profile surface point indicators
hello,
i am wondering if anyone can help with a question i have regarding profile of a surface. is there a rule of thumb as to when point indicators should or should not be used. i can not find a definitive answer in the standard (y14.5m-1994).
check out our whitepaper library.
when you have a specifc zone you wish to control, or when the desired is not self-evidently clear. |
