[Ma...] Posted October 27, 2022 Share Posted October 27, 2022 This is newer ISO standard. Don't know exactly now, but i think that this is used for rectangle tolerance, where width is defined by plane perpendicular to base "V". It gives you direction of tolerance - perhaps they just want to report only one axis. If no one will have better answer, than on monday i'll lookup on docs at work.
