From Your Desk, It’s Your Revit Live Model!

Revit Live immerses you within your building models. Instead of rendering the old-fashioned way, you can use the real-time rendering of Revit Live.

Getting Started in Revit Live

Autodesk Revit Live is essentially a real-time rendering program. It is a cloud-based service that allows Revit users to immerse themselves in their models. This helps designers better understand and explore their building models.

Preparing the Model

When preparing any view to be rendered, you want to make sure that everything has been modeled properly and the correct materials have been assigned to model elements. You also want to make sure that only the elements you want to see are visible in the view. These same rules apply for Revit Live. However, you can only send 3D views to Live.

Sending a Model to Revit Live

Once you are ready to take your model to Revit Live, there are a few things to keep in mind. Most importantly, the active view must be a 3D view. Additionally, here are some best practices:

  • Only elements in the current phase will be included
  • Only materials shown in the Realistic and Ray Trace visual styles will be shown
  • Set the Detail Level to Fine to ensure visual quality and optimal door animation

To take a model to Live, switch to the View ribbon. After you install Revit Live, a Go Live button will be available in the Presentation panel. Click Go Live to open the Go Live dialog. In this dialog, you can see the Project: and View: at the top. Below that, there will be a list of any errors or warnings. For example, if the current view is not a 3D view, an error will appear, stating that the active view is not a valid 3D view.

When an error appears, you will not be able to take the model live. But, when warnings appear, you can still take the model live. These warnings are there to help you understand the settings that will affect the quality and appearance of the model in Live. The warnings will likely relate to the best practices listed above.

For example, if the Visual Style is set to Shaded in Revit, the warning simply states that the model may appear differently in Live because it only uses materials that are shown in the Realistic and Ray Trace visual styles.

There is also an option under Advanced Options to extend the terrain to the horizon. When this is selected, the topography will extend to the extents of the view in Live. In a Revit 3D view, you can see the edges of a toposurface when zoomed out. When Extend terrain to horizon is selected, the topography never really ends for the sake of the view.

Additionally, you can specify the path where you want to download the Revit Live model. When you send a model to Live, an .lvmd file will be created.

To send the model to Live, click Go. When you do, a dialog appears, showing the status of the upload. Once it is finished, the .lvmd file will be available in the location that you specified. You can click Locate in the dialog to open the folder where the file is located. Or, you can click Open to open the model in the Revit Live Editor.

Viewing a Model in Revit Live

After a model is sent to Live, you can open it in the Revit Live Editor. Or, if you have an .lvmd file, you can open it at any time with the Revit Live Editor. When viewing a model, there are basically two navigation modes: Orbit and Tap & Go. When in Orbit mode, you can view the model similar to how you would in Revit. You can simply hold the left mouse button and then move the cursor in the direction you want to orbit the model.

To switch to Tap & Go mode, you can click the button at the bottom of the view window, or you can click a point in the model while in Orbit mode. Then the camera will move to that location and the mode will switch to Tap & Go.

When in Tap & Go mode, you can also hold the left mouse button and move the cursor in order to move the camera. You can also click a point and the camera will move to that location. And not only will it move to the point you clicked, but the camera path to get there will walk through any doors and go up or down stairs.

Additionally, you can use the W, A, S, and D keys to walk around the model. The cool thing about walking around a model is that you cannot walk through walls. You must enter buildings or other rooms through a door, just like you would in real-life!

Views can also be created in Live so that you can quickly switch to a specific viewpoint. When a model has several 3D views in Revit, those views become views in Live.

Understanding View Settings in Revit Live

In Revit Live, you can adjust several settings. For example, you can adjust the Sun Position, which is controlled by the date and time. You can also control graphic settings, lighting settings, and navigation settings to help meet your needs and presentation requirements.

Furthermore, you can use the Info tool to select elements to view information about that element. The parameters that are shown come from Revit. Not every single parameter displays, but the information can help you identify why something may not be modeled the way it should. Or, the information can provide additional details about a portion of the building model.

Go Live!

If you have not tried Revit Live, you can get a 30-day trial and try it for yourself. This cloud-based, immersive tool can help you explore your designs in a new way. And you can even use a VR headset to further immerse yourself within a model!
