Revit automatically generates cable trays

Revit can automatically generate cable trays using tools like pyRevit scripts, Dynamo workflows, or specialized plugins such as EAE Cable Tray, which streamline layout creation and reduce manual modeling.pyRevit AutomationThe Revit Automation Trench Modeler is a custom pyRevit tool that generates cable trays from selected pipes and conduits. It intelligently calculates width, height, and elevation based on real project conditions, allowing dynamic creation of trays without manual adjustments, which is particularly useful for complex MEP coordination.

Dynamo Workflows

Dynamo can automate cable tray placement using data-driven approaches. For example, you can define start and end coordinates (XYZ values) and tray parameters like type, width, and height in an Excel sheet. Dynamo scripts then automatically create the cable trays in the Revit model, supporting multi-level projects and generating detailed layout reports.

This method is ideal for repetitive or large-scale projects.

Commercial Plugins

The EA

E Cable Tray Plugin integrates Revit with EAE Electric's cable management products. It allows users to: Draw cable tray routes and divide them into segmentsConvert routes into different product groups or sizesApply color-coded layouts for clarityAutomatically update tray parameters via a cloud-based system, ensuring the latest product data is used Benefits of AutomationTime-saving: Reduces hours of manual modelingAccuracy: Ensures correct dimensions and alignmentMulti-level support: Handles complex vertical and horizontal routingData integration: Supports Excel or cloud-based product data for dynamic updatesGetting StartedFor pyRevit, download the Revit Automation Trench Modeler from GitHub and follow the installation instructions.

For Dynamo, create or use existing scripts that read tray parameters from Excel and generate trays automatically.

For EA

E Plugin, register with EAE Electric and install the plugin to access up-to-date product libraries and automated routing features. By leveraging these tools, Revit users can significantly streamline cable tray design, improve coordination, and reduce errors in MEP projects.
