DML straightness is an exception to rule 1. Hence the part is not following perfect form at MMC(10.0).
In similar manner what will be the scenario for Resultant Condition , How to interpret the LMC size
Resultant Condition is simply the opposite of Virtual Condition. It is the boundary that takes into account the worse case size and position (including any bonus) that is opposite of the virtual condition. So for a feature being modified at MMC, the resultant condition is the LMC Size plus the position tolerance and the bonus allowed at LMC.

Thank you 👍
Isn't there a difference between ISO and ANSI? In ANSI you always check for enveloppe for a dimension and for iso you check only if its ask with a E in a circle? something like that?
Yes, I think this is the biggest difference between ISO and ASME Y14.5. Rule 1(Envelop principle) is default in ASME Y14.5. In the other hand, independent principle is default in ISO system.
Yes you are absolutely correct here! Alot of times on ISO prints we see the envelope principle being applied to the entire drawing via the title block since it is such a useful concept to employ.
