I'm pretty sure at 57:35 the centre line does not on it's own suggest a cylindrical shape - only that it is symmetrical about the centre line. You'd need a second view to show the cylindrical nature, just like how the 3rd angle projection symbol needs both the circles and trapezium.
The drawing at 7:50 seems to break a lot of rules- complete circles should give diameter (not radius), leaders seem to touch parts, numbers through the dimension line (instead of above it). Also, M6 does not give pitch... Also, at 1:01:40, pitch is given but not explained.
Excuse me, I`ve seen a confusing technical specification recenly. Could you help me understand what theese things mean «B edges fitting is allowed during following assy» and «Other TS comply with 12 100TU» The confusing part is «B edges» and «12 100TU»
most fun I've had in years, amazing video!
Thank you sir.you reminds me when I was w teacher in the high school in Ghana 1992.thank e

Thanks for this, really helpful for my upcoming engineering exam
Very good video. Thanks for this!

Great video, will show to some secondary engineering students.
Glad you found it useful. 🤝
Indeed he is very good
Nice lecture, I enjoyed it.

Thanks, please can you suggest a text book for GD&T BS8888 UK standards, latest edition
I would just like to ask a question please. Does BS8888 allow for both first and third angle projection views?
Hi, yes BS8888 talks about both the methods of projections. But more universal these days is the third angle system.
