To change how the phases of a linked Revit model are interpreted and displayed within your host model, you need to adjust its Phase Mapping settings. This ensures that elements from the linked model appear correctly according to the phases defined in your host project.
Understanding Phase Mapping for Revit Links
When you link a Revit model into your project, its internal phases (e.g., Existing, New Construction) are not automatically aligned with the phases in your host model. Phase mapping provides a crucial mechanism to establish a relationship between the host model's phases and the linked model's phases. This allows you to control which elements from the linked model are visible in different phases of your host model, ensuring proper coordination and graphic representation. It's important to note that this process doesn't alter the phases of elements within the linked file itself, but rather how your host model interprets those phases.
Step-by-Step Guide to Changing Linked Model Phase Mapping
Adjusting the phase mapping for a linked Revit model is done through its Type Properties in the host model. Follow these steps to configure the phase relationships:
1. Select the Linked Model
Begin by opening your host Revit model.
- In the drawing area of your host model, select the linked Revit model. You can do this by hovering over the link and clicking when it highlights.
2. Access Type Properties
Once the linked model is selected, you'll need to open its Type Properties.
- With the linked model selected, navigate to the Modify | RVT Links tab on the Revit ribbon.
- In the Properties panel, click (Type Properties). This will open the Type Properties dialog box for the linked model.
3. Locate Phase Mapping Parameter
Inside the Type Properties dialog, find the parameter responsible for phase interpretation.
- In the Type Properties dialog, locate the Phase Mapping parameter.
4. Edit Phase Mappings
To configure the phase relationships, you'll need to open the dedicated dialog.
- Click the Edit button associated with the Phase Mapping parameter. This will open the Phases dialog.
5. Define Mapping Options
This is where you establish the correspondence between your host model's phases and the linked model's phases.
- In the Phases dialog, you will see a list of phases from your host model. For each host phase, you will select the appropriate corresponding phase from the linked Revit model.
- For example, you might map your host model's "New Construction" phase to the linked model's "New Construction" phase. This ensures that elements designated as "New Construction" in the linked file are displayed when your host view's phase is set to "New Construction."
Here’s a common example of how phases might be mapped:
| Host Model Phase | Linked Model Phase (Mapped To) | Description |
|---|---|---|
| Existing | Existing | Shows linked elements phased as Existing when the host view is set to Existing. |
| Demolished | Demolished | Displays linked elements marked for demolition in the host's Demolished phase. |
| New Construction | New Construction | Renders linked elements phased as New Construction when the host view is set to New Construction. |
| Future | Future | Useful for multi-phase projects, mapping host future to linked future elements. |
6. Confirm Changes
After defining all the necessary phase mappings, apply your settings.
- Click OK in the Phases dialog to save your mapping selections.
- Click OK in the Type Properties dialog to apply the changes to the linked Revit model type.
Practical Considerations and Best Practices
- Consistency is Key: For seamless coordination and clear visual representation, it's crucial to have consistent phase naming and usage across all linked models and your host model. Discrepancies can lead to elements appearing incorrectly or not at all.
- Impact on Visibility: Phase mapping directly affects the visibility of elements from the linked model. If elements are not mapped correctly, they might not display in your views even if they are present in the linked file.
- Graphic Overrides: Remember that phase mapping works in conjunction with Phase Filters and Graphic Overrides in your host views. Ensure your view's phase filter settings allow the desired linked elements to be shown.
- Type vs. Instance: Phase mapping is a Type Property of the linked Revit model. This means that if you have multiple instances of the same linked model type, changing the phase mapping for one will affect all instances of that type. If you need different phase mappings for different instances of the same model, you might consider creating duplicate types or using workarounds like separate link files if applicable.
By correctly configuring phase mapping, you can effectively manage the display and coordination of complex projects involving multiple Revit models, ensuring all components are viewed in their intended phase contexts.
