Engineering Drawings: How to Make Prints a Machinist Will Love

Making drawings is a skill that any practicing engineer needs to master. Unfortunately, it's not something that is taught very well in most engineering schools. In this video, we're going to try to demystify engineering drawings and give you some tips and best practices to make clear, complete drawings.

In this video, we'll discuss
- The different types of engineering drawings
- The features of a standards-compliant drawing template
- Choosing and placing views
- Strategies for dimensioning common features
- Tips to improve the clarity of your drawings
- The relevant ASME standards
- Example detail and assembly drawings of REAL parts

Companion blog post with reference sheet, sample drawings, and checklist:

Want more on Engineering Drawings? We just made a full 1.5 hour LinkedIn Learning course: Engineering Drawings for Manufacturing. You can find it on our website: www.tarkka.co/drawings Thank you all for the support, and we are coming out with more YouTube videos soon!

I'm a mechanical engineer and former toolmaker and was expecting some clickbait, annoying youtube music video, but I was positively surprised. A lot of very good and helpful information for newcomers and unfortunately for some senior engineers too. Nice channel, keep it up.

That's an international problem now: "Most universities do an awful job teaching the concept". Here in Chile, the same.

The pace of narration...summed up very that are unreasonably tight"

I worked as a draftsman, checker, engineer and even taught drafting in jr college. This is the best lesson I've ever seen anywhere. Excellent.

It's 2AM. Youtube, for the love of God, why did you recommend this video? Now I want to design brake calipers.

[neotsz]

I'm not even in engineering, but I still watched the whole thing. Good job in condensing the information!

As a machinist I cannot thank you so much for making this. I hope all engineers heed this advice. I hate when a drawing is missing something and then I call the engineers and they get annoyed with me 🙄 like really

[ChrisCiber]

I felt more informed by this one video than the entire Drafting/CAD class I took

[blazianable]

Just discovered your channel via your reddit post and let me just say this is THE channel I've always hoped for! Don't stop making videos, they're very helpful!

In the past you never had to take drafting classes to be a mechanical engineer. When the computer drawing systems came out, they fired all of the draftsmen and gave the engineers software manuals. The software manuals do not teach fits and clearances. If you do not understand fits and clearances you can not properly dimention a print. Frenches Engineering, And Gisec Mitchell and Spencer were my textbooks from the seventh grade to navy illustrator draftsman A school. Fits and clearances is based in the principal that "two objects can not occupy the same space at the same time".

As a machinist, I thank God for this video! Sending this to all of the engineers I work with 🙄 How annoying it is when I have to deal with engineers with no machining experience who draw parts that are near impossible to machine. Thank God for you guys making detailed explanation videos!!!

[benjaminkinga]

This is an under-appreciated channel. I hope you continue making more content

[edwinmerino]

Best engineering channel hands down. Just stumbled across your o-ring video (knowing little to nothing about o-rings) and was blown away at the quality of information per second you were spitting out.

[denisl]

My company needs to send all the engineers to remedial school and make them watch all your videos.

"Hey so this part that I'm making on a manual mill has a 0.171875" dimension, are you sure that's correct?"

"Oh yeah, just get it as close as possible it'll be fine."

This is actually an amazing small walkthrough of technical drawings, I had a class on it last semester in uni, and this is great for refreshing what I learned there.

[drakenburg]

I can not stress how much a channel like this was needed on Youtube. Absalutely brilliant guys! My new favourite channel.

[Andronicus]

Great video. I'm going to make this video a part of my on boarding curriculum for new engineers.

[RandDickson]

My solid modeling class was 2 years ago and only part of it concerned drawings. Thanks for the refresher!
