- Watch the bonus video on model-based definiton and statistical tolerance analysis here! nebula.tv/videos/the-efficien...
Engineering drawings are key tools that engineers use to communicate, but deciphering them isn't always straightforward. In this video we cover the fundamentals, including the different types of views, first and third angle projection methods, dimensioning, tolerancing, best practices when creating drawings, and GD&T (geometric dimensioning and tolerancing).
---
Corrections:
04:00 - Several of the views are drawn incorrectly. The right and rear views should be flipped horizontally and the bottom view should be flipped vertically.

Hello. The knowledge from your youtube channel is very useful. I think it needs to be spread to more people. I want to translate your video into Vietnamese and post it on my youtube channel. I will quote the source at your channel
i'm confused when you display the 6 total views at 3:59. shouldn't the right view have the sloping face on its left side? and the notches visible in the top/bottom and rear/front views should be mirrored to each other? when you deconstruct the 6 views from the cube shape, some of the views are flipped the wrong way, so we're seeing the image from behind, rather than how the camera saw it from the side it was taken. right?
Hello there! I am a mechanical engineer, i work as a project engineer in HVAC industry. I have been watching your videos since you started making them. I am very frustrated on the fact that our teachers wasted so much of our time, energy and resources. I thank you for all your efforts, your videos are unparalleled, simple and detailed. More power to you. Keep up the good work!
Machinists: "don't show the engineers how to use GD&T!"
oh, so YOU'RE the reason why none of my parts fit.
@@theastuteangler I’m not a mechanic but always try to make an effort to make designs serviceable.
@@theastuteangler It never works though...
I really love this field of mechanical engineering, and I hope work as a mechanical engineer (Hvac designer), can you help me please to keep through this road? 🥺
As a technical drawing and CAD teacher I really admire your work. It is top notch job - absolutely profesional, detailed and what is the most important thing - easy to understand. I'm recomending your channel to all my students.
There's so much high quality content on UA-cam for Math, Physics, Biology and Computer Science
About damn time engineering got some love. Thank you for your amazing work!
do you have specific channels in mind? I'd love some recommendations if you have any, thanks :)
@@aembal second that
@@aembal crash course . It’s the OG of UA-cam edutainment
@@aembal If you're asking for engineering related channels, there's Real Engineering, Stuff Made Here, BPS Space, Tech Ingredients, EEVBlog, ElectroBoom and a lot more I can't remember.
When it comes to Math, 3Blue1Brown and Numberphile are my go to, 3Blue1Brown had an event called "summer of math exposition" and the videos that came out of it are all amazing. For the other sciences, there are honestly so many high quality channels that I can't remember any off the top of my head.
True that. there is a lot of good quality content online. The good thing about engineering is that the principles are the same across the world even though local design codes can be different..
I am blown away by the quality to animation, thank you for putting so much hard work on this video.
I found myself not paying attention to the material and wondering how the heck those animations were done.
@@mikemazzantini6397 I was wondering the same thing.
Every mechanical undergrad will thank you. Great work.
I am studying mechanical engineering and I really love and appreciate your work (and art)! I often rewatch your videos to recall and internalize. Looking forward to further content! :)
fun fact: Russia has the greatest quantity of engineer graduates each year
@@yepi3345 ?
@@yepi3345 who cares
@@yepi3345 I'll also bet the US is far behind much of the world because of affirmative action programs. Even our high schools are failing because of teachers unions. This will eventually ruin our country.
At this point every undergrad engineering course is making use of your videos as resources we have to study, and I am all for it. Hope you don’t mind unis using your material without your permission cause it’s so much beyond anything else that exists to explain these concepts in quality and clarity.
Thank you
Speaking as an MSc in Process Engineering, I have no idea why these stuff was never explained to us so well like it was here. I've spent 4.5 years in university to then find out I don't know anything and actually learn some fundamental engineering concepts from this channel. Thank you!
The older we become as engineers, the more we realize just how little we know...and just how INADEQUATE our learning in university was! BSME here.
Is this not taught in university I learnt it at my high school at 14 I thought this was common knowledge.
the greatest teacher is ALLAH, he guides us from the secrets of the universe to simple actions, which no school or university can teach you and our emotional perception is a miracle given by ALLAH
This 20 minute video just taught me more than an entire semester of my engineering graphics class!
Definitely
absolutely 20 mins in 5 years in high school!
This video is gold standard of explaining Engineering drawing
I am not an engineer or doing anything related to engineering drawing, I'm just a curious soul!... and i can tell that this is high quality content because you explained everything so eloquently that i even understood and followed along easily!... great stuff... I'm really sure people doing these things appreciate your content a lot!... big ups to you!
As an electrical engineer, I highly appreciate the high quality of your videos on mechanical engineering subjects, giving great insight to a person starting to learn about this.
This is my favorite part of enginering... Drawings. You can take earphones, play some bangers in it, "shut off" your brain and just draw. Ofcourse, its not a braindead activity, but at least for me, it is so relaxing and fun. Great video ;)
I'm now 77, and all my life I've been involved with engineering, drawings, and drafting. I ran a large drafting department for years. My High School Drafting Teacher told me I'd never make it working in engineering or let alone as a draftsman. My first job a draftsman! He told me that after I brought him a Drawing I made when I was ten years old, it looked exactly like these drawings. It was a detailed engineering drawing of a Spark Plug, an Aircraft Bracket, Moral here....If you have any fascination or feel like you'd want to draw like this..GO FOR IT..
As a just recent graduate in Mech i found the videos you make as boon for those who wish to summarize, revise and also have intuitive fundamental knowledge of the concepts that they didnt had before!
I will strongly recommend that you should do a complete series of videos on engineering drawings. Topics like GD&T, tolerances, fits, etc. need a thorough explanation.
This is ESSENTIAL for draftsmen and engineers.
My college instructor told his classes: "Everyone starts out with an A. If I have to ask a question regarding your drawing, that's a B. Two questions is a C. Three questions is a D. Four questions is an F."
Dr. Crist
I agree
As a design engineer I can tell you that this is one of the best videos that I have ever seen explaining an engineering drawing!
Just a quick note, as per ASME Y14.5 the symbol in 18:50 is called “Position” no “True position,” true position is the theoretical exact position aka the perfect position in the CAD, and the symbol is referring to the Geometric Characteristic of Position. This is a very common mistake in the engineering world
Just looking at that GD&T tol callout and the C datum seems redundant too. also the callout of 8 dia being +/- 0.2 when its already called in the callout on 0.2
As a mechanical engineering student I've seen a lot of videos, books, lectures alongside my main courses in college, but your videos has always been the best and most informative. Thank you for teaching and inspiring!
This comment section is full of smart people, working as engineer's, draftsman, and such, I personally, dont have a job, but want to become an aeronotical engineer someday, i really like how these videos explain it simply, and in great detail.
It's refreshing for us engineers to witness the wonderful work you do on your videos. Thanks much, for providing us valuable contents.
I am so joyful to see you uploading content again! Thank you for your time and sharing your knowledge. Please keep it coming!
Can't appreciate enough how elegantly the topic is explained. It is so soothing to watch the video. The animations are just perfect. Although the topic is too vast to be covered in a 22 min video, but still the basics are explained beautifully. Take a bow man....
im an mechnical engineer for a bus company in australia, this is the right way of interpreting the engineering drawings, we used third projections a lot in australia but you chosen the left view, i chose the right view as must display more solid lines instead of hidden lines, nice work!
The Return of the King
As a manufacturing engineer, this video is so helpful. School doesn't teach you how to understand GD&t and engineering drawing skills which are essential to most mechanical and engineering jobs and usually you have to do training.
So true, right now I am lucky to be receiving training as a mechanical engineer.
This is the video I have always needed!!! As a Technology and Engineering teacher I appreciate you making this video. The explanations and visuals are awesome and are really going to help my students! Thanks!
I am an aspiring engineer who has always struggled with maintaining a college education, both financially and academically. I found your videos on Nebula and wanted to show you support here as well. Your lessons are clear, concise, and easy for me to follow. Thank you for making these.
I'm a person like you, I've seen something in the eyes of future engineers that they study engineering in any field for financial gain, and I don't think it's fair, after all, our profession is to fill the world with brilliance and innovation, isn't it
I am an engineering student attending first grade of a higher techincal college in austria, and I loved the video. It was especially interesting to see the difference in the standards, and this was just so compact and informational.
Hi there. I'm an engineering student (shipbuilding & ocean engineering). I find that your videos are really good for learning and understanding. It's been really helpful. The animation and visualization on your videos are also amazing! I wish you all the best for life and I thank you for your contents.
What field of shipbuilding do you study
Clear and concise explanations with clean illustrations. Fantastic job. Thank you.
16:16 Tolerancing Best Practices
18:18 Geometric Dimensioning & Tolerancing
fun fact: Russia has the greatest quantity of engineer graduates each year
I wish I had these videos back in 2007 when I started the mechanical engineering course... a great resource for engineers for grasping the fundamentals.
I really appreciate your content. I'm a recent mechanical engineering graduate and you break down challenging concepts very well
Hi there , I went through college for Tool & Die Design and went directly into the military gas turbine engine field where I was for 16 years . After which I worked for various aircraft and aerospace companies totaling 40 years in the industry . Blue print reading is fun and interesting and GD&T also . I still have my drawing board . I use it for a large computer table . Good luck to all in the future and take care .
Electrical engineer here.
Until recently, I spent most of my time at work electrically testing components against their wiring diagrams, which means looking up a ton of mechanical drawings in the process of trying to find electrical information.
It's wild to think of how much detail I missed or glossed over, day in and day out. Thanks for explaining!
another great video from your channel. i have been on this channel since you had around 50-60k subscriber and it feels nice that your channel are growing and getting deserving appreciation.
You are the gold standard of educational UA-cam videos.
I am by no means an engineer, but rather an artist. This really helped me understand how to draw believable technical drawings and blueprints for sci-fi projects
Damn man, you explained in 22 min the exact same things my Uni drawing lessons explaned in 3 months. AWESOME!
Thank you for making such high quality content! Love the seamless animation
Electrical engineer here. Brilliant animation, presentation, and pacing. Using this to teach other engineers.
These videos are captivating in every regard. I am amazed how educational videos can be this good. Really and honestly every video on this channel is above top tier.
giving concept in such lucid way is simply incredible, please cover topics of fluid dynamics and IC engines
Wow, your illustrations are fascinating. I wish I had access to that kind of content back when I was graduating chemical engineering. I do share it with the freshmen so they can have a better time understanding the concepts.
This is a great video for beginners. Thank you for providing such a high quality on UA-cam on engineering drawings.
Dude.... It's absolutely frustrating that my college didn't do as good of a job at teaching me these applicable that these videos do. I've heard about most of this stuff and used it on my own but really felt like there were parts I didn't understand. These clear up a lot in a way I fully understand and I really really appreciate it. Thank you for bringing mechanical engineering into the 21st century
Your videos are extremely helpful and incredibly well animated, please keep making more and I hope you find more success on youtube and become a much bigger channel.
Even though I am an optical/electronics engineer, I enjoy your videos and find a lot of it useful. This drawing video was awesome. I learned drafting in middle school in 1977 and now use Solidworks a lot in my work.
THE BEST SUMMARY I HAVE EVER WATCHED, THANK YOU.❤
Outstanding. Forwarding to my former solidworks drawing and gd&t teacher. Glad to be a patreon.
Thank you for making such high quality content! Love the seamless animation. Every mechanical undergrad will thank you. Great work..
👍🏻 The compact and absolut clear content of information including the art of presentation of this tutorial undoubtedly deserves a kind of "Oscar for teachers"! 🏆
This is fantastic! The animated version has been incredibly helpful in visualizing the concept. Thank you very much for your hard work! Recently, I joined a water consulting company where I needed to analyze and understand drawings. I appreciate your efforts and keep up the good work!
Super helpful video! I'm doing a lot of drawings at my new job and needed something like this to demystify everything.
This video cover up all of my 3 years engineering design & drawing flawlessly
I would love to see you do a video on Gd&t. You explain everything so well. Keep up the good work
You are making one of the best informational videos on yt hands down. The explanation and visuals are just astonishing. Keep up the good work, hope your channel grows and thank you.
Do you have any idea about the used software in this video ?
Soy un estudiante de ingenieria Mecanica y de verdad te agradezco mucho el trabajo que haces.
Wonderful illustrations of concepts that are often overlooked in the typical engineering degree program. Thank you for sharing to the world!
I think that the right view of the example piece at 4:20 is inverted following a vertical axis
What an absolutley fantastic video! The amazing animation, to the well spoken tone you have through the video makes this rather challenging topic easy to understand! Than you so much!
Do you have any idea about the used software in this video ?
@@hannibalbarca8411 Unfortunantley i don't, sorry!
Well done for this wonderful and info packed video, really wouldn't want it to stop.
Awesome. Looking forward to your future GD&T video!
this is GREAT content. So happy I found your channel
Very useful information and your way of explanation is really commendable. Would like to watch more of your videos on GD&T content very soon.
This is a MASTERCLASS! This is now my goto reference video for my students.
Excellent graphics, very easy to understand, I appreciate the hours you spent making this!
Thanks for this amazing video, I started yesterday a course called Fundamentals of mechanical engineering where we will use Solidworks, so this video literally came at the best time
Millwright apprentice here, your video explained more than three of my drafting classes so far. Thank you
You're one of the best things that ever happened to youtube. Thanks for another superb video!
I had to comment mid-video, this is THE best video on Engineering Drawings on YT. Thank you for your efforts and explaining it so easily. SUBSCRIBED
thank you so much for such a great and summarised video i have been searching for such a video with all the basics directly!!!
One the Greatest Video about Engineering Drawing, For me I have learned as much i have learned in my initial 3 Months of Engineering Drawing Subject in my Diploma Engineering Course.
Loved it, Waiting for more if this ...!!! ❤
Should have saved a fortune doing engineering here than spending ridiculous money for college. God bless you. Our nerd engineer's community needs such youtubers.
Na koniec mój "ulubiony" przedmiot. Czekanie do sesji nic nie da, jeden rysunek zajmuje jedną noc, a w semestrze było ich chyba 12. Literki duże mają mieć 7mm, małe 5mm, pomocnicze duże 5mm, małe 3,5mm, odmierz pół milimetra, kupiłem sobie szablony, dzisiaj już tego nie kupisz. Agnieszka nie ma złych uczniów, są źli nauczyciele. Ciebie wspominam dobrze, bardzo mnie motywujesz, no chcę się przed Tobą popisać.
Thank you for creating these videos I really appreciate what you are doing! Much love and wish you the best!
Very much looking for GD&T, thank you~
Even as a mechanical engineer who is approaching the end of my career this was an excellent refresher video about engineering drawings
You have no idea how useful this video is and the amount of time it could've saved for me
Thanks for the clear visualizations to whoever made them!!!
This video is just phenomenal, Respect!
Fantastic video. Thank you sir and keep up the good work. Looking forward to the GD&T video.
I'm so happy to see you again ❤️
I've been looking forward to your videos🥰
This video made me realise that simply because someone is smart, doesn't mean they are a good teacher. I am incredibly thankful this channel exists to freely step in when the universtiy I am paying to go to is failing me.
Excellent info on bolt thread and pitch at minute 12.
Thank you far making this video. You're helping the world learn a better way
Absolutely helped me a lot. Keep up the good work. Thanks
This single video cover whole my first semester good job dude
I just worked in METAL CNC IN SAIGON- it’s so useful . Thank you
wonderfully explained, subscribed!!!
Excellent videos. I wish your channel had been around when I was in school!
One of the videos that engineering students should definitely watch!
Fantastic educational video. As a future mechanical engineering undergrad, thank you!
As Junior Mechanic of Heavy Equipment. Structure and Assemby drawing really help alot for assembly/disasembly, even Searching problem for complex thing like Electrical and hydraulic system. Sometimes read the schema is cost little times, than grind your gear inside your brain everytimes.
PLEASE NEVER STOP. Youre saving mech engineers like me!
Love these videos. I'm a software engineer, but I actually apply some of these practices to my designs
I'm currently studying Computer Engineering and these drawings always amaze me. My father works as a mechanical engineer in the mining industry and I have seen some of the drawings on his computer. They are very complex for me to understand. Perhaps now I would have a better understanding haha.
You make the most excellent and informative videos. Excellent job and thank you!!
Very good video explaining the most important meanings of symbols on technical drawings. Well done!
