Laptops are recommended for running CATIA software capable of finite element analysis and other purp

The Core i7 3770K processor will do.

I am a Guangzhou notebook dealer, if you need flowers, you can add my QQ, I am satisfied with giving you an answer, you can not add if you don't need: 398149099

It's good to choose Dell, I use it with a lot of friends. The model depends on whether you want to play games or work, and the model configuration you choose is not the same for different needs. If you don't have a big budget, you can consider several books of the Inspiron M102Z series, there are several color options, and there is no problem with general office entertainment, **Generally between 3400-3800.

ThinkPad** is of relatively high quality and very classy, but it is very good. But now the ThinkPad also belongs to Lenovo! The Dell I use, the shape is okay, a little hotter.

CATIA is used more widely in the automotive shipbuilding industry (why I don't know).

UG is used in aerospace (because it does a better job of streamlining the surface).

Each has its own merits!!

The construction elements in the sketch are dashed lines, which are auxiliary lines and are not displayed when the sketch is generated. Lines drawn by standard elements can be displayed.

What kind of round-trip order? Is it a pre- and post-simulation reset command? It's still the thing that you take step by step when you simulate.

I know that the STP format is very convenient, you can directly transfer pictures to different versions of CATIA to each other, and save them in STP format, which is fast in one step, but STP format can't preview the file! Others are solved as well...

Dizzy, why are you deducting money again, depressed, waiting for an upgrade, hey。。。

Red Alert was not paying attention when posting on the forum and was stolen 2 gold by a thief.

Generative modeling, a very complete curve operation tool and the most basic surface construction tool, in addition to completing all curve operations, can complete stretching, rotation, sweeping, boundary filling, bridging, repair fragments, splicing, bumping, cropping, smoothing, projection and advanced projection, chamfering and other functions, continuity up to G2, generation of closed sheet volume, fully achieve the ordinary 3D CAD software surface modeling function, such as Pro E. Fully parameterized operation.

It is used when you need to draw spatial curves (spirals, etc.), lines, or surfaces.

Generative is what you can model according to your own needs.

The SW upstairs was developed on the basic framework of the PRO E.1 The development of the PRO E is relatively early At present, it is used more in machining and mold manufacturing (especially in Japanese and Taiwanese companies), and it is characterized by expertise in parametric design and surface modeling, but the disadvantage is that its operation is not very user-friendly.

2 UG is a collection of multiple software function itself powerful, since the acquisition by Siemens, its ability in the CAM is recognized by the industry, at present, more and more enterprises are using UG, from the number of courses in colleges and universities, it can be seen that the future of China's boss will be possible to replace PRO E by UG

3 SolidWorks and CATIA are both products of Dassault, a well-known French company, which is the relationship between the elder brother and the younger brother. CATIA is famous, the famous Airbus and Mirage fighter jets and the Bird's Nest in Beijing are all from CATIA and its surface modeling ability is the first, but it is also very laborious to learn, and the use is still relatively niche. As for SW, it is a modeling software launched by Dassault in order to seize the 3D software market for land, which is very in line with the market demand in terms of modeling speed and accessibility.

The functionality is very balanced, and the lack of surfaces in the old version is getting better and better with the speed at which a new version is rolled out every year. It is said that this year's sales volume in Taiwan SW (most of the foreign countries buy genuine copies) has already surpassed PRO E. In particular, SW is also a middleweight 3D software.

These four software can be divided into two categories, proe and sw are one category, which belongs to the category of always, with many users, while ug and catia are one category, which belong to the powerful but relatively high.

The advantage of UG and CATIA is that it is powerful and meets the needs of most enterprises, and the disadvantage is that it is difficult to learn, ** high, as long as it is used in large state-owned enterprises, UG's CAM function is well-known, and CATIA has a unique surface.

The advantages of PROE and SW are that they are easy to learn and use, and they are reasonable. In contrast, proe is more difficult to SW. The disadvantage is that it is not as good as UG and CATIA in curved surface modeling.

Both PROE and SW belong to the mainstream 3D software, and in terms of quantity, SW is far greater than PROE. It is mainly widely used in mold, sheet metal, machinery and other industries.

Engage in mold with PRO E, mechanical structure design with UG, automotive modeling CATIA, especially emphasize that UG five-axis processing is very powerful, SW is very powerful, but the amount used is very small, and it is not powerful. The first three are recognized as high-end design software.

Difference in use: UG is mostly used for mold design, product design, and programming processing. SOLIDWORKS is used for mechanical part design, sheet metal design.

Difference in installation difficulty: they are all more complicated, and it is difficult for novices to install them. However, you can use [UG One-click Installation Tool] and [SOLIDWORKS One-click Installation Tool] to solve the problem.

PRO E has a strong three-dimensional shape and is suitable for mold design.

UG is all powerful SW can be seen as a simplified version of UG and is suitable for modeling.

CATIA surface has a strong function, and many aircraft and car designs use this.

None of them are active.

The one on the left is disconnected from the process of doing it; Every step of the current state is with parameters, click this command to make the next operation without parameters (that is, it can not be modified after confirmation), and after double-clicking, it is the state of being active all the time, and the operations in the activated state are without parameters; This command is useful for points, lines, and polygons, but not for entities.

The command on the right is a display command, and the current state can be seen by doing it; After activation, you can only see the things in the current working object, and the data in other parts or bodies is as if it has not been done, and it cannot be found in the hidden.

The middle one has not been used.

Available in the part assembly environment
