How to make zero values blank in repeat region, Creo 8
Hello, I have an assembly that uses various lengths of raw materials. To indicate this, we list the raw material and what length to cut it at. We currently have it set up so there is a special "CUT_LENGTH" parameter controlling this length for use with pre-defined flexibility and easy identification of the driving parameters. We want to add this parameter to the CONFIG.PRO file so we don't have to manually add this parameter in every time. When doing so, it defaults to a "0" when not being used (which is ok) but it shows this in the custom BOM, so we end up having to delete the parameter per each item. Instead of having to delete said parameter, we would like to have it controlled by a relation that basically says "If the cut length is equal to 0, replace the value in the BOM with a blank, but leave all other cells alone." I can get it to edit all of the cells where the "CUT_LENGTH" parameter is shown at once with no issue. But when I try to specify which ones to change/leave alone, Creo blanks out all of the information to the left side of the cell. I am not sure if I am missing something or this can't be done etc.? Any help would be greatly appreciated.
