Orthographic projection - Engineering drawing - Technical drawing

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.

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.

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

[@technicaldrawing]

In this question in length take radius because distance is given till the centre line and in width we will take diameter

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
