AutoCAD 3D Modeling: Sections
August 28, 2003 The SECTIONS command enables you to create
regions through 3D models. You should define an intersecting
plane that passes through the model to generate the region. If
you select more than one solid model separate regions will be
created for every one of them.
Notes:
- This tutorial is designed for AutoCAD 2004 though might be
applicable to other releases.
- In this tutorial user entries are in boldface.
- The

symbol represents pressing Enter.
- To learn more on regions read
