What are the main things to pay attention to when learning CAD?

CAD precautions.

When it comes to CAD drawing, it's easy to get started and hard to master, because it only makes sense when it comes to practical applications. Of course, if you're just an amateur and just a happy draftsman, that's not the case.

But there is nothing more to be aware of for beginners.

1. Basic knowledge, CAD functions are still very complete.

2. Step by step, from shallow to deep, don't want to draw some big works at the beginning, draw lines and simple graphics well.

3. It is best to draw according to the actual needs, what to draw today is drawn step by step, draw slowly, and after the painting is completed, you will be familiar with many functions.

4. After that, there are some common problems in the accumulation of answers to drawing skills, and there will definitely be various situations in the process of drawing, even if you draw a direct one, some people draw like a dotted line, that is the reason for the proportion of the line.

Then the knowledge of the label class needs to be supplemented, the layer knowledge needs to be supplemented, and the block knowledge needs to be supplemented.

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.

2. Open the CAD software and 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. There is a black triangle behind some functions, and there is also a submenu of many tool function options at the back.

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

1. CAD is computer-aided design. Since you are designing with a computer, the basic computer usage foundation is a necessary skill.

3. Design foundation. Due to the high cost of engineering construction facilities, it is impossible for Luchang to test and lay out the final effect scene with real objects in reality, so it is necessary to use the computer to express human creativity on the computer in a three-dimensional way according to the actual scene data, so as to facilitate everyone to communicate and establish the clearability of the final plan, so there is a computer-aided cavity design technology.

4. Know how to quickly hand-draw performance. In this way, when the customer puts forward the demand, it can be quickly expressed with hand-drawn sketches, which is convenient for the customer to communicate with the customer on-site to understand their real needs, which can not only improve work efficiency and reduce unnecessary trouble in CAD design, but also understand the customer's needs thoroughly and save the construction cycle.

Beginners in CAD drawing should choose the right drawing tools, determine their own learning style, master the basic knowledge of CAD, learn to read drawings, etc.

1. Preparation of appropriate 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

Choose self-study or enroll in a class, if it is self-study, then ** teaching is the most effective method for any teaching, even if there is no foundation, once again** down, the basic concepts and knowledge points, look at the operation.

3. Master the basic knowledge of CAD

1) Familiarize yourself with a few common commands.

2) Start with simple straight lines, copy and other commands.

3) Gradually start with slightly difficult patterns such as flowers.

4) 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 of course, you also need the geometric knowledge of Yiqin Liqinding.
