Understanding Engineering Drawings

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

[@sunfishMola]

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.

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'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 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
