OK so here is my complex problem: I am trying to get My parts custom property (RawQuantity) to automatically give me my Weldments Total Length in Feet. I have Found some work arounds to get weldment property "Total Length" to my part property. only problem is it is in inches and i need it in feet. If i change my units in the drawing it changes as expected, but I need my drawing units at inches so as to display my cut list bodies lengths in inches. We work primarily with weldments, and use custom weldment profiles. Custom weldment profiles have allowed us to auto fill our cut list to show individual body lengths. Old way was using equations to add up lengths x qty and dividing by 12 to get feet. Problem is that even with table linking to custom part property, equations will not update the part property. I am told i word things confusing at times hope this picture explains it better. picture is an extended BOM to show weldment bodies. help would be appreciated.
