The first thing Mu Yang needs to solve is the 3D design software. Even by 2022, he will not be comfortable using many functions of several 3D design software.

For example, in the three-dimensional design software SOLIWORKS, it is possible to convert three-dimensional drawings into two-dimensional CAD drawings (the two-dimensional CAD drawings are construction drawings and must be marked with processing dimensions so that workers can understand them. Three-dimensional drawings are not suitable for use as construction drawings.

, but it is very intuitive. Generally, the drawing is a two-dimensional CAD drawing + a three-dimensional drawing. It can not only understand the size of the drawing, but also intuitively understand the appearance of the workpiece, and it is not easy to process errors. Otherwise, some people will make mistakes when looking at the CAD drawing.

Wrong picture).

However, there are many problems with converting 3D drawings to CAD, such as the marked dimensions are silly, the fonts are too small and cannot be read clearly when printed, the dimension chain is incorrect, and unnecessary dimensions are marked, well, there are too many anyway.

Generally, the mechanical designer re-marks the dimensions, which is quite troublesome.

Of course, you can also design a template, but it's not easy to use.

Also, the conversion of CAD images into three-dimensional drawings cannot be achieved perfectly.

If there was a software that could directly convert the CAD drawing into a three-dimensional drawing without dragging the height and length, it would be perfect.

The current software function, when converting CAD drawings into 3D drawings, requires deleting some irrelevant annotation text for easy operation. In fact, it is no different from stretching a 3D drawing sketch.

What Muyang wants to solve is that, for example, the current CAD drawings drawn by the company do not need to be added or deleted. The new software will automatically recognize the needs of mechanical engineers. The designer only needs to select the closed-loop area to naturally generate a three-dimensional drawing, and

Generating data allows for design.

It is very difficult to realize this function. If it can be realized, there are some designers who do not know how to use 3D software. They do not need to draw 3D drawings, they can just draw 2D drawings. After drawing, they can be converted directly. Some people draw CAD drawings.

Being more proficient does not mean that using 3D software to draw drawings or CAD drawings is the best.

To draw a three-dimensional painting well, you also need to convert it into a CAD drawing. It is more troublesome to produce the drawing. This is also a problem that Mu Yang needs to solve.

In this era, especially older designers, they really don’t know how to use 3D design software. Many companies do not mandate that they must know 3D. However, with the development of the times, higher requirements are put forward for mechanical designers, and they do not know how to design 3D.

The software is really bad.

Software is simple to use and easy to learn, but it is difficult to master it.

In addition to the above problems, there are many problems with current 3D design software.

For example, if you want to select an M8 bolt, if the software has a standard library, the thread is metric (different from the American system), and the lead is a common type. It also has a length that must be selected. There will be different lengths in the standard library.

Material of M8 bolt.

If it is designed by Muyang, the software must be connected with the company's real-time warehouse inventory and market information. For example, if you select a 60-length bolt, it will show that it is not available in the warehouse or even in the market, but it is recommended to have a 70-length bolt because the warehouse happens to have it.

, as long as the assembly does not interfere, it can be used. As for the bolts, it doesn't matter if they are longer, but they cannot be short.

However, if this function is not available, after the drawings are issued, it is discovered that bolts of this length cannot be purchased, and it is impossible to process them. The processing cost is too high, and we can only find substitutes. These processes will undoubtedly increase the cost, and the drawings will have to be modified.

, re-issue the drawings unless investigated clearly in advance.

But designers are too lazy to check the company's warehouse inventory list.

As for this real-time warehouse information, the company has established an ERP warehouse management system, which can be combined together. To implement this module, the company needs to do a good job in warehouse data management, and the data must be consistent with the actual situation;

As for market information, the purchasing department needs to do a good job in data statistics management, which is more troublesome to collect and the workload is very heavy.

This is just a metaphor for a commonly used standard part, but these data can be handled by employees. Mu Yang does not need to be responsible for supplementing and maintaining it. He only needs to write the 3D software with logical functions and modules.

For another example, Muyang only needs to draw a hole. If there is a function that prompts the bolts, nuts, and washers required for matching, you only need to select and confirm, and they will automatically fit together. It is a fool-proof design, and there is no need to start from the standard.

When assembling, you also need to find a reference plane for assembly. If the holes are asymmetrical, you have to assemble them one by one, which is too cumbersome.

To achieve this function, it is an identification function. For example, if a hole with a diameter of 8.5 is found, if a bolt and nut are to be assembled, the software will automatically recommend an M10 nut and even provide the length of the bolt.

In terms of programming logic, the first step is to determine that there is a hole, and then determine the size and depth of the hole. If you want to screen out more suitable nuts and bolts, you have to compile a formula.

Formulas and logic are very important. For example, there will be many holes of different sizes. If one formula can solve it, it will be convenient during runtime. If it takes dozens of formulas to solve, the logical judgment will be very troublesome, and the number of program lines will be very long.

There are also many functions, such as welding module, sheet metal design module, steel structure design module, etc., which can be integrated quickly.

There are too many problems that need to be solved. If it can solve the above functions, it has surpassed all 3D software on the market and become the 3D software with the highest technical level in the world.

Mu Yang rubbed his head, stood up and walked around.

Song Xuelu was a little bored at home, so she walked lightly into his office, saw him rubbing his head, and asked with concern: "Husband, take a rest if you are tired."

Sit next to Mu Yang and make him a pot of tea.

There are drinks and red wine in the refrigerator, but Mu Yang feels that drinking too many drinks is not good for the body. He is not a good drinker either. Red wine is not as refreshing as beer if it is just left alone.

In winter, it is impossible to drink beer, and he is in the office. Although no one cares about him, his image is not good.

The single-floor area of ​​Xinghai Building is 3,000 square meters. The higher the floor, the smaller the area. The 98th floor also has 2,600 square meters. They are all high-rise offices. In fact, they are inexhaustible. Currently, there are only a few people on the top floors. Plus

Secretary's office.

Muyang's own office covers an area of ​​200 square meters, and the glass windows just face the West Lake, making it the best location for sightseeing.

The offices in other high-rise buildings are relatively small, about 70 to 80 square meters.

Mu Yang took a good look at his wife next to him and asked gently: "Are you bored at home?"

"No, I just missed you. I came down to see you." Song Xuelu smiled slightly and brushed her hair beside her ears.

She has been pregnant for more than three months, and her belly is slightly bigger, which is more obvious. Now she wears looser clothes, specially customized.

Mu Yang picked up the tea, drank a few sips, and had a casual chat with his wife.

The two talked about drawing software, and Song Xuelu even complained, saying that the school's CAD software was not very good.

"Husband, don't those companies buy genuine CAD?"

Mu Yang smiled, thinking that his wife might not know much about the situation of domestic machinery companies, so he explained: "Honey, it's not that Chinese people don't want to buy genuine software, it's just that it's too expensive.

A small machinery company may only have a few designers, or even one person. Let these companies spend 20,000 to 30,000 yuan to buy a set of top-notch software, and have to pay the fee every year. The owners of such companies are not willing to do so.

Hey, not to mention the foreign brand CAD that costs 20,000 to 30,000 yuan, the domestic brand CAD that costs several thousand yuan every year are not willing to pay, it is just such a reality."

Song Xuelu was a little surprised: "Is genuine CAD so expensive? I thought it would cost a few hundred yuan, maybe one or two thousand at most."

Mu Yang said: "Well, I know about the market. Now a domestic CAD set costs 8,000 yuan, which is only a yearly fee. Foreign ones are more expensive, usually 1,600 US dollars a set, and the best ones are not sold yet."

For us, it may be a castrated version, and it may not be applicable.

Note that this set of fees refers to the installation fee for one computer!

If the whole company can use it, how much money will they make? It's just that there are discounts for large installations.

To be honest, domestic brands of CAD come with a lot of tool plug-ins, which may not be useful, and are a bit useless, but in any case, they are definitely much better than pirated ones.”

Song Xuelu nodded: "The cost of use is too high, and users are unwilling to use it, it is true."

"Yes, these bosses feel that the money they spend is better spent on recruiting people. In our country, the awareness of using genuine products is relatively weak."

Mu Yang complained.

Of course, software companies also hope to be able to charge a relatively cheap fee every year like some companies. As long as the number of users is large, they can still make money.

However, most software companies are not well-known and do not have the strength to do this. In the end, they just want to make money. This is of course true. If a company does not achieve profitability, it cannot continue to operate.

So, this is the difference between entrepreneurs and capitalists.

Capitalists only seek to achieve profits and maximize profits. The first thing that comes to mind, like Mu Yang, is how to break the monopoly of overseas giants, achieve localization, how to improve national technology and enhance national strength. Of course, money is made by the way.

Song Xuelu sighed: "No wonder, the CAD used in our school is still so backward. In fact, I don't want to spend that wasted money, and the genuine software is not much better. I feel that I would rather spend more time drawing."

Mu Yang spread his hands and expressed his helplessness: "There are useful ones, but we just can't afford them. The teaching CAD version in universities is indeed backward. It is impossible to imagine that large companies can use the latest genuine CAD.

Then, the CAD used by students for study is completely different from that used by enterprises. Some mechanical graduates are new to the company and open the company's CAD. They are confused at first glance and cannot use it at all.

Of course, if you have a CAD foundation, you can learn quickly.

It’s just that this is the case with CAD. For example, 3D software with higher technical requirements is completely different, and the learning and adaptation process is relatively long.

If it is the result of finite element analysis, pirated software or junk software, it may mislead the calculation results.

For these technically difficult software, the genuine fee is particularly high.”

Mu Yang continued: "I have a goal. If these industrial software are made, then I will open it to universities and colleges for free, and will only charge companies, even small workshops, or only one or two industrial users."

Small software companies or individuals only need to pay a very low price every year to use very advanced industrial software.

But overseas, the charges are very high.”

Mu Yang has no intention of making money from the software, but as long as the volume is large, he can still make money.

Generally, companies cannot do this. Firstly, they are not famous enough, and secondly, they do not have the capital to play like this. They basically lose money in the early stage.

Muyang's set of commercial methods is actually Lao Shi's set of methods. The free ones are the most expensive ones.

As long as these mechanical graduates from universities are recruited, within eight years, these people will basically become the backbone of the company.

Therefore, within eight years, the entire domestic market will be owned by Muyang, and by that time, there will be no second type of industrial software on the market.

In fact, Muyang doesn't want to open these software tools to foreigners. If he doesn't make much money, it's not necessary. He might as well let domestic companies take away overseas orders.

Huaguo's design plans are produced quickly, the project cycle is short, the overall cost is much lower, the delivery cycle is fast, and it is more competitive in the international market. It can directly defeat its international counterparts and let foreigners know what Huaguo's speed is.

This is what Mu Yang wants to see most, what's the point of making that money.

Of course, if you have more money, it will also be very delicious.

For example, for a company with less than 10 people, a set of software costs US$10,000 to US$20,000 per year as a membership fee. This fee is a bit excessive, but not outrageous.

A company with only about a hundred designers needs to pay at least hundreds of thousands of CAD fees a year, no matter how favorable the software price is, and the software is not that good.
