Activity 3 Creating a Sheet Metal Hinge

Overview

In this activity, you will construct several sheet metal features that are frequently used whenmanufacturing sheet metal parts. You will use some of the more advanced methods for

creating features in the Sheet Metal environment.

Objectives

After completing this activity, you will be able to:

Create basic sheet metal features like tabs and contour flanges. Use a sketch to create a contour flange. Properly orient a reference plane when using the Contour Flange command. Use the Unbend and Rebend commands. Place cutouts on unbent faces. Mirror features on a sheet metal part.
