Example: Creating a Shell Feature
This example shows creating a shell feature. The original body is shown in the following illustration.
1. Click > 
Shell. The system applies a default thickness on the inside of all the surfaces, creating a closed shell, and displays the preview geometry.

3. To modify the shell thickness, type 1 in the Thickness box on the Shell tab. The system updates the preview geometry.
4. To specify that the bottom surface should have a different thickness, on the References tab, click the Non-default thickness collector, and select the bottom surface. The surface name and thickness value (initially equal to the default shell thickness) is added in the Non-default thickness collector.
5. Click the thickness value box in the Non-default thickness collector and type 2 to specify the thickness at the bottom. The system updates the preview geometry.
6. Click 
OK. The final geometry is shown.
