56. the old users multiple replication in CAD is always required to enter M, streamlining?
You can add in acad.lsp files without having to enter the program realization: M
(defunC:CVV()
(setvar"cmdecho"0)
(setqcss(ssget)) (command"copy"css"""m")
(setqcssnil) (setvar"cmdecho"1)
(prin1))
That is, enter the CVV return, multiple replication can be implemented.

57. How do I replace a missing original fonts?
Replication of the fonts you want to replace, as will be replaced by the character set names, such as: open a picture, tips not found font jd, you want to replace it with hztxt.shx, then you can go to AutoCAD font folders (font) inside a copy of hztxt.shx, renamed, and then in turn jd.shx XX.shx into font inside, when you reopen the diagram. Later, if you open the map containing the jd you camera, there is no font, you'll never go to you to find a font substitution.
58. how to remove stubborn layer?
Method 1: turn off unwanted layers, select all, COPY paste to a new file, those useless layer won't stick around. If you do not have in this layer defined block, and another layer to insert the block, so this not layers are not able to use this method to delete.
Method 2: select the graphics need to leave behind, and then select the file menu-& gt; gt; & output-block file, this file is to select a block of some of the graphics, if the graphic is not in the specified layer, the layer will not be saved in the new tile graphics.
Method 3: open a CAD file, to delete the layer off, in leaving you need visible graphic, point to file-save as, and determine the file name, file type .DXF format column, select * from the dialogue window, point to tools-options-DXF options, and then select the object, call hook, click OK, and then points to save, you can choose to save the object, the visible or graphic you want to use the chosen can be determined after the completion of the save, and exit the file you just saved, and then open a look, you'll find that you don't want the layer to disappear.
Method 4: use laytrans command, you can delete the shadow layer to layer 0, this method removes the object with the entity or by any other block nested defined layers.

59.AutoCAD in XP operating system the following fatal error when printing?
This version uses AutoCAD2002 and above print meter. In 2000, additional print meter features a lot of BUG, this feature in the 2002 version directly as AutoCAD functionality. This feature is at 98 operating system completely without problems, but in some XP system, an error occurs. So XP systems it is best not to turn on this feature. If you have unfortunately this feature is turned on, the AutoCAD in a fatal error occurs while printing, the solution is this: the root of the AutoCAD AcPltStamp.arx file is found, change it to another name or deleted so that print will not be wrong, but also less print meter feature, the method for version 2002 and 2004 editions are valid.

60. in multiline text (mtext) command in the edit text with Word97.
Mtext multiline text editor is a new feature in AutoCADR14, it provides Windows word processing software of the interface and work methods, it can even take advantage of the powerful features of Word97 to edit text, this feature can be used as follows: open the "Tools" menu select "Preferences" command, "Preferences" dialog box pops up, open "Files/TextEditor, Dictionary, andFontFileName/TextEditorApplication/Internal", double-click on the "Internal", "dialog box appears" Selectafile, he went on to found the "Winword.exe" application file, click "open" button, then click "OK" to return. After completing the above setup, users like to use mtext command system will automatically call our familiar Word97 application, text for AutoCAD.

61.AutoCAD Map import photoshop.
This is a very old problem, the solution is the "virtual printing" to a step below. (for the convenience of everyone, in English, the parentheses is the English version):
A, open the "file (file)" menu under "printer Manager (plottermanager)".
B, running the "Add Printer Wizard (Add-A-PlotterWizard).
C, click on the "next (next)", on the right of option, select "my computer (MyComputer)", continue to the "next" and enter "printer model (PlotterModel)" select the page.
D, on the left of the "vendors (Manufacturers)" select the "raster file formats (RasterFileFormats)" this is what we can see in the right "model (Model)," lists the many familiar graphics format, I used to use JPG cellType, select the "Independent JPEG Group (IndependentJPEGGroupJFIF)", click on the "next (next)", until complete. So we can add CAD graphics output bit JPG format. Next we look at how to use it.
E, CAD and do a plan, we open the "file (file)" menu under "print (plotter ...)". In the print dialog box, select the type of printer we just installed "IndependentJPEGGroupJFIF", in the following "print to file (plottofile)" was added to the generated file name and path, the file is one you can then edit graphics in photoshop. In page setup, select a dimension that we need to rest and to use the real printer method is the same. Click Print, and so after a few seconds, the graphic is generated.
Note: the default page size is only 1280 * 1600, this size will not be able to satisfy our needs. We can in the printer's properties to customize the size we want.
Enjoy! added: If the CAD is 2004 or later, you do not have their own loading printer, the print device has a "PublishToWebJPG.pc3" printer, directly on the line
F: Supplement to the point were the teacher if you want to export a solid black line recall to plot of all colors of the pen, are changed to 7 colors, so that you can export pure black figure, remember to put in PS to RGB mode, so that the image is clearer.

62. After you finish modifying the ACAD.PGP file, you do not have to restart immediately loaded AUTOCAD just modified ACAD.PGP file.
Type a REINIT command, hooks, and then determine the PGP

63. resolve AutoCAD2005 method cannot be registered.
Remove the hidden files and folders. Delete C:\DocumentsandSettings\AllUsers\ApplicationData\Autodesk\SoftwareLicenses\B2260000.dat

64. how to adjust the AUTOCAD drawing area to the left shows the coordinates of the box?
Press F6 to switch. Or will modify the COORDS system variable to 1 or 2. System variable to 0, use the pointing device update coordinates display the specified point. System variable to 1, is continually updated to display the coordinates. System variable to 2, continuously updated coordinate display, distances and angles when needed, to the point of distance and angle.

65. How do I switch the use in English menu?
At the same time saved in AutoCAD and English set menu system, it is possible to switch back and forth. Specific approach is to integrate the finished menu file was renamed Pacad.mnu, placed in AutoCAD installation directory in a subdirectory of \\SUPPORT, of course, also don't forget to copy into Pacad.mnl acad.mnl, drop? *** acad.mnu in the same directory. In the Chinese menu, use the menu command to load Pacad; in exchange for English menu when you load the menu command again to use acad menu file.

66. how to draw a curve?
----At the plotted drawing, often experiencing art intersection line, intersecting lines and curves. Hand-drawn very troublesome, special points and a number of General points, and even the errors of the curve. Draw with AutoCAD2000 Planar curve or space curve is very easy.
-Method 1: use the command draw 2D graphics Pline adopted special points of a polyline in the Pedit command or Spline curve Fit, can become a smooth surface curve. By 3Dpoly command draw 3D graphics through special points of a polyline, the Pedit command Spline curve fit, can become a smooth space curve.
----Method 2: use basic commands to create a three-dimensional Solids entities (rectangular, cylindrical, tapered, spherical, etc.), then by a combination of Boolean (Boolean): AC, and operations, and complex interference from obtaining, and then use the drop-down menu the entity View (view) (3D perspective)/3DViewpoint, select different viewpoints to create standard views, get a different view of the projection of the curve.

67. in the AutoCAD drawing in what proportion?
It is best to use the 1: 1 ratio, the ratio can freely adjust the output. Drawing scale and output ratio is two concepts, the output is "output 1 unit = drawing 500 units" is to press the 1/500 proportional output, if the "output 10 units = drawing 1 unit" is magnified 10 times the output. With 1: 1 scale drawing many advantages. First, easy to find mistakes, because according to the actual size of the drawing, it is easy to discover the size settings are not reasonable. Second, the dimension is very convenient, size number is, the software itself, should draw the wrong measurement, a look at the size digital discovered (of course, the software will also be able to set the dimension ratios, but always more work). Thirdly, in various local graphics between replication or use the block, the result is 1: 1 ratio adjustment block size and convenience. Fourth, by parts diagram spell Assembly or by the Assembly to remove picture parts diagram is very convenient. Fifth, there's no need for cumbersome downscaling and enlarge, improve work efficiency, prevent conversion process error may occur.
