This tutorial is a quick review of different methods for viewing 3D models.

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

1. Download r16_3d_bed.dwg.

Note: If you are using AutoCAD 2002 or an earlier version, download r15_3d_bed.dwg.

13. Drag the mouse inside the arcball to rotate the model in 3D space. If you drag the mouse outside the arcball the model will rotate about an axis that is perpendicular to the monitor. Initiating the dragging from lower and/or upper small circles will rotate the model about the horizontal axis. Finally if you initiate dragging from circles to the sides of the arcball the model will rotate about vertical axis.
