Civil Design Productivity Tools for Civil 3D and BricsCAD
ChasmTech delivers high-productivity civil engineering workflows for firms using Civil 3D and BricsCAD. Our specialized solutions—including Civil Site Design and Corridor EZ, —help engineering and surveying teams accelerate subdivision design, roadway reconstruction, grading, and survey production.
By automating repetitive tasks, simplifying corridor management, and reducing manual rework, ChasmTech enables firms to complete projects faster, improve design efficiency, and increase production capacity without increasing headcount.
Boost Your Design Efficiency with Proven Workflows
Civil Site Design – Subdivision, Road and Site Design Made Easy
Civil Site Design is an advanced civil engineering workflow platform for Civil 3D and BricsCAD. It helps engineering firms accelerate subdivision design, roadway reconstruction, grading, and survey production.
Intelligent automation tools convert point clouds and survey data into optimized surfaces, generate alignments from polylines, and work directly with Civil 3D surfaces and alignments to streamline project workflows.
Designed to reduce repetitive production tasks, Civil Site Design automates the creation of roads, linked curb returns, cul-de-sacs, knuckles, corridors, and intersections while dynamically updating annotated plan/profile sheets and cross-sections as designs evolve.
Integrated pipe network tools further simplify storm and utility design by allowing engineers to create, manage, and display pipe networks directly within profile workflows.
The result is faster project delivery, improved design iteration, reduced manual rework, and increased production capacity for modern civil engineering teams.

Corridor EZ – Smarter, Faster Subdivision Design and Corridor Creation for Civil 3D
Civil 3D users know that corridor design can be a slow, repetitive process. Corridor EZ is a purpose-built add-on that helps you speed up roadway and subdivision modeling by up to 80%, eliminating tedious setup steps and reducing design errors.
This proven Civil 3D productivity tool simplifies complex intersection, cul-de-sac, knuckle and roundabout creation while keeping you fully in control of your design standards.
If you’re looking for fast road network design and simplified corridor generation that works directly inside Civil 3D, Corridor EZ is the solution that saves time, increases accuracy, and helps you deliver more projects with fewer resources.
