Graphing skills 0 Three basic aspects of -AUTOCAD usage At present, our companys design documents, especially drawings, are drawn with AUTOCAD software. However, there are still a lot of people on CAD are not very familiar with, or use is not
2、 handy, so the efficiency is not very high, it can be said, in our company, draw a drawing the same, fast and slow in time may be a difference of several times. At the same time, everyone draw out the drawings do not feel the same look, some drawings look clear, clear and beautiful, and some drawing
3、s not only the expression is not clear, too much points can be used to describe too horrible to look at. From the beginning of the project design, I will be more than ten years experience as a serial bit by bit, for our people, hope to be helpful to everyone, from one or two to draw, to develop good
4、 habits, improve the speed of drawing drawing. At the same time, I also hope that this is a starting point, with this opportunity and carrier, we can make the use of CAD for an exchange and discussion, mutual improvement. In addition, because I am a construction professional, the other professional
5、understanding, therefore, the future examples will be mainly related to the construction profession, I hope we can draw inferences from others. I dont know. What do you think is the most important thing to use CAD to draw? It is possible for everyone to understand this question differently, but in m
6、y opinion, the most important thing is to always remember what the purpose of CAD drawing is. We carry on the engineering design, no matter what specialty and what stage, in fact, is to some design ideas or design content to express and reflect on the design document. The drawing is an intuitive, ac
7、curate, eye-catching and easy to communicate forms of expression. So we do something (whether the final design documents, or as a condition submitted to other professional files, need can help us express design ideas and their contents. With this premise, we should understand that a good computer dr
8、awing should have the following two features: clear and accurate. Clarity: what we have to express must be clear, and good drawings look clear. At first glance, you can tell which walls are, which are the windows, which are the holes, the pipes, the equipment, the dimensioning and the captions, etc.
9、, without overlapping. In addition to the printing of the drawings very clearly, the display on the monitor must also be clear. Besides the clear design idea and the design content, it is also the footstone to improve the drawing speed. Accurate: 200 width of the wall can not be painted 240; stay ho
10、les can not be marked on the size of 1000X2000, and the actual quantity is 1250X2100; more common mistake is clearly 3000 wide line, but the amount is 2999.87. Mapping is not only for good looking, but more importantly, it can visually reflect some of the problems on the surface, and also have an im
11、portant impact on improving the speed of drawing, especially when the drawings are modified. We use CAD drawing, should put these two points in mind every hour and moment. Only by doing these two things can we say that the drawing is basically through. The graph should be clear and accurate, and the
12、 same important point in the drawing process is efficient. Its good to be able to work efficiently. If everyone can improve the drawing efficiency by 20%, each project manager and the head of the room will probably not be able to smile. Clarity, accuracy and efficiency are three basic points for CAD
13、 software. In CAD software, in addition to some of the most basic drawing commands, and other editing commands, various settings definition, can be said to be around the clear, accurate, efficient three aspects of the choreography. We set the command, in learning CAD in all, had to think, they can p
14、lay the role in the three aspects; when in use should pay attention to what; and under what conditions, the most appropriate use of these commands. The first time you talk about these, the key is to every staff are aware of clear, accurate these two points of importance (efficient this point, we usu
15、ally get understanding, but also are trying to improve, and clear accurate, I usually have a lot of observation. My colleagues are not able to understand, or have not put enough emphasis on). What if you have different opinions and other opinions, hope to be able to communicate with. In the future,
16、I will share from different angles and ways how to make it clear, accurate and efficient in the process of drawing. - Layer Settings Last time, we explored the three basic principles of AUTOCAD software: clear, accurate, and efficient. Maybe we feel a little empty. From this time on, well start figh
17、ting. Get a task, ready to start drawing, I do not know what you do first step. There may be a lot of people who start drawing directly, but thats not true. Various settings should be included, including layers, lines, fonts, labels, and so forth. The setting is very necessary, only the setting is r
18、easonable, is a good foundation for our next work drawing, will it be possible to make the next clear, accurate and efficient. First of all, talk about layers. It can be said that the definition of the layer is the most critical setting of the whole AUTOCAD software, and I find that our companys sta
19、ff layer is clear and not many regulations. Sometimes open some colleagues DWG drawings, a look at dozens of layers, and then see, most of the elements are on the 0 floor, can not help but laugh and cry. As for the different layers, it should be on one layer. It should be on one layer and not on the
20、 other. Similar questions can be found everywhere. What are the principles for layer settings? First, on the basis of adequate, the less the better. No matter what the major, at any stage of the drawings, all the primitives on the drawings can be organized by a certain set of rules. For example, the
21、 construction of professional drawings, in terms of floor plans, can be divided into: column, wall, axis, dimensioning, general marking, doors and windows, line, furniture and so on. That is to say, the plane figure of architecture, in accordance with the column, wall, axis, dimension, Chinese chara
22、cters, such as furniture, doors and windows to see the line to define the layer, then, in the drawing time, respectively, should be in which category, put the primitives into the corresponding layer to have. As long as all the elements in the drawing can be properly classified, then the foundation o
23、f the layer setting is set up. But is it better to classify the primitives? Incorrect。 For example, on the floor plan, there are doors and windows, and there are many steps, stairs and so on. Are they divided into the gate, the window, the platform and the stair? Incorrect。 Too many layers will give
24、 us a lot of inconvenience in the process of drawing. Just like doors, windows, stairs, stairs, though not the same kind of things, but they all belong to the line of sight, then you can use the same layer to manage. Therefore, the first rule of layer setting is that the less the better, the better.
25、 Two meanings, 1, enough; 2, streamline. Each professional situation is different, we can consider their own, how is the most reasonable?. Second, 0 layers of use. Many colleagues like to paint on the 0 floor, because the 0 layer is the default layer, and the white is the default color of the 0 laye
26、r, so sometimes it looks like the display is white. It is absolutely inadvisable to do so. The 0 floor is not for drawing. What is the 0 floor for? Is used to define blocks. When a block is defined, all the primitives are set to 0 layers (except when they are special), and then the blocks are define
27、d so that when the block is inserted, which layer is inserted and the block is that layer. Third, layer color definition. The layer set have many properties, in addition to name, color, line width, line and. When we set the layer, Define the corresponding color, alignment, line width. Now many colle
28、agues define the color of the layer, it is based on their own preferences, like what color to use what color, this is not reasonable. You should pay attention to two points in the color definition of the layer. First, different layers are used in different colors. In doing so, we can draw a clear di
29、stinction between colors when painting. If the two layers are of the same color, it is difficult to tell which layer the operation primitive is on at the time of display. The second point of the layer color definition is that the color selection should be based on the width of the line printed. When
30、 printing line settings more wide, this layer should choose more bright colors; on the other hand, if the print, the line width is only 0.09mm, so the layer color should choose 8 or similar color. Why do you want to do this? In this way, the thickness of the outgoing line can be visually reflected o
31、n the screen. For example, lets look at the drawings. The column layer (ZU) and the wall layer (WA) print out are the thickest, then one uses yellow, one uses cyan, these two colors are more bright in AUTOCAD. Fill layer (H) and furniture layer (fur) are defined as 0.13MM when printed, and darker co
32、lors 8 and 83 are also used when selecting colors. The benefits of doing so, we are in use, slowly understand. In addition, white is on the 0 and DEFPOINTS layers, and we dont want other layers to use white. Fourth, alignment and line width settings. Before setting up the alignment of the layer, refer to the command LTSCALE. In general, the setting of LTSCALE values should be set to 1, so in the drawings to communicate, not only. There are three commonly used linear lines, one is the Continous continuous line, the other two is the ACAD_IS002W100 point line, and
