Road Design an Easier Way

RoadEng is an interactive civil engineering design software for road, rail, and other linear projects.

Why RoadEng?

  • It is fast, light, & easy to use.
  • Specialized for road & corridor engineering. 
  • RoadEng handles larger data sets in ways other civil design software cannot, and longer projects without needing a supercomputer,
  • It has patented advanced earthwork optimization* and cost reduction tools. 
  • It has an AI tool for preliminary design*.
  • No additional CAD software is required.

* Softree Optimal add-on required

RoadEng Features & Functions

Fast & Dynamic Corridor Alignment Creation & Editing 

Location Module - Geometric corridor design in a simple and intuitive user interface. Visualize your road design in 3D, plan, profile and section views simultaneously. Make a change to the project, dynamically watch all of the windows update.

Site Design

Terrain Module - A variety of simple, but powerful features are available for site design and grading. Create virtually anything in 3D: bridge sites, terracing, pipes, surfaces, channels, ditches, pads or sub-surface zones.

Terrain Modelling & Survey Data Management

Terrain Module - 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. Create contours, labels, and customize your display with slope vectors, and color 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.   (*Part of Softree Optimal add & annual support exclusive feature.)

Path Explorer AI

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

Terrain Module - Easily determine catchment areas of the TIN model and create corresponding features. The automatic calculation of watershed areas is based on a regular grid. The user can choose the grid cell size. An additional drainage area feature allows users to determine the drainage area associated with a specific point, useful in culvert design projects (new Version 10 feature).

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.

In Mahnomen County, our problem has been finding a road design software package that is simple enough for our technicians to learn and retain after a season of being in the field, but that is also powerful enough to do the things that we need to accomplish in our road designs.

Our Engineering Technicians find it easy to learn and use, and the quantities generated by the program have been very accurate. The other thing I have been very pleased with is the technical support for the program. The group at Softree has been very quick to answer any of our questions and have been great to work with. "
