About the Rendering Workflow
Lights and materials can be added to a 3D model before a photorealistic image is rendered
with the program’s renderer.
The following outlines the basic process of setting up a 3D model and rendering a
photorealistic image from a scene.
For information on rendering drawings that were originally setup in AutoCAD 2015-based
products and earlier, see “About Migrating 3D Models.”
