Anyone know how to check an external (due to old rule number 3) thread for pitch also so i can use it as a Datum ? Any simple step-by step direction would be awesome!!!
Checking the pitch diameter is not possible, but you have options.
You can check the pitch diameter outside of the program, use a key-in dimension and input the measured value into a generic circle.
You can also forgo the pitch, and just measure the major diameter using auto-circle/cylinder and utilizing the pitch option.
Also, you can combine the two to get a relatively accurate center from the auto-feature, combined with the pitch measurement obtained outside the program in a generic circle.
If it is RFS, I would skip measuring the pitch diameter altogether. If it is MMC, I would still advise against using the pitch diameter. The way threads mate leaves practically no usable positional shift to make use of anyways.
