- Orthographic projection is a method of representing three-dimensional objects in two dimensions.
It is generally used by
Engineers, designers, architects, and technical artists to help a manufacturer understand the specifics of a product that needs to be created commonly use it.
There are 2 types of orthographic projections
(1) First angle method of Projections and
(2) Third angle method of Projections.
What is the difference between the 1st angle and 3rd angle method of Projections?
The difference between the first and third angle projection is in the position of the Top, Front and Side views.
Why we can't use the 2nd and 4th angle projection?
Note: Overlapping projection views creates confusion in the drawing. Therefore, the Second angle method of projection and Fourth angle method of the projection system are not used.
The Third angle is mainly used by the USA and CANADA and Entire EUROPE and Rest of the world use First angle method of projection
Some people also say orthogonal Projections.
Advantages of using orthographic
(1) You can show hidden detail and all connecting parts.
(2) You can show all dimensions necessary for manufacture.
Limitations.
Orthographic drawings do not show depth or realistic views.
A single-view orthographic drawing represents every object as having only two dimensions.
In orthographic projection, there are six possible views of an object, because all objects have six sides - front, top, bottom, rear, right side, and left side.
Typically, an orthographic projection drawing consists of three different views: a front view, a top view, and a side view.
Occasionally, more views are used for clarity.

i love u; you've saved me... i didn't attend my engineering class that explained orthographic projection and my university's digital material was so lacking everywhere; i'm very grateful i found this video.
Thanks so much for well explained TD , please bring us more
Thank you so much for this wonderful information. Stay blessed.
this is some next level asmr stuff. video helped a lot btw
great tutorial with calm music and everything, so easy to watch and also very informative. Plain and simple, thanks
dont lie its
so fast
ok your explanation is very wonderful , you capable to explain the informations with very easy . Really you are creative . Thank you very much my heart dear
you are a so humble teacher..very well explained sir.Thanks a lot.
Very clearly explained...😊
Good job . easy to understand.
This one is awesome.Please do the videos with pictorial drawing
Helpful thanks 🙏
Nice and interesting.
Daughter is freshman in engineering. Making her learn this because I’m dad engineer and had to learn this when I was a freshman 😂. Makes transitioning to Solidworks and etc. easier. Been using your lessons because I am lazy and don’t have the text books anymore. But I see a mistake in this projection that will give the machinist an aneurism. The portion where the gusset intersects the semi circular part at the top does not work as drawn. The gusset cannot intercept the top flat as drawn. The curvature will cause the edges of the gusset to extend above the top flat because of the circular intercept. The way I drew it I had the top milled to correct vertical dimension which leaves a small extension on either side of the gusset. I kept the 22mm to the circular intersection shown as a hidden line but the I slid vertical line about 1mm to show proper intersection. I didn’t measure, just projected it. BTW these lessons are great and reminds me of the pride and enjoyment I got from producing these drawings back in the day. Cheers.

amazing thank you soo much
Good explanation
thank you very much sir🙏
So good 🙏🙏❤❤
you're the best
You are helped me much . Thank you very much
Great work ! really helpful :)
In some drawings the center line isn't extended to touch the border in some it is which is correct or is there a reason for the difference?
There is no reason you can draw full centre line
What about the lines you drew before,,,the plan diagram
Thank you sir.....
How did you use the right angle And meter rule to acquire the correct measurements
I have cm scale
What and what do I need to buy to learn sir
Thank you for the great tutorial. I've one drawing here I need to do the autographic drawing please I need your help.
Sure
Very Nice proramm
How do you draw your center lines
Ratio is 8 -2 - 8
why didnt you draw a center line by the side view for the curve or is it defined as a hidden object
you can draw
Can you do a toy car (side top front rear) next?
Does your channel have videos for 1st year Engineering drawing? Orthographic
Yes
@@technicaldrawing where I can’t find it
Im lost sir where are you getting that side view from
Left hand side view ... you see the object from left side
Thnk u sir❤️
Nice please is there a way I could send you an orthographic projection I’ll like to see your solution on the channel
You can email me on sachinpandya2602@gmail.com
Excuse me how did get your measurements with a meter rule
I am using big scale only to draw lines dimensions are marked with yellow scale
🙌🙌
Nice 👍 for dhat td
Thank u😊 😊
Nice
It's great 👍.
But measured numbers are not seen well
Yes will keep in mind for my future videos
Wow
Please asnwer
Q1)The projection originated from the 3d object itself to project on the plan in front of it, is called_________.
a) First angle projection b) second angle projection
c) third angle projection d) fourth angle projectio.
.
Q2. The projection originated from from the eye ball and converted into 3d object to project a 2d image on the plane is the
(a) 1st angle projection (b) 3rd angle projection (c) 2nd angle projection (d) 4th angle projection
.
Q3. when the surface is inclined to two of the planes of projection ( but perpendicular to third) the surface is said to be (A) Auxilliary (B) Skewed (C) Oblique (D) Angled (E) Primary
.
Q4: actually show the full size of view (A) Axonometric projection (B) Orthographic projection (C) oblique projection (D) Isometric projection
Sir tomorrow is exam and i am confuse while taking length breadth and height while calculating length do we have to calculate given information in radius or in diameter? Same confusion for breadth and height please reply sir
In this question in length take radius because distance is given till the centre line and in width we will take diameter
@@technicaldrawing thanku sir ❤️
How did you do?
0:21
Perfect explanation thanks a lot
Sir I have a question plz answer sir in side view the longer doted line what it is showing and how much distance between hidden circle in side view plz answer me I have lab evaluation
Those long vertical line represents the edge which we can't see in side view total width is 60 and those those dotted lines are 15 mm on both sides of AXIS
@@technicaldrawing thanku
Thank you so much, sir. I would like to ask something, would that be okay if I send you a 3d body and ask you to draw the Orthographic projection of it. I guess the one I have is more difficult than the one you solved.
I would be delighted if you answer sir.
Thank you.
Best regards.
Yes please!
Excuse me sir he can you tell which is top view , front view please
Upper one is FV and lower one is TV ... It is in 1st angle method
Can I have measurements of side view the rectangle
Ht is 45, and the width is 60
Good
Thanks
when a surface is incliend to two of the plans of projections but perpendicular to the third, the surface is said to be _________.
1) Axiliary
2) sekewed
3) obligue
4) angled
please answer

чел.. где ты был раньше
You make it very easy 🫡
And please Sir, am having my exams tomorrow and I want to refresh and so I decided to watch this video only to become confused
Sir, its top V will come up in the third angle?
Yes
Please can you draw full drawing
Can you explain more...
thankss wtching this before my exam lol
All the best

You're not explaining well, am somewhat confused on how you drew the half and full circle, like what measurement did you use in drawing each of them
Good work❤. Please the scale am not understanding it.
Calculation part? Or construction part
@@technicaldrawing good morning sir.
When you are saying here is 60 I does not understand the length. Is it in cm or mm or Inches?

Yes

Hello 👋
Hi
Thx
What a hell is the question
This is incorrect, the top view is placed above the front view.
I am following the first angle method ... I guess you are talking about third angle method
@@technicaldrawing OK, you are correct!

Your LV is not exactly 100%. Please review it, I see minor error to be corrected.
Is it working error or concept error
