book on doing tech drawings

[krw]

There are only a certain number of things one can fit in the head. We have so much that one needs to know and only so much time to learn, something's got to go.

[krw]

That's quite a difference. Math and language a prerequisites for life today. Unfortunately they're not taught in schools anymore. They've been replaced by _Heather_Has_Two_Mommies_.

Again, a whole different universe.

[Emanuel Berg]

OK, interesting. Well, I'd like the drawing to be correct at all points, technically, but it can be super simple at first, that's good even. And correct terminology all thru. And examples (drawings). That's it :)

Like learning English from 0. First lesson is just one word. "Hello". Well, OK, that _is_ correct English! Then it progresses, and new concepts are introduced. That would be ideal.

[Emanuel Berg]

Argh, so many suggestion... why don't you guys decide on onee book? I'll be happy to order that.

:)

From my perspective, technical drawing varies a great deal with context: From a nut and bolt or motor assembly, kitchen cabinets, or city streets (with sewers and water mains). I think they each have their own standards (nomenclature?). If any software developers are watching, it is interesting to compare/contrast with UML (Unified Modeling Language).

[Emanuel Berg]

They teach it here at many levels. At the university perhaps theory-only by now.

I did it year one at "gymnasiet" which maybe equals your "Sophomore year" [1] - don't remember much, mostly the sliding ruler set we used. And a very thin disc with holes to do precision erasing :)

Sorry for improvised (incorrect) terminology... please correct.

But at least _after_ the education in the 65-70ish you got a good job, right? Which would pay for them books many times over?

Poorly written books never good tho, 1965 or 2021 equally bad.

So pick an area, style of drawing you want to do. Each is like a different language.

Mechanical drawing is similar but quite different from architectural drawing. The lettering is substantially different as are the end points of dimension lines. Pipe fitting drawings are different too as are electrical schematic drawings. Basically an architect would probably fail miserable at providing a machinist a drawing that meant anything or for that matter provide enough detail.

Aside from that there are rules that apply to dimensions as well as the drawings themselves. Then there are line weights for each. Then there are cross section views that are different.

And aside from all of that there are rules for placement of all of the views on a drawing and then add in isometric views and their exact placement.

It is a good thing to learn the basics to drawing with a drawing board but you can, for your own needs, progress further and faster using a computer and say, Sketchup.

[Leon]

LOL, That would be like asking for a suggestion to learn a language and not indicating which language you want to learn.

[Leon]

LOL, I used Lotus 123 up until about 6 years ago, from about 1990. Then learned, sort'a learned Excel, I get done what I need to get done. ;~)

Parallel, however.

They also get rudiments of mechanical drawing, measurements, bluprint-reading, etc., etc., etc., ...

I repeat--

"... we know it is what the employers want because they sit on the program advisory boards and make both financial and technology contributions to programs that provide the training they're looking for in graduates."

If you want to teach a course-specific training in a given CAD package (or Excel or Quickbooks); that's possible and there are classes for the purpose but it's not a general curriculum.

I don't believe I've ever used that function nor see the need, at least in that way. A column of numbers, sure, but I just paint them.

[krw]

Not at all. One is very specialized knowledge, the other set is foundational. Nothing gets done without it.

Maybe but they're people who were brought up needing that rot. The "GET OFF MY LAWN" crowd.

Bullshit. 3-D modeling, and specific programs, *are* taught in technical colleges and universities. We don't just grow mechanical engineers on trees. Even if only one particular program is taught, the skills are transferable. There is a limited set of professional packages so chances are good that the knowledge will be immediately usable.

If by "general curriculum" you mean to liberal arts majors, no, they're too busy canceling real people.

[krw]

You do today, in those fields (veterinary medicine and electrical engineering) ;-)

Good point. Good textbooks are hard to find anywhere. I found many are good once you know the subject but are Greek to the sophomore.

[Emanuel Berg]

Not anymore!

Well, it depends. Power tools, certainly but actually not always. If you have the charger and batteries already it can be the same, virtually, as some books put out today.

Precision instruments like torque wrenches - sometimes. Good enough for government work Made in Taiwan that I got is less expensive, or right around what people give for a university textbook. (There are super-expensive torque wrenches as well, of course. And spoke tension meters for more than 10 000 SEK ???)

But, the last three tools I got: knife to cut rope - ~100 SEK, Nail Puller - 200 SEK, crowfoot - below 100 SEK, folding rule mm/inches - below 100 SEK, hand saw [1] - 70 SEK, sure, really expensive hand tools like Knipex power pliers Made in Germany and stuff - OK, that's true - but a big book on science/technology can by 600-800 SEK as well! Easily!

[1] The hand saw is 7 teeth 8 points, I understand that definition but why is the 8 points relevant, what does it tell that is useful that 7 teeth doesn't tell already? Do you know? It bugs me I can't figure it out...

[krw]

Obviously English. Learn that and you've learned all of the others, since English is a language stolen from a hundred others. ;-)

OK, it has some special (read; weird) rules not found elsewhere, like order of adjectives. Get them out of order and you sound like a true moron (but no one can tell you why ;-).

[invalid unparseable]

English usually doesn't steal grammar from other langages, just words.

To wit:

"Adjectives in English absolutely have to be in this order: opinion-size-age-shape-colour-origin-material-purpose Noun. So you can have a lovely little old rectangular green French silver whittling knife. But if you mess with that word order in the slightest you'll sound like a maniac. It's an odd thing that every English speaker uses that list, but almost none of us could write it out."

It goes on to explain the rare exception to that rule, namely ordering vowel sounds in similar sounding words. Hence Little Red Riding Hood (size color purpose) fits, but Big Bad Wolf (size opinion) doesn't.
