Defines the name, classification, symbol definition, and preview graphic for the new part class.
Name
Specify a unique name for the new class to identify the part class in the catalog schema. If you are using Microsoft SQL server, the part class name cannot exceed 31 characters. If you are using an Oracle database, the maximum number of characters is 23. Do not use special characters such as spaces < > . - ! ? + ' % , ; | & ~ * / \ $ in the names of part classes.
Display Name
Specify a name to use in the tree view for the part class.
Classification
Select the part classification. Part classifications define the minimum required interfaces for the new part class.
The part classifications that are available to select from are defined in the Part Class Types select list. You can edit that select list to include additional part classifications, if needed. The software suggests a default classification based on the current node selection in the tree view. In some cases, such as under the Equipment node, the software will not be able to default this option.
Symbol Definition
Specify the symbol or SmartAssembly ProgID that represents the new part class.
If you are using a custom symbol, you need to get the symbol definition name from the person who created the symbol. The symbol definition that you need to enter here is indicated by the red arrows.
Preview Graphic
Specify the .bmp, .jpg, or .gif graphic to display when you click the Preview Command 
on the ribbon.
If you are using a delivered symbol, the preview graphic name is usually taken from the text that comes before ".ingr" as the symbol's ProgID name. For example, if the symbol ProgID is SP3DReturn,Ingr.Content.Piping.Return, then the preview graphic is SP3DReturn.gif.
If you are using a custom symbol, the graphic must be in the [ProductFolder]\SharedContent\SymbolIcons folder. We recommend that you use the same naming convention as the delivered symbols to limit confusion.
Copy From
Click to use an existing part class as the basis for the new part class. All of the existing part class information, classification, symbol definition, and symbol occurrence information in copied into the dialog.
