runways, and complex transportation designs.

Pipe Networks

Design stormwater, sanitary, and pressure systems with intelligent rules-based tools, automatic labeling, and profile integration.

Terrain & Surface Modeling

Civil 3D includes advanced terrain modeling tools:

• TIN surfaces

• Breaklines

• Contour editing

• Point cloud processing

• Survey data import

Civil engineers can create accurate digital terrain models for grading, visualization, and design calculations.

Corridor & Roadway Design

Civil 3D offers sophisticated roadway design capabilities:

• Multiple baseline corridors

• Conditional subassemblies

• Intersection modeling

• Roundabout design

• Lane and shoulder controls

These tools allow engineers to design safe, efficient, and compliant transportation systems.

Pipe Networks & Utilities

Civil 3D supports pipelines and underground networks:

• Gravity pipe networks

• Pressure systems

• Utility modeling

• Automated labeling

• Plan and profile views

Users can simulate, design, edit, and document pipeline networks with accuracy.
