Civil Site Design for AutoCAD Civil 3D

The only Civil 3D companion that significantly increases Civil 3D's productivity

For more than a decade now, AutoCAD Civil 3D has been the king of the civil/site/survey world. It’s an immensely powerful tool that handles even the most complex designs and gives you highly customizable tools for just about any civil-related scenario you can imagine. The problem is that very often it’s just too complicated to work in effectively. Even those who work in Civil 3D every day still avoid many of its features because they’re just too difficult and time-consuming for use on many small/mid-size projects.

Many firms regularly avoid building Civil 3D Corridors, Pipe Networks, and even Gradings because they’re just too difficult and require far too much time to become comfortable with. What the civil world really needs is a tool that will let you easily generate and modify all the 3D site modeling tools you need, without the extended learning curve. A tool that will integrate with Civil 3D but simplify your daily workload.

Let us introduce you to Civil Site Design, a cost-effective, and immensely powerful civil/site/survey solution for Civil 3D that gives you all the design tools of Civil 3D but in a much faster, easier-to-use format. Not only will Civil Site Design give you all the 3D modeling tools you need, its output can be converted directly to Civil 3D objects for collaboration with other firms/groups using that system. Better yet, Civil Site Design’s tools and user interface have been designed to be immensely flexible while maintaining ease of use. Civil Site Design uses common 2D interfaces and drafting concepts to develop their modeling, not complex and convoluted command structures you need to learn from scratch. Civil Site Design tools are meant to be very intuitive for anyone who has a site design background, keeping you focused on the actual design and not on complicated software procedures. Civil Site design plugs directly into your current Civil 3D package, providing you with the tools you need, right inside the system you're using today!

Key Benefits of Civil Site Design for Civil 3D

  • Design Automation Improves Civil 3D
    Civil Site Design has dozens of design automation and visualization tools that will save 100's of hours of design effort on virtually every project.
  • Civil 3D Will Crash Less Frequently
    Civil Site Design writes design information to an external folder. This reduces the size of the drawing and should you experience a crash, Civil Site Design automatically recovers all of its design information and labels.
  • Civil 3D Will Load Faster
    During the early stage of your design your drawings will not become bloated with Civil 3D objects, Civil 3D will load significantly faster.
  • Easily Generate all Civil 3D Objects
    Most importantly, when you have finished your detailed design work, Civil Site Design will generate your Civil 3D surfaces, profiles, corridors, assemblies and surfaces automatically. Users can edit a profile in Civil 3D and then post them back to Civil Site Design.
  • Use Your Existing Styles
    Your existing styles are automatically applied to the new Civil 3D objects. Designers and drafters continue to use your standard tools for documentation. No additional training. No interruption to your procedures.

Civil Site Design Features

Project Assist

Artificial intelligence and machine learning are now considered to be one of the biggest innovations since the microchip. As this technology continues to improve and evolve, the more we use it in our daily life.

The Development Team at Civil Survey Solutions have been following the evolution of A.I. and leveraging machine learning technology to build tools to assist civil designers.

Project Assist is designed to allow even junior designers to become productive quickly. Using named alignments, it learns your design intent and generates a design document for the project. Senior designers can review the design document, make changes and share the design drawing amongst the design team.

Surfaces From Point Files, Point Clouds and Satellite Data

In addition to your normal Civil 3D surface functions, Civil Site Design incorporates the ability to read point clouds directly with intelligent filtering. You can use the ground surface for design and to visualize your design in Model Viewer with the point cloud overlay.​

The satellite to surface feature will geo-reference your drawing and will use Google elevation data as well as imagery from multiple sources to generate a surface and overlay the image. This is a perfect option for preliminary design and for watershed analysis with HEC RAS.

Civil 3D Corridor Creation

Managing and editing corridors and assemblies is one of the most complex and least understood process in Civil 3D.​

A key feature of Civil Site Design is the automatic creation of your design surfaces, profiles, assemblies and corridors from the Civil Site Design model. Once created, users can edit their profiles, update Civil Site Design and regenerate your corridors.


Templates provide an intuitive way to define your road, curb, sidewalks, pond elements and related grading strings. Civil Site Design provides a number of examples that can be easily configured to conform to your standards.

Automated Road Network Design

Once your alignments have been created, you can apply a template and generate the design for an entire subdivision with a single mouse click. You can also create all of your curb returns with a single mouse click saving you hours of effort when compared to native Civil 3D.​

This time saving process creates an initial vertical design for each road, applies your default template and allows you to view plan, profile and cross-sections simultaneously. All are tied together so changing the vertical design of one road updates all of the connected profiles.

Interactive, Intuitive Design Tools

The interactive design tools allow you to simultaneously access multiple windows of your design. You can open multiple profile views including curb returns and observe changes as a profile is updated. Same with cross-section views.

​The model viewer tool allows you to see the changes rendered in real time providing an intuitive perspective that helps experienced designers and greatly increases the productivity of new designers.

Real Time Interactive Visualization

The unique Model Viewer not only assists your design process with real time rendering and visualization, it has a number of powerful analysis tools including line of sight analysis and reporting, automated line marking which can be exported to your CAD drawing.

​For those who want to render a design for visualization, you can extrude buildings, insert objects like street lights and vehicles and much more.

Cul-de-Sac, Parking Bay and Roundabout Tools

Another productivity feature in Civil Site Design is the interactive cul-de-sac and roundabout network strings. These intuitive, form driven tools guide designers through the entire design process.

​Experienced designers can take full control of the design process making manual edits and controlling the design with their own alignments.

Civil 3D Design Exchange

If you are using Civil Site Design for Civil 3D, Civil Site Design will generate your profiles, design surfaces, corridors, assemblies and pipe networks for you. Never create or manage a corridor again!

Pipe Design

The pipe design module allows you to easily layout your design with simple polylines, will assign pipes and structures and will generate your network automatically.

The CSD pipe designer, provides a powerful interface that displays pipes in relationship to the ground surface. Pipes are designed automatically based on minimum slope and design flows. Obstructions from other utilities are displayed and color coated based on minimum clearances.

Incoming pipes are also displayed and will control the manhole invert where appropriate.
