Setting cable tray material in Revit

In Revit, cable trays do not have a native material parameter, so materials are assigned globally via Object Styles or through project/shared parameters combined with view filters.

Method 1: Using Object Styles

Revit allows you to set a global material for all cable trays in a project:

1. Go to the Manage tab.
2. Click Object Styles.
3. Navigate to the Cable Tray & Cable Tray Fittings category.
4. Assign the desired material. This method affects all cable trays in the project uniformly, including floor plans, sections, 3D views, and Navisworks exports .

Method 2: Using Project or Shared Parameters

For more granular control, you can create a custom material parameter:

1. Go to Manage → Project Parameters → Add.
2. Create a new parameter, e.g., Cable Tray Material, and assign it to the Cable Tray category.
3. Once added, each cable tray instance will have this property in its Properties palette.
4. While Revit does not display the material visually in the model, this information can be exported to Navisworks or used in schedules .

Method 3: Using View Filters

To differentiate cable trays by type or service:

1. Assign a Service Type or custom parameter to each cable tray.
2. Create view filters based on this parameter.
3. Apply color or line pattern overrides in the view to visually distinguish cable trays. This approach allows different cable trays to appear with distinct materials or colors in specific views without affecting the global Object Styles .

Notes and Best Practices

• Cable trays in Revit do not support system-based material overrides like ducts or pipes, so filters or parameters are necessary for differentiation .
• For IFC exports, using the IfcSingleMaterialOverride parameter with Service Type ensures consistent material assignment across software platforms .
• Combining shared parameters with view filters provides the most flexible solution for large projects with multiple cable tray types . By using these methods, you can manage cable tray materials effectively in Revit, either globally or with more detailed control for visualization, documentation, and coordination purposes.
