Working Student Diary, part 1

19. AUTOCAD how to adjust the coordinates in the drawing area bottom left side of the box?

84. how to modify the dimensions of relevance?

with VIEWRES command, set it too large a number, can change the image quality.

35. in the marked text, marked up and down the subject of methods:

Tools - Options - Choose - Pick frame size and adjust it.

will CMDDIA system variable to 1. System variable to 0, the command line; system variable to 1, the dialog box.

with the list command (list)!

78. surface field, block, what is the entity concept?

with BLIPMODE command, the prompt, enter OFF to eliminate it.

copy to replace the font for the font name to be replaced, such as: open a picture, suggesting not find the font jd, you want to use hztxt.shx replace it, then you can go to AutoCAD fonts folder (font) inside hztxt.shx to copy, rename jd.shx, and then into the font in the XX.shx inside, re-open the map on it. After you open the map contains jd machine yard so you do not have the font, it will never stop looking for the font you want to replace.

Yun good 1:1 picture using the output ratio can be easily adjusted. Drawing ratio and output ratio of the two concepts, the use of the output 1:1 draw with many advantages. First, the easy to find an error, because the actual size drawing, it is easy to find size setting unreasonable. Second, the mark size is very convenient, is the number of dimensions, measurement software itself, if the wrong picture, a look at size figures found (of course, software can set the dimension ratio, but the total is much waste of effort). Third, in each chart or graph to use to copy a block of local time, as is the ratio of 1:1, adjusting the block size convenience. Fourth, the assembly drawing or parts diagram spell removed from the assembly drawing painting parts diagram is very convenient. Fifth, do not need the cumbersome calculation of the ratio of zoom in and out, improve efficiency, prevent conversion errors that may occur during.

59. How to merge a number of lines?

Suppose there is a known length on the screen line (referring to single-line, polyline, the unknown length of course you can), and the horizontal direction with a certain angle, requires it to reduce some of the same length and direction of operation as follows: directly select the line to pinch there, move the cursor to the end and activate to reduce the pinch point, so this line can stretch the rubber band into the line, the cursor moves according to the direction of the line, the rubber band and the original line segments overlap, the distance does not limit movement, some people feel that the direction of movement is not the same as the original point of capture then auxiliary command, enter (ie near to) It put it Yo! ! !

77. why the stack button is not available?

lines and dimension lines only map, but not the value of the ready-size drawings. It is produced before the lazy approach, using computer graphics should now do not recommend this.

stack use: First, have a stack symbol (#,^,/); two is to check the contents of the stack before they can operate.

to cad2004 example cad toolbar does not show all available commands, the user is required to add their own. For example, the default drawing toolbar is not multi-line commands (mline), will add their own. Practices are as follows: View -> Toolbars -> Commands tab, select the right window shows the corresponding drawing commands then find the existing toolbar,
it appear as a separate toolbar; otherwise have become a toolbar. Then they found just out of the ! Necessary for him to add the icon. Practices are as follows: out of the command, do not close the Customize window, click the At this time, we can find, cad allows us to custom icon to each command. Such as a personalized toolbar becomes easy up! ! Yun, the command you want to delete, repeat the above operation, the towed back to the delete command, then select the confirmation required
24. how to modify the CAD shortcuts?
CAD2002 and below, directly modify the SUPPORT directory ACAD.PGP files.
CAD2004 in Tools - Customize - Edit custom file - the program parameters (ACAD.PGP) at
25. sometimes in AutoCAD intersection marked on the mouse click generated at how to do?

also features in the CAD2004 change: the positive and the direction.

20. drawing no dotted line shows how to do?

Method 1: the unwanted layers off, select all, COPY paste to a new file, not those useless layer affixed over. If this had not been defined in the layer block, and insert another layer in this block, then the layer is not in this way can not be deleted.
Method 2: Select the left graph, and then select the File menu -> Output -> a block file, the file is selected so that the block part of the graphics, the graphics do not specify if these layers, these layers will not be saved in the new block graph.
Method 3: Open a CAD file to be deleted first layer off, leaving only the surface you need to see graphics, Point File - Save As, to determine the file name, file type column in the selected *. DXF format, the midpoint of the pop-up dialog window Tools - Options-DXF option, then select the object at the tick, the point to determine, and then save, you can choose to save the object, or use of graphics to be seen on the election can determine the save, and finished just out of the saved file, then open it, you will find that you do not want the layer disappeared.
Method 4: Use the command laytrans, layers can be removed layer can be mapped to 0, this method can be removed with a physical object or defined in other blocks nested layers.

40. graphics printing techniques.

install the printer or to the absence of high-end printer with someone else enter the AutoCAD drawing, you need to print AutoCAD drawings to another computer, but other computers may not An AutoCAD, or because for various reasons (eg: AutoCAD graphics In another unusual display fonts on computer, network printing, network printing is not normal, etc.), can not use another computer to print properly, then, will be the first in their own computer to print AutoCAD drawing file to form a printer file, Then, on the other computer using the DOS copy command to the printer file output to the printer, the method is: copy prn / b, should be noted that, in order to use this feature, you must first added to the system do not specific model on a computer printer, and set it the default printer, in addition, COPY Do not forget to post Yun added / b, shows that the binary output of the printer file to the printer.

47. some commonly used keyboard shortcuts.

map can be made of one block, and the colors move to a bright color such as yellow, and then overlap the two plans together and if inconsistencies can easily be seen.

in ACAD.LSP add a: (vl-cmdf

7. insert the AutoCAD drawing in the WORD when the width problem.
When thin, use less than the width equal to 0.25; When thick, set the line width greater than 0.25 (greater than 0.25 inside the line when printing in Word, print out the width is greater than 0.5mm). Note: You must activate the line width in the CAD which shows, from inside the double-edited Word pictures, please re-check the active width. When the line width of 0.25 - 0.5 between, use a multi-line set width.
8.AutoCAD XP operating system in a fatal error when printing how to do?
this with the use of AutoCAD 2002 and above the printed stamp. In 2000, the stamp features the addition of the print, a lot of the BUG, ​​after this function directly as in the 2002 version of AutoCAD functions. This feature 98 operating system is no problem, but in some XP system error occurs. So in XP it really going to turn this feature Yun. If you have this feature turned on, unfortunately leaving the AutoCAD fatal error in the printing, the solution can only be this: the root directory in the AutoCAD file to find AcPltStamp.arx, turning it into another name or delete, so then will no longer print an error, but also less stamp printing function, the method for the 2002 edition and 2004 edition are valid.
9. AutoCAD2002 move in what is written on the wrong reason?
careful not to move the text across the lines, text size, or cad fatal error occurs, cancel the quadrature around these objects.
10. open dwg file, the system pop-up
this case you can exit and open operation, then open the restore files, confirm the system started to restore file operations.

AutoCAD to provide point coordinates (ID), distance (Distance), size (area) of the query graphical analysis to bring great convenience, but in practical work, and sometimes have to check physical characteristics of quality attributes, AutoCAD provides physical quality attribute query (Mass Properties), you can easily query entities moment of inertia, Moment of such entity's center of mass, should be noted that, for the curve, constructed a closed polyline areas should be closed with the region command localized surface area, and then execute the query quality attributes, the entity can query the moment of inertia, Moment of center of mass and other physical properties

48. simulated space and drawings space.
AutoCAD there are two different spaces: the model space and paper space (by using the LAYOUT tab).
model space viewport features: 1, in the model space, you can draw full-scale two-dimensional graphics and three-dimensional model, and with dimensions. 2, the model space, each viewport contains a view of the object. For example: set different port will be as top view, front view, side view and three-dimensional maps. 3, with VPORTS command to create the viewport and viewport settings, and can be saved for later use. 4, is tiled viewports, they can not overlap, always adjacent to each other. 5, at a time only one viewport is active, the cursor can only cross in one viewport, and only edit the active viewport (panning, zooming, etc.). 6, can only print the active viewport; if the UCS icon is set to ON, the icon will appear in each viewport. 7, the system determines the viewport variables MAXACTVP range is 2 to 64. Paper space viewport features: 1, PAPER on the status bar instead of MODEL. 2, VPORTS, PS, MS, and VPLAYER command is active. (Only MS command is activated only after using PLAN, VPOINT and DVIEW command). 3, the boundaries of the viewport is the entity. You can delete, move, zoom, stretch the viewport. 4, depending on the shape of the mouth there is no limit. For example: you can create a circular viewport, polygon viewport and so on. 5, depending on the port is not tiled, you can use a variety of ways they overlap, separation. 6, each viewport layers to create it on the viewport border and layer the same color, but the boundary line is always solid. If do not want to print out maps in the viewport, which can be placed in a separate layer, you can freeze. 7, can also print multiple viewports. 8, cross the cursor can continue to extend through the entire graphics screen, nothing to do with each viewport. 9, can be turned on or off by MVIEW command viewport; SOLVIEW command to create a viewport or use VPORTS command to restore saved in model space viewports. By default, the viewport created are active. Close some of the viewport can improve redraw speed. 10, need to hide in the print graphics and hidden-line three-dimensional graphics, you can use the MVIEW command> HIDEPLOT pick up the border to hide the viewport, you can. 11, the system determines the active variables MAXACTVP under the viewport number is 64. Through the above explanation, I believe we both have a clear understanding of space, but remember: When we first entered the drawing room, the invisible, as the mouth, must VPORTS or MVIEW command to create a new viewport or restore existing viewport configuration (usually stored in the model space). MS and PS commands can be used in the model space and LAYOUT (paper space) in the switch back and forth.

surface field is closed to create two-dimensional shape or ring zone; block is combined to form a single object (or a block defined) collection of objects (a graph in another graph in general can be used as a block); entity has two concepts, one is the visible form the basic elements of graphics, and the second refers to the three-dimensional objects for three-dimensional entity, you can use group (group)

46. Ellipse ellipse is generated polyline or entity?

---- pattern in the drawing, we often encounter draw intersecting lines, intersecting lines and curves of the other issues. Hand-drawn a lot of trouble to find special points and a number of general points, and even a big error of the curve. With AutoCAD 2000 drawing plane curve or space curves is very easy. ---- One: draw 2D graphics with the Pline command through a special point on the line, the command in the Fit or Spline Pedit curve fitting, can be turned into a smooth plane curve. Draw 3D graphics with 3Dpoly command through a special point on the line, the Pedit command Spline curve fitting can be turned into a smooth space curve. ---- Method 2: Solids basic command to create three-dimensional entity (cuboid, cylinder, cone, ball, etc.), then by Boolean (Boolean) combination of operations: intersection, and poor access to a variety of complex and interfere with other entities, and then use drop-down menu View (view) / 3D Viewpoint (three-dimensional point of view), choose a different point of view to produce the standard view, get a different view of the curve projection.

Note: The system default page size is only 1280 * 1600, this size does not meet our needs and we can customize the printer's properties we need size.
Enjoy! added: If the cad is 2004 or later, you do not own a printer installed in the printing device has a 6: add the teacher's point was, if you want to remember to export pure black linear diagram at the same time all the colors of the pen numbers are changed to 7 colors, so that you can export a plain black figure, and remember to PS in the the mode to RGB, so the image will be clearer.
13. modifying ACAD.PGP file, AUTOCAD immediately without having to restart to load the file just modified ACAD.PGP way.

modify system variables DRAGMODE, recommended changes to AUTO. System variable is ON, and then drag the object to be selected only when the command line, enter the DRAG show until you drag the outline of the object; system variable to OFF does not appear when you drag the outline of the object ; system variable bit AUTO, as you drag the outline of the object is always displayed.

DXF-Drawing Exchange File (Graphics Interchange file), which is an ASCII text file that contains the corresponding DWG file all the information, not the ASCII code format, readability, but the speed with which the formation of graphics fast. different types of computers (such as PC and compatibles and SUN workstations, using the specific different CPU bus) even with the same version of the file, the DWG file is not interchangeable. In order to overcome this shortcoming, AutoCAD DXF type provides file,Coach Audrey Collection, its internal ASCII code, so that different types of computers can be achieved through the exchange of DXF files to exchange graphic purposes, the DXF file readable, the user can easily modify it, programming, up from an external graphics editor , to modify the purpose.

when pline line width is not set to 0, the printing press when printing the line width. If the polyline width is too small, you will not get the width of the effect. (Such as drawing in millimeters, set the polyline width of 10, when you print using the ratio of 1:100, is 0.1 mm.) So multi-line print width set to consider the proportion of the job. The width is 0, can be set according to object properties (and other objects).

There are two ways to solve, first remove the acad.lsp and acadapp.lsp file, should be the same size is 3K, and then copy the acadr14.lsp twice named the two file names, with read-only, the immunity of . DWG drawing you want to delete the directory where all the lsp file. Or you can infect others. The second is a special kind of killing the virus software.
29. how to switch between Chinese and English menu?

51. how in AutoCAD using custom fill patterns for?
AutoCAD hatch patterns are stored in a library file called acad.pat, the default path for the installation directory Acad2000 Support directory. We can use a text editor to edit the file directly, add a custom design statement; also can create a *. Pat file, saved in the same directory, CAD can be identified.
Here, we create a new diamond tread plate pattern library files, for example, to illustrate the AutoCAD 2000 in a custom design approach.
First, according to national standard in CAD to diamond patterns, and mark each part size
see the following library standard format:
* pattern-name [, description]
angle, x -origin, y-origin, delta-x, delta-y [, dash-1, dash-2, ...]
title of the first acts of the line. Asterisk pattern followed by the name of execution HATCH command selection pattern, it will display the name. Square brackets by the HATCH command pattern If you omit the description, the pattern can not have a comma after the name. description of behavior patterns
second line. Can have one or more lines. Its meaning are: linear perspective drawing, fill in a family of straight lines through the points of X, Y axis, between the two filling lines displacement, the vertical distance between two filling lines, dash-n is a straight line length parameter, it is desirable is negative or zero, whichever is positive indicates that the length of the segment as a solid line, a negative value indicates that the segment is empty, take the zero point is drawn.
Well, we can start editing. Open Notepad, writing under the following:
* custom, steel plate GB/T3277-1991
68.4667, 0, 0, -9.8646, 25, 30.0213, -6.59
111.5333, 0 , 0, 9.8646, 25, 30.0213, -6.59
68.4667, -11.0191, 27.926, -9.8646, 25, 30.0213, -6.59
111.5333, 11.0191, 27.926, 9.8646, 25, 30.0213, - 6.59
pattern in this case the four lines corresponding to the line graph depicts one of the segments a, b, c, d. Graphic control, the value should not be difficult to understand. Focus here only spoke of what delta-x delta-y values ​​with the rules, to facilitate understanding, we set the UCS coordinate system as shown, to determine the origin and the X-axis positive direction. Segment a, e vertical spacing in the Y axis 25 constitutes a delta-y, is equivalent to the AutoCAD command value offset 25; if the line segment e is offset from the line through a, then e is also relative to the line segment a negative direction along the X axis moved 9.8646, this displacement is delta-x.
Here are a few precautions:
pattern definition file for each line can contain more than Yun 80 characters.
AutoCAD ignores blank lines and a semicolon to the right of the text. According to this, we can add copyright information in the file, notes, or any content that we want to join. For example:
; Copyright (c) 2000 by everyone. All rights reserved.
Yun, will save the file, named custom.Pat. Note that the file name must be the same as the pattern name.
this, I believe my friends already have a custom design approach. Now, just a little patience, you can edit a very complex pattern of.
call library methods as: filling with me to do and documents, the liberation of the Acad2000 Support directory. Open AutoCAD, run the Hatch command, in the Boundary Hatch dialog box pops up the Type column select Custom, click the Swatch Options bar, pop-Hatch Pattern Palette dialog box, select the Custom tab, specify the file we just created custom.Pat, this filling effect occurs when the right side of the preview, that's what we need diamond tread plate pattern.
52. how to use the trim command to trim the same time a number of segments?

first get the documents show that its extension (open My Computer in the Tools - Folder Options - View - to hide known file extensions in front of the hook removed); Second, we must show all file (open My Computer in the Tools - Folder Options - View - Hidden files and folders - select Show hidden files and folders); once again find the backup file (its location in the Tools - Options - File - found in the temporary location of graphic files), rename it to
15. AutoCAD2005 can not solve the registration method.

45. [TAB] key to capture the features in AutoCAD's clever use.

28. block file can not explode and can not use some common commands problem.

To change the width AutoCAD objects There are many ways. Yun normal way is to use solid color graphics on the screen to get a map of different width. In other words, when the drawing of different types of graphics according to their need to draw a different color. Then print out a different set of line width in different colors. As follows: Click In Pop-up Here we give brief pen size is how wide the decision. The size of pen width by the resolution of print devices and print the width between the decision point, the formula is / . AutoCAD will use these standard values ​​to replace the value of our free to enter. Here are some common printer Yun small pen width:
HP Laserjet III printer series with 1 / 300 Canon BubbleJet inkjet printers with 1 / 360 HP LaserJet IV printer series with 1 / 600 The new Canon BubbleJet inkjet printer with 1 / 720
understand the above reasoning, we can One such color with the The system will automatically calculate the value of similar small
44. On the issue width.

to remember as many as two or three hundred variables have a certain degree of difficulty, you can use the following method to identify which variables go wrong. To facilitate the description, there will be a file named file problem 1, create a file named file 2 (Yun good new, because that all variables are the default values, you can file with no problem), run at two files SETVAR, and then choose? List variable, the variable copying Excel, more variables which is not the same, so that queries can greatly reduce the time variable. For example: Suppose a graph in which variable ANGBASE set to 90, that if the program generates a text with the words, all words in the text will rotate 90. Variables are listed with the setvar command, then copy all the variables - paste it into an Excel file column B. Create a new file, and then setvar command will list the variables, all variables copy - paste to Excel file A column C1 in the Excel file format file type all rows, then the C column in descending order, so that value is not the same variables on the concentration of the first few columns, and then analyze these variables, and soon will be able to find out is to set the variable in question ANGBASE

with PEDIT command, the command options in a merger.

Method One: DIMSCALE determines the ratio of its dimension is an integer, the default is 1, in a certain scaling graphics should be good to change it to Yun scaling.
Method Two: format - mark style (the style you want to modify the label) - modify - the main unit - the scale factor, can be modified.
64. how to control the physical display?
AutoCAD2000 example to three commonly used keyboard input system variables control the display of entities.
ISOLINES: default entity displayed in wireframe, solid surface to points on the grid for each form of expression. The number of sub-grid controlled by the system variable, the effective value of 0-2047, the initial value of 4. Sub-grid values ​​larger entities more easily observed, but waiting longer display time.
DISPSILH: This variable controls the display side of the entity profile, the value 0 or 1, default is 0, while not shown in outline, is set to 1, shown in outline edge.
FACETRES: The variable adjustment by HIDE (blanking), SHADE (color), RENDER (rendering) the smoothness of the entity after the effective value of 0.01-10.0, the default value of 0.5. The greater its value
show more smooth, but the implementation of HIDE, SHADE, RENDER command displays the time to wait longer. Yun during the final output is usually only when they increase their value.
65. mouse button usage.

(1) Tools - Options, select on the hook removed.

5. in a Word document into AutoCAD drawing made law.
AutoCAD drawings can be first copied to the clipboard, then paste in a Word document. It should be noted that, due to AutoCAD default background color is black, while the Word background color is white, you should first change the white background color AutoCAD drawing (Tools - Options - Display - Color). In addition, AutoCAD drawing into a Word document, it is often empty side is too large, the result is not satisfactory, you can use Word picture cropping function on the toolbar to be trimmed, too much air while the problem can be solved.
6. to the AutoCAD drawing into WORD sometimes find how to do a round into a regular polygon?

83. how to make the graphics can only see but can not be changed?

Press F6 to switch. Or modify the system variables COORDS 1 or 2. System variable to 0, with the pointing device is updated when the specified point coordinates display. System variable to 1, the coordinate display is constantly updated. System variable to 2, the coordinate display is constantly updated, when you need distance and angle, the display to a point on the distance and angle.

when you need to capture a point on the object, as long as a mouse or a near object, constantly press TAb key, this or some special points of these objects (such as a straight line endpoint, midpoint, perpendicular points, intersection with the object, a quarter circle dot, center, cut points, the vertical point, intersection) displayed on the back rotation, left-click to select the desired point that can capture these points. Note that when the mouse is near the intersection of two objects near the point of these two objects have a special display rotation (dashed line changes to their respective objects), which is more complex in the graphics local point of capture is useful.

1. For simple graphics, such as rectangle, triangle. Only execute the command AREA (can be entered or click the corresponding command line command icons), at the command prompt , AutoCAD will automatically calculate the area (Area), perimeter (Perimeter), and the results are listed in the command line.

Method One: The unit of measurement is a linear scale factor alignment mark or label.
Method 2: dist command.
Method three: Use the list command. Recommended.
