Project Assist uses AI to Understand Your Road Network Design Intent
Civil Site Design – an add-on to Civil 3D since 2007 – has revolutionized the design process with design automation. Project Assist takes this automation to the next level with AI.
Using an existing ground surface and alignments for road centerlines, turning lanes, bus bays, bull nose curbs and islands Project Assist will:
- Understand your design intent and provide you with a form for review and editing
- Build out your design assigning road templates with a best fit vertical design
- Add curb returns tied directly to the connecting roads
- Automatically design your more complex segments including turning lanes, widenings, cul-de-sacs, knuckles and islands.
Ask your senior designers how many hours it would take to generate an initial design for the road network shown in this subdivision.

Understanding Project Assist’s Workflow
You begin with an existing ground surface and then the designer:
- Create and name alignments for the road centerlines
- Create and name alignments for widenings, turning lanes and bus bays
- Create and name alignments for knuckles, parking stalls and islands
- Identify the location of all cul-de-sacs
Activate Project Assist and it’s AI engine will read all alignments and provide you with a form displaying the what it believes you want to do with each based on the alignment type you select.
When you confirm the alignment usage, another form is generated defining the actual workflow Project Assist proposes.
You can review each proposed action and make adjustments as required. As you make these changes, the AI will continuously learn your alignment naming convention.
Project Assist Detailed Design Workflow
It is in this form that you can fine tune your design intent:
- If you have a custom alignment for a cul-de-sac – you can define it here with the “is cul-de-sac” option.
- If you are defining the curb return for a parking lot you would create a separate string that allows users to independently edit the vertical and horizontal design and assign a curb return template.
Many subdivisions have standard cul-de-sac definitions which can be defined in the Project Assist settings. Cul-de-sacs can be added to a road by checking the Add cul-de-sac box. These can be updated or modified later using the cul-de-sac edit option within the core software.
Finally, you are able to define a default curb return radius that will be used throughout your project. Curb returns can be easily modified during the detailed design phase.
PDF Summary Report
Once confirmed – Project Assist will automatically build out your design and then generate a PDF file describing each step taken in the design along with links to videos that show exactly the actions taken – a great training tool for new users. and a quality assurance report for senior designers.
Project Assist Results – A Complete Preliminary Design in 5 Minutes
Below is the preliminary design that Project Assist generated for this subdivision in under 5 minutes.
Civil Site Design generates the vertical design of the entire road network with all curb returns dynamically updated as design changes are made.
It also provides an intuitive user interface allowing you to:
- View and edit the design profiles
- Examine and edit Cross Sections directly
- Generate your profiles directly when needed
Civil Site Design’s Project Assist revolutionizes the subdivision design process by:
- Analyzing your alignments
- Understanding your design intent based on the naming convention used and learning as you make adjustments
- Adding automation to the more complex processes such as widenings, bus bays, parking lots, knuckles and islands
- Allowing new designers to become productive quickly and easily share designs with senior designers
- In Civil 3D and Corridor EZ your existing production standards are maintained and your profiles, design surfaces, feature lines and corridors are automatically created
- With Civil Site Design for BricsCAD and AutoCAD, plan/profile sheets and cross-sections are created automatically
