"Hey, where is Mr. Xiao that Lao Sun said?"

"Isn't that girl on the podium, just now Lao Sun pointed at her. ”

"How is this possible? You didn't listen to Lao Sun's introduction, saying that the teacher's name is Xiao Wenjun, and he is obviously a man, how can there be a woman who teaches computers. ”

"What's wrong with the woman, the woman is worse than you"

"I didn't mean that, I said yes, this girl is too young, how can she be a teacher at Tsinghua University. ”

"Maybe lesbians in big cities will take care of ......"

Everyone talked about it, but few people believed that Xiao Wenjun was the training teacher Sun Min said. Among them, Xiao Wenjun's age is a hard injury, and people's stereotype of "IT elite" also plays a certain role. In fact, Tang Zifeng didn't have such an idea before, he always felt that a person who could be a computer teacher should be a man no matter what, and it should be the kind of man with little hair,...... Don't ask him how he knows.

"You ......" How could Sun Min not know what his subordinates were thinking, he himself had also set up an oolong before, so it was inconvenient to accuse his subordinates of being blind at this time. But Xiao Wenjun was standing there, and everyone turned a blind eye, which was too shameless for people. He gave Xiao Wenjun an apologetic look, and then he was ready to send a blow to everyone.

Xiao Wenjun stopped Sun Min, who was about to speak, she smiled at Sun Min and said, "Director Sun, don't worry, everyone may think that I am young and a little distrustful, which is also normal." In this way, I will first show you the process of CAD drawing, and I believe that everyone's thinking will change. ”

"It's okay, it's okay, then please ask Mr. Xiao to show you first. Sun Min said repeatedly.

He knew what Xiao Wenjun meant, that was to show everyone a hand and calm everyone. Facts speak louder than words, and no matter how much your identity is introduced, it is better to show some real kung fu in your hands, which is a long-lasting truth. Besides, Sun Min himself does not have enough confidence in Xiao Wenjun, and he also wants to see if this young girl can do this job.

Wang Junyi, who was in charge of debugging the system, stepped forward to turn on the computer on the podium, connected the projector, and put the display on the computer on the large curtain hanging on the podium.

This time, in order to support the work of the throwing board of the first machine, the second game can be regarded as a bloody investment. In addition to the 50 computers donated by Lenovo Group, the Second Bureau also allocated a number of computer room peripherals to Linyi from other places, the most expensive of which are two A0 format inkjet plotters and a projector. At present, the price of an HPDJ600 plotter is 50,000 yuan, and the price of a 3M projector is as high as 80,000 yuan.

Originally, Xie Tiancheng was not going to equip Linyi with a projector, which was considered a luxury even for the central ministries and commissions. But he couldn't stand Tang Zifeng complaining in front of him, saying that to complete the CAD training in such a short time, there is no projector at all, and he can't let the teacher guide the machine by machine, the purpose of throwing the drawing board is to complete the heavy boring design of Xizhong, and this is related to the plan of the Linyi machine to get out of trouble. Director Zhou and his Xiao Tang were eating bran and cooking vegetables at Linyi, lighting lamps and boiling oil, just to complete the trust of the bureau leaders, and the bureau leaders were reluctant to even have tens of thousands of yuan of equipment

Xie Tiancheng was somewhat apologetic about sending Zhou Heng and Tang Zifeng to Linyiji, listening to Tang Zifeng say it so badly, he finally gritted his teeth and heart, and instructed the Finance Department to use a special amount of money to help Linyi buy this expensive projector.

Everyone saw that the projector was turned on, and saw that the young girl who was ignored by everyone just now walked to the computer on the podium, and quieted down, waiting to see Xiao Wenjun's operation. They vaguely realized that this young girl might really be the training teacher introduced by Sun Min, and as for whether she was qualified enough, it would be up to them to see what she did.

In fact, it is not the first time that Xiao Wenjun has gone out to do CAD training. Previously, Tuo had also invited teachers from the Department of Mechanical Engineering to train their customers, and Xiao Wenjun first went as a teacher's assistant, and later had the opportunity to teach independently. She knows that her gender and age are hard injuries, and it is normal for others to doubt her abilities.

However, when she was training in the capital, the contempt of the trainees for her would not be so strong, let alone so obvious. As an old heavy industry enterprise and located in a third-tier city, the concept of employees is indeed more outdated, and it is normal to look down on women and young people.

Everyone's uproar just now, Xiao Wenjun saw it in his eyes, and he already held his breath. She sat down in front of the computer on the podium, typed a few commands, found the directory where the CAD was located, launched the program, and then waved the mouse and began to draw a part.

Everyone stopped squeaking, staring at the curtain on the podium, watching how Xiao Wenjun used the keyboard to type out lines of commands, used the mouse to call up windows one by one, and did all kinds of dazzling operations. In order to completely suppress these uncles and aunts who tried to underestimate themselves, Xiao Wenjun also used all his skills, and his hand speed was so fast that Tang Zifeng, who had been tempered thousands of times in online games, sighed to himself. In the end, the refresh speed of the projector could no longer keep up with Xiao Wenjun's operation speed, and when the mouse flicked, what was left on the screen was a series of afterimages.

"A Cylindrical ......"

"Pull out the arc, oh my God, it's so convenient......"

"Is this to open a hole, design a hole, you can paste it to other places, six holes, you only need to draw once, how much work you have to save!"

"Look, it's two figures, this is the left view"

"It's coming, it's coming, the top view is also there, my sun's, it's too convenient!"

"Damn, Lao Tzu has drawn a picture for a lifetime, and it's a waste of time to meow!"

"Don't talk nonsense, will you do this?"

"Isn't there a teacher?"

"Convinced, this girl looks younger than my daughter, and this computer is ...... Alas, there is no comparison between man and man!"

"I thought she must have come to carry the teacher's bag just now, it's really blind to my dog's eyes......"

At first, everyone was just whispering, but slowly their voices became louder and more emotional. Everyone felt as if a new window had opened in front of them, and the bright sunlight was shining brightly, making people's blood surge.

As an engineer, of course, everyone has heard about CAD drawing, especially several engineers in the electrical technology department, who have also installed CAD systems on their computers in the past and tried to make drawings. But I don't know if it's because of the specialization in the art industry, or the lack of guidance from famous teachers, the pictures they draw are ugly, not to mention, the operation is also stumbling, and I can't find the refreshing feeling of computer drawing, and I feel that it is better to draw casually with a duckbill pen with this work.

But now when I look at Xiao Wenjun's operation, everyone kneels. It turns out that it is so easy to draw a picture, and it turns out that there are so many skills in drawing. Just knock on a coordinate, you can accurately position, and this used to be a half-day comparison with a triangle board. Just enter a parameter, the height of the parts can change quickly, change to the past, draw the wrong can only be torn off and restarted, how can there be such an easy way to modify.

There are also preset standard part graphics in various systems, as long as you call it out and change a few numbers, you can use it directly, which doesn't mean that fools can also do design. Hey, is this game a calculator?,How can you still write a formula into it?,It's calculating the equinoxes of the circumference.,A few commands.,Handle them all.,Wait.,What kind of demon is this girl?,Can you remember the formula so well......

At this moment, how dare everyone have a trace of contempt for Xiao Wenjun in their hearts. Don't talk about other people's software, but it's also an expert in design. The parts she is drawing now, you can't understand what it is, but the design principle can be understood by everyone, which is very in line with the conventional design principle, and basically can't find any flaws.

The design of parts is not just about drawing two circles, but about taking into account the requirements such as load, cross-section, wear resistance, processing process, etc. The parts that also meet a function, designed by experienced engineers, can save materials to the greatest extent, reduce processing man-hours, and ensure durability. And if you change to a fledgling rookie, you may not have to produce many demon moths.

All of you present are veteran drivers...... Uh, I should say that I am an old engineer, and I can judge at a glance whether the design of a part is reasonable or not. The little girl in front of her, who has only been designing the drawings for a few years with her driver's license, can be so sophisticated. Could it be that she memorized a ready-made drawing, and wrote it down for everyone here silently, even if this is the case, at least people's memory is also explosive.

"That's it!"

Xiao Wenjun finished drawing the whole picture, and under the guidance of Wang Junyi, he sent the graphics to the printer to print the thumbnails. A0 format inkjet printer is slow and not to mention, the printing cost is also staggering, Xiao Wenjun is just giving you a demonstration, there is no need to move this artifact.

"Wow!"

Without waiting for Sun Min's call, everyone spontaneously applauded, which was a little louder than the applause given to Tang Zifeng just now, and it lasted for a long time. There was some excitement on everyone's faces, ranging from the excitement of watching a great show to the hope of mastering CAD technology in the future. If everyone was a little skeptical about the flipping board before, now all of them have become loyal fans of the flipping board. After seeing how to use CAD to draw, everyone feels that it is irresponsible to draw stroke by stroke with a duckbill pen.

"Yes, yes, girl, I didn't embarrass your father. ”

Qin Zhongnian walked to Xiao Wenjun's side, and his old face smiled like a daisy. He patted Xiao Wenjun on the shoulder and let out an exclamation.

"Uncle Qin has won the prize. Xiao Wenjun stood up and said modestly. Without waiting for Qin Zhongnian to react, she added another sentence: "However, my father uses CAD to make drawings, and I taught him." ”

"Uh......" Qin Zhongnian was choked enough, and it took a long time before he said a sentence: "Sure enough, the blue is better than the blue." Our generation is old, and the world of the future is yours. ”
