If you’ve ever built a complex Civil 3D corridor from scratch, you know the time it takes to set up multiple regions, target mapping, and assemblies—not to mention keeping everything organized.
With Corridor EZ for Civil 3D V26, that process now takes minutes instead of hours or days. In V26, we’ve streamlined the Corridor Exchange process so you can create a complete, fully targeted Civil 3D corridor—just the way you would—at the click of a button.

Two key upgrades make this possible:
1. Faster Corridor Creation
When we generate your corridor, Corridor EZ automatically builds the required assemblies, applies all target mapping, and sets parameter overrides to match your design intent.
In V26, this process is 50% faster, so you can push your design into the build process and start refining it in Civil 3D almost immediately.
2. Smarter Assembly Consolidation
We’ve reworked how assemblies are generated so they closely match what an experienced Civil 3D user would create—reusing and consolidating wherever possible.
For example, a straightforward corridor with multiple roads, curb returns, cul-de-sacs, and knuckles will now produce just 7–13 assemblies instead of the 100+ assemblies you’d see in earlier versions.
That means cleaner projects, easier navigation, and less clutter when working through your baselines and regions.
With V26, Corridor EZ doesn’t just save time—it delivers corridors that feel hand-built, but without the manual grind.
