Starting with Creo 8, you can create welds with intermittent spaces between the welds in Creo. A new Intermittency panel has been added for intermittent fillet and groove/butt welds. From here you can define pitch, number of welds, and weld spacing.
A new Intermittent tab has been added to the Weld Preferences dialog box. The report of the other side numbers for staggered welds has been improved. The WELD_LENGTH parameter has been added for all weld pieces. Click here to learn more
