All - Does anyone know how to swap a linestock file on-the-fly that a pipeline uses for automation purposes? Ideally I was hoping to use Pro/PROGRAM, but have not had any success. I don't want to use the Mod-pipe-Linestock method because my end user is not Proe literate. I'm trying to automate the creation of a piping assembly based on some key user inputs from a layout. Any help would be great.
