Revit cable trays come in multiple colors

Revit cable trays can be displayed in multiple colors using Object Styles, the Paint tool, or View Filters, with material overrides required for consistent export to Navisworks or IFC.

Changing Cable Tray Colors in Revit

1. Object Styles (Global Category Color): To change the color of all cable trays in a project, go to Manage > Object Styles > Model Objects tab, locate Cable Tray, and click the color box to select a new color. This affects all instances of cable trays in the project . 2. Paint Tool (Individual Tray Color): For selective coloring of specific cable trays, use the Paint tool. This allows you to apply a different color to individual trays without affecting the entire category . 3. View Filters (Conditional Coloring): You can create View Filters based on parameters such as Service Type. Assign the filter to a view and set the surface pattern or color. This method is useful for differentiating cable trays in coordination or electrical drawings . Filters are ideal for visual distinction but do not carry through to IFC exports unless materials are applied directly .

Export Considerations

• Navisworks: Only recognizes materials, not filters or system overrides. To maintain colors in Navisworks, assign a material to each cable tray or create a selection set in Navisworks .
• IFC Exports: Use IfcSingleMaterialOverride with materials generated based on Service Type. This ensures that colored trays appear correctly in IFC files. It may require duplicating tray types for each service type to automate material assignment .

Best Practices

• Use Object Styles for consistent project-wide color schemes.
• Use Paint tool for exceptions or highlighting specific trays.
• Use View Filters for visual differentiation in documentation.
• Apply materials for reliable export to Navisworks or IFC.
• Consider setting Service Type at the type level to automate color assignment and reduce manual updates . By combining these methods, you can achieve both clear visual differentiation in Revit and maintain color consistency in exported models.
