CAD materials

livestock more than a decade of experience to share CAD CAD matters cornered over a lot, consider if those materials were learning CAD, then, indeed in some ways be proficient to master the software, if the college or fixed, but also can Mian merely strong start drawing. However, I think this is not enough, from books to real battle, there is a far cry.
I graduated from Tongji University, currently has long been a registered architect in the company looking after a lot of children. Although these babies are able to complete the design drawings and simple, but I feel from a real master and the use of CAD, there are many distance. The company's other professional, more can be hideous to describe.
Therefore, I will prepare CAD consecutive array of sensibilities and experiences, our announcements will be published at the same time, I also published here, to satisfy everyone.

AUTOCAD serial use one of experiences

use three basic aspects of
present, the company's design documents, of special note, the drawings are drawn using AUTOCAD software . However, there are still many folk are not very familiar with CAD, or that is not handy to use, so that efficiency is not high, it can be said, in our company, drawing a drawing the same speed and in slow time-consuming and may be a feud of several times. At the same time, each human feels drawn out not by the drawings look the same, some of the drawings seem at a glance, clear and beautiful, drawing not only the expression of some illegible points can be wretched over to describe.
begin engineering design from this issue, I will be drawing more than ten annuals of experience as a serial morsel by bit, to satisfy everyone, we hope to have something to learn, learn to draw or two, to develop good drawing habits, improved drawing speed. At the same time, I also hope that this is the initiate, with the opportunity and the carrier, so everyone can use CAD to launch a communication and dispute, improve each other.
In addition, because I am a construction professional, very understanding about other professions, so case in point the future and building professionals will be especially cared, and I hope we can learn by likeness.
I do not know thatthe use of CAD drawing, what is most important? On this issue, each person has an understanding of different, but in my opinion, the most important entity is all to memorize their own use What is the purpose CAD drawing.
us to project design, no matter what profession, what stage are, in fact to some design ideas or design content, expression, reflected in the design file. The drawings, is an intuitive, accurate and eye-catching, easy exchange of expression. Therefore, we done something (either the finished design documents, or as a condition of the course submitted to other professional documents, must be a good help to express their design ideas, design content.
With this premise, We ought comprehend that a nice microprocessor drawing of the drawings should have the following two characteristics: clear, precise.
clear: we ambition to express what have to be clear, a good drawing, looks at a glimpse. a see, you can sub- so clear which is the wall, which is a window, which is left hole,Know the line is the line I realized namely the me, which is the pipeline, which is the equipment; dimensioning, text and other clear, non-overlapping ... .... In adding to publish out a quite clear drawings and, in the display must also be apparently displayed. In addition to drawing a clear wording of a clear devise minds and content, is the cornerstone of improving the drawing speed.
accuracy: 200 width of the wall can not be drew 240; left hole size can not be marked is 1000X2000, but the actual quantity of volume is 1250X2100; more common blunder is clearly a wide line 3000, the measure of it is 2999.87. cartographic accuracy not only to look good, more importantly, can directly reflect the number of surface issues, for improve the speed of drawing also has important implications, particularly when changes in the drawings. We use the CAD drawing, all the time these two points should be carved in mind. only do these two points, the drawing area can basically obtain away with that.
drawing to a project manager in charge of the room will laugh and not push.
clear, accurate and efficient CAD software is used in three basic points. in CAD software, in addition to some basic drawing commands, the other a variety of editing commands , defined in various settings, can be said to revolve around a clear, accurate and efficient arrangement of these three aspects. We are knowledge all the commands in the CAD, a variety of settings, must think about, they can in these three melodrama that role; in the use of what should be focused; under what circumstances and conditions, the most appropriate use of these commands.
the first time and we talk about these, the key is to recognize that each of my colleagues able to acknowledge, or insufficient emphasis put up). If you have any different views and opinions, I hope to share with. In the future, I am from a different point of view, aspects, to share how the mapping process , the ability to clear, accurate, and efficient use of experience

AUTOCAD serial II

last, we argued the use of AUTOCAD software, three basic principles of people began to paint directly, but this is not correct. should be a variety of settings, including layers, alignment, fonts, label and so on. for all appearances of the setting is very essential, only the setting reasonable, and it is Our next work to arrange a good foundation for the drawing, be possible to make the next the most fussy software, settings, and I found that our employees to set clear regulations layer is not much. Sometimes, some of my colleagues open the DWG drawings, a look, dozens of layers, Made in, most of the map element are in the 0 layer, can not assist but laugh and cry. As should be in different layers in a layer, and it should not on a layer in a layer, similar problems abound. Layer What are the principles set it?
First, in as little as feasible on the root of enough.
no matter what calling, what stage of the drawings, primitive drawings of all the law can be used to mobilize a decisive mandate . For example, building professional drawings to plan, we can be divided into: column, wall, axis, dimensioning, general labeling, doors and windows to see lines, furniture and so on. In other words, building a professional plan to according to col wall, the axis, dimensioning, general character, doors and windows to see lines, furniture, etc. to define the layers, and then, when the drawing, respectively, in which category should be, put the pixel into the corresponding layers must go.
As long as all the drawing primitives can be classified appropriate way, then set the foundation layer to build better. However, pixel classification is not the more detailed the better? erroneous. For example, building plans , there are doors and windows, there are many steps, stairs, etc. to see lines, it is not on the ground into the door, window layer, Taiwan, class, stairs layer it? erroneous. layer too much, give us the following in Draw the process instead of an inconvenience. like doors, windows, stairs, stairs, although not the same type of thing, but all are seeing wire, it can be managed with the same layer.
Therefore, layer settings The first principle is based on ample as possible. two meanings, 1, enough; 2,Develop their own, streamlined. The situation is different for each profession, we can on her own, how is relatively the most rational. s Second, the use of layer 0.
like many of my colleagues on the drawing layer 0, layer 0 is the default layer as the white color is the default layer 0, it sometimes seems, the screen luminous white one. This absolutely undesirable. 0 layer is not used to drawing, and that layer 0 is used to do it? is used to define the block. definition of the block, the first pixel of all layers are set to 0 (with except when special), and then define the block, so when you insert the block, which when inserted layer is the layer of the block.
Third, the definition of the color layer.
set a lot of layers property, in addition to map names, there are color, line, line width and so on. When we set the layer, we must define the appropriate color, line, line width.
immediately numerous of my colleagues in the meaning of the color layer , are based on their hobbies, favor what color to what color to do so was unreasonable.
layer of color definition in mind two points, one in general use different layers of different colors. to do so when we are drawing to be able very clear in color to distinguish. If the two layers are the same color, then appears, it is laborious to decide the map element is operating in which layer.
wafer color-defined second point namely the choice of the color typography line width should be based aboard the thickness to choose from. print, the more wide line to set the layer to be accustomed, the brighter the color; the additional hand, if print, the line length of only 0.09mm, then the color of the layer should be chosen No. 8 alternatively a similar color. why? This intuitive on screen to reflect the line thickness. For example, everybody to look photos. pillar layer (ZU) and the wall layer (WA) namely the most thick printed out, then a yellow one with the blue, both color in AUTOCAD is relatively sunny. fill layer (h) and Furniture Layer (fur) in the printing line width is defined for the 0.13mm, then, the choice of color, but likewise with a darker color, 8 and 83. This has the vantage, we in use, gradually began to feel.
In addition, the white layer and are DEFPOINTS layer 0, and we do not let the other layer of white. Fourth, the linear and the line width setting.
linear set in the layer before that LTSCALE this command. General is, LTSCALE set amounts ​​should be set to 1, so that when the interchange during the drawing, will not hell broke loose. There are three commonly used linear, one Continous consecutive line, the second is ACAD_IS002W100 dotted line and the third is ACAD_IS004W100 dotted line. like 14 when the before version of CAD used in invisible, dot, which does not recommend that you use.
disburse attention to the width of the set afresh. a drawing is pleasing, is clear, one of the ingredients major one of which is if the class of clear. a map, there is a svelte line 0.13, 0.25 for middle width lines, with 0.35 in the thick, so enriched. print the drawings, a look, also along to the thickness of lines to distinguish among the different types of primitives, where a wall, where is the windows and gates, where is the label.
Therefore, we set the line width, be sure to clear the thickness. If a map is a full-width can also seen in the quondam with so-so to describe it, doors and windows line the wall lines than can be said also of raw mistake.
There is also that we should pay attention to. Now we have two specifications design buffet, one in accordance with the proportion of printing, At this time, we can use the line width 0.13 0.25 0.4 The thickness of the specification. If we are not in accordance with the proportion of printing A3 size, this time set the line width in proportion to the size smaller than 0.09 0.15 0.3, so as to the small figure seems clear-cut.
layer settings, the main aspects of the above areas should pay attention to. In addition, in the drawing, they also point to note is that all of the primitives of the varieties of properties are to go as far as possible with the floor. Do not this line is the WA level, the color is yellow, then become a dot-dashed line. try to keep the primitive layers of the same properties and that is the plan as much as possible Element attributes are Bylayer. so help us drawing the clear, accurate and efficiency. These are the serial I and serial Second, the current will write so much (4000 words) and see all reactions, more than Replies , I will come back the contents of the posts will come up. (estimated finish it, there are 10,000 words). If we answer well, after no longer continue. hope a lot of support and encouragement.
days ago to agree in activities to Suzhou, and came back to see altitude post has been the essence of Replies are many, very merry. Replies, there are two things that I write also shallow, it is. The purpose of my writing this material is to allow a person will use CAD software, how to join their work, will be more rational use of CAD. The code words are also from this outlook. because, around me in contact with partners, there are Many of the CAD software are very skilled, but a closer look, there are many basic principle of the thing has not mastered, or do not apply to the most reasonable. So I think I was not 降龙十八掌 out this matter, but breathing is the most basic of luck. For a thorough grip of the inner strength, progressive to practice martial masterpieces, the natural matter of course.

AUTOCAD serial use the experience of three

- font, jot the settings and CAD templates File
last, we discussed the AUTOCAD software layer set several principles, then, we'll browse a few other settings I think need to know.
font settings (Style ).
in AUTOCAD software, you can use the font there are two types. One is located in the Fonts catalogue AUTOCAD, the character of the suffix shx, this category is the CAD's proprietary character, English letters and Chinese characters belong to a different font. The second category is cached in the WINNT or WINXP, etc. (see system uses the operating system) in the Fonts direcotry, the font name suffix ttf, windows of this class is system's general character,Do no forget apt update the antique system, Window, in addition to CAD, other, such as Word, Excel and other software, are also used in the font. which have included Chinese character alphabet.
we defined CAD fonts Both fonts can be used,GHD Purple Butterfly 2011, but they each have their own characteristics, we have to discriminate use. The first postfix appoint shx the font, font greatest trait of this type is that less system resources. Therefore, Under customary circumstances, I suggest the use of such fonts. Our enterprise attempts a sceic.shx, sceie.shx, sceist01.shx three fonts, which is the Chinese temperament font sceic.shx, sceie.shx in English fonts, sceist01.shx is a professional with a common structure of the English character characters. I strongly recommend, my company's drawings, except in special circumstances, always adopt sceic.shx, sceie.shx, sceist01.shx three font files, so that , drawings can be unified, format.
that the font ttf suffix when using it? There are two cases. One of your drawing document exchange with other companies, so, using Times New Roman, bold way the font, you can ensure that other companies in the open your file without whichever problems. The second position is to do the procedure, cover other situations. because this type of font files is very large, a variety of styles Yes, diversity, and looks better. Therefore, in the words need to educate polished achieve, it can use this type of character. We define fonts, and some to pay attention.
First of all, the same is enough circumstance, the fewer the better principle. this point, should be applied to CAD in all settings. No matter what type of setting, are speed up CAD files will result in greater flee the software, they might give expression speed impact. more critical is set, the more lightly in the classification of the primitive mistake.
I am using CAD, in addition to the default Standard font, in general, there are only two font definitions. One is the accustomed definition, the font width is 0.75. general all the Chinese characters, English words are using this font. The second font definition using the same font with the first, but the font width is 0.5. This is a font, When the dimensions of my special fonts used. for, in most of the construction plans, there are many small size are mobbed together. At this time, the use of a narrower font, label will dilute a lot of overlap to occur. label set (Dimstyle).
label inside the options defined a little more, but pay attention to where'd much. I would normally define a set, for those special circumstances, I will modify the individual property, and then use the Format Painter to the other brush. introduce my definition of commonly used label set it (1:100 scale drawing).
lines and arrows: the choice of all color and line width are Bylayer, indicator size 150, several other file are generally in the 100 ~ 200.
Text: Text Style To select the width of the formerly said 0.5 is defined as the fonts, colors still Bylayer, text elevation 350, the text is vertically above the level set , from the measurement line offset 60, aline text and size.
need to be modified according to a digit of other options, without attention to local.
unit set (Units).
unit set the options, I base people like to use options on the accuracy of length 0, that is a bit as a unit. this point, I recommend 3 to 4 after the decimal point. In the opening of the chapter, the I accented that accuracy is the basic point AUTOCAD using one of the three. If we define the length of the bit precision, it will bypass the many minor mistakes, such as the 1000 line, in fact, been drawn into 999.97. In are carried out each time before drawing the above definition, more distress, so AUTOCAD company provides us with a very good way is to dwt template. Every time a drawing in the current time, CAD software will let us open a dwt template file, the default is acad.dwt. and we created their own set of custom settings, you can build your own template file to save all the settings and definitions. I dwt template that I spent a few hours carefully selected some of the plans, including simple plans, elevations, sections, like the staircase, a large, common block dozens (of course, classify and organize the good). In this way, every time I have a fashionable on a project, you can open this module to work. may be some people inquired how to create dwt file, very simple, save the file, select Save As, then select the file type dwt on it. AUTOCAD
achieved the set in the last reiterate that approximately Purge this command. Purge this command to clear out the diagram is no used all the settings, block and other message, we recommend you use a lot, I am about every Purge time ahead going to retention me because a moment.
last sum up, AUTOCAD in the setting of clear and coherent is to use CAD software, phoned for the company's various divisions and bureaus of professional, are seemly to the sectjust about as to establish a set of the professional standard setting and implementation. If we can ever do have regulations for each profession, standardization, and that only within the professional in the professional The assembly of information submitted, be sure to increase the efficiency of many.

AUTOCAD reg code use the experience of four

- commonly used commands and shortcuts to set the principles
AUTOCAD software has a lot of commands, how to master some of the major commands, and the reasonable use? I often discuss with others in the CAD, to draw or edit a unattached pixel, in general there are several ways As a qualified cad-drawer, should be causativeable use of the most appropriate method.
CAD in our first look at what order? we can put them into several categories. One is drawing class, second class is Edit categories, three categories are set category, four are other categories, including annotations, views, and so on. We are a class of a class.
first level, drawing class. commonly used commands are:
Line Line
xline tectonic line (used to draw assistant lines)
mline wire (often used in painting the wall line, but also define their own use other line)
pline polyline (most of the plans at the line sections unit, to define the polyline to polyline defined, so that choice is more convenient)
rectang rectangle (actually four paragraphs encircled polyline)
arc arc
filled surround round
hatch (Note that the proportion of patterns)
boundary border (in the measurement area, fills, etc. will be used)
block definition block (to be defined in the block ambition be prepared for the unlock of all prehistoric to 0 level, all other attributes are to bylayer)
insert into the quick (likened with the-insert, a dialog box will send up a no)
the second category, edit categories. commonly used commands :
Matchprop feature mate (the equivalent word in the Format Painter, is commonly used in the operation of the brush into the correct pixel layers)
Hatchedit fill pattern redactor (double click the left mouse button to fill in the pattern)
Pedit polyline editing (also can be used to segment paragraphs, connected end to end of the polyline)
Erase erase
Copy copy
Mirror Mirror
Offset pan
Array array
Move Move
Rotate Rotate
Scale zoom
Stretch extend extend
Lengthen (not commonly used, but in the need to extend the non-horizontal or vertical line segment when it is convenient;! also be achieved the same function, we first look on her own)
Trim cut
Extend extension
Break interrupt
Fillet fillet
Explode broken (can be used for playing pieces, polylines , double, etc.)
Align combination (not commonly used, but in the slope of the graphics draw some useful, of being able to map the painting, good painting and then adjust back to the original angle. and the UCS are two conceptions )
Properties property (with the 14 version of ddmodify, amenable out of the property sheet, in which to view and adjust almost all of the properties of primitive, useful)
to the drawing commands class and further editing classes some explanation.
First, we have drawn, in general, can edit the command to complete, do not use the drawing commands to complete. in the process of using CAD software, however the drawing has been said, but in truth large some are in the edit plot. because the editing primitive drawing primitives can significantly reduce the become of inexact and can improve efficiency to some extent.
Second, using the drawing commands, be sure to set the capture (to capture set, after repeat that), F3 switch.
Third, the use of drawing and editing commands, in most cases, should the orthogonal mode, F8 to switch.
Fourth, I listed out of more than drawing and editing commands, as a cad-drawer, must be able and proficient in the use of other not listed in the drawing and editing commands, you should understand, at the fitting time to use.
third classification, Set class. in front of a lot of talk, not repeat
fourth category, other. and there's content there are a lot of us were narrated. (which there will be a command which involves Express)

access down and talk about how to customize the shortcut key.
defined shortcut keys stored in the acad.pgp file, 2004 version (and maybe 02 version, remember) to change the placement of the directory, we own Click inside the search windows to know. shortcut keys can be based on each person's preferences, the definition of liberty. However, I think that emancipation does not mean fortuitous, should have some principles.
one, no paradox, try not to use fully irrelevant letters. For example, copy the command, do not use the letter v to define shortcut keys. so easy to cause misunderstandings, forgotten. Even if he remembered, others one to your machine up to absolutely fainted.
Second, according to the frequency of each command to define shortcut keys, definition, followed by br> Take the simplest example, copy and circle. In the default setting cad, duplicate is the co / cp, circle is c. This preparation is absolutely unreasonable. In general, duplicate to use circle to high frequency ratio many so, at first should be to c is defined as the copy shortcut. and then, for the circle, can be used cc (the first and fourth letters), may also ce (inclusive of two letters), the two have been occupied or not used, then using ci.
for commonly used commands, my proposal is that we must use the shortcut key, use the shortcut key pick the icon with the mouse than, or in the list select the command to fast on a lot of time . we must develop a left hand keyboard, right mouse habits. what counts as common commands? I recommend more than 5 times per day the order appears, should be attributed to common commands.
everyone on the rule that to define effective key, after 1 to 2 days of train, we can enhance the efficiency of many.

AUTOCAD serial use the experience of 5
- Layer control command, view command, primitive selection method
layer commands are control commands and view CAD commands, these commands are the key, whether skilled, will greatly influence the efficiency of the drawing.
take a look and layer on command. and layer-related command is actually mostly in the Express (02 version seems to be in the Bonus), in the installation of AUTOCAD, be fully installed in order to seem.
Layers command, first, of course, is the layer, Layer Properties Manager. inside the characteristic content of previously discussed in more detail, this will not repeat. and layer control of the other commands, the drawing process, let us all how easy to control layers of the pixel belongs to the selected layer. This command in the toolbar there, we should have been more familiar.
laycur (change to present layer) change the pixel belongs to the selected layer to the present layer.
and switch on) open all the layers.
and , other layers are locked (plug-in primitives for the last selected layer (similar to matchprop, but choose the opposite order of primitives)
Layers command hope we can cost a little time to chance versed and main, of course, invested that the layer drawing primitives category regulations set clear. This can not, then all of the answer. The above three commands, playing one asterisk, may be overlooked is our usual, but very profitable command.
view command has three.
The first: redraw (redrawall) redraw, regen regenerate. commonly used is the redraw, in some auxiliary display point, the auxiliary display redraw lines can not be cleared, try using regen.
second type is a view zoom class. This class is effectively the manifold branches approximately the zoom command. commonly used are:
zoom-default real-time zoom
zoom-p behind on the coverage of a outlook of the dynamic scaling
zoom-d view
zoom-a show all view
zoom-w Display the selected view window
third category is the view of the scope of translation classes. is the pan and its branch command.
I do not know in view of control, is the mouse to select toolbar icons, or use the keyboard command? think about before, in order to assist the behaviour of view of control, often using transparent command. in more than 00 versions of AUTOCAD and three-button mouse (medium button for the roller) appears , zoom and pan the view, use the mouse roller the key to meet the basic requirements of the.
scroll up and down the middle mouse button is the zoom of the real-time zoom, the key is pressed is the pan. and these are transparent command, other commands that can be inserted in the course of the implementation of the order. using a three-button mouse to control the view, we must master.
As mentioned the use of the mouse to click and mouse are also talking about closely narrated to primitive selection method.
our actions during the editing commands, the inevitable choice to be primitive. to select editing commands and primitives, the commonly used two ways. I was used to is the second.
the first one mouse press or a marquee selection of primitives, this time, the chosen pixel was highlighted. and keyboard input amending commands to operate. In this way, you can use Shift opener to clear excess elected primitives.
second, first with the keyboard input editing commands, and then select the required confirmation primitive operation, select the operation is completed to be recognized primitive editing operation again. This way, I think that in choosing to be primitive in this portion of the operation is more convenient and flexible, you can help by assisting key to select.
P - previous, select the last operation primitives.
R - remove, Removal of selected primitives.
A - multiplication, increase choice primitives (for use after remove).
Both methods contain some of the same place and use the mouse.
left mouse button. the left mouse button is used to select objects.
elect the left one pixel directly.
Second, under the left mouse button, the right or bottom right side of the drag, and release . Then there is the solid line selection box, only entirely solid line box of the primitives can be selected.
Third, beneath the left mouse button, the left or lower left side of the shuffle, and release . Then there is the dotted selection box, by the time some in the dashed box in the primitives can be selected.
right.
the character of the right mouse button is also magnificent, we need to change it AUTOCAD system configuration. In the Select certainly be slower than on the right to achieve the same purpose. suggest you give it a try, wondering surprising.

AUTOCAD serial use the experience of 6

- Graphics and Print proportional control, apply the map carton, mark the command
after drawing in the drawing, we have to print out the drawings, only when the drawing to print out (drying white paper map or a chart for sulfuric sour) only after the basic work that we completed the drawing (of course, prepared for the packages, etc.). print, there is a ring can not be dodged, that is, ratio. print causativeable scale and drawing scale, then the finished drawing to a clear and beautiful beauteous. We often see some drawings, many, and some drawings vacant, the proportion of these are of inadequate control. then print the drawing percentage and proportion, we are early in the drawing, and drawing consideration to what they should do?
general, we have the last print of the drawings and in accordance with the proportion of not in accordance with the ratio of two. in accordance with the ratio, generally construction plans; not in accordance with the proportion of cases there are many, generally have the program text, the process map (that looks), the condition graph, in recent years, the preparatory design (design evolution ) has gradually become the text printed not in accordance with the proportion of A3 size.
first look at the print mart drawings to scale. construction plans are basically in proportion to the plot, but there will be different in the proportion of plans settings. For example, Ping Li profile are generally 1:100, stairs, bathrooms are 1:50, 1:20 node is a large sample, fitting a large sample of nodes in the graph may be 1:10,1:5 , the ratio of 1:2 so the total figure of the common ratio is 1:500, so sometimes there 1:1000,1:2000. I stand next to a pack of smooth profile, the staircase, bathroom large sample and nodes of the architectural and large-like drawings to illuminate.
First, we are beginning to draw the common plan, then we should really correspond to each 1MM in AUTOCAD to draw each standard unit 1, then down sections of other legislation also. At this point, we have two locations should be noted, first, basically all of the fonts height should be set to 350 or so names can be slightly larger room, drawing distinct name, and other special font height set. Secondly, after making dimension, the dimension of the described.
1:50 ratio followed the stairs like a large sample and large bathroom. In drawing such a map, I usually plan in the first copy to the original drawings of the pertinent part of the next, and then remove and editing out needless part. then have to modify some things. First, linear scale, in addition to the solid line, the other, such as dashed, dotted line so to half of the original linear scale. Second, the word size, and elevation of the size of the axis Scale the size of the same number as the original 0.5 ratio. Third, the label set, all marked in this part of the size will be more appropriate.
1:20 knot the same way as a colossal example drawn, not repetitious.
drawings has been completed, must do is set the frame. Each company has its own border, and should have a different map canvas. frame in the production, most of them will follow the 1:1 ratio: A0-1194 * 840; A1-840 * 597; A2-597 * 420; A3-420 * 297; A4- 297 * 210. which, A1 and A2 map sheet of the perpendicular frame is also often used. Also, we need to use longer time frame, should be in the direction of the long side of the frame, in accordance with long frame side 1 / 4, the modulus increase. every frame no matter how much map sheet, according to a certain percentage of the print out, sign the sizes of graph should be the same. we have different frame size of the plot according to the proportion we must Scale large, in which the map can be set.
drawings to scale on a map, there are two points to make. First, not all levels should follow the built profile of the ratio of 1:100, fjust aboutme no details of the storehouse, factory, they can be used to consider the ratio of 1:150 or 1:200. so that it can make drawings and full.
second point is, no stuff what map, keep in idea when they draw the actual per 1MM AUTOCAD each of the corresponding standard unit 1 to draw (the aggregate figure can be precluded), assorted proportions of the figure only in the font size, straightforward scale, marked in alter zones marked global proportion.
course, the above is for are placed in the same proportion of the graph box contrive a graph with the situation. for different plans to put a percent figure box, the little bit of difference. We have a plan in to place a 1:100 1 : 20 nodes in a large sample to an example.
1:100 to first determine the main proportion of this figure, 1:100 plan drawn in consensus with the above usage is completed, 1:20 node bulk sample, also drawn, as described above,
