Sir, at around 23:58 you have it reversed. The U.S. and Canada (basically North America) uses the ANSI standard 3rd angle projection, Europe uses ISO standards 1st angle projection. In 1st angle projection the Top View is displayed beneath the front view, and the Right side view is displayed to the LEFT of the front view. Thank you for your interesting videos, they are explained very well from the ones I have viewed.

1st angle projection used through all parts of Europe and often called European projection. Third angle is the system used in North American

As a guy who does this for a living, I find it pretty useful to share your videos to someone, when they ask me to teach them about CAD drawings and stuff, you explain this stuff a lot better than I can, great job man, keep up the good work.

I loved how you explained 1st and 3rd projection. Your explanation was as clear as mud.

I started a job as CMM technician in aluminum manufacturing company and was looking for a video that explains the blueprints that i am using every day. Great video thank you

I'm trying to fix my life getting into welding as I'm really far behind career wise compared to everyone else my age and these videos may be the difference between me getting a job in welding and just repeating history. Thank you so much

This was so helpful! I haven't looked in-depth at blueprints/ engineering drawings in about 15 years and have an interview tomorrow needing that skill. This reinforced what I already knew, and added the first- and third-angle info. Thank you!

Glad I found your channel. I just started to retrain myself to be a Machinist at 54 years old. I don't know how realistic that is but I'm determined to learn. because I inherited my dads Late and Vertical mill and I would like to work out of my own shop again. This is a good video even if it made my brain hurt.

First angle projection is used in Europe and the third angle projection is used in the US, you said the opposite

Great video... Not to critique the expert, but from what I've been reading, first angle is actually more common in Europe.. Third in the US...many thanks for the well laid out video!

You are a life saver mate. I have been looking for this comprehensive coverage of engineering design for years. Thanks !!!!

I have an online CAD course and there was no information about reading the drawings that we were supposed to model. Really great video, thank you!

He sounds well hydrated

Thank you for the great video. You really broke things down in an understandable way. I like how you gradually made the drawings more intricate, building on each point you made before. I'll be watching your whole series!

As a jet engine technician at Pratt, I can appreciate your efforts. Well explained as your communication skills are well above par 👍🏻

Great General Overview of the Basics of Reading Engineering Shop (Technical) Drawings. Excellent examples and great information. T J (Tom) Vanderloop, Author, Manufacturing Consultant & Technical-Educator

Really amazing tutorial . Thanks and my prayers is with you.I got so much from this video

Really enjoyable to watch! Explained everything in ways that was easy to understand and with just the right amount of information that doesn't make my brain feel overloaded. And by far the best when it comes to easy listening. The tone and pace is great while keeping my attention and at the same time feels relaxing. Look forward to watching and learning more!

This may get me the engineering job tomorrow it has definitely expanded on my knowledge. Cheers mate

This presentation was very helpful and succinct. The only place where you lost me was in the explanation of First Angle versus Third Angle Projection. While I understand how the drawing wants me to turn the part given either type of projection, I had a hard time following the explanation of why each type of projection was labeled as it was. I also had a hard time imagining how being at different places around the house would change the direction I'd have to rotate the house to see its orthogonal projections.

Appreciate your effort and simplicity that you have brought to the topic but get those angles right! First angle is used in Europe typically:)

This was great! I'm making the transition from fashion design to industrial design. Thank you.

Excellent tutorial. I have a job interview and their requirement is being able to read CAD drawings. This was a great refresher from the few years of drafting classes I took in H.S. Well done!

So well explained Sir. Really helpful to understand an engineering drawing as a beginner.The language that you explained in is just amazing and the background music made the whole experience enjoyable. Would love to see more of such videos in future ❤️

Love this video - very helpful! Must point out that you got the countries switched around that use 1st angle and 3rd angle projection. The USA uses 3rd angle projection, and Europe and India use 1st angle projection.

Its pretty scary to do my mechanical drawings in the real world compared to my university days. Your video helps a lot, cheers!

Good description, but you have an error. At around 11:00 minutes you refer to 1st Angle as commonly used in the US and 3rd angle in Europe. The reverse is true. First Angle is sometimes referred to as European projection while third angle is commonly used throughout North America.

Excellent video. This was incredibly helpful for me. Thank you!

thank so much sir, this really came handy. it is in this video that I have also understood the projections. Grateful

You summed my entire subject in just a few videos and i understood better....Thanks. I subscribed please do keep making such videos. :)

Thanks for sharing useful information 👍👍

Correction: first angle is mostly used in Europe and Asia (maybe UK too, don't know) Third angle is most commonly used in USA.

this video is very useful thank you sir

thank you for this nice discussion , need more about engineering drawing

This video really gave me gud perception on engineering drawings tq...

GOOD noon, Prof Cummins, all the way from here, Manila, Philippines! Kindly correct what I believe an apparent confusion you pointed out: FIRST ANGLE Projection is Europe's, THIRD Angle is US'. Thank you very much!

Beautiful mac I have been amazed with your teaching .Thank you very much.

Sir, thank you so much for the well-explained tutorial. I think first-angle projection is mostly used in Europe countries.

Awesome. Thank you

Thanks. Very helpful as a refresher before a job interview.

Super helpful thanks man! God bless🙏🙏

Ive never understood a blue print in my life until i watched this video

Please make more. Thank you for the videos.

I assume there is a mistake in your explanation. The 1st angle projection view is used in Asia and European countries. You said opposite oif this. And also the given drawing is 3rd angle projection,but you will tell it as 1st angle projection. Please verify them. In case I am wrong please explain me . Anyhow your videos are good. I am a subscriber of your channel. Thank you.

Sir you have explained about the engineering drawings pretty well, but you haven't mentioned about Datum line or Datum surface. Can you please share some knowledge about it

This was excellent and helped me so much! THANK YOU!!!

In addition to first & third angle projection mistake, please, also note the mistake in Detail view section (around 16:50) - the scale is totally wrong. How it is possible to use such scale?! Please, refer to the final drawing (the flange plate around 21:20) and check the correct scale for detail views.This video should not be used by beginners at all. It plants a very, very wrong information and later it will confuse you. I already had a discussion with a person, whose main argument was "But, I saw it on RU-vid channel - so it is true! Period!"

Hello professor, I'm a machinist apprentice learning how to read technical drawings/ blue prints. Unfortunately this is kind of an accelerated class and they're only giving us 5 to 6 days to understand the material. It's been 2 days into the class at work and I can't understand how to get the measurements of the workpiece and understanding how all the different lines connect and lead to the numbers I'm supposed to add or subtract.

This was huge. Thank you!

Awesome Video 👍

google gave different information about 1st and 3rd angle projection, 1st angle is used in Europe and asia not 3rd

Thanks Brother, its really helped me to know better

Awesome stuff man,thanks a ton.

Great job Professor I enjoy watching your videos, especially the GD&T series, and Blueprint reading. What I will ask of you is can you go over in more detail MMC, and LLC as this still sometimes confuses me. I wil howeverl subscribe to your face book page as well. Peace n Happiness!

very good explanation

Very informative👏👏👏

I know this video is old and very helpful, but the US uses 3rd angle projection whilst Europe uses 1st angle projection.

Very HELPFUL .....Thanks!

This was very helpful sir, thanks for sharing!!!!

You are the best. Thanks a lot.

Thank you so much I really need this can you please show me a drawing for a transmission and the different components in it and how to understand it how to identify each component please

beautiful, made my day

Wrong information told by the instructor. Correct one is -- 1ST ANGLE USED IN EUROPE AND ASIA, 3RD ANGLE USED IN NORTH AMERICA.

its so good but i guess first angle is used in europe and asia and third angle is uded in us and canada

Excellent Intro.

The right side view in the first angle projection... The inner-circle should be a hidden line.

Thanks for the video,can you recommend a book that might help

Please issue more videos on gd&t particular .... for automobile industry

Great Thanks!

Thank you for the education ! So appreciated

Thank you

great video

what is the difference between Drawing number & Part Number

By he way, ho does one determine curves of a design, R16.00, R12.5 ect?

Is it true that the top of the part in horizontal orientation while viewed in first angle projection or any layout is opposite of the title block? If the TB is located on the bottom right corner then the workpiece top would be on its left side yes?

Brilliant thank you :)

thanks

Greeting of the day! Sir, I am a graduate Mechanical Engineer working in Quality Department in an Autopart Mfg company. Which subject should I choose for Master. Next Year I am planning to go Germany. Please Suggest

Sir, this is really helpful but if you remove background music it would be really nice. Thanks

very nice zoom in drawing sheet

Yalow pointer is not visible i think it will more visible if changed to red or blue thank for the video

Hello, i need gearbox shaft engineering drawing with dimensions, can tell from where can I get one please

you have a issue at first an third angle proyection 3 is used at US 1 angle is used at Europe or your image are rong

When a drawing uses 2 types of units, such as fractions & decimal inches, dual dimensions should be used

do I read blueprint of the screw?

amazing videos! And who is playing in the backgroud?

Nothing covering grain direction?

3rd projection view is north America bro.

Sir, you sound exactly like Mr.Khan from Khan Academy

I have a background in engineering, but not decades of experience, so I have a question for engineers, machinists, and technicians with decades of experience in design and manufacturing. From college, it was apparent that metric units were superior to English units; it simplifies things and helps prevent mistakes (reminds of the costly mistake between NASA and Lockheed). All of my fellow engineering students concluded we would be better off if everything was metric. At the same time, as a school machinist told us, the prevention or slow move to all metric is partly due to the cost associated with making the transition. Does that resonate with those more experienced in manufacturing?

What does the scale denoted? e.g. 1:2

Please can u keep exercises

Don't forget this is also to quality control / inspection. ;)

Sir, I want to learn cmm machine operation and programming.. can u help me.. I m fresher .. plz guide me.

Thanku sir

thank you very much sir

what is the name of the music I love it

right hand rule and x is up and down? say what?

Great vid. song of the background? anybody?
