Hey everyone, I'm seeing that lots of traffic for this video is coming from work training websites and university websites. Please let me know if your teacher sent you here! I can't believe I'm teaching the next generation of engineers!
Tomorrow I start my first job as a graduate engineer. Today I've spent the whole day panicking realising I don't know sh*t. Your video has really helped to calm my nerves and just remind me of some of the basics that I had forgotten. THANK YOU!
@@AshA-ul2vs Haha thanks for letting me know Ash! One comment I often get from experienced people who watch this video is "wow I didn't realize how much I knew!" Congrats on getting a job good luck!
This is bringing back flashbacks of my Mechanical Drawing days. (Where second years had T-Squares strapped to their backpacks in the 80’s). I learned Front View, Side View and Top View. Those sequences will be forever etched in my brain. (I guess the Top View here - which he omitted- would simply have been just a square box). But I guess the top view might be superfluous in this example, because it is so simple.
Work in the digitalization industry and 3D model and this is a terrific clear basis to understand blueprint projections and relations. Keep the good stuff!
It is entirely unclear to me how or when I learned mechanical drawing, but this is a *great* video and confirms that I've got a solid (!PUN!) understanding. Because I have no idea how I learned this, this video seems like a great way to teach folks!
I know what you mean, one time I took a ProEngineer class after self teaching for a few months, and I thought "wow I didn't realize how much I know how to do in ProE." Thanks for watching!
A great video, helps to put in perspective of various processess. When using a 3d CAD software, I never knew the problem associated with over-constrainig of dimensions, even though the sofware prompts to correct it. Now, it makes sense when thinking in terms of tolerances that can associate with these dimensions, and the ambiguity that a machinist may face, when reading the drawing. Thank you for a great content!
This is so awesome!! Thanks for making this! I have a design background in fashion and I'm currently an Assistant Technical Designer but I never realized how much my position relates to engineering (but for garments instead). It's really cool seeing how detailed views affect the end product. Watching this video was so helpful and it DEFINITELY helped me to see how my CADs can be improved and how overconstraining can lead to miscommunication.
I'm glad you like it! Thanks for letting me know. That's super cool that you work in apparel! I just started sewing a year or two ago and I think it's really fun. It should be more popular. It's cheaper, cleaner, and more practical than woodworking. I agree that making clothes is totally engineering. I think it would be a great way for kids to get their brains firing in a a designey and engineeringey mindset. What kind of garments do you work on?
@@TheNormalUniverse Yes I totally agree! Not only that, but after you've made your first garment/product, you feel incredibly self-sufficient. I was working on activewear (active yoga & workout tights, performance bottoms, sports bras, and tops) and some lifestyle (ready-to-wear/lounge) pieces.
SARAH FLY totally! I’ll really feel that way once I sew something good enough to wear in public. Hey want to be Instagram friends? I’m @LesGuichets. If you’re ever in the SF Bay Area say hi!
Love the video, the energy is awesome, I am an 11th grader who just found out the meaning of this, and I have been doing technical drawing for 5 years now
Thanks a lot! Keep doing awesome work. If you want to be an engineer full time I recommend to start building things, anything you find interesting. It's a great way to show that you're exceptional when you apply for internships and have stories to tell during the interview.
I Thank you for this, really am. I'm studying my first year of mechanical engineering, so glad I found this. I can say you made such a clear teaching, all the best for you!. Best regards
Thanks for letting me know. Congrats on starting mech E! My unsolicited advice is to start tinkering and making physical things as soon as possible. At some universities its easy to get all the way to senior year without getting your hands dirty. Thanks again!
Loved this video, the thing a lot of videos out there are missing is "know your lines", was trying to get refreshed on reading blueprints and this one helped me most. Well done, and keep up the good work. loved the quick quiz at the end.
Thanks for the nice comment! I always love putting quizzes at the end of my talks, because it's fun to learn but even more fun to apply the things you just learned.
Thanks for letting me know! Haha I’m glad you liked the quiz questions. Sorry I don’t know where to find more questions. I recommend to grab an object from around the house and make an engineering drawing of it, like I did with the GoPro in the middle of this vid. That will get the gears turning
Haha thanks, I was channeling my inner StructureFree, you should check them out. Really great channel about mechanical engineering physics topics like statics and material properties
Hey dude i love the way you teach is it possible to help me understanding the hidden lines thing in more detail? And also from two shapes I've to draw one axometric view and the other is top view I'll have exams in few days and i don't understand my prof.
Hi Besto sorry I don't fully understand your question right now. I think it would be best if you chat with your professor or classmates. Try making drawings for a household object together.
14:23 You are also missing two hidden lines to show the flats on both the top and bottom of the piece on the front view (leftmost view) and the tread depth. Great video!
hey there quick question, at 13:19 you give a guide of the different lines but i cant spot the phantom line that is at 10:48. Am i confusing myself as the phantom line has 2 dots but in the video its showing as 1
Hey Raz, thanks for asking. At 13:19 I accidentally labelled the "Phantom Line" as a "cutting plane line. You are right it has two dots separated by long dashes.
Actually that would be a good way to do it, but I was also trying to find an excuse to talk about the concept of using your judgement when deciding how to describe things in a drawing
Great video. In the "unclear drawing" example (@12:30), rather than adding a cross-section view to clarify, wouldn't it have been sufficient to show the hidden lines in the head-on view?
Yup hidden lines would have helped. There are definitely multiple ways to do it. Another option is just to include a view from an isometric perspective. Isometric views are good for showing the overall form of an object but not so good for dimensioning things. Glad you liked the vid!
im studying mechanical engineering in china in chinese n i dont really understand some of the things my professor says bcz my chinese is not so good yet,sooo this video helped me loads esp the sectioning part,i appreciate...you are just the best
I have a question regarding the part in 12:30, isn't this drawing missing hidden lines on the front view? they would represent the flat part in the middle. And wouldn't that have made the drawing more clear as well? (I'm sent here by a teacher)
This was interesting bc whilst I’ve still got a few years before university I’ve been thinking of what to do and am thinking of graphical design and engineering
cool! Well I wouldn't over focus on mechanical drawing as being the main focus of engineering. This is just a way to communicate. The most important thing is to just start making stuff. Good luck!
Very nice video! You led me to it yourself from a comment on the video about States Machine. The funny story is that I hadn't watched the video if you hadn't mentioned it however, it's the answers to a question I made myself the day before yesterday. It's curious how things turn out sometimes. Thank you for the video!
I appreciate your nice comments Alejandro! I've been out of the habit of making videos for a while, but I expect to make more videos coming up about synthesizers. Have a nice day!
But pls I have a problem I studied maths and physics at high aiming to do automobile engineering so I wish u post videos that can really help a beginner like.i have notes which I'm studying to build my foundation but ur videos will help how to read drawing diagrams I love how u explain things
@@lekonarodrick6821 Thanks for the really nice comment! I won't make any more educational videos in the near future (I don't have a topic that I grasp well enough to make something on). If you want more engineering videos check out StructureFree, that is a fantastic channel!
Good video. Thank you. Why is it necessary to place a dimension to the center of the part when you show centerlines? Also, I was hoping to find a discussion on tangent lines and visible lines. Have you got anything on that?
Glad you liked it! One thing I should have said in the video is don't stress about making every drawing perfect. It only needs to be perfect if you're ordering parts. For communication with your peers feel free to just rough things out.
Nice introduction, but it's short. At 14:28 The threaded part should have a 3/4 circle around the hole in front view and lines for it's boring with the angled tip on the side view. You also could draw the flat spot viewed from top and draw diagonal lines in there.
Sorry I haven't looked up this topic in 5 years or so. When I did I never found a good book, I would just buy a few used text books, read a few pages, then re-donate them. So I can't recommend a good book. Thank you for asking though!
Good question. That’s more advanced than the scope of this video. This video covers “linear dimensions”. For a spline you need to look up something called “geometric dimensions”
The book "How to draw" by Scott Robertson" is a great tool for learning the basics. It includes a bunch of youtube videos, too. I highly reccommend it.
your tolerance for the 2.5 mm long measurements to indicate the center of the shaft perpendicular and horizontal should be 0.025 mm because if you have 0.05 mm then you have a overcontraining right because the other half has a 0.05 mm giving you a total of 0.10 mm tolerance . but in the 5.0 mm or inches long measurement you have only 0.05 mm tolerance. tell me if i am wrong
demo last are you referring to the drawing about the drawing of the bolt that we build up through the video? I don't think it's over constrained. Tolerances on the position of the shaft are unaffected by tolerances in the diameter or length of the shaft. I'll double check with some of my coworkers who are more experienced though.
yes i am referring to that one, see, you have a tolerance -+ of 0.05 on the total left side square , but in the right side you have a -+ 0.05 tolerance for only a half of the distance . i am asking you if this is right cause to me it seems like it should be a 0.025 tolerance even this one is referring to the circle but i am not sure, i am not a machinist but i want to learn. thank you answering my questions.
Hi @Normal Universe - I'm a beginner at drafting and need to create simplistic drawings of two pieces of equipment that I built. I did some research and saw that QCAD or LibreCAD might be my best free options. Do you have any other input or advice regarding which platform to use, if I'm not yet proficient with CAD (and don't need that robust of a drawing). Thank you! This video was amazing!
Hey rogue! thank you for checking with me. I think learning this mechanical drawing stuff is nice for a few reasons. 1) it gets your head in the mechanical mindset 2) This is how things used to be designed a few decades ago 3) Kids can grasp it and you can do it without a computer Long term 3D CAD is more important though. My process might start with a rough sketch using mechanical drawing, but it always goes to 3D CAD for most of the designing. You only need to make mechanical drawings if you are ordering the part from a vendor. Most 3D CAD software will help you generate the drawing from your 3D model. I don't know those two software. I highly recommend you check out Fusion 360 for 3D CAD, it can also make drawings when you need it. What is the purpose of the drawings you need to make?
@@TheNormalUniverse Hey there, thanks for the quick response. I'm guessing we're in the same time zone (both in the EU perhaps!). Anyway, I'm not planning to do anything long term with CAD. I just have one project for a company I'm working with. I need to detail a perforation machine and mushroom substrate pasteurization. I will check out the other 2 platforms, but I'm not trying to buy any parts cause we buy and make everything ourselves.
Awesome video. Small note, I got the first answer a different way, but still don't understand your explanation for the first question at 14:00. After reviewing your explanation a few times I still don't know what ledge you're referencing.
Thanks! When I said ledge, I was referring to the small step next to the hole. I wanted to clarify which side of the part I was referring to, and only one side has the step. Just wondering, how did you find the video?
That's a very nice video. My only criticism with it is that you do not mention what type of projection you are using, which is third-angle projection, used in the USA, Canada, Australia (and the UK partially I think). In Europe and most of the world, first-angle projection is used, in which the side view is put on the opposite side (to the left) of the front view. It might not matter for simple parts like the ones you've shown, but it can potentially produce communication errors. This is why there's always a symbol showing which projection convention is used in the drawing template. en.wikipedia.org/wiki/Engineering_drawing#/media/File:Conventions_of_placing_vues_in_technical_drawings.svg en.wikipedia.org/wiki/Engineering_drawing#Multiple_views_and_projections Still a pretty good job, everything presented is crystal clear, the 3D view at the left and the 2D projection at the right is a nice touch. It must have taken quite some time to prepare. Congrats!
+Normand Chamberland This should be on top! I totally agree. I left that topic out because my thought process was to get people drawing as soon as possible, and didn't want to interrupt the flow by talking about conventions. Hopefully if people get more into drawing from this video they'll learn about it.
Thank you Chris for explaining the 2D you mentioned at 2:00. I should have been able to figure that one out myself!😆 But now I have a sudden taste for Tutti Fruiti ice cream!
amazing video, very professional I wish I had this kind of help when I was in school. Thank you for taking some of your precious time to help and share your knowledge to make others better.
Nestor Mangandi thanks for the nice comment Nestor. It does take a lot of time to make videos (this one took ~50 hours) so I'm glad to hear people like them!
You mentioned studying abroad in Germany... I am currently a high school senior looking to study at the Technical University of Munich, and would love if you could share any tips/advice/experiences different from what you expected . thanks!
Hi Lindsey, I was only there for 3 months in the summer, but it was a delightful experience! I went to TU Darmstadt. I didn't take any classes, just worked in a lab. I liked how Germany had fantastic public transit and really nice walkable areas in even the smallest cities. Europe in general would be really fun to travel around if you went to school there. I can't say if it's better to do Uni in Germany or the US though (assuming you're from the US and considering going abroad). I still miss the Donner kebab
@@TheNormalUniverse High school, 9-12 (all levels are allowed). It is a CAD class and I am trying to ground them in the fundamentals so you can imagine how your lesson very effectively does that.
@@jonathankerner2094 awesome! Ya when I took my first CAD class at Berkeley we just did 2D drawings like this for the first few weeks. I think it helps convey the idea that a big reason of making CAD is communicating your ideas to other people. It's also fun to see how things used to be done before 3D CAD existed.
Wouldn't the first problem be both A and B, since if you were to flip B horizontally (line above the square hole end) and then vertically over (line on the short end) , so that it lays flat against piece A, it could also count as the right side sketch. The only thing would be that you wouldn't be able to to tell that with piece B, the top/short part is sticking towards your view instead of away from you like how it would be interpreted as piece A. However, since the top square line in the left sketch is solid means that the square piece extends forward? In cases like that, could the top line of the square in sketch 2 be dotted to show that the square piece is actually extended from behind instead of forward (to count as piece B)? Kinda typing out my thought process, but would also like a take on this, whether it is possible it could be interpreted that way and also how to make it so that it just counts as piece A. (I think I made it more complicated than it should've been😅)
ElleonOnline hi Ellen! Sorry it’s too hard for me to follow this over text. I should have done a better job making this question clear. The A and B shapes are mirror images of each other, so only one can be the answer. I believe it is A. Don’t stress about it though! For more detail, google “first angle projection” and “third angle projection.” I skipped that topic in this video because it is too boring and not required to learn how to do these drawings. Unfortunately USA and Europe disagree on this topic. Europe uses first angle and USA uses third angle. (This video uses third angle because I am in the USA)
Normal Universe I will look into those topics (even though you say they're boring 😅) Thank you for your reply! I'm still very new to all of this, so I'm going to think about these things more
Normal Universe very informative, I wish you could do more of this type of videos . If you have a link related to this materials please link it below, I will highly appreciate it, thanks.
Good concise and to the point video, but please increase your audio to -3dBTP for future uploads if you haven't already done so. I have to crank the volume wide open in order to understand you, and then get BLASTED by the commercials.
Sorry that happened to you. Audio was hard for me as a noob. It's so frustrating! I'll make a point next time. Maybe I need to redo this video at some point. ¯\_(ツ)_/¯
That's awesome! I suggest you start building things, anything! Sewing, cardboard, arts and craft, whatever. I got my first internship by showing the interview things I made at home.
Can anyone recommend a mechanical engineering book? Preferably one that contains concepts used without computers? I would like to get into some of the basic concepts of it.
awesome! I'm glad you like it. One thing I wish I mentioned in this video is that this method can help you communicate an idea without being good at sketching because you don't have to draw things in perspective.
Good catch! They are, but in the text note. There is a little downward pointing arrow with a "5mm" after it, which is a shorthand way to indicate that the hole is 5mm deep. Sorry for the confusion, that was my fault for not explaining it in the video.
first year of university? Don't put too much weight in what people say! My only advise is to get your hands dirty and start making things. That will put you ahead of all the other students when applying for internships
Thanks! Ya definitely not trying to tell people not to use computers to make drawings, I used a computer to make all the drawings in the video. Just want people to know what they're looking at.
You’re teaching the next generation of engineers… and some 35 year old chancers who need to look like they know what they’re talking about in a few weeks time. 😄
Loved the video! I am a total beginner so this was great, I learned tons in such a short period of time! One thing though - the refernece link in the description box is not working (or is it just me)? Anyways, thank you thank you thank yoou ♡
DroppedOutOf80s I’m glad you liked the video! Sorry the reference link is broken now. I haven’t a found a good replacement. If you find one let me know.
I am teaching in Germany technical drawing. In the example from minute 7.12 are more then 10 elementary errors which are errors in all countries world wide.
oke, now show me how to turn this in a virtual 3d model. Im looking for a quick and easy program to sketch up some designs . it doesn't has to have structural calculation but it would be nice. in metric please
+Cruz Monrreal (Mr. Cruz) Ah I see it, mistake on my part. There should be some hidden lines in the view on the far left. Thanks for catching it. Somepoint in the future I should make a revision of this and fix all the bugs people are catching.

Hello Louine thank you for the request but I’m working on other things now so I won’t be able to do that video. Good luck!
great vid, i would love to see more
thanks for letting me know!
Good video. Thank you. Why is it necessary to place a dimension to the center of the part when you show centerlines? Also, I was hoping to find a discussion on tangent lines and visible lines. Have you got anything on that?
Lol you explained this better than 80% of my mechanical engineering professors. Thanks for the help!
Glad I could help! Thanks for letting me know
3:20 is wrong. It doesn't call out the position of the circular feature. It could be passable if a centerline was used vertically and horiziontally.
The centerline is introduced at 6:00
Great job man! I am now a better mechanical drawing gig, thanks to you!!
I’m glad it helped! Thanks for letting me know
@13:35 I think that neither of the two is correct? A needs to have a dotted line in the front view
Thank you for such a useful video, please don't stop making this amazing material.
Thanks for letting me know Raymundo!
Thanks for details guidance and it will better if you introduce the 1st angle view and 3rd angle view
Glad you liked it! I decided not to cover that topic because it would break the flow of the video, sorry
What is the best book to get about the standard regulations and procedures and practices and modules
Hi Anfeild, unfortunately I don't know of a good book for for that stuff
Amazing video it helped me a lot with understanding the process of mechanical engineering drawing.
Glad you liked it! One thing I should have said in the video is don't stress about making every drawing perfect. It only needs to be perfect if you're ordering parts. For communication with your peers feel free to just rough things out.
can u plzz Show how to draw screw fastening amd joints using dimesions?
Hi Faizan, I'd like to add onto this video in the future, but it won't be for months or years. Check the reference in the video description.
Great video. I look at drawings almost daily and this helps a lot.
Nice introduction, but it's short.
At 14:28 The threaded part should have a 3/4 circle around the hole in front view and lines for it's boring with the angled tip on the side view.
You also could draw the flat spot viewed from top and draw diagonal lines in there.
could you recommend a mechanical drawing book to start learning it?
Sorry I haven't looked up this topic in 5 years or so. When I did I never found a good book, I would just buy a few used text books, read a few pages, then re-donate them. So I can't recommend a good book. Thank you for asking though!
What do u do if my part has a spline
Good question. That’s more advanced than the scope of this video. This video covers “linear dimensions”. For a spline you need to look up something called “geometric dimensions”
The book "How to draw" by Scott Robertson" is a great tool for learning the basics. It includes a bunch of youtube videos, too. I highly reccommend it.
ua-cam.com/video/vFDMaHQ4kW8/v-deo.html .💐
your tolerance for the 2.5 mm long measurements to indicate the center of the shaft perpendicular and horizontal should be 0.025 mm because if you have 0.05 mm then you have a overcontraining right because the other half has a 0.05 mm giving you a total of 0.10 mm tolerance . but in the 5.0 mm or inches long measurement you have only 0.05 mm tolerance. tell me if i am wrong
demo last are you referring to the drawing about the drawing of the bolt that we build up through the video? I don't think it's over constrained. Tolerances on the position of the shaft are unaffected by tolerances in the diameter or length of the shaft. I'll double check with some of my coworkers who are more experienced though.
yes i am referring to that one, see, you have a tolerance -+ of 0.05 on the total left side square , but in the right side you have a -+ 0.05 tolerance for only a half of the distance . i am asking you if this is right cause to me it seems like it should be a 0.025 tolerance even this one is referring to the circle but i am not sure, i am not a machinist but i want to learn. thank you answering my questions.
demo last can you tell me a time stamp to look at so I can be sure we're looking at the same thing?
Hi @Normal Universe - I'm a beginner at drafting and need to create simplistic drawings of two pieces of equipment that I built. I did some research and saw that QCAD or LibreCAD might be my best free options. Do you have any other input or advice regarding which platform to use, if I'm not yet proficient with CAD (and don't need that robust of a drawing). Thank you! This video was amazing!
Hey rogue! thank you for checking with me. I think learning this mechanical drawing stuff is nice for a few reasons.
1) it gets your head in the mechanical mindset
2) This is how things used to be designed a few decades ago
3) Kids can grasp it and you can do it without a computer
Long term 3D CAD is more important though. My process might start with a rough sketch using mechanical drawing, but it always goes to 3D CAD for most of the designing. You only need to make mechanical drawings if you are ordering the part from a vendor. Most 3D CAD software will help you generate the drawing from your 3D model.
I don't know those two software. I highly recommend you check out Fusion 360 for 3D CAD, it can also make drawings when you need it.
What is the purpose of the drawings you need to make?
@@TheNormalUniverse Hey there, thanks for the quick response. I'm guessing we're in the same time zone (both in the EU perhaps!). Anyway, I'm not planning to do anything long term with CAD. I just have one project for a company I'm working with. I need to detail a perforation machine and mushroom substrate pasteurization. I will check out the other 2 platforms, but I'm not trying to buy any parts cause we buy and make everything ourselves.
Awesome video. Small note, I got the first answer a different way, but still don't understand your explanation for the first question at 14:00. After reviewing your explanation a few times I still don't know what ledge you're referencing.
Thanks! When I said ledge, I was referring to the small step next to the hole. I wanted to clarify which side of the part I was referring to, and only one side has the step.
Just wondering, how did you find the video?
That's a very nice video. My only criticism with it is that you do not mention what type of projection you are using, which is third-angle projection, used in the USA, Canada, Australia (and the UK partially I think). In Europe and most of the world, first-angle projection is used, in which the side view is put on the opposite side (to the left) of the front view. It might not matter for simple parts like the ones you've shown, but it can potentially produce communication errors. This is why there's always a symbol showing which projection convention is used in the drawing template.
en.wikipedia.org/wiki/Engineering_drawing#/media/File:Conventions_of_placing_vues_in_technical_drawings.svg
en.wikipedia.org/wiki/Engineering_drawing#Multiple_views_and_projections
Still a pretty good job, everything presented is crystal clear, the 3D view at the left and the 2D projection at the right is a nice touch. It must have taken quite some time to prepare. Congrats!
+Normand Chamberland This should be on top! I totally agree. I left that topic out because my thought process was to get people drawing as soon as possible, and didn't want to interrupt the flow by talking about conventions. Hopefully if people get more into drawing from this video they'll learn about it.
Thank you Chris for explaining the 2D you mentioned at 2:00. I should have been able to figure that one out myself!😆 But now I have a sudden taste for Tutti Fruiti ice cream!
I deleted my previous question because it was rather embarrassing.😖
amazing video, very professional I wish I had this kind of help when I was in school.
Thank you for taking some of your precious time to help and share your knowledge to make others better.
Nestor Mangandi thanks for the nice comment Nestor. It does take a lot of time to make videos (this one took ~50 hours) so I'm glad to hear people like them!
In our days it was only from our teachers but now you can learn from UA-cam.This also reminds me when I was a teacher in the high school in Ghana 1992
You mentioned studying abroad in Germany... I am currently a high school senior looking to study at the Technical University of Munich, and would love if you could share any tips/advice/experiences different from what you expected . thanks!
Hi Lindsey, I was only there for 3 months in the summer, but it was a delightful experience! I went to TU Darmstadt. I didn't take any classes, just worked in a lab. I liked how Germany had fantastic public transit and really nice walkable areas in even the smallest cities. Europe in general would be really fun to travel around if you went to school there. I can't say if it's better to do Uni in Germany or the US though (assuming you're from the US and considering going abroad). I still miss the Donner kebab
An outstanding video that my students are benefiting from. Thank you!
Thanks for letting me know Jonathan! What grade of students are you teaching?
@@TheNormalUniverse High school, 9-12 (all levels are allowed). It is a CAD class and I am trying to ground them in the fundamentals so you can imagine how your lesson very effectively does that.
@@jonathankerner2094 awesome! Ya when I took my first CAD class at Berkeley we just did 2D drawings like this for the first few weeks. I think it helps convey the idea that a big reason of making CAD is communicating your ideas to other people. It's also fun to see how things used to be done before 3D CAD existed.
thank you for teaching me :) i felt behind my class this morning but i think i'm good now
MrSuperrajab thanks for letting me know! Are you from Michigan State University? I see traffic from their website once in a while
Thank, thsi was a super useful video, very clear, concise, yet information rich and informative
Thanks for letting me know Hugo!
Wouldn't the first problem be both A and B, since if you were to flip B horizontally (line above the square hole end) and then vertically over (line on the short end) , so that it lays flat against piece A, it could also count as the right side sketch. The only thing would be that you wouldn't be able to to tell that with piece B, the top/short part is sticking towards your view instead of away from you like how it would be interpreted as piece A. However, since the top square line in the left sketch is solid means that the square piece extends forward? In cases like that, could the top line of the square in sketch 2 be dotted to show that the square piece is actually extended from behind instead of forward (to count as piece B)?
Kinda typing out my thought process, but would also like a take on this, whether it is possible it could be interpreted that way and also how to make it so that it just counts as piece A. (I think I made it more complicated than it should've been😅)
ElleonOnline hi Ellen! Sorry it’s too hard for me to follow this over text. I should have done a better job making this question clear. The A and B shapes are mirror images of each other, so only one can be the answer. I believe it is A. Don’t stress about it though!
For more detail, google “first angle projection” and “third angle projection.” I skipped that topic in this video because it is too boring and not required to learn how to do these drawings. Unfortunately USA and Europe disagree on this topic. Europe uses first angle and USA uses third angle. (This video uses third angle because I am in the USA)
Normal Universe I will look into those topics (even though you say they're boring 😅) Thank you for your reply! I'm still very new to all of this, so I'm going to think about these things more
13:45 You turn right on both when walking away from the hole. Unless it was flipped upside down, maybe?
Is Mechanical drawing need to applying scale ? if so what drawing scale ?
Depends on the size of the object and the size of the paper you are using. Just use what scale fits best, there is no set scale.
This video is great. It teaches slowly how a mechanical drwaing is and it's parts. It is also entertaining. Nice work😁
Made it easy for a newbie like me to understand
Thanks Sean! I always like to know when my videos are helpful
Is there a way to patent cheaply?
wow, thank you for this, i am learning all by my self.
E Ndongo thanks! How did you find the video?
Normal Universe very informative, I wish you could do more of this type of videos . If you have a link related to this materials please link it below, I will highly appreciate it, thanks.
Good concise and to the point video, but please increase your audio to -3dBTP for future uploads if you haven't already done so. I have to crank the volume wide open in order to understand you, and then get BLASTED by the commercials.
Sorry that happened to you. Audio was hard for me as a noob. It's so frustrating! I'll make a point next time. Maybe I need to redo this video at some point. ¯\_(ツ)_/¯
But thanks for letting me know you liked the vid!
Im 11 and im going to be an engineer! Thanks for the help!
That's awesome! I suggest you start building things, anything! Sewing, cardboard, arts and craft, whatever. I got my first internship by showing the interview things I made at home.
Can anyone recommend a mechanical engineering book? Preferably one that contains concepts used without computers? I would like to get into some of the basic concepts of it.
Check out structure free on youtube, I'd start with his playlist on Statics: ua-cam.com/users/structurefreeplaylists
Thanks!
I study mechanical engineering and I can't sketch at all but your video really helped me, thank you so much
awesome! I'm glad you like it. One thing I wish I mentioned in this video is that this method can help you communicate an idea without being good at sketching because you don't have to draw things in perspective.
In the last question the depth of holes are also not dimensioned sir.i have very little knowledge but I m just asking.
Good catch! They are, but in the text note. There is a little downward pointing arrow with a "5mm" after it, which is a shorthand way to indicate that the hole is 5mm deep. Sorry for the confusion, that was my fault for not explaining it in the video.
Thanks sir.learned honesty also from u.
Hello Boston University! I see you :P (analytics tells me people are coming from bu.edu)
Great intro to technical drawing, thanks so much!
13:19 Do you have that in image/PDF/etc form?
+Allen S Sure, send an e-mail to thenormaluniverse@gmail.com
Is it too late to start at twelve?
ua-cam.com/video/vFDMaHQ4kW8/v-deo.html .💐
wow thanks, there are many things you have talked about that will help in my engineering course
glad you liked it! I can't believe how many people are learning drawing from the video. How did you find it?
I'm about to start mechanical engineering this year. I'm terrified because everyone says I cant do it.
first year of university? Don't put too much weight in what people say! My only advise is to get your hands dirty and start making things. That will put you ahead of all the other students when applying for internships
@@TheNormalUniverse yes, university. And thank you I really want to make the most of this year
Love the vid but is a tad quiet
Thanks for the feedback. Ya I made this video when I was still new to audio editing. I'll do better in the future.
Uno de los mejores videos, muy clara la explicacion muchas gracias
De nada! gracias
Engineers always deal with massive drawings,and this will enable artisan to do excellent work
Thanks! Ya definitely not trying to tell people not to use computers to make drawings, I used a computer to make all the drawings in the video. Just want people to know what they're looking at.
I did not understand the answer of question 1
please make another video on understanding tolerances!
Thanks for the encouragement! I'll keep that in mind. I think I need to learn more about tolerancing before I can teach it well.
Great video -- can you update the reference link, please? It seems broken... Thanks!
Ack that link is broken and I haven't found a good substitute. I updated the description to reflect this. Thanks for letting me know.
You’re teaching the next generation of engineers… and some 35 year old chancers who need to look like they know what they’re talking about in a few weeks time. 😄
glad I could help! Thanks for lettimg me know
yep, this rocks
Thanks! Encouragement is greatly appreciated
Loved the video! I am a total beginner so this was great, I learned tons in such a short period of time! One thing though - the refernece link in the description box is not working (or is it just me)?
Anyways, thank you thank you thank yoou ♡
DroppedOutOf80s I’m glad you liked the video! Sorry the reference link is broken now. I haven’t a found a good replacement. If you find one let me know.
You earned my subscription :).Keep up the good work.
Nilesh Sutar yeehaw! More videos coming in a bit.
I am teaching in Germany technical drawing.
In the example from minute 7.12 are more then 10 elementary errors which are errors in all countries world wide.
DrDicht86 can you please point out some of them? I can try to fix it.
Thank you!
Thanks for letting me know you liked it!
thank you sir!
You are welcome!
oke, now show me how to turn this in a virtual 3d model.
Im looking for a quick and easy program to sketch up some designs
. it doesn't has to have structural calculation but it would be nice. in metric please
Check out Fusion 360. It's awesome and free for hobbyists.
Why did your drawing at 13 mins not show the hidden lines of the tabs?
+Cruz Monrreal (Mr. Cruz) Ah I see it, mistake on my part. There should be some hidden lines in the view on the far left. Thanks for catching it. Somepoint in the future I should make a revision of this and fix all the bugs people are catching.
+Normal Universe No worries. It was a very well done instructional video nonetheless.
