What self learners need to know about CAD

1. The version of AutoCAD is not too high, 2007 is enough, the operation interface of the too high version has changed, it is not universal, and pay attention to save it in 04 format when saving, otherwise it will not be printed.

2. It's not worth it to go to class for CAD, and you can paint this thing for a week. Buy this book, to be good, I was using Tsinghua University Press's AutoCAD 2000 Introduction and Improvement, Now I don't know how much the latest version is CAD, probably AutoCAD 2007 Introduction and Improvement In short, you still buy this set, the branch factory mentioned in the book is detailed, and not verbose, Use it to know, 3, three things to be clear: 1 must be able to divide the layer Whether you are architecture, planning or interior, people who do not divide the layer will be very troublesome later, and others will not be able to take over your drawing, So there must be the concept of sub-layer 2 Cancel your right-click shortcut menu, the specific method is very clear, after canceling, right-click is OK, combined with the left-handed shortcut key operation, so that it is faster than you only use the mouse to click to click, 3 Be sure to use shortcut keys, there are a bunch of shortcut lists on the Internet, Don't remember them all, you can write down the commonly used ones, straight line, delete, **, fill, chamfer, ......CAD is the manual work in the back, and the shortcut keys will help you save time and effort to complete the drawing work.

4. Practice more, CAD is a physical work, only familiar with the hands, you practice more, you will naturally be proficient

First, the use of commands, more use commands to draw, all the displayed commands are: z space a space, to use more.

3. The most important thing: learn according to the command prompts and get twice the result with half the effort! CAD This software is human-computer interactive software, that is to say, people give commands, tell CAD what to draw or what to do, and then CAD will feedback information to people, and people will operate according to the command prompts!

Fourth, the commands for modifying and drawing toolbars must all be mastered proficiently!

The foundation is very important, step by step, practice makes perfect.

First, the foundation is very important

Practice has proved that the "manual drawing board" drawing ability is the basis of computer drawing ability, learning "AutoCAD", need a certain amount of drawing geometry knowledge and ability, need a certain ability to recognize the map, especially the ability to make geometric drawing, generally speaking, people with a high level of manual drawing, it is easier to learn, the effect is better.

Second, step by step

The whole learning process should be done in a step-by-step way, first understand the basic knowledge of computer graphics, such as relative Cartesian coordinates and relative polar coordinates, so that you can master the use of AutoCAD technology from shallow to deep, from simple to complex.

3. Apply what you have learned

When learning AutoCAD commands, always combine them with practical application, and don't spend the main energy on learning each command in isolation; The principle of applying what you have learned runs through the whole learning process, so that you have a deep and vivid understanding of drawing commands, which is conducive to cultivating your ability to use AutoCAD to complete drawings independently.

Fourth, practice makes perfect

You should force yourself to make a few comprehensive examples, and draw the graph in detail, so that you can grasp the whole drawing process from a global perspective.

CAD can be self-taught.

The basic operation of self-learning CAD generally only takes 2 to 3 months. Those who learn CAD need to learn professional drawing knowledge at the same time, such as mechanical drawing, and need to master the three-view and projection rules, various mechanical drawing specifications and methods, as well as roughness, tolerance fit and other professional knowledge.

Self-taught CAD skills:

1. First of all, it is necessary to understand the meaning of CAD clearly, CAD is a drawing tool, and CAD can be used to draw design drawings. Learning design is not difficult to say, it is not easy to say that it is easy, it is important to cultivate interest in learning, and it is best to take a small test before learning.

2. The second is to think through the internal tools of CAD software, what tools are useful, and the tools can be understood clearly to facilitate the later learning to be easier to understand and get started.

3. Learn on CAD teaching, you must learn and operate, don't just look at the theoretical knowledge, you must operate it, only by doing it, you will have a deeper impression.

4. According to the teacher's guidance, start drawing with some simple ones, such as straight lines, rounded corners, annotations, filling, etc.

5. Learn to improve work efficiency with the help of plug-ins, etc., and the plug-ins are used as royal model brothers, which greatly shorten the working time when drawing drawings. <>

<>2. Then open this software and you can see that there is a lot of content in it, and the next thing to do is to understand these functions, and be familiar with their location, function and use. It is best to buy a book comparison exercise for this CAD.

3. Menu bar, toolbar, drawing tools, let's take a look at the menu bar are some general names like "file", "drawing", etc., every time you click on it, a drop-down menu will appear, you can click to try, if you don't understand it, there is a help in it, you can take a look.

4. Next, click on the file, you can see that there are many options in it, "New", "Open", "Save", etc., which are all in the file, and you can also write shortcut keys, so that the drawing speed will be greatly improved.

5. There is a black triangle behind some functions, which means that there are other tools behind it, and it will appear after clicking on it, the first thing to do is to memorize the location of these functions and the corresponding shortcut keys, and what to use when making drawings in the future can be found directly, if you can't remember it, write it down for easy viewing.

6. There are also often encountered is the drawing and annotation tools, the drawing can be seen directly on the desktop, the annotation can also be placed outside like the drawing, you can click on the blank space of the drawing tool will pop up a menu, and there is a label on the top Click will appear on the desktop.

7. In this tool, they all appear in the style of shapes, some of them are like those straight lines in the drawing, what are the circles, and we can see them directly, and it is not easy to understand these marks, it doesn't matter, there is also a mark in the menu bar, click on the corresponding name in the drop-down to remember it.
