It's a two-dimensional drawing software, this software will be used in many places, such as mechanical work, electrical work, etc., will use this software, so you can learn to learn.

Hello. CAD is mechanical drawing software:

You can enter the drawing after the computer end, especially in the field of mechanical design, which will be used more, of course, there are students majoring in mechanical engineering who want to install and learn. Hope.

CAD is a design software that needs to be used in many places.

For example, let's say your computer monitor, length*width*height*thickness.

After designing on it, we have to make a mold for the factory!

It's not easy to type, hopefully, please, please.

What software is available for CAD.

There are many kinds of CAD software, it is a general term for computer-aided design software, and some people use it to refer specifically to AutoCAD software. Commonly used CAD software is AutoCAD, Creo, SolidWorks, UG, CATIA, IDEAS, etc. At present, there are many kinds of CAD software on the market, and the above list is some mainstream software.

Can you tell us more about that?

CAD is a powerful computer-aided design software, which has been widely used in various industries. It helps designers with drawing, analysis, budgeting, storage, and more. According to different professional fields, there are many brands of CAD products that have been redeveloped, such as Tianzheng, Tianyu, Explorer, etc., which are mainly used in structural engineering CAD, sheet metal CAD, clothing CAD, HVAC CAD, mechanical CAD, electrical CAD, chemical CAD and so on.

CAD stands for Computer Aided Design. It is currently the most popular auxiliary drawing software system in China, which is widely used in civil engineering, decoration, urban planning, garden design, electronic circuits, mechanical design, clothing, shoes and hats, aerospace, light industry and chemical industry.

Application areas of CAD:

Engineering drawing: architectural engineering, decoration design, environmental art design, hydropower engineering, civil construction, etc.

Industrial drawing: precision parts, molds, equipment, etc.

Garment processing: garment plate making.

Electronics industry: printed circuit board design.

And then add: planning, as well as gardens, landscapes.

First, the concept of CAD software

Computer aided design refers to the use of computers and their graphics devices to help designers carry out design work. Designers usually start with sketches, and the heavy work of turning sketches into working drawings can be handed over to the computer; The design results automatically generated by the computer can quickly make graphics, so that the designer can make judgments and modifications to the design in time; The computer can be used to process the graphics data related to the graphics, zooming in, zooming out, translation, copying and rotating.

Second, the development history of CAD software.

China's CAD technology originated from the secondary development of foreign CAD platform technology, with the improvement of Chinese enterprises' demand for CAD applications, many domestic CAD technology developers have developed secondary development products based on foreign platform software to make domestic enterprises truly popularize CAD, and gradually emerge a number of truly excellent CAD developers.

On the basis of secondary development, some of the top domestic CAD developers have gradually explored CAD suitable for China's development and demand model, such as Haochen CAD is more in line with the usage habits of domestic enterprises, and its purpose is to develop the best CAD, and even provide the best CAD technology for the world.

Third, the use of CAD software.

Engineering drawing: architectural engineering, decoration design, environmental art design, hydropower engineering, civil construction, etc.

Industrial drawing: precision parts, molds, equipment, etc.

Garment processing: garment plate making.

Electronics industry: printed circuit board design.

It is widely used in civil engineering, decoration, urban planning, garden design, electronic circuits, mechanical design, clothing, shoes and hats, aerospace, light industry and chemical industry.

Fourth, domestic CAD innovation function.

In CAD design, the most common thing to deal with is drawings, whether the drawings can be displayed quickly and accurately has a very significant impact on the user experience of CAD software.

Domestic CAD with their understanding of users,Gradually developed more practical innovative functions in CAD design,Haochen CAD contains hundreds of extension tools,Such as CAD** and Excel conversion、Drawing comparison、Efficient functions such as blocks。 In addition, Haochen CAD innovates and develops collaborative design system, which is the only CAD collaborative design system in the world, which integrates design and management to solve the problems of "difficult implementation of internal standards", "frequent modification of multi-person collaboration", "low efficiency of multi-professional collaboration", and realizes the transformation from improving single-point efficiency to improving overall efficiency.

Although everyone has always understood CAD as AutoCAD by default, CAD CAE is a general term, and their application scope includes almost all human industries.

Taking CAD software as an example, the two-dimensional ones include AutoCAD, and the three-dimensional ones include CATIA, CREO, UG, SOLIDWorks, and cloud map 3D.

With the development of the times and technology, the industry is now basically turning to 3D CAD, and most of the 3D CAD software is foreign, and the monopoly is particularly serious. However, Yuntu 3D has done a particularly good job, breaking the monopoly of foreign countries and making its own characteristics.

If a novice just starts to learn CAD drawing, it is recommended to use lightweight CAD software, starting from the most basic functions, such as Haochen CAD computer version software, which is a lightweight CAD software, with complete basic functions, if there is **unclear in the upper right corner of the interface to select help, you can click on customer service to directly have **customer service answers, you can also view the help document, as shown in the figure below:

CAD software has AutoCAD, Haochen CAD, Swift CAD, and electronic drawing board CAXA, I think it is also a kind of CAD, and many operations are exactly the same. AutoCAD seems to have some mechanical version or something.。。 Everyone uses AutoCAD for free, and I don't know what is charged.
