11、选择时比较方便）用矩形（实际上就是四段围合的多义线）电弧圆弧圆圆孵化填充（要注意图案的比例）边界边界（在计算面积、填充等情况会用到）（0块定义块需将准备用于定义块的所有图元放到层，其它所有属性均改为-）插入插入快（与插入相比较，一个会调出对话框，一个不会）第二类，编辑类。常用的命令有：特性匹配特性匹配（相当于字中的格式刷，常用于将正在操作的图元刷成正确的图层）图案填充填充图案编辑（鼠标左键双击填充的图案即可）编辑多义线编辑（也可用于将几段首尾相接的线段连接成多义线）擦除擦除复制拷贝镜镜像平移偏移阵列阵列移动移动旋转旋转规模缩放拉伸拉伸延长拉长（不常用，但在需要延长非水平或垂直的线段时很方便；！

12、也可实现同样的功能，大家先自己琢磨看看）装饰裁减扩展延伸打破打断角倒圆角爆炸打碎（可用于打碎块、多义线、双线等）对齐对齐（不常用，但在画一些倾斜的图形时很有用，可以把图对正了画，画好了再调整回原来的角度。和UCS是两个概念）性能属性（同14版时的ddmodify，可调出属性表，在其中可查看和修改该图元的几乎所有属性，很有用）就绘图类和编辑类的命令再进行一些说明。第一，我们在绘制中，一般来说，能用编辑命令完成的，就不要用绘图命令完成。在CAD软件的使用过程中，虽然一直说是画图，但实际上大部分都是在编辑图因为编辑图元可以大量减少绘制图元不准确的几率，并且可以在一定程度上提高效率。第二，在使用绘图命

13、令时，一定要设置捕捉（捕捉的设置，以后再讲），F3切换。第三，在使用绘图和编辑命令时，大部分情况下，都要采用正交模式，F8切换。第四，The drawing and editing commands I have listed above, as a cad-drawer, must be well versed and skillfully used. Other drawings and editing commands that are not listed should be understood and used at the appropriate time.The third c

20、ourselves.)Align alignment (not very common, but useful when drawing some oblique shapes. You can draw the picture right, draw it, and adjust it back to the original angle. And UCS are two conceptsThe Properties property (with the ddmodify at the 14 edition, you can call up the property table, where

21、 you can view and modify almost all of the attributes of the primitive, useful)Purpose and standardThe most important thing to do with CAD drawing is to always remember what you are using CAD for drawingCAD software uses three basic points: clear, accurate and efficientDrawing Combat: received a tas

22、k, it should be a variety of settings, including layers, lines, fonts, tagging, and so on. The setting is very necessary, only the setting is reasonable, is a good foundation for our next work drawing, will it be possible to make the next clear, accurate and efficient.The drawing class and the edit

23、class command are explained in more detail:First, we dont use the drawing command to complete the drawing, in general, with the edit command. In the use of CAD software, although it has been said to be drawing, but in fact, most of them are in the edit map.Because editing primitives can greatly redu

24、ce the probability of drawing primitive inaccuracies, and can improve efficiency to some extent.Second, when using the drawing command, you must set the capture (capture settings, later), F3 switch.Third, in the use of drawing and editing commands, in most cases, the use of orthogonal mode, F8 switc

25、hing.Fourth, I set out the drawing and editing commands, as a cad-drawer, must be proficient and skilled use of the other not listed the drawing and editing commands, should understand, use at the appropriate timeF3: controls whether objects are caught automaticallyF7: raster display mode controlF8:

26、 orthogonal mode controlF9: grid capture mode control (Ctrl+B)F10: polar axis mode controlF11: object tracking control (Ctrl+W)Layer setting principle:First, on the basis of adequate, the less the better.Architectural drawings, in terms of floor plans, can be divided into: column, wall, axis, dimens

27、ioning, general marking, doors and windows, lines, furniture and so on.The first rule of layer setting is that the less the better, the better. Two meanings, 1, enough; 2, streamline.Second, 0 layers of use.The 0 layer can not be used for drawing, and the 0 layer is used to define blocks. When a blo

28、ck is defined, all the primitives are set to 0 layers (except when they are special), and then the blocks are defined so that when the block is inserted, which layer is inserted and the block is that layer.Third, layer color definition.The set has many attributes, in addition to name, color, line wi

29、dth, line and. When we set the layer, we should define the corresponding color, alignment and line width.You should pay attention to two points in the color definition of the layer. First, different layers are used in different colors.The second point of the layer color definition is that the color

30、selection should be based on the width of the line printed. When 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

31、, the thickness of the outgoing line can be visually reflected on 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 furnitu

32、re layer (fur) are defined as 0.13MM when printed, and darker colors 8 and 83 are also used when selecting colors. The benefits of doing so, we are in use, slowly understand. I (to explain, is because the printing of sulfuric acid paper, according to the grayscale display, so bright color, print out

33、 a shallow, suitable for thick lines; dark color print is deep, suitable for fine lines; such a printed map, clear black and white ash, drawing spirit, at a glance. Also, the ink. In addition, white is on the 0 and DEFPOINTS layers, and we dont want other layers to use white.Fourth, alignment and li

34、ne width settingsBefore 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 common types of alignment,One is the Continous continuous line,Two is the ACAD_IS002W

35、100 mark line,Three is the ACAD_IS004W100 dotted line.Like the previous 14 edition of CAD used in hidden, dot and so on, not recommended for you to use.The setting of line width is fastidious again. Whether a drawing is beautiful or clear, one of the important factors is whether it is well arranged.

36、 A picture, there are 0.13 lines, a medium width line 0.25, line 0.35 is rough, so rich. The printed drawings look at one glance,Also can according to the thickness of the line to distinguish different types of primitive, what is the wall, where is the door and window, where is the mark.So, when wer

37、e online wide, make sure the thickness is clear. If a map, all is a kind of line width can also be used to look at the past to describe the words, doors and windows lines thicker than the wall line, it can be said to be wrong.PrintNow we have two specifications for drawing,First, according to the pr

38、oportion of printing, at this time, our line width can be used 0.130.250.4 this thickness specification.Do not print A3 specifications in proportion, at this time the width of the line is smaller than the proportion of 0.090.150.3, so that the small picture looks clear.When setting up layers, there

39、are several main points to pay attention to. In addition, in drawing, there is also a point to note that all the attributes of the primitives are as far as possible. No, the line is WA, the color is yellow, and the line is dotted again. Try to keep the meta attribute and the layer is consistent, as

40、far as possible the graphic attributes are Bylayer. This will help us to improve the clarity, accuracy and efficiency of the drawingsFont, callout settings and CAD template filesFont setting (Style).In AUTOCAD software, there are two classes of fonts that can be exploited. One is stored in the AUTOC

41、AD directory under the Fonts, the font suffix called SHX, this category is CADs proprietary font, English letters and Chinese characters are divided into different fonts. The second category is stored in WINNT or WINXP (see the system operating system) under the directory of Fonts, font name suffix

42、TTF, this is the general character of the windows system, in addition to CAD, others, such as Word, Excel and other software, are also using the word library. Among them, the Chinese character library already contains the English alphabet.When we define fonts in CAD, two fonts can be used, but they

43、each have their own characteristics, and we should distinguish them from using them. The first kind of suffix is called SHX, and the biggest characteristic of this kind of font bank is that it occupies less system resources. So in general, I recommend using this type of font. Our company provides sc

44、eic.shx, sceie.shx, sceist01.shx three fonts, in which sceic.shx is the Chinese character library, sceie.shx is the English font, sceist01.shx is a common structure with a professional symbol of the English font. I strongly recommend that our drawings, except for special cases, use sceic.shx, sceie.

45、shx, sceist01.shx, these three font files, so that the drawings can be unified and formatted.When is the suffix TTF font used? There are two cases. First, your drawings and documents should be communicated with other companies, so you can use the fonts such as typeface and boldface to ensure that ot

46、her companies dont have any problems opening your files. The second kind of situation is when the scheme, cover and so on. Because this type of font file is very large, all kinds of styles have, a variety of, and more attractive. As a result, this type of font can be used when the word aesthetic eff

47、ect needs to be taught. When we define fonts, there are some more to note.First, the principle of less as good as possible. This should apply to all settings in CAD. No matter what type of setting, the more the CAD file, the more likely it will affect the speed of the operation. More importantly, th

48、e more settings you have, the more likely you are to make errors in the classification of primitives.When Im using CAD, except for the default Standard font, there are usually only two font definitions. One is a regular definition with a font width of 0.75. In general, all Chinese characters and Eng

49、lish characters are in this typeface. The second font definitions use the same font as the first one, but the font width is 0.5. This font is my special font for dimensioning. Because, in most construction drawings,There are a lot of small sizes crowded together. At this time, using a narrower font,

50、 tagging will reduce a lot of overlap occurs. Callout setting (Dimstyle).There are a few more options in the callout definition, but theres not much to be noticed. I usually define a setting, and for special cases, Ill modify its properties individually, and then use the format brush to brush it. In

51、troduce my commonly used annotation definition setting (1:100 scale drawing).Line and arrow: all colors and line widths are Bylayer, arrow size 150, and several other data in 100200.Text: width defined text style to choose the previously mentioned 0.5 font, the color is still Bylayer, height of 350

52、words, text position for vertical above the level of the size, from the line offset 60, and the size of text alignment.Other options are adjusted as needed, with no attention to place.Set of units (Units).In the unit settings option, I find that someone likes to use 0 for the length accuracy option,

53、 that is, the unit as a unit. For this, I suggest changing to 34 after the decimal point. In the beginning, I emphasized that accuracy is one of the three basic points of AUTOCAD usage. If we define length accuracy as a bit, we will ignore many minor errors, such as 1000 line segments, which are act

54、ually painted 999.97. These definitions are more troublesome before each drawing, so AUTOCAD provides us with a very good solution, that is, the DWT template. Each time a new drawing is created, the CAD software lets us open a DWT template file, and defaults to acad.dwt. After we have created our ow

55、n set of custom settings, we can build our own template file to save all the settings and definitions. My DWT template is I spent a few hours, some of the map carefully selected, including simple plan, elevation, section, stair like each one, common block dozens (of course, classified good). So, every time I start a new project, I can open this module and start working. Some people might ask how to create a DWT file, which is simple, when you save the file, select Save as, and then select DWT in
