Fast & Dynamic Corridor Alignment Creation & Editing

Design road and corridor alignments with a clean, focused interface. Every view updates instantly as you edit — so you always see the full impact of your design decisions in real time.

Site Design

A variety of simple, but powerful features are available for site design and grading. Create virtually anything in 3D — from bridge sites to drainage networks — all within your existing project environment.

Terrain Modelling & Survey Data Management

Create digital terrain models (TIN) from almost any topo data, including large point sets like UAV or LiDAR data with over 10,000,000 points. Build contours, labels, and customize your display with slope vectors and colour shading for slope, aspect, and elevation.

Explore Corridor Options in Minutes with Path Explorer AI

Path Explorer AI is a quick & easy, preliminary road locating tool inside of the Terrain module. It is built to find optimized routes between two points, A & B, and does so in minutes!

You can include constraints like max grade,  min cut / max fill, no-go zones, high-cost zones, and crossing costs.

Cross-Section & Template Control

Location Module -  A flexible template editor allows you to assemble typical sections using a library of customizable components. Account for ditches, pavement, sub-base materials, varying lane widths, cut slopes, variable height fill slopes, curbs, sidewalks etc.

Visualize the template in typical sections (or at a specific station) prior to implementing in your design.

Earthwork Volumes & Costs As You Design

Location Module - Get your earthwork and material volumes, as well as the sub-grade construction costs. 

With earthwork costing data as you design, you can adjust your design based on cost. Compare costs for design alternatives. Know preliminary construction costs before you build.

Watershed & Hydrology Tools

Effective drainage management is essential on any project site. Terrain module’s hydrology tools help model surface water flow with key functions: generating watershed areas, calculating drainage to specific points or features, identifying streams and ponded areas, and tracing flow paths. These tools support better drainage design and water management decisions.

Culvert Design

Location Module - RoadEng includes two primary methods for the design of culverts, cross drains and fish passages. Add simple culverts using the culvert editor panel. Culverts can also be designed in more detail using multiple alignment functionality.

Simple Intersections & Driveways

Location Module - Model more complex geometric situations, including simple intersections and driveways, using basic surface modelling tools such as multiple alignments, reference features and corridor surfaces

Easily Include Web-Imagery

Terrain Module - Live Maps tool provides direct online access to free imagery and low-resolution DEM data. Automatically georeferenced and brought into the background of it into your project.

GPS-Enabled Field Solutions

All Modules - Designed to work on all Windows 10-enabled tablets and compatible with most internal/external GPS devices. GPS integration in all modules allows you to view where you are in Plan, Profile, or Section view at any time. Create GPS tracks on your primary survey data. Create georeferenced PDFs for use with Avenza Maps.

Output & Sharing

Location Module - Easily share and showcase your design with Multi-Plot Report Builder. Print out plan, profile, and cross-section data as one document. Simplify your presentation of deliverables with single document control. Output sheets interactively update with your design. 

Easily output and share with other programs. RoadEng and Softree Optimal both work alone, or it can integrate into other CAD or GIS-based engineering systems. Easy export to machine control through LandXML.
