UG master's self-admission

Landlord, it is difficult to answer your question, because the advantages of the two softwares are different when designing different products. I have advanced design certification of PTC and UGS, but to be honest, I must choose according to the design goal when I apply it in practical work. I don't quite agree with the explanation on the first floor. Personally, I feel a little one-sided.

The modeling function of UG is very complex and huge. Except for natural fillet, almost all features must be based on sketches, so the design process of UG is very tired, and seemingly simple and unimportant things such as layer management will affect the whole design. UG's surface modeling function can be described as invincible in the world, so it is mostly used in structural parts with complex surfaces, such as the outer surface of car body, the outer surface of industrial equipment and the internal transmission mechanism. However, when UG is changed after design, it is often necessary to see whether the reference plane selection is reasonable at the initial design, otherwise the design will be completed, but it cannot be changed, or it will be redrawn after the design is changed.

The general modeling function of Pro-E is also very good, but the surface function is not as powerful as UG. The modeling process of Pro-E is relatively simple and has relatively few constraints. It's easier to change later, except when you get it wrong ... basically, there are few designs that Pro-E can't complete. Functionally, as long as the surface is not too complicated, the design process of Pro-E may be simpler.

Therefore, if the surface with the function above 18 is not made, the functions of UG and Pro-E are basically the same, and both can meet the engineering needs. Generally speaking, UG is stronger, but more complicated. It is generally acknowledged that learning UG is much more difficult than learning Pro-E, because without detailed guidance, self-study is difficult to get started, and people can't find their way with only seven coordinate systems. Then don't say anything about software.

In addition, I graduated from mechanical and electrical major and now I am engaged in mechanical design. If you study mechanical manufacturing, there is no need to learn such professional design software. What you need to learn more is how to read drawings professionally. Learn mechanical design, both of you should understand. If you study mechatronics, it depends on your future work direction. This major is too broad, and you may need everything or nothing.

My advice to you is that as a mechanical engineer: UG, Pro-E, SolidWorks, SolidMX, CATIA, Alias, MasterCAM, AutoCAD, etc., the more you learn, the better. It is necessary to master one or two of them. At least what I said above, I have been studying for several years, and application is the most important. During this time, the company used Pro-E, and my UG was almost forgotten.

Tell me a little more. In the past, when using UG, there were 1.6 million workstations (more than 20,000 graphics cards of Wildcat 4). It was a bit too much to assemble 1.6 million units, which had many functions and consumed a lot of system resources. But with Pro-E, my current workstation is only 3 1000, and it is not a problem to assemble 2300 sets. Moreover, companies generally need more than 300,000 sets (basic modules) to buy genuine UG, while Pro-E only needs about 1.8 million. In these respects, most companies use Pro-E. If you are looking for a job, Pro-E may be more practical and have a wider range of applications.

Autocad is out of the scope of discussion. This is the most basic thing. Any engineer, if he can't, will buy tofu and kill himself.

Ben Gok, hello!

First of all, thank you very much for your comments. Everyone complements each other, but to be honest, I don't agree with many things for the time being, and I want to communicate with you:

1."Pro's sketch function is not strong, so it is used less."

Will UG be faster than Pro-E except drawing squares? Pro-E's central symmetry line function can achieve twice the result with half the effort, especially for later plotting. Its sketch size can be directly displayed on 2D, and the 3D model can be driven by 2D size. Can you UG? 99% UG sketches must be sorted and hidden when they are plotted, right?

2. "Second," but when UG changes after design, it is often necessary to see whether the reference surface is reasonable at the initial design, otherwise it will often cause the design to be completed, but the design cannot be changed, so it is better to redraw it. "pro/e also has this problem, which is a common problem of 3D modeling software. Pro/e is mostly parametric modeling, which is really convenient to modify when the modeling is relatively simple, but

Excuse me, what did I do wrong? Please read the full text.

3. "Once the modeling is slightly complicated, the modification of parametric modeling is not necessarily more convenient than nonparametric modeling. Because many parameters are interrelated, it is not unrealistic to say that in another place, other places will change! "

What is your definition of complexity and simplicity? In the whole parametric modification process of Pro-E, even if there is an error, although the processing process is very complicated, after all, problems such as missing parameters or interference conflicts can be solved through reasonable repair. However, once UG encounters these problems, it will only display "Error, command aborted!" " ".I don't think you have. Staring at a feature is not changing, and you can't figure out why not. If so, do you still insist?

4. "Ug learning is not much more difficult than Pro/E. There are seven coordinates in UG, but in fact we don't need to pay attention to it at all. As long as we adapt to the idea of three-dimensional modeling, we won't feel anything on the seventy coordinates! " I won't comment on this sentence. I respect your opinion, but please refer to the major domestic mechanical forums and let the numbers speak for themselves.

"UG has many modules and many functions, but it doesn't mean that we all have to study and specialize in several modules. Some modules may not be used for a lifetime, such as pipelines, such as shipbuilding, such as aviation sheet metal. " If you think what I said before is wrong, then I'm welcome here. Find someone who has never used Pro-E, and I will teach him 1 hour basic modeling, with no more than 20 common commands. Are you saying this to compete with me for more food? I think that's what it means.

5. "Nowadays, mechanical manufacturing can not only read drawings, but also operate machine tools. Now most of them are CNC machine tools. You have to know how to program on NC, draw a line cutting diagram on online cutting and draw electrodes on EDM. These UGs can be used, and the processing of pro/e is much worse! "

Have you ever worked as a manufacturing engineer? Please distinguish between mechanical engineers, manufacturing engineers and operators first. In recent years, everyone has called me "worker M". I'm sorry, I can't program NC, and I never intend to learn it. Do all mechanical engineers around you do these things? Then the operators in your company must clean the machine.

Don't mention it, how much do you know about NC machining? I don't know that Amada's NC can directly read AUTOCAD files for automatic programming as long as it is above 4000? According to your theory, AUTOCAD is the strongest! Even people are saved.

6. "And you said 300,000 sets of UGs (basic modules). I don't even know where you bought UGs. You must have been cheated." 300,000 sets, this sentence was said by Qin Zheng, the sales manager of UGS Shanghai Representative Office, and I named it directly. If there is any objection, I will check it directly by phone. Please pay attention to your information source.

"UG grows faster than pro every year in China, because many big companies adopt UG." UG is growing, but please look carefully at the major recruitment websites and ask about the needs before you come to a conclusion. Besides, I am in Shanghai, and there may not be too many big companies. At least I have worked in four Fortune 500 companies (including now). Colleagues and friends in the same industry are all over the major companies. It can be reported that no more than 10 companies use UG (including Shanghai Volkswagen, GE, etc. ), but countless people use Pro-E.

7. "HP's workstation is less than 2w, a complex set of molds, hundreds of units, and the final assembly file is nearly 2 G."

I will forward this sentence for you separately, please forward it to major forums and anecdote pages. I haven't eaten yet, so I have nothing to vomit for the time being.

In fact, I don't really want to say your evaluation of me, but your evaluation is absolutely biased. The function of UG is better than that of Pro-E, but you belittle Pro-E too much. Besides, don't bring up any topics. If we must say something, let's talk about SolidWorks, Alias, CATIA, SolidMX and MasterCAD respectively. Many things you say seem to be tools for you to show off and attack before others verify them. For example, we can communicate privately, because everyone is beside the point.

Sorry, landlord, I added so much extra words. I am disappointed to see such a poor thing. Please close this post directly.

Get better again,

I'm glad the tone of your reply has changed a lot. If that's your attitude from the beginning, I wouldn't have published the above reply at all.

As for your other opinions, we have basically reached an agreement. Even if we disagree, our position is correct, but the following principles still need to be pointed out:

4. I am the team leader of the company's mechanical design, and I have TTTT three-level certificate. My second job is to train new people between projects, so I will study so many softwares. My students should be no less than 100. I can say responsibly that as long as the other person's IQ is not too low, I can completely meet your teaching requirements.

Please note that my reply to you is based on your crazy devaluation of Pro-E, not on how strong Autocad is. Also, as you said, amada's 4750 can indeed process surfaces directly with cad files, but will you abandon your UG because of this? I think you also know how painful it is to build a 3D model with CAD? Even though cad is very strong, why are we still using UG and Pro-E? Please understand the premise of our views on each other first.

By the way, I don't know what kind of company you are in. I have worked in Japanese, European and American companies in recent years, except state-owned enterprises. At least in these companies, CNC-related work is done by the production technology department, and it is not done by engineers in this department, but by front-line workers. None of the engineers I know can do it. It's not that these jobs are low-level, but that the division of labor is different. There is no need to learn. Hobbies are another matter. Excuse me!

6. Qingdao Matrix Company inquired that they are the general agent of UGS products in Qingdao. You ask the agent, I ask UGS Shanghai branch. Who do you think is more accurate?

Also, Matrix Company is a PDM-based company, which develops E-matrix for Pro-E, and does not sell UG and Pro-E at all. And E-matrix is a PDM developed for Pro-E. Why do they sell UG instead of Pro-E? I'm confused.

Qin Zheng called me 20 times a day for my previous company's 150 global stocks. Everyone knows that the global sharing license should be cheaper than the stand-alone license. Many agents sell second-hand licenses or incomplete versions, or limited-time versions of software. I hope you didn't get caught.

7. First of all, I don't doubt the price of HP workstations. Secondly, I don't doubt the number of your units. 300 sets is not much. But your opinion is that such a large-scale modeling can be operated with such a workstation? Do you know anything about simplified models? The workload of an engineer is limited. I can finish the assembly design of 100 drawings at most every day for a month, so I believe that you don't do much of these 300unit yourself. So if you are lucky enough to assemble this assembly document yourself, then I ask, do you need to simplify the model? If you don't need to simplify the model, if you still say that it can be operated, it is a big joke; If you use a simplified model, imagine a workstation with 20,000 PCs, and its graphics card is at most a non-professional graphics card like Lee Tae 7400. I believe you can open this final assembly file for half an hour, and then delay it for a little while and then spend 1 hour. If you point out the invisible line, it is estimated that half a day will be enough. If you insist that this is feasible, then I am speechless.

Please note that the above are units, not parts, and 300 parts files can be completed by my ordinary computer at home.

Just read the posts you sent to others, and they all praised UG to the sky. To tell the truth, my UG is far better than Pro-E, and I also know that some advanced surface functions UG are very strong. I said in the original post: /UG's surface function is a Chinese odyssey. But please put yourself in a correct position when commenting objectively. Pro-E is not useless (this is my position to reply to your post), and even Autocad has a huge market. Any software, existence is the reason.

Similarly, I don't want to convince you, but I don't want others to be misled by you. The landlord is asking for advice, and it is most important to give him a correct choice through objective comments. If you don't mind, we'll stop and have a look!

Then go to Bengoak,

Since you are so interested, I will continue to write with you:

1.

I would like to add that my certificate is designer certification, UGS certificate is in English, and the title of the certificate is "UGS product advanced design approval". Please translate it into Chinese, and then discuss if there is any problem with what I said.

The certificate has a unique serial number in the lower right corner. I can provide it if you need it.

Think about it a little. With so many training points, how come only a few people have passed the certification? This list includes my teachers. My former company spent more than 1000 yuan to let me attend a training that doesn't exist? I graduated from Shanghai Jiaotong University and trained in Shanghai Mold Design Institute. I think UGS should be on the list. Shanghai Mould Design Institute itself is an affiliated research institute of School of Mechanical Engineering, Shanghai Jiaotong University.

In addition, to correct you: TTTT's full name is Train The Trainer Training, which means "training trainers" in Chinese. It's awkward, but it's not the international advanced lecturer certification you mentioned. At present, there is no corresponding certification in any official organization, but these certifications are evaluated by international reviews conducted by international companies, and they are mutually recognized within these companies, which is exactly the same as 6 sigama certification. TTTT*** has four levels, and I only have three levels, which has nothing to do with advanced training. It can only show that I am qualified to be a senior trainer, not a pure qualification certification.

2.

"But I don't even understand the process ... it's too much."

You should be responsible for saying this, and at the same time you have introduced a big concept. What is DFMA?

/85/84438/drive.shtml

The full name of the graphics card is Leadtek NVIDIA GeForce Go 7400, which has been discontinued. But you have to check online, drivers are everywhere, and the above is just one of them.

Sorry, I provided an expired information. Not all products, especially discontinued products, will be listed in official website. For example, Sony has numerous products, but how many products can be listed on its home page?

Also, I admire the outstanding performance of Wildcat 4. If you tell me how to sell this kind of graphics card, the graphics card of Wildcat 4 is relatively old, and even now it is still 1.7 million.

7.

"Show or Link Part Assemblies by Hiding Layers":

Doesn't hiding in the layer take up system resources? Assembly is not for beauty. How to check the interference after assembling the linked parts?

If PDM software is used, how to cancel the parameters under PDM software management? Even without the management of PDM software, single-machine operation and parameter elimination will make parametric design meaningless, so it is better to go back to autocad.

8.

Alias is not a very biased design software. At present, some processing precision equipment manufacturers in Shanghai are already using it, and the domestic usage is also increasing. I dare not say that I am proficient in this software. I haven't studied it for a long time. I just learned a little for training.

As for foreign languages, this is just a tool. There are many mechanical engineers who know three foreign languages in Shanghai, and I feel inferior in this respect.

Not to mention the following, writing this is more tiring than making a demonstration. I believe I will see you again!

Finally, to bengok:

"Speaking of which, we have digressed a lot. I suggest posting this post last, because I don't think we can completely convince each other after four days. Different circumstances caused our argument. No one is right or wrong. As far as pure software is concerned, I have exaggerated, and so has myth2000. UG and pro/e are generally excellent software, while UG is relatively general and comprehensive in all aspects, pro/e.

Specializing in modeling, if you want to choose, it depends on which software you use more conveniently or simply draw lots, because some advanced functions of the two softwares may never be used, and you don't have to compete for some functions that may never be used like the two of us. "

If you had communicated with each other earlier with such an attitude, I'm afraid there wouldn't be so much nonsense above. I'm at the airport now, and I'm going to Spain in two hours, so I can't continue to discuss with you for the next four days. Although there are still many problems with the above things, they are basically acceptable to everyone, so I won't say much.

Finally, I want to share an experience with you:

"I said above that you are not close to the grassroots, because many of what you said above are concepts and standards. These systems are not clear to people who have received professional mechanical training. Needless to say, a novice who has just stepped into the machinery industry, for us, a process can be as simple as possible, and we will not do complicated ones. If we can do a process within 5 lines, we won't do it within 1 line with 3 processes. Nowadays, the processing status in Chinese mainland is cost saving. There are no high-end products, and some people do it, but a big premise is cost! Because the market decides everything, all we can do is to reduce the cost and not import high-precision machine tools.

But please don't look down on the domestic processing industry. Everything you buy can be picked out, and there is no shadow made in China. When you come to Qingdao, I'll treat you to Tsingtao beer! "

Because I was touched by your words. I think you have discovered that I can speak Japanese besides English, and you should also wonder why I am so familiar with the equipment in Amada. As a matter of fact, I was sent to work in Japan as soon as I graduated from college. My two years working in Japan have taught me a lot. Brother, the gap between us and others ... we call it anti-Japanese, but we ignore the gap between us. The straightness tolerance of Amada sheet metal equipment is 0.0 1, the bending equipment is 0.09, and the basic error of numerical control can be 0! The molding error of Funac's injection molding machine is 0. 1 ... too much. How many domestic suppliers can do it?

In my first year there, I did sheet metal, machining, molding and painting, many of which were front-line jobs. But the Japanese always said to me before asking me to do this: this is not your job, but you need to know, so now you must do it. This is a rotation training, it is temporary. At that time, I also wanted to learn NC programming. Actually, I studied it in college, but the boss made it very clear that this is not your job and you won't use it in the future. There is no need to understand. In fact, I am very grateful for my life that year. I can throw out an accurate drawing today, and I guarantee that all drawings that can be processed depend on that experience. So I think my knowledge of machining and assembly, as well as material properties, are beyond my peers.

Tell me a real example. I drew a round hole with a diameter of 26 on the picture, and my boss scolded me 1 hour. Do you know why? Because there is no knife die with a diameter of 26 in the market at all, if I really want to do it according to my drawings, there are only two ways, either to make a small round knife with N knives or to open a new punching die. I think you are clear about these two costs. So you said that I am not close to the grassroots, which is more difficult for me to accept.

Speaking of Made in China, it makes me feel ashamed. Do you know how many products are called Made in China? Open the equipment, except the sheet metal parts, everything else is completely imported. There are two cabinets in my lab. Even a primary school student can tell which one is imported and which one is made in China in a few seconds. You should know that things made in China are cheaper abroad than at home. For another example, I designed a component with a thickness of 1.5 the day before yesterday, but the ipo can't find a standard material with a thickness of 1.5 in the whole of East China and South China, including Baosteel, only 1.45, and the best one can only be found in t 1.46. Unless you order, you must buy imported materials from Japan. As a native of China, I am ashamed.

To be fair, I really look down on the domestic processing industry. Every time I choose a supplier, I will not consider domestic suppliers. Maybe I'm biased, but this is definitely not my personal problem.

I work for Americans now because of the pressure of life, especially because of my five-figure monthly income, but if one day our domestic generals

When the technical level reaches or is only close to the world level, I will go to work at any time as long as a local company wants me.

Bengok, I go to Yantai, Qingdao several times a year, hoping to have a good exchange. Qingdao is a good place.

Landlord, please let this post flow and don't waste so much on each of us.
