Under a Part node or Local Part node you define and create a geometry sequence with geometric primitives and features as subnodes. The Settings window for a Part node is identical to the Settings window for a corresponding Geometry node of the same dimension, except that there is an Input Parameters section and no Automatic rebuild check box (see The Geometry Node).Enter the names of the input parameters (arguments) in the Name column. In the Default expression column, enter their default values as expressions in terms of global parameters and numerical values. The corresponding values appear in the Value column. Optionally, enter descriptions for the input parameters in the Description column.
