Modern civil engineering projects often involve far more than just terrain and corridor models. Designers regularly work with a wide range of 3D CAD geometry, including utility models, structures, architectural elements, bridges, retaining walls, and other project assets.

With Civil Site Design v27, visualisation and sectioning capabilities have been significantly expanded, allowing users to seamlessly integrate native CAD 3D geometry directly into their design workflows.

The result is greater project context, improved design validation, and more comprehensive project reviews.

Expanded Support for Native CAD 3D Geometry

Civil Site Design v27 now supports the visualisation and sectioning of a broad range of native CAD 3D entities alongside Civil Site Design models.

Supported geometry includes:

  • 3D Polylines

  • 3D Solids

  • Polygon Meshes

  • 3DFaces

This expanded compatibility enables designers to work with a much richer representation of the project environment without needing to convert geometry or rely on external workflows.

See Your Entire Project in Context

One of the biggest challenges in design review is understanding how multiple project elements interact within the same space.

By bringing native CAD geometry into Civil Site Design’s visualisation tools, designers can now view roads, surfaces, drainage infrastructure, structures, and other project assets together in a single environment.

This creates a more complete picture of the design and helps identify potential issues earlier in the project lifecycle.

Whether reviewing site constraints, coordinating infrastructure, or validating design outcomes, having all relevant geometry visible in one place improves decision-making and reduces uncertainty.

Enhanced Model Viewer Integration

The expanded geometry support is fully integrated into the Model Viewer, allowing users to visualise native CAD objects alongside Civil Site Design models in a rich 3D environment.

This provides a more realistic representation of the overall project and helps teams better understand how design elements interact within the broader site context.

The ability to combine engineering models with CAD geometry makes the Model Viewer a more powerful design review and presentation tool.

Improved Vertical Grading Workflows

Native CAD geometry can also be visualised directly within the Vertical Grading Editor (VGE).

This enhanced visibility provides additional context when developing grading solutions and reviewing vertical design relationships.

Designers can assess grading outcomes against surrounding infrastructure and project elements, helping to improve coordination and reduce design conflicts.

More Powerful Quick Sections

Quick Sections have also been enhanced through support for native CAD geometry.

Users can now section through both Civil Site Design models and supported CAD entities within the same workflow, creating a more complete understanding of how various project components interact.

This is particularly valuable when reviewing:

  • Utility corridors

  • Structural interfaces

  • Drainage infrastructure

  • Complex urban environments

  • Multi-disciplinary project models

By incorporating additional project geometry into section views, designers gain deeper insight into the overall design.

Better Coordination Across Disciplines

Civil projects increasingly rely on collaboration between multiple disciplines, each contributing different model types and geometry.

The ability to visualise and section native CAD objects alongside Civil Site Design models helps bridge these workflows by providing a shared environment for design review and coordination.

This reduces the need to switch between platforms and improves communication across project teams.
