When will I have a long tassel?

"Hey, where is the teacher Xiao that Lao Sun mentioned?"

"Isn't that the girl on the podium? Old Sun was pointing at her just now."

"How is this possible! Didn't you listen to Lao Sun's introduction that the teacher's name is Xiao Wenjun? He is obviously a man. How can there be a woman teaching computers?"

"What's wrong with women? Women are worse than you?"

"That's not what I meant. I said yes. This girl is too young. How can she be a teacher at Tsinghua University?"

"Maybe lesbians in big cities can take care of themselves..."

Everyone was talking about it, but few believed that Xiao Wenjun was the training teacher Sun Min said. Among them, Xiao Wenjun's age is a flaw, and people's stereotype of "IT elites" also plays a role. In fact, Tang Zifeng had never had such an idea before. He always felt that a person who could be a computer teacher should be a man anyway, and he should be a man with less hair...Don't ask him how he knew.

"You..." How could Sun Min not know what his subordinates were thinking? He himself had made a mistake before, so it was inconvenient to accuse his subordinates of being ignorant at this time. But Xiao Wenjun just stood there, and everyone turned a blind eye. This was too disrespectful to others. He gave Xiao Wenjun an apologetic look, and then he was ready to yell at everyone.

Xiao Wenjun stopped Sun Min who was about to speak. She smiled at Sun Min and said, "Director Sun, don't worry. People may think that I am young and a little distrustful. This is normal. Let me tell you first. Demonstrate the CAD drawing process and I believe everyone’s ideas will change.”

"Okay, okay, then please ask Teacher Xiao to demonstrate it to everyone first." Sun Min said repeatedly.

He knew what Xiao Wenjun meant, which was to show everyone his skills and calm them down. Facts speak louder than words. No matter how much you introduce your identity, it is better to show some real skills. This is an unchanging truth. Besides, Sun Min himself didn't have enough confidence in Xiao Wenjun. He also wanted to see if this young girl was qualified for the job.

Wang Junti, who was responsible for debugging the system, stepped forward and turned on the computer on the podium, turned on the projector, and projected the display on the computer onto the large curtain hanging on the podium.

This time, in order to support Lin Yiji’s board-breaking work, the second round was considered a huge investment. In addition to the 50 computers donated by Lenovo Group, the Second Bureau also allocated a number of computer room peripherals to Linyi Machine from other places, the most expensive of which are two A0 format inkjet plotters and a projector. Nowadays, the price of an HPDJ600 plotter is 50,000 yuan, and the price of a 3M projector is as high as 80,000 yuan.

Initially, Xie Tiancheng was not prepared to equip Linyi with a projector, which was considered a luxury item even for central ministries. But he couldn't stand Tang Zifeng complaining in front of him, saying that he had to complete the CAD training in such a short period of time. Without a projector, he couldn't do it at all. He couldn't let the teacher guide him machine by machine, right? The purpose of Linyi Machinery's drawing board was to complete Xizhong's re-boring design, which in turn was related to Linyi Machinery's plan to get out of trouble. Director Zhou and his little Tang were eating chaffy vegetables, lighting lamps and boiling oil in Linlin, just to fulfill the great trust of the bureau leaders. Are the bureau leaders reluctant to part with this mere piece of equipment worth tens of thousands of dollars?

Xie Tiancheng was somewhat apologetic about sending Zhou Heng and Tang Zifeng to take a chance. After hearing what Tang Zifeng said so miserably, he finally gritted his teeth and instructed the Finance Department to use a special fund. , helped Lin Yiji buy this expensive projector.

When everyone saw the projector turned on, and saw the young girl who had been ignored by everyone walking to the computer on the podium, they all became quiet, waiting to see Xiao Wenjun's operation. They vaguely realized that this young girl might really be the training teacher introduced by Sun Min. As for whether she was qualified, it would depend on her operation.

In fact, this is not the first time that Xiao Wenjun has gone out for CAD training. Previously, Tuao Company had also invited teachers from the mechanical department to provide training to their customers. Xiao Wenjun initially went there as the teacher's assistant, and later had the opportunity to teach independently. She knows that her gender and age are flaws, and it is normal for others to doubt her abilities.

However, when she was doing training in the capital, the training subjects' contempt for her would not be so strong, let alone so obvious. As a long-established heavy industry company located in a third-tier city, Linyi Machinery's employees' attitudes are indeed more outdated. It is normal to look down on women and young people.

Xiao Wenjun saw everyone's clamor just now and was already holding his breath. She sat down in front of the computer on the podium, typed a few commands, found the directory where CAD was located, started the program, and then waved the mouse to start drawing a part.

Everyone stopped talking and stared at the curtain on the podium, watching how Xiao Wenjun typed out lines of commands on the keyboard, used the mouse to bring up windows one by one, and performed various dazzling operations. In order to completely suppress these uncles and aunts who tried to look down on him, Xiao Wenjun also used all his skills, and his hand speed was so fast that Tang Zifeng, who had been tempered in online games, was in awe. In the end, the refresh speed of the projector could no longer keep up with Xiao Wenjun's operation speed. When the mouse passed over, afterimages were left on the screen.

"A cylinder..."

"The arc is drawn out. Oh my god, it's so convenient..."

"Does this require opening holes? Once you design one hole, you can stick it to other places. Six holes only need to be drawn once. This saves so much trouble!"

"Look, it's now two pictures. Is this the left view?"

"Come on, come on, there's a bird's-eye view too, my sun, this is so easy!"

"Damn it, I've been drawing pictures all my life, it's just a waste of time!"

"Stop talking, do you know how to do this?"

"Isn't there a teacher?"

"I'm convinced. This girl looks younger than my daughter. How to play with this computer... Oh, there's really no comparison between people!"

"Unfortunately, I just thought she must be here to carry the teacher's bag. It really blinded me..."

Everyone was just whispering at first, but gradually the voices became louder and the mood became more and more exciting. Everyone felt as if a new window had been opened in front of them, and the bright sunshine was shining, making people's blood surging.

As engineers, of course everyone has heard about CAD drawing, especially several engineers from the Electrical Technology Department. They have installed CAD systems on computers and tried drawing. But I don’t know whether it’s because of their specialization in the art or the lack of guidance from famous teachers. The pictures they drew are ugly, and the operation is stumbling. They can’t find the pleasure of computer drawing at all. They feel that they are not as good as themselves with this skill. Take a duckbill pen and draw casually.

But now when they saw Xiao Wenjun's operation, everyone knelt down. It turns out that drawing a picture is so easy, and it turns out that there are so many skills in drawing. Just type in the coordinates and you can locate it accurately. In the past, you needed to hold a triangle and make gestures for a long time. Just enter any parameter, and the height, shortness, fatness, and thickness of the parts can be changed quickly. In the past, if you made a mistake, you could only tear it up and start over. There is no such easy way to modify it.

There are also standard parts graphics preset in various systems. You only need to call them up and change a few numbers, and you can use them directly. Doesn’t this mean that even fools can design? Hey, is this thing a calculator? How can I still write formulas into it? This is calculating the bisecting points of a circle. A few commands, all done, wait, what kind of monster is this girl? She can remember formulas like this. Ripe...

At this moment, no one dared to have any contempt for Xiao Wenjun. Not to mention that the software is easy to play, and the design is also expert. No one can understand what the parts she is drawing are, but everyone can understand the design principles. It is very consistent with the conventional design principles, and there are basically no flaws.

Part design is not just about drawing two circles, but must take into account requirements such as load, cross-section, wear resistance, processing technology, etc. Parts that also meet the same function are designed by experienced engineers to save materials to the greatest extent, reduce processing hours, and ensure durability. And if it were a newbie who was just starting out, there wouldn't be many monsters coming out.

Everyone present is an experienced driver..., well, it should be said that they are experienced engineers. You can judge whether the design of a part is reasonable or not at a glance. This little girl in front of me has only had her driver's license for a few years? The designed drawings can actually be so sophisticated. Could it be that she memorized a ready-made drawing and wrote it down for everyone here? Even so, at least his memory is off the charts.

"alright!"

Xiao Wenjun finished the entire drawing, and under the guidance of Wang Junti, sent the drawing to the printer to print thumbnails. Not to mention the slow speed of A0-format inkjet printers, the printing costs are also staggering. Xiao Wenjun is just giving a demonstration, so there is no need to use this artifact.

"Wow!"

Without waiting for Sun Min's call, everyone spontaneously applauded. The applause was louder than the one given to Tang Zifeng just now, and it lasted for a long time. There was some excitement on all the people's faces, including the excitement after watching a wonderful performance and the longing to master CAD technology in the future. If everyone was still a little skeptical about the idea of ​​dumping boards before, now everyone has become a loyal supporter of the work of dumping boards. After seeing how to use CAD to draw, everyone felt that drawing with a duckbill pen one stroke at a time was simply irresponsible for life.

"Not bad, girl, you didn't embarrass your father."

Qin Zhongnian walked to Xiao Wenjun, his old face smiling like a daisy. He patted Xiao Wenjun on the shoulder and sighed.

"Uncle Qin, thank you." Xiao Wenjun stood up and said modestly. Before Qin Zhongnian could react, she added: "However, I taught my dad how to use CAD drawing."

"Uh..." Qin Zhongnian choked so much that it took him a long time to say something indifferently: "Sure enough, the young are better than the old. Our generation is old, and the future world belongs to you."

Just to say a few words, you don’t need to check which province is which province or which factory is which factory. First of all, this is made up by Cheng Zi. Secondly, if you really prove it, this book will be 404. Things like mapping are the most dangerous. Just read the book and vote. The more you vote, the better. This book is already a high-quality product, and its results are better than those of Great Power Heavy Industries in the same period. Except for the lack of monthly tickets...
