+Sagar Parekh Thanks, appreciate the support. These can take a while to make compared to the old overhead camera, hand & pen effort, so glad these have proven so popular.
Excellent description and demonstration of 1st and 3rd angle projections. My students will surely be able to understanding it better after viewing your demonstration!
New to engineering and this is one of the main points of focus. I've been looking at tons of videos and diagrams...nothing has made more sense to me than this video. Thank you for the clarification. Now if only I knew WHY we have to have two different styles. USA for ya. As if ditching the metric system wasn't enough! 😅
This video is excellent for explaining this concept. I didn't understand it from even your first video but with the graphic representation here everything clicked. Thanks!
So helpful! I was struggling with First and Third angle of Projection. Found this video and it really helped me with getting my head around the concepts; would always recommend!!!
Thanks, that's exactly what I was aiming for, good to hear it's also how it was received! Too often this is made more complicated by its explanation than it actually is. More to come.
I've watched several other videos on this issue (all newer) but find your vids to be the best of the bunch. My only suggestion is that a different shape for either of the tubes (eg. rectangle) might be easier to recognize by people who have less experience in reading plans. Other than that, thank you for the timeless explanation and outstanding graphics.
1st angle projection is as if you're rolling the part, 3rd angle projection is as if you're unfolding the part. I came up with "spring roll" to remember which is which, spring is the first season (angle) so the part is rolled.
I'm always surprised by how much the question on 2nd and 4th is raised online. In nearly 8 years of lecturing CAD, I've never ran into it in person. I'm thinking of doing a video on it, as I know the issues when following the cartesian quadrant model strictly by math (views clash during folding), but equally what it 'could' functionally appear like if we were to just tweak how we resolve the abstraction. (fold differently)
A few years late here, but... The idea of 1st and 3rd comes from the four quadrants of space (think back to x-y-z coordinates in school, and how mathematicians often speak about 1st quadrant, etc.). For 1st angle projection, imagine the part placed in the 1st quadrant of space. The views we draw are the images as projected onto the coordinate planes. For 3rd angle projection, the part is placed in the 3rd quadrant; if you can visualize this, then you'll see that the projected views will be different than 1st angle. As for your question -- we could place the part in the 2nd or 4th quadrant (so 2nd or 4th angle projection are possible), but they would merely be a hybrid of 1st and 3rd. So they never really caught on.
Thanks for the video. Now, is there an actual reason why first angle projection is preferred in some countries/regions? It seems like third angle projection is more intuitive.
Cheers, yeah I'm well aware of the audio in my earlier videos. I reckon I got a lot better (see something like the section view video). The problem is TH-cam doesn't allow replacing videos and keeping view metrics etc. Even if the content is functionally the same but at better quality. Since TH-cam will send you more viewers the more engaged with videos are, re-uploading these and starting at 0 would likely not see the same success. I am however looking to work on the channel more, and once I feel it can stand on it's own, I'll gladly replace these with higher polish.
That's entirely based on local standards/preferences of specific countries. There is no substantive reason to use one over the other, just local preferences. However by international standards at least, there isn't anything wrong with using either as long as the correct symbol is used to identify as such.
+Clan MacCAD here is the rule - First Angle = what i see from the top is what i have to draw - Third Angle = just drawing every face in the same place mean right face at right, left face at left.... right ?
+Abody tube² In both cases, it is about which side of the real 3D object appears in which 2D view. In both cases you start with a front view. (the middle one in each example). The difference between third and first angle is purely what you do when adding more views to the sides and above/below. In First Angle - if you had the object on the paper physically. The views are laid out as if you roll the actual object over in the direction of the next view you want to create. Therefore the opposite side you would expect ends up face up. In Third Angle - if you also had the object on the paper. it is as if you pull out the nearest side of the object to the view you want to make Everything in both cases is a 90 degree rotation. You could try practicing on real paper with a practice object at home. However remember all I am describing here is the two different ways to lay out the views. If you don't know how to create the views themselves yet, it may be too soon to try and understand this.
USA use third, UK use first traditionally, ISO (international) has trended towards third, but both are valid and should really have the correct symbol on display.
This was a really good way of showing the difference between the 2. It really helped to visualize the difference.
I've been a machinist for 25 years and you nailed it!!!!
Best video on TH-cam explaining 1st angle n 3rd angle projection. Good job..keep it up.
+Sagar Parekh Thanks, appreciate the support. These can take a while to make compared to the old overhead camera, hand & pen effort, so glad these have proven so popular.
Bhai ekdau sahi bole aap ...
Yes ur 100% told correct
A simple and clear demo like this is so much better than reading it off the notes. Thanks!

So far all the videos I have seen have been of very high quality and the subjects explained clearly. Well done.

Very clear, great way to demonstrate the differences
EPIC VIDEO ! I was completely lost before I watched this video ! Bless you !
best video on Engineering Drawing Introduction must watch
th-cam.com/video/HtXz58Low_w/w-d-xo.html&feature=share
Clan MaCAD you are my hero. Liked and Subscribed. You teach this better than any book I have read on technical drawing.
Ultimate quality and explanation...
For a moment i thought i went into future!
You kept the explanation very simple and also practical. Very well done.
Thanks, that's exactly what I was aiming for, good to hear it's also how it was received! Too often this is made more complicated by its explanation than it actually is. More to come.
This didn't click until I saw it done in 3D. Nice work and thank you very much!
Clan MacCAD... This is by far the best explanation I have heard!!. Plz keep it up
I've watched several other videos on this issue (all newer) but find your vids to be the best of the bunch.

Great video and explanation. Short and to the point. Well done.
So glad I found your channel by far the best explained examples teaching this, fantastic. Thank you you much!!
What a great video you saved my hours.
Very useful... much better than my Uni books!!!
SO HELPFUL THANK YOU!!!!
Very well done. Best explanation on you tube. Will show this in blueprint class. Thanks
At long last I get it, thank you so much for this video to explain such a simple concept, otherwise made quite complex in other videos.
Great explanation and visuals!
Great Video so much clarity with first two videos. explained and understood perfectly thank you.
Perfect Visual. Thanks!
You're more than welcome!
Thanks! Best video Ive seen on the subject!
Great explanation and demonstration.
Perfect explanation!
Thanks! Glad it was helpful, got more ideas on general drafting practice coming in the next few weeks.
Fantastic demo!!
Thank you so much for this video, very useful and explained very well.
A simple and perfect explanation videos.
Thank you, nice explanation :)
Thanks! This was really helpful

Animation is very Understanding
This is a super helpful video, thank you.
This video is really very helpfull Thank you so much sir
Lucidly done
thanks for your videos man, they really help!!
amazingly explained
The best. Great job!
u deserve more subscribe
Absolutely fantastic
Thanks. Very easy to understand.
best explanation so far, but both seam weird to me.
i would like an explanation of 2nd , and 4th angle...... id probably choose one of those.

Perfect angle view
this is the best. congratulation
Good Job Mate
In simple words, if you tilt an object above the plane of paper u get 1st Angle while tilting it below the plane gives 3rd Angle. Thanks
Soo helpful ❤
thank you sir for this video..
Nice video, helpful everyone
So good! Thank you!
Great video sir
Well explained
Nice, Excellent
thank youuu, very useful!
Which software was used to show the difference
Hello, Is there a way to get in contact with you about this tutorial?
Great explanation!
And I love visuals! What program/programs did you use in order to get such a nice video?
❤❤❤
Ty so much sir 🙏🏻
That was useful. can you please explain in 3d why we dont use 2nd and 4th angle projection

Great work!
Could you please tell me what software did you use for making this video?
Thanks for the video. Now, is there an actual reason why first angle projection is preferred in some countries/regions? It seems like third angle projection is more intuitive.
Great video Thanks
which software is used to create this video ?
+Tejas Suthar 3Ds MAX was used, then edited in After Effects to add audio and export.
I've got a Design midterm tomorrow.This video is going to make me pass.
+Animesh Jha Happy to hear that! Good luck!
Great explanation. Audio quality needs improvement--too many artifacts of digitization.

I am still confused when and where to use 1st angle view and 3rd angle view...

However by international standards at least, there isn't anything wrong with using either as long as the correct symbol is used to identify as such.
Good 👍👍👍👍
thank you...
Please make new video of animation
awesome
Gracias.
good
still not sure if i got it hhh
+Abody tube² Ok, What aspect do you think your still struggling with? remember this is just covering orientation between views.
+Clan MacCAD here is the rule
- First Angle = what i see from the top is what i have to draw
- Third Angle = just drawing every face in the same place
mean right face at right, left face at left....
right ?

Russia use first
Japan use third.
And about USA ???
USA use third,
UK use first traditionally,
ISO (international) has trended towards third, but both are valid and should really have the correct symbol on display.

awesome
