Shell Definition
Use Refine Model > Shell to define a simple or advanced shell on a model surface. Simple shells differ from advanced shells in this way:
Simple—A simple shell is of uniform thickness. If you select Simple as the shell type, you can define a thickness and a material for the shell.
Advanced—An advanced shell can be homogenous, or have laminated properties. If you select Advanced as the shell type, the software displays fields prompting you to define its shell property, material, and material orientation.
When you click Refine Model > Shell, the Shell Definition dialog box opens, which includes:
Name—Specify a name for the shell. The software provides default names, such as Shell1, Shell2, and so on. You can change these default names to more meaningful names if you like. The name you specify should be unique. The color swatch adjacent to Name allows you to change the color of the shell and the text displayed for the shell.
References—Specify the surfaces associated with the shell. If you select a valid surface or surfaces for the shell and then click Refine Model > Shell, your selections appear in the References collector when the Shell Definition dialog box opens. You can change the normal direction of the shell, when you select the surface. Do not select the same reference twice. You cannot select suppressed references.

The software shares data across several selected surfaces or quilts. Therefore, if you change data on one surface or quilt with shared data, the others will be affected as well.
Type—Specify either Simple or Advanced. The remaining fields on the dialog box change depending on your selection.
