About Defining Bulk Item Parameters
You can create, modify, and delete parameters using the Parameters dialog box. The work flow for manipulating bulk item parameters is identical to other parameter operations within Part mode. However, the following additional functionality is added to bulk item parameters:
• In the Parameters dialog box, click Properties. The Parameter Properties dialog box opens. To specify if a bulk item parameter requires user input select User Input. This requires you to provide data when bulk items are placed in an assembly. Parameter input is performed from the Bulk Component dialog box.
• Bulk parts have a default parameter named BOM_REPORT_QUANTITY. The number value for this parameter is the quantity for the bulk item part in the Bill of Materials (BOM).
• You can define the following additional parameter types for bulk items:
◦ Length Measure—Supplies the value of the parameter by calculating the length of the specified curve or edge. The curve is selected from the Bulk Component dialog when the value cell for the parameter is selected. The User Input check box is automatically selected when the Length Measure parameter is used.
◦ Distance Measure—Supplies the value of the parameter by calculating the distance between two specified entities. The two reference entities are selected from the Bulk Component dialog when the value cell for the parameter is selected. The User Input check box is automatically selected when the Distance Measure parameter is used.
◦ Diameter Measure—Supplies the value of the parameter by calculating the diameter of a specified circular curve or edge. The curve is selected from the Bulk Component dialog when the value cell for the parameter is selected. The User Input check box is automatically selected when the Diameter Measure parameter is used.
◦ Area Measure—Supplies the value of the parameter by calculating the surface area of a specified surface or collection of surfaces. The surfaces are selected from the Bulk Component dialog when the value cell for the parameter is selected. The User Input check box is automatically selected when the Area Measure parameter is used.
◦ Angle Measure—Supplies the value of the parameter by calculating the angle between two entities. The two reference entities are selected from the Bulk Component dialog when the value cell for the parameter is selected. The User Input check box is automatically selected when the Angle Measure parameter is used.
◦ Parameter Sum—Obtains values of the same named parameter from other objects in the assembly and sums up the total values of those parameters. The objects used to input values to this value are selected from the Bulk Component dialog when the value cell for the parameter is selected. The selected objects must have an existing parameter with the same name as the Parameter Sum parameter.
