OpenRoads Designer User Guide

A Practical Guide to Road Design, Terrain Modeling, Corridors, Drainage & Construction Documentation

Modern roadway design requires more than drawing lines and producing plans. It involves coordinating terrain, geometry, corridor models, drainage, utilities, quantities, cross-sections, and construction documentation into one organized workflow.

OpenRoads Designer User Guide provides a practical introduction to this process, helping readers understand how the major components of a civil infrastructure project fit together.

Starting with project setup and basic working concepts, this guide progresses through the complete roadway design workflow. You will learn how to work with survey information, develop existing terrain models, create horizontal and vertical geometry, build roadway templates, generate 3D corridors, apply superelevation, and coordinate complex roadway features.

The guide also explains important supporting workflows, including drainage, utilities, intersections, earthwork, quantities, cross-sections, plan production, profiles, sheets, and final project delivery.

• Project Setup & Organization - Understand files, models, references, units, standards, and project structure.

• Survey & Terrain Modeling - Import survey information, work with terrain data, inspect surfaces, and manage breaklines.

• Horizontal & Vertical Geometry - Develop alignments, curves, profiles, grades, and vertical curves.

• Templates & Corridor Modeling - Build roadway cross-sections and develop coordinated 3D corridor models.

• Superelevation - Understand cross-slope transitions and their relationship to roadway geometry and corridors.

• Intersections & Roundabouts - Coordinate roadway connections, turning areas, curb returns, and complex transitions.

• Drainage & Utilities - Organize drainage networks, structures, culverts, and underground utility coordination.

• Earthwork & Quantities - Analyze cut and fill, review cross-sections, and understand material quantities.

• Plans, Profiles & Sheets - Transform model information into organized construction documentation.

• BIM & Project Delivery - Understand model-based coordination, references, quality control, and final deliverables.

Beyond the main chapters, the book includes useful appendices containing:

• Essential tools and workflow references

• Common civil engineering terminology

• A roadway design checklist

• Troubleshooting solutions for common modeling problems

• A complete example workflow from survey data through final construction documentation

The emphasis throughout the book is on understanding the design process rather than simply memorizing commands. By following the workflow from existing conditions through final documentation, readers can develop a clearer understanding of how changes to one part of a project can affect the rest of the model.

Whether you are a student, beginner, civil engineering professional, roadway designer, technician, or simply looking for a practical reference to support your learning, this guide provides a structured foundation for working with OpenRoads Designer.

Build your knowledge from the ground up-from survey and terrain to geometry, corridors, infrastructure, quantities, and final plans.

Learn the workflow. Model with confidence. Review your design. Deliver professional results.
