Specific property data must be added to a part to provide a complete electrical definition. Property data can be added at the part level or on the part occurrence.
At the part level, there are no required properties that you must set. The part name and part number are automatically set based on the part file name and the Autodesk Inventor part number. If needed, you can set the reference designator (RefDes) property. Typically a generic or place holder value such as U? is set. Any properties set at the part level are also visible on the part occurrence in the assembly.
Once the part is added to a harness assembly, the RefDes is required for each occurrence of the part in the context of the assembly. The RefDes is the unique identifier that maps the part to the schematic, wiring diagram, or electrical connectivity data.
Additional custom properties can also be added to the part or the part occurrence. Custom properties are used to provide specific information to downstream users or downstream processes such as reporting. Custom properties, such as the vendor and vendor part number, often come from the data book for the component.
