The State Machinery Industry Committee can initially be satisfied with the two-dimensional CAD drawing software, the reason is that the Ministry of Agricultural Machinery, the State Administration of Instrument and Meter Industry, and the State Machinery and Equipment General Administration under the Machinery Industry Committee are all designed to design some simple mechanical equipment, usually using two-dimensional drawing software is enough.

However, in the field of aerospace and ship design, as fluid mechanics continues to be combined with the development of the industry, the design of products is becoming increasingly complex, and the design requires a high degree of integration, compactness, and seamless connection of high-precision surfaces, which can no longer be expressed by traditional 2D CAD.

The two research institutes under the Shudu Aircraft Development Center have specially introduced Dassault Systèmes' aviation-grade 3D CAD products, and the use effect is good.

The resulting efficiency improvement, naturally also in the eyes of domestic counterparts, leaders, dozens of domestic large and small key military units are all shouting that this requires the introduction of foreign three-dimensional CAD software use, but the price of that thing is ridiculously high.

Anyway, if all of these are satisfied, don't think about stopping without tens of millions of dollars, and this is only the software, if you want to give these units a full popularization of CAD-aided design, you have to include a variety of hardware procurement, personnel training needs, dare to ask which of these does not cost money?

After all, these are dozens of key domestic military units, and where the market demand is placed, the total amount is absolutely amazing.

In line with the starting point of thrift and thrift, and now the domestic has purchased reference samples, if you don't want to imitate it, it is really blinded by lard.

The Ministry of Aviation Industry has given full support from the beginning of the research and development of the Xeon project, and now that the computer has been successfully developed, of course, people must also get their own benefits, and this foundation has been hanging in the Ministry of Aviation Industry, and it is still necessary to get some benefits from it.

So the task of developing domestic 3D CAD software was handed over to the 611 Institute under the Shudu Aircraft Development Center, after all, the foundation has part of the profits every year through the channels of the 611 Institute to invest in the aviation field, from which to take money to develop 3D CAD software, it is a matter of course.

It is still the software company that developed 2D CAD before, and this time it was directly funded by the Ministry of Aviation Industry and the Machinery Industry Committee.

Among the two large industrial ministries with the prefix of the state, the 611 Institute of Shudu Aircraft Development Center of the Ministry of Aviation Industry invested 3 million yuan, accounting for 40% of the company's shares, and the Machinery Industry Committee invested 500,000 yuan, accounting for 10% of the dividend shares, and the two sides jointly invested in the development of 3D CAD software based on the operation of the Hetu system environment.

Considering the importance and influence of CAD software, Yuheng Software also made a symbolic investment of 500,000 yuan and asked for 10% of the dividend shares, so as to ensure the absolute control of the founder of the software company over his company, and there will be no possibility of being kicked out of the company in the future.

In fact, the foreign 3D CAD software market has entered the stage of competition, Dassault Systèmes, CV, IBM, Intergraph, Calma, Appli, ApliZeneca, Mcauto and so on......

In detail, at this time, there is a high degree of integration between 3D CAD software and hardware, and a 3D CAD software must achieve deep interaction with professional work in the development stage, which means that software and hardware cannot be separated.

Even if it is run and used on the workstation, the 3D CAD software at this time still follows the DOS command flow route, that is, the draftsmen and product design developers input English to the workstation and use various shortcut keys to complete the operation command input.

This is the fundamental reason why later CAD software entered the era of graphics systems, and there are still many software that can support shortcut command operations, and even many so-called speed drafters do not use a mouse.

For example, in Auto-CAD, there are various command prompts and shortcuts: L-line, C-circle, REC-rectangle, O-move, M-move, CO-copy, RO-rotate, T-text, TR-cut reduction, PL-polyline, E-delete......

This can't be helped, the old software is developed from the DOS system era, even if it enters the graphics system era, they still retain the DOS system era genes to some extent.

Now, the three-dimensional CAD software developed based on the Hetu operating system may not be as professional as the workstation in terms of performance, but it will not be much worse, and the main thing is that this product can be more easily interacted with the designers of the Republic and more convenient to use.

In a word: the experience is excellent!

Why is the CAD software of the upper plane in the eighties and nineties only limited to the top research institutes in China?

That is, because the imported software is developed based on the DOS system, the user must first understand English, and how many people can understand English and play with the computer in the research institute?

That is to say, the large key research institute is full of talents, so that it can find suitable personnel to go abroad for training and learning software use, and no one in a small unit can really play.

Two-dimensional CAD is fine, there are not many operating commands anyway, and you can remember the operation commands by rote memorization, but the complexity of the three-dimensional CAD command is far from being done by rote memorization, and it is naturally difficult to roll out the three-dimensional CAD on a large scale before the popularization of the graphics operating system.

Wang Zhengguo has every reason to believe that as long as the product is successfully developed, the domestic CAD-aided design can be rapidly popularized, and it can absolutely monopolize the domestic market in the next five to ten years.

After a few years, foreign countries gradually transition CAD products to the era of graphics operating systems, and the domestic side has already become the climate, and at that time, foreign CAD developers had better pray that the Republic of China will not kill this set of software to the international market.

Being able to provide the best basic technical support in the field of industrial design, which has led to the great strides in the field of industrial design in the whole Republic, is the most important place to be reborn.

No matter how good it is in one application field, it is only a well-known field in this field, but if we can popularize CAD as a basic industrial technology ten years ahead of schedule, it will bring unimaginable benefits to the entire country and society.

Relying on the popularization of CAD and improving the efficiency and accuracy of industrial design, so that manufacturing factories and companies can be saved, I am afraid that it is really not simple to be counted.

Looking back at the domestic 3D CAD development company that has high hopes, since the time of the 2D CAD era, this company has developed rapidly, and the core development team is currently as high as 34 people, Wang Zhengguo of course also has high hopes for this company.

If it can really succeed in developing 3D CAD, Wang Zhengguo can continue to support it to become bigger in this area, if the military research institute designs all kinds of highly complex military products and large-scale equipment is so complex that it can only be achieved through forward development, so it needs 3D CAD.

The simple civilian copycat imitation to become bigger and stronger, the same is indispensable for computer-aided reverse, as far as it seems that most of the basic conditions for computer-aided reverse software have matured, it depends on whether the company is enough to compete.
