After rendering a 3D view, you can save the image as a project view. In a project, rendered images display in the Project Browser under Views (all) > Renderings. You can then place the rendered view on a sheet. 
Note: These images are saved as compressed, light-weight JPG files in draft views. This strategy is intended to reduce the total size of the project file. If you prefer high-quality images, use the Export option. 
To save the rendered image as a project view
- In the Rendering dialog, under Image, click Save to Project. 
 
- In the Save to Project dialog, enter a name for the rendered view, and click OK. 
 
- (Optional) Place the rendered view on a sheet.
