Advanced Settings#

Advanced Settings allow a “One-Click” export experience with fully customizable settings. These settings are saved internally to the Revit file, so all members of the Project Team can export in the same way. Additionally, Advanced settings allow for a Project or BIM Manager to set an override .json file to control a subset of export settings across projects.

Standard Options	Result
Include Cameras	When checked, all elevations in the Revit model are exported as cameras
Include Lights	When checked, Revit Light objects are exported
Include Vegetation	When checked, all plants in the Revit model are exported
Include Rooms	When checked, exports rooms within the model as mesh volumes colored by selected color scheme.
Include Spaces	When checked, exports spaces within the model as mesh volumes colored by selected color scheme.
Include Drawings	When checked, exports drawings from selected Publish Set as textured mesh planes anchored at real-world scale to the model.
Enable Family Instancing	When checked, export Revit Family objects
Enable Logging	When checked, a log is created and a dialog displaying any errors or warnings is shown after export
Include BIM Information	When checked, parameters of Revit elements are exported as USD properties
Include Links	When checked, linked Revit models are included in the export
Use Revit Materials	When selected, use the rendering assets of Revit materials
Use Material Mapping	When selected, mapped materials are used in place of Autodesk rendering assets.
Prop Export	When selected, Revit model is exported with Prop Workflow
Project Export	When selected, Revit model is exported with Project Workflow

View Options	Result
View Name	3D Revit View to export
Detail Level	Set the detail level to be temporarily applied to the view during export
Phase Filter	Set the phase filter to be temporarily applied to the view during export
View Template	Set the view template to be temporarily applied to the view during export
Coordinate System	Set the coordinate system to be used during model export

Output Options	Result
Output Folder	Select a folder for the export
File Name	Specify the name and usd extension of the file. Tokens may be used as variables in the file name.
Global Json	Optionally select a .json file to override some of all of the Advanced Settings

I/O	Result
Import Json	Select a .json file to import and apply its settings
Export Json	Save the current advanced settings as an external .json file
Save	Save the current advanced settings internally into the Revit model (Revit file must be Saved/Synced for settings to persist)

Scene Optimization#

Scene Optimization utilizes core optimization libraries found in the standalone application and kit extension that performs scene optimizations at the USD level. This allows complex scenes to be converted into more lightweight representations which can be displayed and evaluated more quickly.

The integration provides various processes which can be used individually or in combination stack to optimize a scene. A few base configurations have been provided in the connector to optimize the data prior to sending to Omniverse USD Composer.

To use a different optimization preset, click > + then navigate to the desired json configuration file.

Please see the Scene Optimizer user manual for information on the optimization operations and how to create custom configuration files.

Note

Merging texture based materials is not currently supported, only base colors.

Export By Selected Views#

With this setting checked, users can export views within a single Revit files as separate USDs. Depending on whether the user has selected prop or project export, the USDs are combined into a single project or not.

This feature is intended for models whose elements are separated by views showing worksets, phases, or other forms of categorization set by the user.

../../_images/revit_release-notes_108_2_2211_4ExportBySelectedViews.png

Similar to the Batch export UI, users can select which views to export. For example, this Brownstone model has views separating interior, exterior and FF&E elements:

../../_images/revit_release-notes_108_2_2211_6SelectedViewsStep1.png

When exported as a project to Omniverse, elements in views are exported as separate USD files and combined into a single project (viewed in Omniverse USD Composer):

../../_images/revit_release-notes_108_2_2211_6SelectedViewsStep2.gif

Additional Notes#

If an element is shown in multiple views, it will be exported to each USD representing that view.
Names of exported views take the provided name of the file in the export UI + the name of the view.

Export Log#

With logging enabled in settings, warnings and errors encountered in export as surfaced in a simple UI after export. This can provide some clarity on elements which failed to convert.

Note

Logs are saved in %localappdata%NVIDIA CorporationOmniverseLogs

Drawing Export#

With this setting checked, you can now export drawings from Print Sets as textured mesh quads which are anchored in place to their respective areas.

../../_images/revit_release-notes_108_2_2228_drawings.png

To create a print set, open the Print dialog in Revit. You have the ability to choose which print set’s drawings you would like exported to the model.

../../_images/revit_release-notes_108_2_2228_printSets.png

Drawings must have crop regions in their view in order to anchor to the model. If a drawing wasn’t successfully exported, this is because the drawing did not possess a crop region.

Drawings are located in the USD hierarchy under the path World/{modelName}/Media/Drawings , which is invisible by default.

../../_images/revit_release-notes_108_2_2228_elevation_trans2.png

Use drawing export in combination with the Section widget in Omniverse USD Composer to bring your floorplans to life:

../../_images/revit_release-notes_108_2_2228_drawings_gif.gif

Additional Notes#

Transparency can be applied in images in Omniverse USD Composer by modifying the material.

Room & Space Export#

You can now check Include Rooms and Include Spaces in the settings window. This will export these areas as volumes.

Rooms and spaces are located in the USD hierarchy under the path World/{modelName}/Geometry/Rooms , which is invisible by default.

../../_images/revit_release-notes_108_2_2228_roomVolumes.png

In versions 2022 and later, you can select a color scheme with which to color the exported rooms - this will create new materials in your USD.

../../_images/revit_release-notes_108_2_2228_roomScheme.png

Additional Notes#

Volume of room object may be smaller than the volume of the room.
If a valid color cannot be generated, a random or default one is assigned.
