After rendering a 3D view, you can export the image to a file. This file is stored outside the project in the specified location. 
 Revit supports the following image file types: BMP, JPEG, JPG, PNG, and TIFF. 
Note: To preserve the alpha channel for transparency, use the PNG or TIFF file format. If you plan to use the exported image in Adobe® Photoshop®, export to TIFF for best results. (If you export to PNG and open the file in Adobe® Photoshop®, the background sky and clouds may not display.) 
To export the rendered image
- In the Rendering dialog, under Image, click Export. 
 
- In the Save Image dialog, for Save in, navigate to the desired location. 
 
- For Files of type, select a file type. 
 
- For File name, enter a name for the image file. 
 
- Click Save.
