Key Features

Smarter Subdivision Road Design, Powered By AI

AI for subdivision design reduces the time taken to layout a subdivision road network from hours or days to just minutes. This feature deduces your design intent based on how you name your alignments and learns as you make corrections.

Intuitive 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, widenings and cul-de-sacs. 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 and cul-de-sacs. 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.

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.

Real Time Interactive Visualization

The Corridor EZ ‘Model Viewer’ assists your design process 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.

Multi Baseline 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.

Learn, Support, Problem Solving

Whether you need expert technical support, custom training for your team or prefer self-directed eLearning – we’ve got it all.
