Thank you so much Mam. Your videos are very much useful to learn GD&T basic concpets and put it practice in our regular work. Could you please share your videos on GD&T Straightness, Circularity & Cylindricity as I have seen GDT Flatness video only in Form tolerances category. Appreciate your great work and keep up the good work!

Hello Margaret, thank you for lucid explanation. Really appreciate your work. I have a doubt. Flatness tolerance zone is two parallel planes seperated by flatness tolerance value and its location is not fixed. But where does the tol zone exactly lie? (since we dont have datum for it) In other words, in the table example, where does the top plane of tolerance zone lie? Lower plane will be at distance of tolerance value, but confused as where does the top plane lie. Hope you've understood what I am trying to ask.
