The dialog boxes for ANSI and ISO weld symbols differ for symmetric welds.
In the ISO dialog box a symmetric option is available.
When ticked, the weld size value for the second weld is made invisible.
In the ANSI dialog box a symmetric option is not available.
So weld size value for the 1st and 2nd weld are both visible.
Is it correct that the ISO dialog box makes the 2nd weld size value invisible?
In Inventor ISO and ANSI symmetric weld symbols can show size values for the 1st and 2nd welds.
