Special Variables
Special variables let conditions check common file information without requiring a PDM variable.
The SOLIDWORKS add-in includes built-in values and custom properties available from the active document and its references. The dropdown only shows values available in the current document context.

Common special variables include:
FileNameFilePathFolderNameFolderPathConfigurationName
Use these when the condition depends on common file or configuration information. PDM values are available only when the add-in has an applicable PDM context and the value appears in the menu.
