Thank you for the video. I keep going back to your video for any clarifying any confusion I had as I tried to learn GD&T myself. My favorites channel so far. Just sub your channel.
Hello Dean, You pointed to the tolerance.03 when you mentioned if the measurement is less… I guess you meant… less than .98. So in case, if the diameter is either UNDER or OVER, the part is out of specification. But some software still calculates True position for this feature when it’s at OVER size. Why is that?
So let me ask you this. For example the hole is cut at 1.02. Max big. That’s .04 bonus plus .03 given. Total .07. Now go back to the basic dimension. Can that 1.00” dimension measure up and left both 1.07”. Or only 1.035” up and 1.035” left. Or could it be nominal at 1.00” up and 1.07” left. All from edges like you have it drawn. I guess I’m asking if I was using a center finder cone on my height gage. And I’m gonna measure the 1.00” dimension both ways. Up and down. And then flip the part and do the other side, up and down. Can that part measure 1.07” both ways and still be good?
If the hole actual size is 1.02 then will get positive tolerance of .05 or it will be +/- .05 and if we can write is it like 1.02+/- .07, and allowable tolerance will be .95 to 1.09 ?
Hello..so for the same example if the modifier had been LMC, the allowable tolerance for 1.02 dia (LMC) would have been 0.03 and for 0.98 dia (MMC) it would have been 0.07? Thank you so much for this explanation, Sir. You made it incredibly easy for me to understand.😄
Hi, Bonus tolerance is applicable to features of size controlled with straightness, flatness, perpendicularity, parallelism, angularity and position. Maximum material boundary can be used with position & profile tolerance. This allows datum shift, which is different from bonus tolerance but has the “MMC” symbol with the datum reference so it looks similar. Thanks for watching & commenting!
You have done very big mistake by marking 1 inch size at two places which creating lot of confusion, which 1 inch you are talking about. You could have given 2inch size for position.
That's the best video about this topic I have ever seen in my life. Great job. Thank you!
I’m so glad you found my explanation helpful! Thankyou for the comment!
Never have I seen it explained so clear and simply put. Well done 👍🏾
Thanks so much! Great to hear.
Thank you for the video. The size tolerance chart really drove it home for me.
Great to hear! Thanks for the feedback.
Dean, outstanding video. You made the lightbulb go on regarding true position where many other authorities failed.
That’s so great to hear! Thank you for the kind comment & watching.

Awesome! Thanks so much. I’m happy you find my channel helpful.
Good job, Sir! Very clear. Very well explained!
Many thanks!
Very good video.I am from Argentina. Very clear this topic.Congratulations.
Thanks!
Great to hear! You’re welcome!
I agree with the rest of the comments, well explained, thank you!
Great to hear! Thanks so much!
very nice explanation, I finally get it. what if we were to also have an MMC on both the secondary and tertiary datums (B&C) in this case?
Love your tutorials.keep em coming
Thanks for the support! I have several videos in development, coming out soon.

Can you do a video on Additional tolerance in relation to a datum?
So let me ask you this. For example the hole is cut at 1.02. Max big. That’s .04 bonus plus .03 given. Total .07. Now go back to the basic dimension.

Perfect!!
Awesome. Thanks

Very helpful!
Great to hear! Thanks.
Appreciate your great work, thanks...
Thank you!
One question for curious knows... bonus tol is only applicable for position tol..or any symbol wil be getting it...pls explain..

@@RDeanOdell thank you
great stuff! much needed.
Thanks for watching!
Why does this work?
Thankyouu so much good sir. Definitely helped me understand more in my drawing dimensioning course🙇🏾♂️🙏
Awesome! Great to hear.
My books are GD&T Tolerancias Geométricas part 1 and part 2 and my UA-cam Chanel is GD&T y Metrología.
Wait how did you get .04 ?
You have done very big mistake by marking 1 inch size at two places which creating lot of confusion, which 1 inch you are talking about. You could have given 2inch size for position.
Thanks!
You’re welcome!
