can you please make videos showing use of gd n t and som and various subjects in automobile design and manufacturing. thank you.
Hello Professor Cummins. Nice work. This helped alot. I"m going to go look at your other videos.
I am weak in reading sectional cut drawings please make basic understanding videos to learn it please help me......
It would be great if you please share a video about how to read GD&T control frames with the different symbols!
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.
Thanks! I really appreciate that!
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
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!
I appreciate you watching!
He sounds well hydrated
😂😂
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!
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!
Thanks a lot Gilbert! I do that because I've had so many teachers that throw information at me too fast. I finally realized that taking in information incrementally worked for me and it seems to work for my students as well.
You are a life saver mate. I have been looking for this comprehensive coverage of engineering design for years. Thanks !!!!
Thanks for watching!
Great General Overview of the Basics of Reading Engineering Shop (Technical) Drawings.
Excellent examples and great information.

Thanks Tom! Thanks for taking the time to watch and comment.
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!
This was excellent and helped me so much! THANK YOU!!!
As a jet engine technician at Pratt, I can appreciate your efforts. Well explained as your communication skills are well above par 👍🏻
Michele Palmieri thanks! I appreciate you watching!
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
Best of luck to you. Whatever happens, keep pushing forward and don’t give up. 👍
This video really gave me gud perception on engineering drawings tq...
You summed my entire subject in just a few videos and i understood better....Thanks. I subscribed please do keep making such videos. :)
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.
LOL! Thanks for watching. Good luck it sounds like you have a really great plan.
Good Luck Mate. Best Wishes To You Forever 💫
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!
Thanks for watching!
Excellent video. This was incredibly helpful for me. Thank you!
You're welcome! Thanks for watching!
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 ❤️
Please make more. Thank you for the videos.
Thanks. Very helpful as a refresher before a job interview.
Good luck!
First angle projection is used in Europe and the third angle projection is used in the US, you said the opposite
😂 And there I thought the Americans had something right for a change
Naa third angle projection
is UK, and first angle projection is US
@@melvintatah3703 Wrong! First angle is used in all the world except UK and USA how use third projection...
@@melvintatah3703 sorry, you have it mixed up. 3rd angle is the ANSI standard (North America) 1st angle is ISO standard (Europe) You can verify this by looking at page 603 of The Machinery's Handbook. The Professor WAS in error, however, as 1st angle projection shows the Top view UNDER the front view, and the Right Side view is shown on the LEFT of the front view. Hope this helps the confusion.
You are correct. Whoever are contradicting you are wrong.
thank you for this nice discussion , need more about engineering drawing
Thanks for watching!
Beautiful mac I have been amazed with your teaching .Thank you very much.
Thanks for watching!
This was great! I'm making the transition from fashion design to industrial design. Thank you.
Fashion? That's really interesting. What brought about that change?
@@infinitymfg5397 Thank you for your prompt response! Well, I took mechanical drawing when I was in 7th. grade. It had a loooong lasting effect throughout my fashion career. I also have a product I'm designing that I want to bring to market. Other than that. I'm a Closet Engineer. By the way, how do I indicate/measure/determine curves?
Thanks for sharing useful information 👍👍
beautiful, made my day
Awesome stuff man,thanks a ton.
Thanks for watching!!
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.
Thanks Brother, its really helped me to know better
This was very helpful sir, thanks for sharing!!!!
Thanks for watching!
Appreciate your effort and simplicity that you have brought to the topic but get those angles right! First angle is used in Europe typically:)
Its pretty scary to do my mechanical drawings in the real world compared to my university days. Your video helps a lot, cheers!
That's awesome to hear! Thanks for watching!
Very informative👏👏👏
This may get me the engineering job tomorrow it has definitely expanded on my knowledge. Cheers mate
Good luck! Thanks for watching!
Did you get the job?? :)
@@silviafamania3606 I did thank you for asking
@@armed_but_blind2768 thats awesome! Im glad for you. Im actually at the same position as you were. Im watching this video for a job interview too 🤣 wish me luck
Awesome Video 👍
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.
This was huge. Thank you!
Thanks for watching and support.
this video is very useful thank you sir
thank so much sir, this really came handy. it is in this video that I have also understood the projections. Grateful
Thanks for your support!
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!
Wow! Thanks and good luck on the interview!
Awesome. Thank you
Correction: first angle is mostly used in Europe and Asia (maybe UK too, don't know)
Third angle is most commonly used in USA.
Super helpful thanks man! God bless🙏🙏
Thanks for watching!
Excellent Intro.
Brilliant thank you :)
Thanks for watching!
Ive never understood a blue print in my life until i watched this video
Thanks for watching!
Very HELPFUL .....Thanks!
Thanks for watching
No problem what does Range of tolerance mean?
You are the best. Thanks a lot.
Thanks for watching
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!
Hi Harold, thanks for watching! I am putting together some full courses in these topics. Currently I am trying to gauge interest. If you would like, you can go to my website and subscribe and I will keep you informed.

Sir, thank you so much for the well-explained tutorial. I think first-angle projection is mostly used in Europe countries.
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
Thank you
Great Thanks!
very nice zoom in drawing sheet
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?
Thank you for the education ! So appreciated
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.
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.
very good explanation
Thanks!
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!
EXACTLY thanks for pointing that out...I thought I was wrong all these years...lol
same here.. 3rd angle for US and 1st angle for europe. but still awesome video.
Thanku sir
Great video
Thanks Bogdan!
Please issue more videos on gd&t particular .... for automobile industry
Hi Harsh! New videos are coming soon! In the mean time, go to our site and sign up so that I can keep you posted. www.theengineersreference.com/videos-2/engineering-drawings/
great video
Thanks! I appreciated you watching!
Great vid.
song of the background? anybody?
amazing videos! And who is playing in the backgroud?
Thanks for watching! Its just a canned music from my editing software.
what are you using for edit?
Screen cast-o-matic. Its not the most sophisticated, but is very easy to learn.
thanks
Thanks for the video,can you recommend a book that might help
google gave different information about 1st and 3rd angle projection, 1st angle is used in Europe and asia not 3rd
thank you very much sir
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
nice
By he way, ho does one determine curves of a design, R16.00, R12.5 ect?
do I read blueprint of the screw?
its so good but i guess first angle is used in europe and asia and third angle is uded in us and canada
Don't forget this is also to quality control / inspection. ;)
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
LOL! This is awesome!
Sir please Suggest me the subject
Which will be related to my work experience.
I am from India
I can't suggest a subject for you, that is a personal decision that you will have to make based on your own goals, strengths and interest. Maybe speak to your graduate school advisor for some direction.
Freeze bro
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.
Thanks for letting me know. I must have misspoken. I will have to be more careful in my narrations.
Thanks for subscribing!
it might be worth adding an overlay message to correct that. awesome vid otherwise though!! :)
Zachary Logan yeah I just took a long course on this for work , it’s reversed.. 1st Angle is Europe , 3rd is US
that's the thing i was thinking
I agree. I work for a French company and we use first angle protection exclusively since it's European standard. My machinist instructor became enraged after seeing this mistake.
what is the name of the music I love it
What does the scale denoted? e.g. 1:2
When a drawing uses 2 types of units, such as fractions & decimal inches, dual dimensions should be used
Hello, i need gearbox shaft engineering drawing with dimensions, can tell from where can I get one please
👍
Sir, I want to learn cmm machine operation and programming.. can u help me.. I m fresher .. plz guide me.
I can look into it. Actual programming is not as easy to do in a youtube video.
Please can u keep exercises
what is the difference between Drawing number & Part Number
I know this video is old and very helpful, but the US uses 3rd angle projection whilst Europe uses 1st angle projection.
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?
Nothing covering grain direction?
Sir, you sound exactly like Mr.Khan from Khan Academy
please do more video
The right side view in the first angle projection... The inner-circle should be a hidden line.
RED stickman is best stickman!
Sir, this is really helpful but if you remove background music it would be really nice. Thanks
3rd projection view is north America bro.
