Cartography is an engineer's language,
Factory design, material production and so on
Now the post-80s and post-90s engineers are CAD drawings
Before computers became ubiquitous
Engineers are hand-drawn drawings
The tools used are vernier calipers, t-feet, triangular plates, compasses, 2B pencils and eraser.
The drawings are finished on the drawing board
The drawings used are drawing No. 0 and drawing No. 1...
Drawing on large paper is very hard
The thick drawings killed us too much day and night
The bitter and the sweet, only those who experience it are engraved on their hearts
Different from now
That will have a special drawing room when you go to school
Remember Xiao Bian's going to school
Each drawing has many tasks
The classroom is all big desk drawing students
Spectacular
Because everyone is unskilled
Night often burn the midnight oil
He has a computer after work
The young people in the unit studied CAD and CAXA
The older engineers still draw on the drawing board
Maybe from where?
The drawing method began to open a new leaf
What was the design drawing room of the major machinery manufacturing companies and design institutes at that time?
Walk into the studio without CAD
↓ ↓
Many years have passed,
The drawing board is already out of technical Cory,
The square was missing,
Only vernier calipers became electronic digital display,
Micrometer, angle ruler and other measuring tools have become the strict symbol of our engineers,
Drawing also entered the computer from the drawing board,
From the display of plane space to the display of three-dimensional space,
Then there's the 3D simulation...
Do you remember the scene of unit drawings when you worked?
That's impermanence: not only to desk with a pencil and ruler carefully painted each line, arc and circle, and after painting, there are special tracers in tracing paper re inking a piece, and then use this as a base to start tracing Slide Show, is used the sun Slide Show, again on the map in the bucket with ammonia smoked smoked out, due to smoke out the color is blue, known as the blueprint, so later with a grand blueprint to describe major planning and design. In the future there are some large units will use the sun Slide Show Slide Show machine and smoked graph in this one machine, improve the efficiency of. But the drawing room is always full of ammonia.
Dream too tempting: Although I was 90, is now working with the CAD drawing, but when the university regulations are we drawing sketch, we also experienced the kind of life, hand really can train a person's drawing ability, to deepen the understanding of the structure. The regulations in our school are really good. Love us, University of science and engineering.
Mr. no problem: me, me, me!!! Our school has been retained by hand drawing, although there are a lot of students do not understand why can also draw by hand painting with computer, but I still love hand-painted, is tired of PS on the semester just finished two reducer, are of their own design!
Big jujube: I am 99 years high school graduation 19 years into the factory lathe apprentice. With the master to help Slide Show during the Slide Show room. Translucent papers draw very rules of appearance, character description one. In order to prevent the use of sewing machine sewing processing broken around. The ammonia tastes so strong. In the twinkling of an eye, CAD times. Unfortunately, now the new employees CAD painting is a mess, the description is not clear.
Enlightened: spectacular! The pictures are great. See all, only to find, women rarely. That although women generally cautious, but logical thinking is indeed better than men. You'll have to draw the blueprint after the painting, won't you? The blueprint also comes from the design studio.
Li Ning: the hard work of drawing on paper is one thing. More can not imagine that, in the absence of 3D CAD software, mechanical engineers can rely on powerful imagination space to design a large-scale machinery complete, all parts and components through the design, processing, assembly, and does not produce anyInterference, that's where the cow is! Former mechanical engineers must have built blocks in their heads. When they were designed, they would take a look in the mind and see the interference! It must be so! Ha ha ha
Thorn bird: time in drawing too much cost, also let many engineers forget yourself is an engineer is a designer, and put himself into a draftsman; forget the design thought is the soul of engineering and design, and the entanglement in the paper forms a line &hellip & hellip;
Lin Zeqiu: I was lying on the board with T-square, triangle, compasses and countless strokes Yazui drawings, retired learned CAD computer graphics makes me excited, so I did do a few years back in the past, with emotion.
Calvin: my 10 years of college, learning CAD drawing or manual drawing, remember the teacher also fooled us to buy a T-square, said that this is a basic tool for drawing.. As a result, I bought the item without using it. I have been working on it. Who else can use it?
Zhou Shousheng: hand drawing lessons, just learning some alignment with the three view, very simple things; now see drawing standard in hand-painted version of predecessor units, technical specifications are small font ligatures, with print not what two things, see the specification really shocking to me, on the mechanical drawing so serious!
