Yang Fan first introduced cad while performing some simple operations, and then gradually deepened to introduce its functions in detail, with some slightly more complicated operations.

Although it is basically the first time we are exposed to computer-aided drawing, we can basically understand the unexpected discovery.

Why is this happening?

The reason is very simple. Yang Fan’s explanation is easy to understand and easy to understand. It only took more than an hour to finish it. Everyone felt that they gained a lot.

After Yang Fan finished speaking, Gu Zhengxin was the first to take the lead in applauding.

He stood up and clapped hard. After the applause gradually stopped, he said in great admiration: "Chief Yang, I didn't expect that you have such a deep research on computer-aided drawing. We have opened our eyes. I have already thought about it. After I go back, I will deploy this work immediately. Our process technicians will also use cad drawing and no longer use this purely hand-made drawing."

It's too time-consuming!

Now, Gu Zhengxin has no idea about it.

Yang Fan turned off the computer and suggested: "At this time, our designers have all gone to work. I'll take you to take a walk and take a look."

Of course this is good!

Gu Zhengxin almost agreed with both hands.

In the morning, they walked into the power system design room. It was already 11:30 in the morning. They got off work without long watching. They were not satisfied at all. I guess they didn't see many things.

"Chief Yang, then let's go now."

Yang Fan turned off the computer and took everyone to visit the design rooms. First, he went to the power system design room, and then went to several design rooms such as weapon systems, ship and electricity systems, combat systems, etc.

Every time I walked into a large office, the people at Hongqi Factory found that they were all computers, each designer was carefully drawing the design drawings of the 054 ship in front of the computer.

After watching this, I finally walked into the overall design room.

The situation in the large office here is similar, with computers placed on them, and everyone is drawing design drawings. Sometimes, people from Hongqi Factory will stand beside them and watch the designers draw design drawings, and occasionally ask questions.

The designers knew that these people were the guests of Chief Manager Yang, and they said everything. They answered them seriously every time, and the people from Hongqi Factory knew more.

They had already decided in their mood. After they went back, they would definitely recommend that the factory leaders buy computers and install cad drawing software. The process technicians in the factory all use computer-assisted drawing.

Gu Zhengxin looked at several designers in the overall design room drawing design drawings, especially the appearance design drawings of the 054 ship.

Although he knew that the appearance design of the 054 ship broke the conventional and was no longer a traditional appearance design, he couldn't help but ask when he saw such a design with his own eyes.

"Chief Teacher Yang, this is the radar stealth design of the 054 ship."

"Yes, this is both a radar stealth design." Yang Fan said: "The stealth design of the 054 ship includes radar stealth, sonar stealth and infrared stealth. Radar stealth is one of the major stealth designs."

A deputy director of the workshop technical department of Hongqi Factory was obviously curious and asked: "Chief Yang, let's introduce these stealth designs to us."

They are diesel engines. Although they are also military-industrial units, they only know a little about ship design at most. They know less about the very fashionable stealth designs nowadays, and they also want to know more.

Faced with such a request, Yang Fan simply gave them simple popular science.

There are three aspects of the stealth of the 054 ship: sonar stealth, infrared stealth and radar stealth. In layman's words, sonar stealth means to make the various sounds emitted by the ship as small as possible, and infrared stealth means to make the ship's heat source as hidden as possible. To deal with radar stealth, the appearance of the ship must be changed.

Radars rely on echo to detect objects. If the surface of the warship's hull has a peculiar geometric section, it can reflect the emitted radar waves to other directions, making the enemy's radar unable to obtain echoes, thereby avoiding the enemy's reconnaissance. Although it is impossible for the ship to be completely invisible, it can make the enemy discover it late and win time for taking action before the enemy...

The people from the Hongqi Factory listened enthusiastically.

The technicians in the overall design room also calmed down, most of them stopped drawing, and listened to Chief Professor Yang to talk about the principle of radar stealth.

Although as a ship designer, they know very well, have a professional knowledge and solid knowledge about stealth, it seems like a good thing to listen to Chief Professor Yang’s lecture.

After listening, Gu Zhengxin first gave a thumbs up and said, "Excellent, with such an advanced design, our 054 ship must be world-class."

Yang Fan said confidently: "It should be able to be among the world's top ranks. Compared with our 052 ship, it has indeed made a big step forward."

"Of course, the design of the 052 ship is also good, completely modular and platform-oriented. Although it is not yet at the world-class level, I think that in a few years, at most no more than ten years. After continuous improvement and upgrade, it will definitely be able to reach the world-class level."

World-class level!

The people from Hongqi Factory were secretly shocked!

The designers of the overall design room are full of pride!

Their work is extremely glorious now. The most advanced missile frigates in China are also first-class missile frigates in the international market. They are designing them.

So awesome!

It's really amazing!

Gu Zhengxin and others looked at the young Yang Fan with secret admiration.

After introducing the stealth design of the 054 ship and watching the drawing operations of many designers, Gu Zhengxin's eyes were attracted by a large printer placed in a corner of the large office.

It is printing the drawings.

Their Hongqi Factory generally does not print drawings, but technology technicians draw the drawings, and then the tracing officers draw the drawings on translucent cellophane, and then dry them into blueprints in the sun drying room.

The print should be a No. 1 drawing.

The printing of such a large drawing quickly attracted him, so he couldn't help but walk over and looked at the drawing after it was printed out, and looked at it with great enthusiasm.

The designer who printed the drawings also spread the large drawing on the big table, including Gu Zhengxin, and the people from Hongqi Factory could see clearly.

"Wow, what a beautiful design drawing."

"You see those words, you should be printing them. Even if you are a master with a high level, you probably won't be able to write such neat imitation Song characters."

"You look at the lines, and the layers are clear!"

“……”

The people from Hongqi Factory watched this large design drawing, as if they were observing an art treasure. Seeing them like this, Yang Fan smiled and said, "Don't be envious. After you use the Cad drawing, you will be the same as this."

Yes!

We will also use cad to draw in the future.

Wouldn't that mean that the drawings we draw are also very beautiful, and the process regulations we compile are also very beautiful.

...........

Gu Zhengxin and others only stayed in Donghai City for one night.

The next afternoon, they took a plane and hurried back to Hongqi Factory. On the night when they returned to the factory, Hongqi Factory held an office meeting.

Yuan Hui rarely attended the office meeting. By level, he could only be regarded as the middle-level manager of Hongqi Factory and generally could not attend.

But the topic of this office meeting was whether Hongqi Factory vigorously promoted computer-aided drawing. Yuan Hui not only attended the meeting, but also made a speech.

Gu Zhengxin and Yuan Hui both talked about the situation they saw in Donghai City, and also expressed some of their thoughts and suggestions.

Computer-aided drawing efficiency is so high!

The quality of the drawing is so good!

The senior executives of Hongqi Factory felt a little incredible, but they knew that Gu Zhengxin and Yuan Hui would not tell lies.

After talking about everything I saw in Donghai, Gu Zhengxin said: "Everyone, Donghai Institute has fully used computer-aided drawing. With such a large design task, they are sure to complete the comprehensive design in about two and a half years."

"Although the preparation of our process regulations is also very laborious, compared with the design task volume of the 054 ship, it is simply a slight witch. I am sure that if our factory also vigorously promotes computer-aided drawing, it may be possible to complete all process regulations in three or four months."

It only takes three or four months!

This is of great appeal to the senior management of Hongqi Factory!

I originally thought it might take a year, and even if it doesn’t take a year, nine or ten months should be needed.

What about now?

Gu Zhengxin said it only takes three or four months.

You heard it right!

A deputy general manager asked, "Old Gu, it really takes only three or four months to complete all process regulations."

"Yes, I'm sure I'll finish it." Gu Zhengxin answered affirmatively.

If he had not gone to Donghai Institute and completed all the process regulations in three or four months, he felt that this was a day-to-day talk, but now he felt that it was completely possible.

With such a positive answer, the other people's hearts started to move.

Another deputy general manager said: "Since computer drawing is so efficient, I suggest vigorously promoting it."

As soon as the voice fell, I agreed: "I also agree with the promotion of computer-aided drawing."

Almost most people agree, but some people reminded: "Computer-assisted drawing is good and efficient, but first you have to buy a batch of computers, which costs a lot of money!"

money!

A lot of money!

This is exactly what Hongqi Factory lacks.

With the reduction of the amount of tasks, they have only paid basic living expenses for several months. At this moment, they have taken at least hundreds of thousands of yuan to buy computers, printers, etc., and the pressure is undoubtedly great.

yes!

Want money!

Everyone's eyes couldn't help but look at the top leader Zhu Chuandong.

Gu Zhengxin also looked at Zhu Chuandong.

However, his eyes were different from others, full of worry, with a hint of nervousness, and he was very afraid that Zhu Chuandong would shake his head and deny it.

What if it is really denied?
