Pay more attention to the orientation when looking at the picture, and it will look good if you distinguish the orientation. Generally divided into main view, top view and left view. In short, if you watch too much, you will turn back. Practice makes perfect. Ask if you don't understand! ! You should read more legends, which will help you understand this view. You can't rush to look at the picture slowly, you can do it with the parts facing the drawing slowly, and you can master it in two or three days! Of course, we should also look at the theoretical basis of cartography! Distinguish the front view, top view and left view, and then understand the sectional view. Can be combined with physical reference, can cultivate their sense of space. Look for some complicated drawings, and look at the reference objects that you can't understand first. Look at all the lines. It is best to pay attention to some benchmarks from the direction of the title bar. I also study mechanics. But I also think we should try our best to understand the drawing information. For example, there are many specific standards on it. I wonder what level of novice the landlord is. At different stages, different industries have different requirements [s: 1 1]. Theory plus practice is the best. For those who have not been exposed to mechanical drawing, it is best to practice drawing in combination with physical objects and ask the people around them about machinery. Furthermore, learn more about the standards and methods of mechanical drawing, and it is best to actually draw the drawings you have seen. Repeated and accumulated for a long time, it will definitely improve. Good luck! As a systematic study, we must first lay a good foundation. If the foundation is not well laid, it will be difficult to improve it in the future. Learn descriptive geometry first, and then look at some simple part drawings from shallow to deep! First of all, look at the picture number and name clearly and see your own understanding. Pictures are generally divided into three views (left view, top view, front view and sometimes cross section). When looking at a picture, you should first look at the front view, and then determine the object from the left view and the top view (some data are unified, learn to look at the corresponding relationship of the three views, and cultivate more three-dimensional sense. Look at the dimensioning relationship more and check the dimensioning correspondence more. Three in each row try to correspond. The three lines of each part correspond as much as possible. The length, width and height of the three attempts correspond to the whole entity. Only by practicing more can we understand the positional relationship between the three views well, and then associate them with the entity diagram. You should also pay attention to the plane lines. Lines with different angles represent different parts, so you should be able to distinguish them clearly. First, distinguish the front view, top view and left view clearly, and then refer to the sectional view in combination with the physical object, which is very useful for cultivating your sense of space. Learn to see the correspondence between the three views and cultivate a three-dimensional sense. Look at the dimensioning relationship more and check the dimensioning correspondence more. Three in each row try to correspond. The three lines of each part correspond as much as possible. The length, width and height of the three tests correspond to the whole entity, so it is recommended to buy a CAD textbook. If you can draw some pictures by hand, draw them yourself. When looking at pictures, try to understand what each line in each picture means. Just look at a few more pictures and see clearly the direction of the views, such as front view, left view, top view, right view, bottom view and back view. Read more books in full, half, partial and directional parts. If you look at it in combination with the perspective view, you should first look at the front view, top view and left view in combination with three directions, and you can refer to it in combination with the real thing. Practice makes perfect! Premise: have a certain descriptive geometry foundation, otherwise you can only know the picture but not the picture. 1. Look at the title bar first to find out what kind of parts (shaft sleeve, disk cover, fork frame or shell) are shown in the drawing, what material is it, what is the drawing scale, whether it is a casting, etc. 2. Starting from the front view, check whether the expression used in each view is an outline view or a section view. If it is a sectional view, where is the cutting position? 3. Understand the main points expressed by each viewpoint. For example, the front view adopts full section, that is to say, the key point is to express the internal structure; Local sections are used in the top view to express internal structures and local shapes that are not reflected in other views. 4. Combined with dimensioning, the parts shown in the drawing are wrongly divided into several basic shapes (cylinder, cone, sphere, plane solid) or several parts. Find out the shape and size of each basic body, find out the combination form between basic bodies, and combine them to think of the overall shape. 5. When looking at drawings, several views need to be linked, and a single view cannot fully express the structure of parts. 6. Read more parts drawings, think more about space shapes and communicate more. First look at the front view, establish the basic model, and then use the projection relationship between views to find the detailed features and practice more. It can be combined with physical reference, pay attention to dimensioning, and strongly agree with the view of 3 1 floor. I studied marketing at gffgbnfgbnfgnfnfnfnd, and worked in chemical machinery factory for half a year. I can basically understand the drawings. I think practice makes perfect, because I found that our vice president looks at the drawings very well, but he just graduated from primary school! I just learned 1. I used to be taught by a teacher, but now I have to rely on myself. Thank you for your valuable advice. Have you studied mechanical drawing? If you have learned it, it should be very beautiful. If you haven't learned it, you'll be in trouble. Theory plus practice, alignment, flatness, width should have a sense of space. Of course, it has to be simple before complicated. Don't try to eat a big fat man. That's just the opposite. You can't get familiar with the picture in a hurry. You can read everyone's opinions perfectly. I learned a lot. I'm a novice, too. I must have a strong three-dimensional sense in hard training. According to the drawings, think more about what the three-dimensional shape should be like. Look at more pictures. Practice makes perfect. Understanding drawings is only one aspect, and there is also the significance of marking codes. Practice makes perfect, practice makes perfect, practice more 1. In the lower right corner of the drawing frame, the general standard drawing will include material, product or process name, proportion, surface treatment, tolerance requirements, designer, reviewer, projection method and so on. 2. Looking at the view of the product, the general draftsman will divide the product into several views, namely: top view, bottom view, front view, back view, left view, right view, auxiliary view, enlarged view, global sectional view and partial sectional view. The number of views depends on the requirements of the product. The placement of the view depends on the drawing method of the view. Generally, the third angle drawing method is adopted, because it is easier to understand and read the products on the drawings. 3. Look at the size and tolerance of the product. Tolerance is often used in machinery, electronics, chemistry, physics and other fields. Tolerance control is directly related to product quality and production level. Mechanical drawing is a subject that accurately expresses the structural shape, size, working principle and technical requirements of machinery with drawings. Drawings are composed of figures, symbols, words and numbers. They are technical documents that express design intentions and manufacturing requirements and exchange experiences. They are often called engineering languages. Patterns generally need to be depicted as transparent base maps, and blueprints are developed with transparent base maps or purple pictures are smoked with ammonia water. In the mid-20th century, an electrostatic copier appeared, which can directly copy the original image, enlarge or reduce it. This new technology can save the drawing process. There is no shortcut, just look more. If you are interested, you will soon understand. There should be a three-dimensional model of the back of your head. What needs to be understood slowly cannot be understood at once. I think it's more important to look at drawings or something. It is best to learn quickly by comparison. It's really not good to buckle one with potatoes. Hehe, really, I've seen someone use it.
