Corridor EZ for Civil 3D increases your productivity by automating the most complex part of Civil 3D – corridor modeling.

Corridor EZ fast tracks your design, starting with your alignments and surfaces, to create Civil 3D surfaces, profiles, profile views, assemblies and corridors.
Spend minutes, not hours, on your entire design and production process.
Corridor EZ seamlessly integrates with

Key Features of Corridor EZ for Civil 3D
The short videos below will show you how Corridor EZ for Civil 3D greatly simplifies and speeds up corridor design.

Intuitive Corridor EZ Toolspace
The Corridor EZ Toolspace is intuitive and simple to use, providing a one-stop-shop for you to create, edit and manage all your design objects.
Select any object, or object collection, and right click to obtain a contextual menu of commands available for that object. No more hunting through menus or ribbons to get to the command or object you want!
Templates Simplify Assemblies
Corridor EZ provides a spreadsheet-like template manager to define your road, curb, sidewalks, pond elements and related grading polylines.
Templates replace the need to build complex assemblies and can be easily customized to meet specific project needs.
When your design is complete and you are ready to create a corridor – Corridor EZ will create the required assemblies for you.


Intelligent Road Network Design
Corridor EZ delivers intelligent, AI driven creation of your entire road network via ‘Project Assist’.
Once your surface and alignments are created, you can assign your templates and ‘Project Assist’ generates the design for an entire subdivision in a single operation including all curb returns, cul-de-sacs and knuckles.
All these elements are tied together so changing the vertical design of one road updates all of the connected profiles
Leverage the Civil 3D Profile
Push your designs out to Civil 3D Profiles, complete with Profile Views, with a single mouse click. Edit your Civil 3D profiles and read back to the design to update all your curb returns, cul-de-sacs and knuckles.
As well, you can open multiple interactive design windows to edit your profile designs and view your cross sections, complete with plan tracking and dynamic updating as you change your design. There is no need to contend with split views and the hunt for profile views.


Corridor EZ Surface Output
Once your design is complete, you can export your design to Civil 3D Surfaces at the click of a button, including all breaklines and boundaries.
If you make a change in your design, re-run the export to update all the surface definitions, maintaining all your surface labels surface analysis and applied surface style.


The First Civil Design Software to Introduce AI for Subdivision Design
The Benefits of AI in Subdivision Design
- Design speed is everything in today’s competitive environment.
- Corridor EZ‘s AI for subdivision design reduces the time taken to layout a subdivision road network from hours or days to just minutes.
- The software deduces your design intent based on how you name your alignments and learns as you make corrections.
The Corridor EZ Challenge
A Civil 3D pro builds out a preliminary subdivision design and generates the corridor and Civil 3D profiles in 30 minutes compared to 8 hours using Civil 3D alone using the Corridor EZ Project Assist AI.
Why Your Business MUST Consider Corridor EZ for Civil 3D
Angel Espinoza, an Autodesk Civil 3D technical guru, had this to say about Corridor EZ:
“But, for 4 minutes’ worth of work, to do 33 intersections along 26 streets this is ama-za-zing stuff. “
