I am trying to get the Bill of materials in my drawing to automatically input the length of a weldment, which can automatically update if the length is changed. When I do a weldment model I insert each part of the cutlist into a new part and then create a new assembly and insert each part by placing it onto the origin so that it lines up the axis'. I then create a drawing and insert the BOM. The BOM gives me the name, description and quantity but not a cut length. Can anyone help me.
