Intro the Mechanical Drawing Video [15 minutes]

[Bokononestly]

I've gotten some great help from this forum, so in return I wanted to share a video I put together on the basics mechanical drawing. It covers line types, multi-view layouts, linear dimensioning & tolerancing, and alternate view types.

It's so easy to get nit picky and dive into things you overlooked to be fully standard compliant etc. but if you even tried to do that the video would probably me much longer and harder to follow.

So rather than throw stones at what you did create, when I created nothing, I'll just give you a 'nice effort'.

Folks over in forum1103 forum might be interested, but you'll almost certainly get some nit picking.

I got a "nit pick" about hidden line . Hidden lines should not touch solid lines and I found this out when my freshmen college ME instructor back in the early 60's knock off five points from my grade and while I was really miffed that lesson I never forgot. Now, I know that when you use AutoCAD hidden lines will touch solid lines automatically and today such error may seem trivial but it is a point to remember for the students.

With regards to the drawing example discussed in the final portion of your video, none of the part features were fully defined. If you're going to produce a video with the intent of teaching people the correct practice for creating engineering drawings, you need to learn more about the subject yourself.

Thanks for watching and feedback! I should have said earlier, but ya this is targeted at interested students, I didn't expect to be teaching anything new to most people here.

Interesting point Chicopee, I didn't know that.

You're right tbuelna. I didn't have time to fix that drawing before leaving on a 2 week vacation (I had already put in about 40-50 hours). In the end there's a review question that asks "can you spot the missing dimensions in this drawing from earlier?"

Maybe I'll do a version 2 in the future to fix these mistakes.

Bokononestly-

I started out 30 years ago working for an aerospace OEM as an entry-level draftsman. The most important thing I learned during the first few years on the job was paying attention to details and making sure to check my work for errors before submitting it to my manager. The engineers back then were definitely old-school, and they did not tolerate sloppy work or obvious mistakes. If I were to submit an incomplete engineering drawing (like the one in your video) for release, my manager would chew my butt out for wasting the company's money.

The most valuable lesson you can offer with your video is teaching people the importance of paying attention to details and doing as thorough a job as possible with their work. Rather than doing a job as quickly as possible, they should focus on doing the best job possible. Even when they are doing the most simple or mundane tasks.
