I have various sheet-metal parts with loads of stud-welds iam trying to dimenshion all the stud-weld positions.

The problem i have is on the flat inside part of sheet-metal i can dimenshion the stud-wels centres no problem but the ones that are on the inside of flanges i can only select the inside or the outside of the stud i have overcome this bye drawing a construction line through the centres of the studs but this is very time consuming is there any other easy way to do it.
