When I was a freshman
The tube at the seniors hold so much through a drawing
Feel good, engineer style
Send out a textbook
Even if you are studying chemistry
Also have to learn this course called Engineering Graphics
You


Vernier caliper, T-square, triangle
Compasses, 2B, pencils and erasers are all necessary
You

Drawings are the language that engineers express themselves
The workshop shall be laid down and processed with the drawing as the standard
Now the engineers are already CAD drawings
So here comes the question...：
Once upon a time without these software,
How is the design drawn?
@ building: [Yi year, Pinghua] not eventful years thick computer era, to the layout of the city, a small brick to ” ”, is a pen strokes out of the mirror, mainly by drawing the translucent blue &rdquo, ” extension; and creative experience and drawing skills of &rdquo & rdquo; all meals cost; the most waste is not only the eyes, neck and sleeves is the greatest harm place. It's hard to change the drawing because it means that the whole drawing might be made up of a small white picture.
Count: @F school, a teacher who told us before your judgement is not an architect, you have to look at the stomach have a son … …
@Alex_Lau15: If today's Party A goes back to the hand-painted era, he will either die or die.
Do you remember the drawing room of your school?
You

This way?

This way?

Or tall on this?
(anyway, seven school is the first on the drawing board, wood graffiti occupies the brim)
Every time I have to memorize all kinds of tools to draw lessons in drawing room
The classroom is all big desk drawing students
It's spectacular!
Because everyone is unskilled
Night often burn the midnight oil
You

Of course, during the day, brighter children were pasted directly on the windows and painted
You

Please help yourself. Please note that this method is only for sunny days!
See at the Design Institute
Some older engineers still draw on the drawing board
Imperceptibly
The drawing method began to open a new leaf
You

That era
What are the design drawing rooms of the major design institutes?
Studio at that time








So many years have passed
The drawing board is already out of technical Cory
The square was missing
The vernier caliper has been changed into electronic digital display
Micrometer, angle ruler and other measuring tools have become the strict symbol of our mechanical 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 was interference, simulation...
Do you remember the scene of unit drawings when you worked?
------------------------
Thanks to my university, an engineering drawing class
Let our generation also experience an old project, drawing on the drawing board.
