Am trying to add a column to a custom BOM that is calculated based on an Assy custom property. As back ground, we have a custom BOM that is loaded onto a sheet in the assembly drawing that serves as a tooling build release document. It displays the part number, description and qty to be manufactured. This quantity though should be calculated as "quantity per assy" x "number of assemblies to build". Ihave a custom property in the assy model file which is "Assy Release Qty". When adding a new column to this BOM, when I go to enter an equation, under custom properties, the drop down shows properties from the part files, not from the assembly. Is there a way of accessing the assy custom properties?
