Render the view to create a photorealistic image of the 3D model.
Before starting the render process, see Best Practices: Rendering for information about how you can improve performance.
After preparing the 3D view and using the Rendering dialog to select desired settings, click Render to render the image.
Revit begins the rendering process, rendering the entire image progressively. Revit displays a progress dialog, which shows information about the rendering process.
When the rendering process is complete, Revit displays the rendered image in the drawing area.
You can then do the following:
In the Rendering dialog, click Show the model. To display the rendered image again, click Show the rendering.
