It is to use computers to help designers carry out data calculation, information storage, drawing and other work. Through the special graphics processing software, the working drawings we need are designed, and in this process, the computer automatically generates graphics and data...... "Xie Kai understands CAD very clearly.

In China, in the field of machinery, technicians must master the auxiliary design software.

Few people continue to draw on the drawings, using the special auxiliary software of the computer, after the design of the product, the drawings can be printed directly.

Whether it is CAD for 2D or 3D design, or CAM software for auxiliary manufacturing, Xie Kai is very proficient, but he has no way to develop this kind of software by himself as he understands the CNC system.

Mechanical design software requires many functions, and at the same time, it also needs a huge database to support the operation of the entire software.

Domestic professional software in this area will not appear until the nineties, and it is not fully functional.

After the first computer graphics system was born in the United States in the fifties, the curved sheet technology of CAD appeared in the early sixties, and then the commercial computer drawing system was launched in the middle of the year...... It was not until the 80s that microprocessors and memories made of VLSI circuits appeared, microcomputers began to be popularized, engineering workstations began to appear, and CAD technology began to be popularized in small and medium-sized enterprises in Europe and the United States.

Even now, CAD technology is not advanced enough.

Xie Kai clearly knew that if such a system existed, it would free their technical developers from a lot of tedious drawing work.

This saves a lot of time.

Calculations can also be made with the use of microcomputers, which further saves time.

There are also computer-aided systems abroad to help generate CNC machine tool programs, but there are no in China.

This makes the 404 base in the research of numerical control system is also subject to a lot of constraints.

"For example, if we want to draw a rectangle, if we use drawings to draw, we have to use a ruler and a triangle to ensure that the straight lines are parallel...... With the use of computer drawing, there will be a special rectangular function module, enter the length and width, and then define the drawing area......" Xie Kai further explained to Zheng Yucheng what is called computer-aided design software.

Zheng Yucheng looked at Xie Kai who was excited, "Is this thing really as useful as you said?"

"Definitely, not to mention anything else, just our 359 tank assembly design drawings, once we have computer design software, all the assembly design drawings can be put together, so that you can see it very intuitively. If we can get the most advanced one, we can even complete the assembly of the entire tank on it, so as to prove whether there is a problem with our design...... "Xie Kai knows that even if foreign computers have been developed for more than 30 years, they are still not as advanced as those of later generations.

He also fought hard to let his father go abroad to see foreign countries.

"How do you know about this?" Zheng Yucheng asked Xie Kai.

"My dad's classmate wrote to him about it, and I had heard about it in Xiangjiang before. The head above must be clear about this matter, you ask, let's do this, if possible, by the way, even office automation is also done......" Xie Kai said lightly.

Letters sent from outside, letters sent from inside, have to be checked by people from the secrecy department, since my father received a letter from outside, Zheng Yucheng will definitely know as long as he asks.

"If we could, it would make our technology developers less tired. Zheng Yucheng nodded and said, "I'll ask when I go back." ”

"Don't wait to turn back, there will definitely be people in our base who know about this. I'm going to ask the computer research institute first. Xie Kai said, "If we want to free our technicians from heavy work, we have to start from many aspects......

Zheng Yucheng didn't suspect Xie Kai.

Call Wang Guilin and others, and they don't know what computer-aided design is.

However, they listened to the role of this technology for the design work, and they all supported the base to do this. Anyway, now that the 404 base is not bad for money, there is naturally no need to rely on manpower to do it.

The Computer Research Institute may be able to know the situation.

As the production line of Factory 619 started and a large number of high-performance chips were manufactured, the Computer Research Institute of the base began to study microcomputers and design and assemble supercomputers with stronger data processing capabilities.

"Welcome leaders to come to inspect and guide the work!" Shen Haipeng is happy all day now, they are no longer the same as before, nothing has happened all day.

"Don't talk about useless things. Computer-aided design system, do you know about it?" Zheng Yucheng glanced at Shen Haipeng and directly explained his intentions.

Now the situation is improving throughout the base.

"Director Zheng, you're asking the right person. I thought, foreign small and medium-sized enterprises are beginning to promote, why do we have to do this...... Who, you go and call Ao Mo to come over, he understands this technology. Shen Haipeng said sneeringly, "We are now preparing to build an auxiliary design system, and Ao Momo is the project leader." ”

"Don't forget?" Xie Kai felt that this person's name was a little strange.

Whether it's a first name or a given name, it gives people the unreal feeling of a screen name.

"Leader, are you looking for me?" Director Zheng is good, Director Wang is good ......" Ao Mo Forget (played by the reader Ao Shi God and Demon King) came over, Xie Kai saw that he was actually a fat man!

A very young fat man.

In particular, the smile on his face made his eyes become a slit, giving people an extremely obscene feeling.

Xie Kai wondered, why didn't he find this product before?

There aren't many fat people at the base.

Especially if it's so fat, it's still short!

He also wears a pair of giant black-rimmed glasses that cover half of his face.

Like his name, it's all weird.

"New here?" Zheng Yucheng was obviously not familiar with it either.

"Back to Director Zheng, the little one has been in the base for 4 years, just in time for the most sluggish years of the base...... Fortunately, the cold winter of our base has passed since last year...... "This kid is completely self-cooked."

Xie Kai couldn't help but be interested in him.

In these days, there are not many people who talk like this.

"Don't be useless, Director Zheng, they come over and ask about the computer-aided design system, you can introduce it, and then fool around, I'll let you clean the toilet!" Shen Haipeng is very good to this fat man.

"Where did you find a living treasure? If our technicians were so lively, we wouldn't be so worried...... Zheng Yucheng asked Shen Haipeng with a smile.

Shen Haipeng was a little embarrassed.

It turned out that this kid was too embarrassed and he was not allowed to appear in front of the leader.

"Ladies and gentlemen, what do you want to know? Is it the current project being studied by our computer research institute, or is it the situation of the use of computer-aided design systems abroad?" asked Zheng Yucheng.

"Tell us about what you know about foreign applications, and then talk about your research projects. Zheng Yucheng said.

"Director Zheng, let's go to the conference room, this thing, one or two sentences can't be explained. Ao Momo still had a smile on his face, regardless of whether their leader had not yet spoken.

Zheng Yucheng and others were noncommittal.

Xie Kai saw this fat man, and he was also Zhile, it was really a wonder, but the base needed such a wonder, otherwise, he would always look serious, too depressing.

He also thought about coming to this place more often in the future to talk nonsense with fat people.

Regarding the matter of letting his father lead a team to go abroad for an investigation, Xie Kai didn't think that this obscene fat man could affect it at all.

He knows better than anyone else about domestic technology in this area.

Many companies use it in the back, or even use the cracked version, not the genuine version.

"Ladies and gentlemen, Computer Aided Design, referred to as CAD, is the use of computer software for graphic processing......" Ao Mo's introduction is much more professional than Xie Kai. "The initial appearance was that the U.S. military system in order to support the CNC milling machine, with the expansion of the function of the software, the role was highlighted, and began to extend from the U.S. military industry to the civilian market......"

Zheng Yucheng and others listened to the introduction of Ao Mo forgetting, especially the development of this technology abroad, the effect and function of use, and how to use the product design process......

"Turtles?" Xie Kai asked when he was about to introduce him.

"I'm a real Chinese turtle. Originally, the school was going to arrange for me to study abroad, but I didn't want to, and then, I came here......" Although Ao Momo smiled, his voice was a little bitter.

Xie Kai understood.

"In fact, this kind of technology is also being studied in China, and some simulation operations of supercomputers are used more in the fields of aerospace and aviation. Ao Momo continued.

"We have it in China? Then we can get it from a unit that has this technology. Zheng Yucheng really wanted to see for himself how this thing was designed without pencils and drawings.

"Director Zheng, even if we get it, we can't use it. The simulation system on the aerospace side is specially designed, and all kinds of models are related to rockets, and the data is also ...... What we need is a generic CAD design software. It is possible to design mechanical circuits and even integrated circuits for chips......" said Ao Moyu seriously.

Xie Kai nodded.

If there is one on the aerospace side, it is not a problem for the base to get it.

Supercomputers originally existed to justify complex calculations in the field of scientific research and to justify some designs. Naturally, there have to be dedicated models.

If the base wants to promote design software and let computers free people from heavy drawing work, it must use general-purpose CAD software.

"That's the case, what is the situation of what you are doing, how long will it take to get it?" Zheng Yucheng felt a little regretful.

"Director Zheng, if there are enough manpower, we may be able to come up with a basic framework within three to five years......" Ao Mo's words immediately made everyone's faces darken.
