I have some questions about this print, and I tried to make some changes as shown below. The reasons for making these changes are:
The common datum(A-B) is constructed after the individual feature is designated as the datum feature.
The existing DRF refers to the datum feature itself, normally...
Please ref to the attached fig and video, is this the right way to measure the profile as shown on the video?
Please advise the correct way to measure the profile if the video is wrong
Thanks for your help in advance...
The figure below is a straightness callout on a shaft with a MMC modifier, but here I'm not talking about straightness, but circularity and cylindricity.
May I ask What are the maximum errors of circularity and cylindricity respectively.
Thanks for your help in advance

2018 standard tell us how to measure the local dimension on a localized area that do not contain opposed point, my question is if no opposed points on both sides as shown below, then how to measure this local dimension?
Thanks

Please ref to the section view below:
Its an ISO spec, I havn't seen dual flatness callouts before, what is the meaning of each callout?

If the planar surface is a sealing surface and has been designated as a primary datum feature, in order to prevent the distortion direction, we may add a refining note underneath the FCF, may I ask which note is reasonable and will meet the functional requirement? Please ref to the figure below...
Hi All
Please ref to Fig. 12-2 of Y14.5-2018 as shown below
I have a question at "Means this", how can a 0.2 tolerance floating within a 0.03 tolerance zone? Please let me know if anything I missed here. Thanks for your help.

Please ref to the figure below, two questions need help:
1. Is it valid to have a Free-State symbol within the flatness FCF? Since the restraint note on the drawing will override the Free-State default condition, so I will say No, am I right?
2. What's the meaning of the 2nd segment flatness...
Hi all
I'm wondering if it is valid to apply the all around and between symbol at the same time on a profile tolerance callout,
or are there anything that I missed here? Please ref to the picture below.

Hello All
This figure is dealing with the implied datum sequence instead of the gage size, but I can't figure out how to get this MMB gage pin size 120 on the figure posted, I will say it would be 120.10 from the existing data, Please let me know if I am wrong. Thank you.

Please ref to ASME Y14.43-2011 page 71 Fig.B-5
There is a MMB datum feature modifier followed Secondary and Tertiary datum feature respectively on FCF callout, but why not shown on the gage FCF callout?
Thanks for all inputs in advance.

Please see Figure 7-12(c) of 2018 version as shown below.
My question is : the unit vector designation [1,0,0] followed by Translation modifier means the true geometric counterpart of datum feature C can be moved by 1 unit vector on X-axis as indicated by the arrow[highlight #FCE94F](Edit...
Its a simple part per ASME Y14.5, and I know its not allowed to label a center line as a datum feature, so I am confused on how to setup the part for inspection, what will you do? Its not a good print, any comments are welcome.

Hello All
Please advise which one is correct on the LMB calculation:
Y14.5-2018---LMB = LMC - Geo Tol
Genium-------LMB = LMC + Geo Tol
Please see the attached for details.

Hello All
A simple question---Can we add MMC modifier on a datum feature established by datum target points? If yes, what is the VC size and how to build the gage? Please see the attached for details. Thanks...
Hello All
Please ref to the snap shot below, this is from Y14.5-2018 Figure 11-35, I'm interested to know what will be the differences by removing the Dynamic Profile Modifier from the lower segment.
Thanks in advance
