Revit cable tray annotation

Cable tray annotation in Revit allows you to display sizes, fittings, and connectors clearly, with options for automatic tagging and custom symbols.

Cable Tray Settings

Revit provides a Cable Tray Settings pane where you can control how annotations appear in your project. Key parameters include:

• Use Annot. Scale for Single Line Fittings: Determines whether fittings are drawn according to the Cable Tray Fitting Annotation Size parameter. Changing this does not affect already placed components .
• Cable Tray Fitting Annotation Size: Sets the plotted size of fittings in single-line views, maintaining consistent display regardless of drawing scale .
• Cable Tray Size Separator: Defines the symbol used to separate width and height in the annotation (e.g., 12" x 4"), .
• Cable Tray Size Suffix: Adds a symbol or text after the size for clarity .
• Cable Tray Connector Separator: Specifies the symbol used between different connectors . These settings ensure that your cable tray annotations are consistent and readable across different views and scales.

Tagging Cable Trays

To annotate cable trays in Revit:

1. Go to the Systems tab and select Electrical → Cable Tray.
2. Choose the desired type from the Type Selector, with or without fittings.
3. On the Options Bar, set width, height, offset, or bend radius.
4. Ensure Tag on Placement is selected to automatically tag the cable tray as you place it . This method allows for automatic annotation of cable trays, reducing manual work and improving documentation accuracy.

Plugins for Enhanced Annotation

For more advanced annotation, plugins like WireInConduit can automate cable tray labeling:

• Automatically generates wiring annotations based on electrical circuits.
• Calculates cable quantities and configures each type of wiring.
• Provides descriptions for cable types and behavior without using a standard template.
• Compatible with Revit 2019–2027 . Additionally, tools like CableTrayAnnotationHelper (for Revit 2025) can further streamline annotation tasks, especially in large projects .

Best Practices

• Use consistent symbols and separators for sizes and connectors to maintain clarity.
• Apply annotation scaling to ensure readability in different view scales.
• Consider plugins for projects with complex wiring to save time and reduce errors.
• Regularly check that tags are updated when modifying cable tray dimensions or fittings. By combining Revit's built-in annotation tools with optional plugins, you can create accurate, clear, and automated cable tray documentation for MEP projects.
