I didn t know anything about CAD, but I wanted to learn where to start

CAD (Computer Assistant Design).

An important indicator of a country's scientific and technological modernization and industrial modernization.

It is widely used in the fields of mechanical engineering and construction engineering, and is also widely used in the field of environmental engineering.

CAD drawing has many advantages over traditional drawing boards.

CAD Drawing Design Methods CAD software applications.

The necessary conditions for designers to draw CAD drawings: master environmental engineering design methods; Proficient in CAD software.

CAD drawings are the language of engineers.

The design department uses drawings to express design ideas and design intentions, and the production department uses drawings to guide processing and manufacturing.

The use of departmental drawings as the basis for the preparation of tender documents, or for use and maintenance.

The construction department should apply the drawings to prepare the construction organization plan, prepare the bidding ** and prepare the materials, and organize the construction.

Any engineering technician and management personnel in the field of construction engineering are required to have a certain ability to read drawings and draw drawings, and if they can't read drawings, they are like illiterate and cannot be competent for their work.

In order to implement the national construction norms, civil engineering professionals require the length, house height, doors, windows, stairs and other dimensions of the plant to obey the provisions of the modular system.

Personnel engaged in environmental engineering have the knowledge of civil engineering CAD drawing, so as to better carry out process design.

Have a common language with civil engineering professionals.

Works well with other professionals.

Put forward requirements for civil work and supervise it.

At the same time, it can carry out simple civil design by itself, so that the reasonable process content and perfect art form can be combined.

Give full play to creativity and spatial imagination, be creative and innovative, and make the process design better.

Find a simple mechanical drawing, draw it with CAD according to it, and soon you can get started when you encounter a manual that you can't see!

Beginners start with basic shortcuts and drawing recognition.

The first thing to learn is of course the most basic drawing recognition, and then open CAD and learn basic general commands! For example, choose a background color, create a layer, create a font, toolbar, set the line type scale, set the size scale, and more! Then you're ready to start drawing!

The following learning steps can be installed for specific learning methods:

1.Create a layer, a template file.

2.Looks at the command line, which is a must unless you memorize the steps for each tool.

3.Proficient in the use of tools, drawing software tools and modification management tools, it is best to remember the shortcut keys, and the following shares some commonly used CAD command shortcuts:

l=straight line; pl=polyline; uEnter=Ctrl+Z=Backward; d=modify, adjust; rec=rectangle; c=circle; tr=trim;

o=offset; XL = radiation; x=decomposition; co=copy; m=move; mi=mirror; el=ellipse; br=interrupt;

pol=polygon; len=elongated; s=stretch; me = aliquot; e=delete; eEnterallEnter=Delete all; ar=array;

2. Open the CAD software and you can see that there is a lot of content in it, and the next thing we need to do is to understand these functions and be familiar with their location and functions.

3. In the previous step, the arrow marked the menu bar, toolbar, drawing tools, let's take a look at the menu bar are some general names like "file", "cartography", etc., we will appear every time we click a drop-down menu can click to try.

4. Click on the file, and the options "New" and "Open" will appear, etc., followed by shortcut keys, which are also very useful if you can remember.

5. Some functions have a black triangle behind them, and there are also submenus with many tool function options at the back.

6. Drawing and annotation tools, we can see the drawing directly on the desktop, click on the blank space of the drawing tool to pop up the menu, click on the top of the annotation, after checking, it will appear on the desktop.

1. Preparation of appropriate drawing tools.

Drawing tools: complex drawing operations, in the selection of tools must be simple, convenient, simple and simple, the professional version of the quick cad, it is very good, compatible with all the functions of AutoCAD, novices can quickly get started with drawing, all kinds of villas, landscapes, machinery are used.

2. Determine your own learning style.

Because of the zero foundation, it is best to start with the basics first, and then then transition to the higher level of mastery. Self-study** as well as professional CAD websites are available.

3. Master the basic knowledge of CAD.

Let's familiarize yourself with a few common commands. Start with simple commands such as drawing a straight line, copying, etc. Gradually start with slightly more difficult patterns such as flowers. Copy a set of construction drawings.

4. Learn to read pictures.

If you want to be proficient in CAD drawing design, you must know how to understand CAD drawings, you need to know the annotation and size of a set of drawing files, and you also need a certain amount of geometric knowledge.

1. Preparation of appropriate drawing tools.

What is the right tool?

Many people have a mysterious pursuit of the professionalism of AutoCAD drawing tools, in fact, there is no need, it is suitable for their own use! There are two tools to share here, and beginner learners can choose according to their own situation.

Drawing tools. Complex drawing operation, in the selection of tools must be simple, convenient, simple and simple, the professional version of the fast cad, it is very good, compatible with all the functions of AutoCAD, novices can quickly get started with drawing, all kinds of villas, landscapes, machinery are used.

2. Determine your own learning style.

3. Master the basic knowledge of CAD.

4. Learn to read pictures.

If you want to be proficient in CAD drawing design, you must know how to read CAD drawings, you need to know the annotation and size of a set of drawing files, and of course, you also need a certain amount of geometric knowledge, how to obtain this knowledge? Choose a professional CAD book and learn to read pictures.

I once taught CAD to someone who had no foundation. To sum up, the following points can be summarized, and according to these points, I believe that friends can get started quickly and even become proficient.

1. Familiarize yourself with a few common CAD commands.

2. Start with simple command such as drawing a straight line and copying.

3. Gradually start the basic plane pattern with a little difficulty.

4. Let him copy one or two sets of construction drawings. Half a month to a month to get familiar with it, and then practice often and do more consolidation.

CAD itself is just a tool, and many questions should have been mentioned, but the first thing to understand is what you are using CAD for. As for how to get started, the current version of CAD basically does not need to buy a book from scratch, and 80% of the content of the book is just a simple translation of help documents and operation guides. Hover over any of the commands and there will be instructions.

For files, the most important thing is layer management, and for the pursuit of speed, the most important thing is to use shortcut commands and modify shortcut commands by yourself, and give up using the mouse to find commands on the toolbar.

Learning CAD drawing should be learned from the commands, shortcuts and operation methods of the software, and it is best to choose a reliable training class to learn.

If you want to learn CAD well, it is not difficult, the most important thing is whether you have the determination, you might as well use 60 seconds to test the click test whether I am suitable for learning design.

AutoCAD design is a time-consuming thing, it takes a lot of patience to draw, all kinds of shortcut keys, skills you must remember a lot, in fact, you can be faster, many gods like to use plug-ins when drawing operations!

CAD will be updated every year, so it is best to choose the latest version to learn, CAD has common shortcut keys, can be directly searched on the Internet and copied in the book, the use of more convenient operation, simpler.

No matter what kind of tutorial you learn, the mode of three days of fishing and two days of drying nets is definitely not possible, no one can reach the sky in one step, only unremitting efforts can achieve greater success.

The foundation is very important, practice has proved that the "manual drawing board" drawing ability is the basis of computer drawing ability, learning CAD, need a certain knowledge and ability of drawing geometry, need a certain ability to read the map, especially the ability to make geometric drawing, generally speaking, people with a high level of manual drawing, it is easier to learn, and the effect is better.

It is recommended to read some relevant tutorials on the Internet first, have a general understanding of CAD drawing, and then buy relevant books for systematic learning, and at the same time find some materials for practice, as well as see more successful works, learn more and imitate, you will definitely learn.

It is recommended that beginners buy a CAD basic book first, start learning, and be sure to buy this book to learn. Because the knowledge points in the book are more systematic and comprehensive, this can shorten the learning time. There was a lot of free information on the Internet, but it couldn't be compared to professional books at that time.

Buy a book that suits you, and by the time you've finished reading the book, you'll be almost ready to get started.

The next latest version of CAD2012 (remember to be the same number of bits as your operating system),It may be a bit troublesome to install,You can learn by yourself after cracking it with a keygen.。

Novices start from simply drawing straight lines, arcs, and multiple broken lines, and the next CAD command encyclopedia, (pay attention to the command prompt line when operating).

After becoming proficient, you will learn 2D operation, 3D modeling, solid drawing, and so on.

There are many functions of CAD drawing, and drawing is quite accurate and standard, but it is also relatively regular to learn (you only know these when you try them yourself).

Tianhu is good bai like a professional design.

Du trained, is a zhi

Listed training institutions come to the DAO, and can quickly take up the post with efficient training versions. The teachers are full-time lecturers, with many years of design work experience and teaching experience, have participated in the design or competition of many large-scale projects, and will impart personal work experience and skills in the process of teaching.

It can also be used as a teaching material for vocational training and vocational education.

CAD is from.

An automatic computer-aided design software produced by Autodesk Active Co., Ltd. in the United States can be used to draw two-dimensional drawings and basic three-dimensional designs, through which it can be automatically drawn without knowing how to program, so it is widely used in the world, and is currently widely used in interior design, civil engineering, industrial drawing, engineering drawing, electronic industry, clothing processing and other fields.

If you want to engage in the career of CAD-related personnel, in addition to being proficient in the use of CAD operating system, you must also have a considerable experience and professional theoretical knowledge, but because CAD is widely used, our students should determine the direction of their own learning and research before learning activities. For example, if you want to engage in interior design related work, we need to learn the content CAD software operation, construction flow chart drawing, etc. at the same time, and also need to learn more knowledge and interior design, such as hand-drawn performance, style, interior design and other aspects of performance, so it is necessary for professional training institutions to learn.

Landlord, hello Fu.

To learn CAD, first of all, you have to install CAD on the computer, don't look at this, many novices will not, of course, it is a piece of cake for me to engage in structural design here, and I soak in CAD every day to draw drawings. Then it's to look at other people's pictures, such as what you want to draw, just ask others to the corresponding drawings, follow the drawing, don't understand to ask, it's easy to get started, you don't have to look at the kind of dozens of g tutorials on the Internet, what tutorials are not as good as people to teach you, if no one teaches you, you can contact me, at least you can take you into the beginning, I hope it will help you, I hope to adopt.

Buy a CAD exercise book, follow the book step by step, draw a few more times and you're ready to go. The CAD2004 version is the best ,..Then follow the tutorial step by step to start learning. I learned it in 2006 and bought a CD by myself and made it using the above method.

Will mechanical drawing do? What about math? Just for the sake of the software, we start with two-dimensional commands and memorize the role of each command. Just use the command a few more times, click on each command and there will be a hint in the command bar on what to do next, and you will use it.
