Mr. Ricky Castles did a great summary of the ASME Y14.5-2009 (14-Character Symbols) for Size, Location, Orientation, and Form Controls (SLOF) as a GD&T hierarchy in 2021. The graphics are part of a universal language and the overall presentation was excellent. The functional modifiers are MMC-modifier, LMC-modifier & RFS-modifier. Datums are the key with the entire system. T J (Tom) Vanderloop, Author, Mechanical Designer, & Consultant; ATEA, AWS & SME-Life Memberships & Leadership
at 11:43...the problem is there are infinite amount of concentric circles separated by 0.01. You have not constrained the solution to just on of those. Is it that the outer and inner concentric circles have to be cntered around the perfect 30? So the measured surface would have to be between 30.5 and 29.5?
On the slide regarding angularity, the callout is 0.2, with no symbol for degrees. The translation says that the entire surface must lie between two parallel planes, 0.2 apart (again, with no degree symbol). In the audio, you mention that the two lines are 0.2 degrees apart. If they are indeed two parallel planes, the 0.2 should be a linear distance apart (inches/mm) not an angle; however, if the callout is indeed 0.2 degrees from the nominal angle, as clarified only in the audio, they are not parallel lines. So, what does the 0.2 represent, a linear distance between the parallel planes or an angular deviation from the nominal angle? Please keep in mind that the 0.2 degree tolerance zone would grow larger as the controlled surfaced extends from the vertex. On the following slide regarding perpendicularity, the 0.2 is defined in the audio as a unit reference. This is ambiguous as the linear units (in/mm) and angular units (degree/minutes/seconds) are all units.
according to this link, the drawings in this video are correct: the angularity controls angle and flatness, so it's specified using 2 parallel plane. www.gdandtbasics.com/angularity/
Hello This video is great to brush up things I want much more information regarding this will you please update some more video and Basically I am Mechanical engineer So kindly make patrician Because It's very difficult to find So make a group or segregate the things as per courses THANK YOU ..!!

after several hours of research this is the only video that explains how to read tolerances. And clearly. Thank you.
glad it could help!
Excellent. Thank u so much because already create this video. Best explanation, best knowledge... ✨👍

is there a way to obtain a copy of the slides shown during the webinar, they are very usefull
16:05 That's is not a reference dimension, that is a "basic" dimension the tolerance of which should be taken from the position feature control frame.
Where are the "lab exercises" which Ricky is referring to ?

This material coupled with example is really engaging and rewarding, nice job, thanks!

Thank you very much, this is a very precise and descriptive explanation!
This video is very useful for me so thank
Why cm? Very unusual. Metric drawings usually have dimensions and tolerances in mm.
best explanation of them all

Like ...nice information..

Thank you sir! I owe you my food
I like your slide show
