Corridor EZ for Civil 3D

The Essential Add On For Autodesk Civil 3D®

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

Corridor EZ fast tracks your design, starting with your alignments and surfaces, to create Civil 3D surfaces, profiles, profile views, assemblies and corridors.

Spend hours on your entire design and production process rather than weeks.

Watch this real-life video of Ryan Caudell - use the power of Corridor EZ to design the road network, widenings, turning lanes, curb returns and generate a corridor in 5 minutes.

Key Features of Corridor EZ for Civil 3D

Keep what you love about Civil 3D – upgrade the rest!  Some of the key features of Corridor EZ are described below.


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.

Automatic assembly creation

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

Automatically Create Civil 3D Profiles With Your Styles

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.

And Finally - The Corridor

At the click of a mouse, create a multi base line Corridor – including all assemblies, targets, regions and overrides.

Need to make a change – another road or knuckle? No problems – simply sync your Corridor.


Corridor EZ will automate your initial road network design and generate a corridor in minutes!
