Engineering drawing I rule you

After learning CAD, Xie Huai's nightmare really began.He failed the computer-based test last year, but now he is upset when he sees the drawing software.Although I want to finish my homework and hand it in as soon as possible, I have been unable to concentrate, and I can't control the urge to swipe my phone after a few strokes.

What's more terrible is that last week there was an idiot in the school who smoked and set the dormitory on fire, which caused the sensitivity of the smoke alarms in the whole school to increase, and even the plastic wrap didn't work.

In order to relieve the depression in his heart, he could only go to the smoking booth at the entrance of the cafeteria to draw pictures while smoking in the snow at night.

As a result, my hands froze before I finished smoking, and my brain convulsed. I didn't know what I touched by mistake, and the menu bar of CAD was hidden.

In desperation, he could only send a message to Qin Yiyan for help.Fortunately, the other party happened to be free, and soon sent a presentation to teach him how to debug the software.

Xie Huai suddenly regained his new life, thinking that he should have the habit of summarizing knowledge points when studying, and asked cheekily: Senior, how many precious butt kicks do you have in your hand, can you give them all to me!

[Ass kick? ] Qin Yiyan asked in puzzlement.

Only then did he realize that he was about to send the wrong message, and couldn't help complaining about this bullshit input method, which is really harmful.

[It means PPT, nothing else. ]

Qin Yiyan sent an oh, and a few minutes later left a message saying: I can't find it.Next time I come to the office, I will teach in person.

[That's great, thank you. ] Xie Huai repeatedly thanked him, and quickly debugged the menu bar to continue drawing, but he didn't realize what was wrong.

At the end of the short conversation, Qin Yiyan stared at the word "butt kick" for a long time, then thoughtfully opened Moments.

It was the first time he was interested in other people's daily life.

Unexpectedly, the latest news was half an hour ago.

December 2021, 12 "Study Diary"

Once upon a time, there was a little boy who was studying engineering drawing. He would hold a CAD and shout at the side of the road: "Let's draw the next one first. An exercise book cannot be full of problems." But he flipped through several pages one after another. Graphics are getting more and more complex.The little boy painted in the snow for three days and three nights. He was cold and hungry that day, so he took out the only uranium 235 left in his pocket and ignited a nuclear bomb.Through the crackling flames, he saw Liang Sicheng and Lin Huiyin waving to him, and after a few seconds, everyone in the school saw Big Ivan.

There are two accompanying pictures below, which are the heavy snow outside the glass window and the lit cigarette in the hand.

A tearful indictment.

This is probably the pain that good students will never experience.

Qin Yiyan looked at the heavy snow fluttering outside the window with great interest, put on his coat and walked out of the office.

According to the angle at which the picture was taken, he guessed that Xie Huai was squatting miserably in a smoking room drawing pictures.When I walked to the Civil Engineering College, I found a listless little guy chewing on a cigarette butt in the glass pavilion outside the cafeteria.

He opened the door and entered.Accompanied by a gust of cold wind, Xie Huai raised his head subconsciously and asked in surprise, "Why are you here?"

"I saw the circle of friends you posted." He took out a piece of warm baby and put it on the table without even hiding it. "Is it not cold to draw pictures in this kind of place?"

The smoking booths are designed to be airtight and have no heating.The air-conditioning keeps circulating in the room, enough to make people numb from the cold.

At this moment, there was a can of coffee and a pack of cigarettes in front of Xie Huai's desk, like a homeless stray cat, burning the lamp to study at night in the bitter wind and rain.

Seeing Nuan Baobao, he quickly tore open the package, held it in his palm and rubbed it repeatedly, and complained: "There is no way, smoking is completely prohibited in the room now."

"You can't use smoking as a way to relieve tension and anxiety." Qin Yiyan pointed out the problem seriously, "At least you can't smoke in the examination room."

"..." Xie Huai was speechless, pulled up the scarf and buried half of his face in the soft wool.

Qin Yiyan took a few steps forward, saw the messy lines on the computer screen, and quickly realized the problem, prompting: "A straight line passing through the tangent point and perpendicular to the tangent line must pass through the center of the circle."

"What?" Xie Huai thought for a moment that he was reading from heaven.

Qin Yiyan sighed helplessly, opened the desktop browser, entered a string of big characters "How to draw tangent circles in CAD" on the home page, and dozens of pages of documents and videos popped up immediately.

He pointed to one of the highly praised answers and said calmly: "Use search engines well. Civil engineering has been developed for thousands of years, and the experience of predecessors is in front of your eyes."

Xie Huai was stunned again and had nothing to say, so he could only continue drawing with his face drooping.However, this software consumes a lot of power to run. There is no socket in the smoking booth, and the computer power is already running out.He could only draw two parallel lines hastily, and save the drawing first.

"The computer is out of power. I'll go back and draw again." He got up and packed his schoolbag, stretching his muscles lazily, "By the way, Mr. Zheng left a ticket for you, why don't you go back to the dormitory with me to get it?"

"What day of the week is the show?"

"Seven o'clock on weekends."

That's the end of the defense.Qin Yiyan turned on the phone and glanced at it, then nodded in acquiescence.

Seeing this, Xie Huai smiled happily at him, put on his schoolbag and walked out.It was colder outside than indoors, and heavy snow like goose feathers was falling densely, heralding the arrival of the next cold wave.

As a southerner, he was really afraid of the cold, so he hurriedly wrapped his scarf, put on his hat, and shivered beside Qin Yiyan.

"It would be great if someone could design a smoking room with good thermal insulation." After a long while, he couldn't help but sigh with emotion.

"Smoking is harmful to health, and society does not advocate it."

"Then it should be controlled from the source. It's really ridiculous to want to buy tobacco for high profits, and then hold up the banner and shout to quit smoking." The group is huge, isn’t architectural design serving the collective in need?”

Qin Yiyan seemed very interested in what he said, and asked, "Then what do you think?"

"For example, design a sponge wall to reduce the heat exchange with the outdoors?" Xie Huai doesn't understand HVAC, so he talks nonsense, "Then install induced draft fans in the wall, and realize indoor and outdoor air circulation through underground pipes."

"The idea is good, but this kind of wall has high requirements on the waterproof, thermal insulation and heat dissipation performance of the material, and it is difficult to achieve a comprehensive balance." Qin Yiyan pointed out the disadvantages almost without thinking, but fell into thinking halfway through the talk.

Isn't building materials exactly the field of research?

He shut his mouth in embarrassment.Fortunately, Xie Huai didn't realize this, the two quickly walked to the door of the dormitory, Xie Huai asked him to wait for him in the lobby on the first floor.

Within a few minutes, I saw him running downstairs holding the ticket for the closing ceremony of the art festival. Not only that, but he also had a plastic bag in his hand.

"These are little desserts that I think are delicious. Aren't you hypoglycemic? Put a few pieces in your bag at ordinary times, don't wrong yourself." Xie Huai stuffed the two items into his hands together, "Remember to come to the show. Zheng Jiajia arranged me in the C position, and I can see it at a glance when I sit below."

He couldn't help frowning slightly, but he couldn't think of words to refute, he hesitated for a moment and still accepted the things.

"Remember to eat seriously and be a happy cook!" Xie Huai made a victory gesture to him, and walked back happily, "Good night, go to bed early."

"Well, good night." Qin Yiyan said goodbye to him with the same words.

But he didn't go out in a hurry, but opened the plastic bag and looked at the snacks inside.There are toffee and snowflake crisps, as well as several bags of imported fruit candy, which seem to be expensive.

Qin Yiyan suddenly felt that Xie Huai still had a lot of advantages if he put aside his studies - he was willing to help others, good at observing, and had his own unique insights into things.

Although he can't agree with this innate personality, the occasional absurd jokes and carefully prepared gifts don't seem to be a bad thing.
