Revit lighting fixtures export light sources as geometry.

Issue

The current Navisworks exporter views lighting cones as geometry and exports the information as such. This extra geometry can be hidden at the Navisworks level, or hidden in your Revit model to prevent the information from exporting.

Solution

Manually Select and hide light Geometry:

This process will be useful for Navisworks models with fewer instances of lighting fixtures.

1. Open the model in Navisworks.
2. Locate and select the lighting fixture in your model.
3. Locate the selected item in the Selection Tree.
4. Expand the selection and locate the “Solid” item in the item related to the Light fixture.
5. Right-click the “Solid” entry and select “Hide”.
6. If your item is instanced multiple times, a dialog will display in reference to this. Click “OK” to hide all instances.

Globally find and hide light Geometry:

This process will be useful with Navisworks models that contain multiple instances of different lighting fixtures.

1. Open the model in Navisworks and access the “Find Items” tab.
2. Select the appropriate model(s) in the Search in: list.
3. Select a Category of “Revit Material”.
4. Select a Property of “Name”.
5. Select a Condition of “=”.
6. Select a Value of “Default Light Source”.
7. Click “Find All” to locate all the results in the Selection Tree.
8. Right-click a selection and click “Hide”.
9. If your item is instanced multiple times, a dialog will display in reference to this. Click “OK” to hide all instances.

Adjust the Geometry Family in your Revit Model

This process lets you adjust your model in Revit, so your export to Navisworks does not contain the lighting component.

1. Open your Revit Model.
2. In the Project browser click and expand Families > Lighting Fixtures.
3. Right-click the lighting fixture and click “Edit”.
4. A dialog will display to open the Family for edit. Click “and the family component will display.
5. Click Create > Category and Parameters and the Family Category and Parameters dialog will display.
6. Select “Lighting Fixtures” in the Family Category list.
7. In the Family Parameters list uncheck “Light Source”.
8. Click “OK”.
9. Click Create > Load into Project and the Family Already Exists dialog will display.
10. Click “Overwrite the Existing Version”.
11. Repeat this process for any remaining fixtures.
12. Export your model into NWC format.
