The screen shots and videos below show the functionality operating on Civil Site Design. The same functionality is accessible in Corridor EZ.
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 the need to constantly switch between different views and dialogs.
This approach not only streamlines the design process but also enhances overall usability, making complex tasks more accessible to a wider range of users.
Enhanced Productivity and Accuracy
The ability to perform real-time adjustments with visual feedback means that designers can achieve greater precision and accuracy in their model trimming.
Errors are minimised, and the design intent is more easily maintained, leading to higher-quality outputs and reduced rework.
The interactive nature of the new tools also encourages experimentation, allowing designers to explore different trimming scenarios quickly and efficiently.
Seamless Integration with Existing Workflows
The new interactive trim editing features are seamlessly integrated into the existing Civil Site Design environment, ensuring a smooth transition for current users.
Designers can continue to leverage their familiar workflows while benefiting from the added efficiency and intuitiveness of the new tools.
This integration ensures that the enhancements complement, rather than disrupt, established design practices.
Looking Ahead: The Future of Civil Site Design
The introduction of interactive model trim editing in Civil Site Design v27 is a significant step forward in making civil design software more intuitive and powerful.
As technology continues to evolve, the focus will remain on developing tools that enhance user experience, streamline workflows, and ultimately empower designers to create better, more efficient civil infrastructure.
By embracing interactive and visual approaches, Civil Site Design is committed to delivering innovative solutions that meet the evolving needs of the civil engineering community.
