Model trimming is an essential part of refining and managing civil design models. Whether extending corridors, adjusting design limits, or refining project extents, trimming workflows have traditionally required users to navigate through dialogs and manually enter chainage values before seeing the results.

With Civil Site Design v27, model trim editing becomes a far more intuitive experience.

The introduction of interactive visual trim grips allows designers to edit trim extents directly within the drawing, providing immediate visual feedback and a significantly faster workflow.

Move Beyond Manual Chainage Entry

Traditionally, modifying model trims required opening the Model Builder dialog, locating the relevant trim settings, and manually entering chainage values.

While effective, this workflow often involved trial and error as users adjusted values and regenerated models to achieve the desired result.

Civil Site Design v27 replaces this process with a visual editing experience that allows users to work directly within the drawing environment.

Edit Trims Directly in the Drawing

The new visual trim grips provide a simple and intuitive way to manage model extents.

Rather than entering numerical values, users can simply select and drag trim grips to update trim locations on the fly.

As the grips are adjusted, the trim extents update immediately, making it easier to visualise changes and achieve the desired result more quickly.

This direct interaction dramatically reduces the number of steps required to modify a model.

Instant Visual Feedback

One of the biggest advantages of the new workflow is the ability to see changes as they happen.

By editing trims directly within the drawing, designers gain immediate visual confirmation of how the model is being modified.

This makes it easier to:

• Refine model extents

• Adjust design limits

• Validate trimming locations

• Make quick design changes

• Reduce unnecessary regeneration cycles

The result is a more efficient workflow that keeps designers focused on the model rather than the settings behind it.

Full Trim Management from the Toolspace

In addition to the new visual grips, Civil Site Design v27 provides comprehensive trim management tools within the Toolspace.

Users have complete control over:

• Adding new trims

• Editing existing trims

• Removing trims

• Managing trim configurations

This centralised approach ensures that trim editing remains both flexible and easy to manage, regardless of project complexity.

Faster Model Refinement

As projects evolve, model extents often require regular adjustments.

The ability to modify trims directly within the drawing significantly speeds up this process by reducing the need to move between dialogs and design views.

Whether refining a corridor model, adjusting a road design, or managing project boundaries, visual trim editing helps users make changes more efficiently while maintaining full control over the design.

Designed for a More Intuitive User Experience

The introduction of visual trim grips reflects a broader focus within Civil Site Design V.27 on creating more interactive and user-friendly workflows.

By bringing editing tools directly into the drawing environment, designers can interact with their models in a more natural way, reducing complexity and improving productivity.

The result is a workflow that feels faster, more responsive, and easier to use.

Key Benefits of Interactive Trim Editing

• Edit trims directly within the drawing

• Eliminate manual chainage entry

• Drag-and-drop visual trim grips

• Instant visual feedback

• Faster model refinement

• Simplified workflow for adjusting design extents

• Add, edit, and remove trims through the Toolspace

• Improved productivity and usability

A More Interactive Approach to Model Editing

Interactive trim editing transforms a traditionally dialog-driven task into a visual design workflow.

By allowing designers to manipulate trim extents directly within the drawing, Civil Site Design V.27and Corridor EZ makes model refinement faster, easier, and more intuitive than ever before.

Whether making minor adjustments or managing complex project extents, visual trim grips provide a more efficient way to interact with your models.
