Revit¶

Overview¶

The OMNIVERSE® REVIT CONNECT® Plug-In offers a simple toolkit for Revit Users to send and live sync their model data to an Omniverse Nucleus. This not only gives Revit users a first class renderer through Omniverse View or Omniverse Kit but also the ability to open, edit and sync with any of the NVIDIA Omniverse™ Connect applications. Now, depending on the use case, Revit users can choose the workflows and pipelines that work best for their needs while maintaining up to date revisions for all downstream consumers of their work.

Install Instructions¶

Please see Launcher Documentation for Installing Connectors.

User Interface¶

The Omniverse Revit Plugin brings Revit into the Omniverse Platform through the use of NVIDIA Omniverse™ Connect tools similar to other NVIDIA Omniverse™ Connect applications.

With the Plugin installed, Revit should display an Omniverse Menu now visible in the top menu.

Clicking this menu will reveal the ribbon panel for Omniverse Interactions.

Settings¶

The settings menu allows you to select a preferred View install as your viewer.

Note

You will need to have View installed and selected to use Send to View.

Setting	Result
Enable Cache	Enables and Disables File Caching, Enabled improves performance.
Auto Sign-In on Startup	Automatically sign into the last user during the Revit Launch processes.
Unset	No View Settings (This setting disables Send to View)
Send to Local	Omniverse View Launch Path
Automatic Local	Locates View Installs Automatically, “Use Current” Always Uses Most Recent Install
Custom View Location	Allows Selections of View Installs not Found by Automatic
Send to Server	Omniverse View Launch Path on a Remote Server
Automatic Server	Automatically Finds Servers
Remote Launcher	Alows for Slection of a Specified Remote Server
Render Size	Render Quality to Use in View when Launching Remotely
Save	Commits the Changes and Closes the WIndow
Cancel	Closes the Window and Discarding the Changes

Send to View¶

Sends your file directly to Omniverse View. Simply click “Send to View” and Omniverse View will launch with your model loaded and ready to go.

Note

You must be sure that Omniverse View is installed or that you can access it from a server for this feature to work. See Settings for more details.

Send to View (Video)¶

Sign-In Window¶

The sign in window allows users to connect to their NVIDIA Omniverse™ Nucleus Server for Exporting, using Live Sync and for Mounts. Simply enter your NVIDIA Omniverse™ Nucleus “User Name” and “Password” to sign into your NVIDIA Omniverse™ Nucleus.

Setting	Result
User Name	Omniverse Nucleus Username
Server	Address of Omniverse Nucleus Server
Sign-In	Begins the Connection with Selected User/Server
Cancel	Stops the Sign-In Process and Closes the Sign-In Window

Note

If you have trouble logging into Omniverse via the Revit Plugin, try Launching Revit as Administrator.

Live Sync¶

Live sync updates your models allowing other Omniverse applications get your changes in real-time.

Setting	Result
Live Sync	Toggle to enable / disable live sync on current file.
Live Sync Dropdown	Live Sync All: Syncs everything in your scene. Live Sync Selected: Only syncs the selected object(s). Live Sync Visible: Only live syncs assets that are visible in the viewport.
Path	When connected to a file, will show path to linked file.

Export¶

Exporting your project to your NVIDIA Omniverse™ Nucleus allows you to continue your work in other Omniverse Apps and connectors.

Note

When you export your file, you create a connection for Live Sync which is visible in the Live Sync Path dialogue.

Materials¶

When sending your materials to Omniverse View, we replace the low quality textures and shaders associated with Revit and replace them with High Quality Custom Materials inside of Omniverse View. This is done by material mapping and can be controlled via CSV.

CSV and Materials¶

The CSV Mapping File for Revit can be located in the following directory.

<Documents>/Omniverse/Revit/omniverseMDLtable.csv

CSV File Structure¶

A CSV file is a Comma Separated Values table of data whose field’s end is defined by a comma ‘,’.

Using Spreadsheet Tools¶

These tables are a very common format and can be opened/edited inside of Excel (or other spreadsheet tools) and will have 5 columns in them when viewed.

Format¶

Column	Expected Value
Column A	Name of the material from the application. Note: Any commas (`,`) are replaced with an asterisk (`*`)
Column B	Indicates if there is a parameter override \| NONE: default, no special characteristics \| COLOR: the 5th column (Column E) will have the parameter name in the MDL GENERIC: keyword and last resort match in mapping (looks for the value in Column A in the string of the material name we get from the application e.g. if Column A is glass and the material from Revit was Special Glass then it would match) EXCLUDE: materials found in the application but NOT mapped, user could convert these to real mappings by setting to NONE and changing the values in Column C/D/E (potentially)
Column C	MDL name (no .MDL)
Column D	Path into the location in the Omniverse database (points to a Mount)
Column E	If necessary, the parameter override in MDL

Examples¶

Cardboard,NONE,Cardboard,/NVIDIA/AEC/Library/Materials/Wall_Board
Blue Paint,COLOR,Paint_Satin,/NVIDIA/AEC/Library/Materials/Miscellaneous,diffuse_tint
glass,GENERIC,Clear_Glass,/NVIDIA/AEC/Library/Materials/Glass
Some Material Name,EXCLUDE,WhiteMode,/NVIDIA/AEC/Library/Materials/Styles
