Three-dimensional mechanical software PROE, CATIA, UG, Solidworks, etc. What are their differences, professional fields, advantages and disadvantages?

Why do some companies explicitly ask employees what 3D software they will use when recruiting? What fields are these three-dimensional softwares currently used in, and what are their characteristics? I hope experts can point out 1, 2. Supplement: Personally, I think PROE is more powerful in rendering, motion simulation and sheet metal. CATIA is widely used in automobiles and aerospace, UG is mostly used in numerical control, and some programs such as powershape combined with powermill are particularly powerful. mastcam is more powerful in sheet metal development, right? I hope the experts can point out their advantages and disadvantages. I am very satisfied with the answer. Enthusiastic friends please call 20 1 1-03-06. Now many people on the Internet ask such questions. Let me give you a general idea. At present, there are these (and possibly other) industrial design softwares, PowerSHAPE and PowerMill. Rhinoceros, Catia, Maya, pro/e, Solidworks, MastCAM, UG, 3D MAX, Alias, Autocad, Lightscape, LightWave, Softimage and Cinema 4D all have their own advantages and disadvantages. It is suggested that UG, Solidworks and PowerSHAPE are better with the same major. Although the modeling methods are similar, the mixed use of software will affect the proficiency of operating software. PowerSHAPE and PowerMill are quite powerful in NC programming. From all aspects, PowerMill is the big brother in the field of NC programming today. It seems that PowerMill became a hit in the last NC contest. PROE, CATIA, I render it well, but it's not easy to get started. I don't want to say that I made a small achievement in a few years. Relatively speaking, UG, Solidworks and PowerSHAPE are relatively easy to learn. I just transferred from PROE to UG. I think some aspects of PROE are too complicated, or it may be because I am not proficient in my studies. Personally, I think the original intention of the company to restrict 3D software is to facilitate drawing, save conversion and facilitate modification. I hope it will help you: Thank you 20 1 1-03-08 Other answers (1)D.j9 Grade 20 1 1-03-06 Metalworking in various fields: It can be said that you can answer: What do you ask? Q: If you insist, you can only say that you are an amateur. A: Motion simulation is used to simulate the motion of moving parts, which belongs to CAE module in UG. I really don't understand. Know something about 3D modeling and NC machining module.
