I think they called it "technical drawing"

Probably wouldn't be a course here anymore. Since the HBS is long gone (it's become the VWO I believe) the focus shifted. I'll ask my dad sometime about it. I've seen some of his engineering drawings, somehow he still has them. ;) He hated that course though.

@mur2501

@trinsec @freemo
Well the concepts in it are interesting and nice but it fucking takes hours to draw stuff and things get ruined with just one going a few degrees missing
Especially in the current condition of doing it in home with improper tools and environment.

@mur2501
Isn't a ruler just a ruler? What improper tools are we talking about?
But I agree, I wasn't really fond of all this precision drawing either. I'd rather use a computer for that, heh. At least you could ctrl-z nicely if you made a mistake!

Hell, life needs a CTRL-Z feature!

The roller rulers are intended to be a cheap replacement for a proper architect T-ruler or the wire fixed equivelant. A T-ruler only works on an architects table where a roller ruler you can use on any notebook anywhere.

The idea is that you can move the ruler up and down and the lines will remain parallel and fixed as long as you dont lift it. Then you can pule triangles or protractors on top of it to create various angles.

@mur2501

@freemo
Aaahhh, ok that's nicely explained. Dad and me use the hook-ruler regularly when DIYing up with planks.

I think I'd probably still use normal rulers instead of those rolling things. I fumble way too much.

@mur2501

@mur2501
Protractors and rulers I've used before (maths). But the 'Roll-n-draw' ruler I've not seen before and am not really sure how you'd use it heh.

@freemo

@trinsec @freemo
Roll-n-draw is used for drawing parallel lines though it is less accurate and cumbersome compared to drafters

@mur2501
I had to imagegoogle 'drafter', it seems to be a compass?

@freemo

@trinsec @freemo
This is a drafter

@mur2501 Huh, never worked with that one. It looks like you could draw summoning circles with it!

@freemo

@mur2501 @trinsec @freemo Never seen this. Just found videos on Youtube. Another Indian great mathematics thing that no-one know outside of India ? That's an interesting analogic vector tool that work both with Cartesian and polar coordinates.

@popolon @freemo @trinsec
Well it's not Indian, it's just called drafter in India while outside it is called drafting machine though you gonna find drafters/drafting machine all around the world with architects, engineers, etc (though ofcourse now we use computers to draw so this is old)

@popolon @freemo @trinsec
There are many tools used in technical drawing
Like this pantograph

@mur2501 @freemo @trinsec This one, I know, I was using it when I was young for fun drawing. There is spirograph too (several gears with different size, with hole to place pen).
that allow to do this kind of drawings:

@mur2501 @freemo @trinsec the tool is of that kind, there are a whole set of gears of different size to multiply the possible shapes combinations.

@popolon @freemo @trinsec
Well yes there are alot of tools in technical drawing which were used widely in the past when everything was drawn by hand, now you won't gonna find this tools anywhere apart from colleges

@mur2501 @freemo @trinsec I studied just a very little industrial drawing, for electronic purpose (but there was general mechanical objects drawing in course), and I never seen/used this. I want one, for the time where we don't have not enough oil or potatoes to power computers and continue to play with vectors drawing :)

@trinsec @freemo
Well the basic reason to prefer these fancy rulers is cause even a mistake of 1 cm or some degree angle can ruin the whole drawing and you will have to restart.

@mur2501
My dad used paper with a millimeter-grid on it, you don't have those?

And why don't you get a drafter?

@freemo

@trinsec @freemo
Milimeter grids are good but in technical drawing you also have to draw parallel lines to angled lines not just X and Y axis.

For using drafters you need a table or bench made for the purpose of technical drawing (our drawing papers are very big), so ofcourse people don't have those in their homes also drafters aren't sold in everywhere especially outside cities. As well as I only have to do technical drawing for just one semester which is gonna end on 20 August

@mur2501
Aha. Well, do your best and I wish you the very best of luck! The sooner you can get to actual computer science-related stuff, the better. :)

@freemo

@trinsec
Well this is Indian education it never gets better.
There are literally computer engineers here with degree who don't know how to actually code
Anyway I focus on real outside of curriculum activities so that's Why I am currently working on a research paper with the dean of my college

@freemo

@mur2501
Don't feel bad. There are people here who graduated in computer science who barely know how turn on a computer. A study is just for a piece of paper and lots of theory, the real knowledge and experience you have to get from the big world.
