My task is to find the mass and COG of our modeled harnesses. I take it from the response that assigning mass to wires is not supported in the routed system package for Inventor.
I can use the parameter function to calculate the mass of a cable (using the formula from NEMA-DTL-27500) and it will export it to the custom section of the iproperties for the harness (as text). Is there no way to link it to the actual cables for inclusion in the overall mass calculation. The cable is no different from any other part in that it has shape and mass. Using iproperties, i can assign mass to the connectors and backshells in my content center. These parts are not necessarily uniform in shape or mat'l. But if I cannot assign mass to the wires and cables then my efforts to use Inventor to calculate the COG are futile.
As for wire and cables having different densities, yes that is true. That is why the specs provide the information for figuring out the specific masses for estimating the mass of your harness.
