AutoCAD 3D Modeling: Render Window

February 24, 2004

The output image of the render operation can be diverted to a special window called Render Window. You can use the Render Preferences dialog box and alter the destination to Render Window. The following tutorial shows you how to benefit from the window.

Note: This tutorial is designed for AutoCAD 2004 though might be applicable to other releases.

1. Download and then open r16_render_window.dwg. The file contains the model of an armchair on a flat circular plane [Figure 1].

Note: If you are using AutoCAD 2002 or an earlier release download r15_render_window.dwg.
