This is a remarkable achievement in the field of CAD.

At this time, whether it was Robert Hugh, Edward Williams, or Roman Rohdes, they had already seen the revolutionary significance of this CAD software.

It not only represents the development direction of CAD software, but also contains some design concepts, which let everyone see the bright future of digitalization in the manufacturing industry.

You must know that after the computer revolution in the sixties and seventies, CAD/CAM/CAE/CAPP (computer-aided design, computer-aided manufacturing, computer-aided engineering, computer-aided process planning) and so on have been proposed, and the digital prototype of the aircraft has become the goal that all aviation people tirelessly pursue.

BUT BEFORE THE ADVENT OF AUTOCAD, THE FREEFORM PROBLEM OF CAD ALONE PLAGUED ALL AERONAUTICAL ENGINEERS.

A large number of complex surface problems not only mean a huge amount of manpower, material resources and time costs, but also before the freeform surface problem is solved, CAM/CAE/CAPP and so on are simply impossible.

THE ADVENT OF AUTOCAD MEANS THAT NO MATTER HOW COMPLEX THE CURVED SURFACE, IT CAN BE BUILT ON THE COMPUTER, WHICH MAKES TRUE DIGITAL MANUFACTURING POSSIBLE.

You must know that in recent years, with the rapid development of computer technology, the manufacturing industry in the United States is facing huge pressure for industrial upgrading.

This represents a huge market worth tens of billions of dollars for the CAD industry.

Just look at how many companies in the CAD field have popped up in the United States over the years.

Lockheed's CADAM, General Electric's CALMA, Boeing's CV, NASA's i-deas, McDonnell Douglas (MD) UG...... These manufacturing giants either independently develop or actively support some more promising CAD software companies, wanting to take a share of the CAD market.

LATER, SOME OF THE INDUSTRY GIANTS SUCH AS THE WELL-KNOWN UNITED PARAMETRIC TECHNOLOGY COMPANY AND AUTODESK COMPANY HAVE NOT BEEN ESTABLISHED AT ALL, AND SOME HAVE JUST BEEN IN THEIR INFANCY AND HAVE NOT YET BLOOMED.

AUTODESK, FOR EXAMPLE, HAS GROWN TO BECOME THE WORLD'S LARGEST 2D AND 3D DESIGN, ENGINEERING AND ENTERTAINMENT SOFTWARE COMPANY IN YANG'S TIME, PROVIDING DIGITAL DESIGN, ENGINEERING AND ENTERTAINMENT SOFTWARE SERVICES AND SOLUTIONS FOR MANUFACTURING, ENGINEERING AND CONSTRUCTION, INFRASTRUCTURE, AND MEDIA AND ENTERTAINMENT.

And its first product is the design software with the same name as Yang Weining's AUTOCAD.

IT'S JUST THAT COMPARED WITH YANG WEINING'S AUTOCAD SOFTWARE, WHICH DRAWS ON A LARGE NUMBER OF MATURE ALGORITHMS AND DESIGN CONCEPTS FROM LATER GENERATIONS, AUTODESK'S SOFTWARE IS ALSO A LITTLE TRANSPARENT, AND THE FUNCTIONS AND MEANINGS OF THE TWO ARE NOT THE SAME AT ALL.

Yang Weining's AUTOCAD, in terms of technology alone, has reached the world's top level, not to mention its important role in promoting the entire manufacturing field.

"No, we have to get our hands on this software!"

Robert Hugh flashed a glimmer of light in his eyes, whether it is Edward Williams on behalf of Boeing or Romain Rod on behalf of Lockheed, they have seen the great significance of this software, but these two companies have already laid out in the CAD industry, once they get AUTOCAD, it will be extremely detrimental to the future development of Grumman.

Hugh only hesitated for less than five seconds, then suddenly raised his hand and interrupted Yang Weining's speech: "Mr. Wei Ning Yang, do you have any plans to sell your AUTOCAD software?"

Hugh's sudden voice not only surprised Colonel Harper, Edward Williams, Roman Rod and others, but even Lu Wenjun and Yang Zhenguo were dumbfounded.

Although they have long seen the interest of Americans in this software, they never expected that the other party would actually speak for purchase during the introduction process.

Isn't this clearly for people to slaughter?

Even Chinese, accustomed to the planned economy, saw Hugh's unusual behavior, not to mention the experienced Edward Williams and Roman Rohdes.

"Old fox!"

Edward Williams and Roman Rhodes cursed in their hearts.

They couldn't see Robert Hugh's mind.

Originally, they still had a tacit understanding that after the demonstration was over, they would contact the Chinese government in private, and then there would be many means of black-box operation.

But as soon as Hugh was disturbed, all their plans were suddenly in vain, and Grumman made it clear that they were determined to win AUTOCAD, so did they still have a reason not to fight.

For a while, Edward Williams and Roman Rhodes spoke one after another.

"MR. WEI NINGYANG, AUTOCAD IS REALLY YOUR GENIUS, AND BOEING IS VERY INTERESTED IN THIS SOFTWARE. ”

"LOCKHEED IS THE SAME, YOU HAVE DEVELOPED AUTOCAD WITH GREAT FUNCTIONALITY, AND WE LOOK FORWARD TO WORKING WITH YOU FURTHER IN THE CAD FIELD. ”

Even Cahill, the senior vice president of Raytheon, who had been watching the excitement, was not far behind: "Mr. Wei Ningyang, Raytheon is also interested in your AUTOCAD. ”

Cahill is naturally not a fool, AUTOCAD can cause Grumman, Boeing, Lockheed and other giants to scramble, that is definitely a good thing, if such a product can fall into the hands of Raytheon, naturally there is no benefit.

For a time, the five-member delegation of the American aviation community and the representatives of the four enterprises had all taken action, and the only one who did not speak was Colonel Harper, the US military attache in China.

Harper was completely dumbfounded at this time, just now he already knew from Hugh that the software developed by Yang Weining was very powerful, but no matter how powerful it was, it couldn't reach the level of competing in public in front of the public, right?

You are the cornerstone of America's strong air force and the guarantee of a strong manufacturing industry, so you are competing for a software from China, if it spreads, will you be ashamed?

Thinking about the fact that these people had been complaining to themselves about the investigation in the 611 Institute for the past two days, Harper couldn't help but feel like a dog in the middle of the day.

Yang Weining didn't care much about everyone's reaction, the software that he took so long to develop contains the essence of the 30 years of development of the CAD industry, if it doesn't cause a scramble, it would be strange.

He smiled and said, "I'm sorry, Mr. Hugh, Mr. Williams, Mr. Rhodes, Mr. Cahill, this software means a lot to our country, and it is not for sale at the moment. ”
