With Corridor EZ, you can spend hours on your entire design and production process rather than weeks.
A simple plug-in for AutoCAD Civil 3D to speed up corridor creation.
Designing and modeling Corridors, Intersections, and Cul-De-Sacs in Civil 3D is always a difficult, time consuming, and error-prone process. Intersections, in particular, are the bane of any designer’s existence. Developing countless Assemblies, targeting them, setting the sub-assembly properties, then tying them into specifically named categories for regions of an intersection can take days of work.
What if there was a better way? A way to design complete roadway designs with one click of a button?
Welcome to Corridor EZ, the simplest, most powerful, and fastest roadway and intersection design tool you’ve ever seen – and it runs right inside the AutoCAD Civil 3D system you’re already using! Using Artificial Intelligence, Corridor EZ can build your corridor model, intersection, cul-de-sacs, even widenings and turn out lanes automatically from any collection of AutoCAD Civil 3D Alignments. Not only that, but Corridor EZ will also generate your surface TIN at the same time.
ZenTek Consultants is the Premier Partner for Corridor EZ, Stringer Topo and Civil Site Design in the U.S. and Canada, and we’d love the opportunity to show you how these amazing systems can dramatically improve your projects at a far lower cost than you’d imagine.

Corridor EZ for Civil 3D increases your productivity by automating the most complex part of Civil 3D – corridor creation.
Corridor EZ doesn’t just build initial roadway and intersection designs quickly, it also gives you easy to use editing and design control features that you just don’t have in standalone Civil 3D. Intuitive Vertical Grade editing, fast modification of cross sections, targeting of any polyline, alignment, or surface and much more! The Corridor EZ Template Editor lets you build even the most complex road section in minutes, with multiple sub-grades of any thickness or material and save them to job based or public libraries for use on other jobs. Corridor EZ even gives you real time volume calculations for your roads as either full cut/fill by station or materials.
Best of all, even if you need to output to a Civil 3D standard corridor to share with partners or because of deliverable requirements, Corridor EZ has you covered. With just one button click, the Corridor EZ road model can be converted to a complete Civil 3D Corridor, with assemblies, styles, etc., set to your specifications. Not only that, but you can continue to edit the roads using Corridor EZ’s improved toolset and have it sync to update the traditional Civil 3D Corridor.
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. Easily modify profiles, sections, and surfaces built from your corridors, with simple tools you access via right-click. No more hunting through menus or ribbons to get to the command or object you want!
Corridor EZ provides a spreadsheet-like template manager to define your road, curb, sidewalks, pond elements and related grading polylines. Easily customize the templates to meet specific project needs and take the guess work out of building complex assemblies. When your design is complete and you are ready to create a corridor – Corridor EZ will create the required assemblies for you.
Using Project Assist, Corridor EZ delivers intelligent, AI-driven creation of your entire road network. 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.
In a single mouse click, you can push your designs out to AutoCAD Civil 3D Profiles, complete with Profile Views. Edit your Civil 3D profiles and read back to the design to update all your curb returns, cul-de-sacs and knuckles.
You can also 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. No need to use split views and hunt for profile views.
Once you complete your design, simply export it to AutoCAD Civil 3D Surfaces at the click of a button - and it includes 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 styles.
Use the Corridor EZ Model Viewer during the design process to assist with real-time rendering and visualization. It has a number of powerful analysis tools including line of sight analysis and reporting, automated line marking which can be exported to your CAD drawing.
