Design and deliver better civil infrastructure with BIM
Autodesk Civil 3D® civil engineering design software supports BIM (Building Information Modeling) with integrated features to improve drafting, design, and construction documentation.
Industry-proven tools for your specific project
Civil 3D features support a variety of civil infrastructure projects including rail, roads and highways, land development, airports, drainage, storm and sanitary, and civil structures.
Advance your workflows with GIS integration and automation
Work with ArcGIS data directly in your Civil 3D design model. Expedite completion of repetitive tasks with design automation.
Features
Relative elevation feature lines
Obtain feature lines from a surface or relative to a surface, so feature lines update with changes to the surface.
Dynamic offset profiles
Create dynamic offset profiles using a default cross slope. Modify them by editing the profile properties.
Connected alignments
Create a new dynamically linked alignment and profile that transitions between 2 intersecting alignments and their profiles.
Pipe sizing and analysis
Resize pipes and reset inverts, and compute the energy and hydraulic grade lines according to HEC-22 2009 standards.
Plan and profile sheet generation
Create plan/plan and profile/profile sheets by including multiple plan or profile views on a single sheet.
Label property set data
Add custom data to Civil 3D object labels by using property sets.
Traverse editor
Create points, lines, and curves representing traverse legs and sideshots using COGO input and editing tools.
Corridor overlap resolution (bowties)
Resolve corridor bowties in daylighting conditions.
ENHANCED | InfraWorks interoperability
Use preliminary design models within Civil 3D.
ENHANCED | Pressure pipe networks
Swap pressure network pipes, fittings, and appurtenances with parts of another size or type.
