Compare the advantages and disadvantages of UG, CATIA, Pro / E, and SolidWorks?

A: SolidWorks is the simplest. Various operations comply with the operating habits of most people, and the functions meet the needs of most industrial design. It has a high degree of popularity and good inclusiveness. It does a good job in mutual import and export cooperation with other software, and simple rendering, simulation and mold design are easy to start.

The surface function of proe is stronger than that of SW, and its popularity is also slightly higher. However, it is uncomfortable to get used to the windows platform, which has been greatly improved after entering the era of wildfire. However, to realize the same function, the operation is still more cumbersome than that of SW. Generally speaking, the gap between the two software is not big. It's enough to learn either one. Moreover, if you want to learn the other one, you can basically achieve the same level of proficiency in one month. It's recommended to use which one you use most around the software. If there is no one around and learning from scratch, SW is better and will get started faster.

CATIA and the first two are not of the same order of magnitude. They are oriented to more professional applications and have incomparably powerful functions. If the first two are for ordinary civil products, the latter is also engaged in automobile design at the lowest level, more for aviation and ships. Of course, it is easy to design consumer goods. Domestic CATIA users are polarized. Some are real experts and master engineers, and some are running into the name of CATIA. Most of them stay at a level higher than the entry level and use CATIA to do SW work. If there is no foundation, it is suggested that you do not need to hurry to learn CATIA. If you are proficient SW and feel that it is not enough, you can contact CATIA again. This is not a waste. On the contrary, it may be easier to go deeper than learning CATIA directly.

B: First of all, I think it is of little significance to compare among several software. Each software has its own characteristics when used as a tool. Everyone's preferences and habits are different. It is difficult to have a more objective evaluation.

Secondly, as a tool, it is not better, only more suitable. That kind of application is more efficient. Therefore, it is suggested that the landlord should pay attention to these aspects for some understanding and research.

1. I have used several software and almost all 3D CAD software. UG from 16 to nx9, CATIA from V5R16 to R21. Proe from 2000 -- wildfire 4 solid works,solid edge,cocreat,inventor. 

2. For historical reasons, CATIA is used more in aviation and automobile. UG is widely used in the automotive industry, and Pro / E is more used in the home appliance industry. If you are in different industries, you may have to be familiar with these software.

3. As for the functions of each software, CATIA, UG and Pro / e all have different solutions, including efficiency, convenience and ease of learning. Some software seems to provide many options and complex functions, but its ease of use and mastery are reduced. For example, UG (only personal one-sided view), some software provide fewer options and provide sufficient solutions in a limited range of applications.

4. For software learning, I know that the more you study deeply, you will find that the more functions software can complete (nonsense). In fact, it also confirms my "tool" theory. Practice makes perfect. So I use different software on different occasions. When I encounter problems that need to be solved, I study the software, that is, the process of learning. From this process, I think proe > CATIA > UG But it's just a personal feeling.

5. Now the functions of CAD software tend to integrate and learn from each other, so one software has some functions, and the other software can solve them.

6. In terms of the running speed of the software itself, the same machine, the same operating system, Pro / E > CATIA > UG (personal feeling, no quantitative test)

C: I have used UG, Pro / E, SolidWorks and CATIA. Let's talk about our understanding from personal experience.

First of all, SolidWorks is the simplest and easy to use. Generally, small and medium-sized enterprises are using it, mainly because the training is simple and fast. There are many standardized modules, and other functions involved are relatively comprehensive. It can be rendered, analyzed and simulated, but they are not good.

Then there is Pro / e. the 3D software I first learned is Pro / e. the learning difficulty is good. There are many online tutorials in all aspects. Surface modeling is very powerful, simulation is a highlight, and parametric modeling is very convenient. Now it is renamed Creo, but it is still very popular, and many people are using it.

Next is UG. I'm mainly using UG now. The learning difficulty should be similar to that of Pro / E. however, after learning a three-dimensional software, others should bypass the analogy, so I don't think it's very difficult. I also grasp a lot of online tutorials. The surface modeling of UG is also very powerful, and the machining simulation and machining programming are also very convenient. Generally, it is not very complex to use UG for programming. In my opinion, UG has a great advantage, which is synchronous modeling, which makes the operator feel very convenient in the modeling process. Especially when modifying after modeling, there is no need to consider many parent-child relationships like Pro / E. I only use UG now, which is a large part of the reason. In terms of application, in the past few years, most of them used Pro / E to make plastic molds. Now the South has basically changed to UG, whether plastic molds or stamping molds. Personally, I am optimistic about UG and think it should be the mainstream in the future.

Finally, Caita. I haven't used it. I've only seen other people's operations. It's not very difficult to learn, but I can't use CATIA in my own work, so I didn't learn it. Personally, I think CATIA should be the most powerful of these software. Originally, this software was originally made for the design of aircraft, so the surface is almost against the sky. Now the surface of cars is becoming more and more high-end, so CATIA will also be used in the shape design of general cars. However, if I don't work in AVIC III or automobile, I don't think it's necessary to learn such high-end software, Because you probably won't use... And after mastering other three-dimensional software, if you really want to learn, it should also be very fast.

The above are some of my superficial views. If there is a great God to see it, I hope you can give me some advice.
