<br> <br> 41. the mass properties search <br> AutoCAD provides point coordinates (ID), distance (Distance), area (area) of the query, to graphic analysis of great convenience, but in practical work, sometimes required .to query the entity quality property characteristics, AutoCAD provides solid quality property query (MassProperties), you can easily query the entity's moment of inertia, area, mass, and other entities, it should be noted that, for the curve, constructed from polylines, .you should use the closed region region command will close the regional surface domain, and then do one of the mass properties of the query to query entities of inertia, area moment, entities, attributes such as the center of mass. <br> <br .> 42. font style, font list, there are two Chinese fonts, one is preceded by a line such as "font, Arial TT?", "TT Arial". If you have previously selected font, the font will be the other way .around, if you select a font that is not?, the font is normal. You may wish to try, do not know is not what you said. <br> <br> 43. the cross cursor size changes <br> Engineering drawing ., by projection of a drawing. In order to facilitate long on Gao Qi, width, equal, drawing, adjustable cross cursor size, that is, use the options command or select drop-down menu Tools (Tools) / Options (System Configuration) ., open the Options dialog box, locate the Display (display) tab, modify CrosshairSize (cross cursor size) in the cursor and the percentage of the size of the screen or drag the slider, you can change the default value of 5%, should .not be too large, otherwise when you're drawing is very fast, because the cross hair is too big eyes very hard, impact speed. <br> <br> 44. sometimes we need not explode blocks directly modify the inserted block of text .content, you can use the refedit, specific actions are as follows: <br> A, in the command line enter the refedit "command after the carriage return, select the block needs to be modified, will pop up the reference edit dialog; < .br> B, click "OK" button, use the default settings, then the reference edit toolbar will start; <br> C, you can use the "ddedit" command to directly modify the inserted block of text content; <br> D ., content modification, click on the "reference-editing toolbar to save changes to the reference button, has been modified; <br> E, this command may also on other parts of the block, for example block in all graphic entities, etc. .; <br> F, this command on the external reference "Xref" applies. <br> <br> 45. to zoom and Pan <br> In design with AutoCAD, zoom and pan commands to use most often. Zoom, you may .lose direction, forget the original location, or forget where you want to go to, or need to quickly return to the original view. If the number of times the zoom or pan, return to the original view time knocking "fallback" (UNDO) .is tiring. <br> Fortunately, the 2006 Edition provides improved zooming and panning functionality. There is a new system variable: VTENABLE, it enables a smooth conversion to switch the display area. For example, if you perform a wide scale, and start .a smooth transition, the users can see the graphic from the partial view dynamically to the entire graphic. Smoothing the view transformation help users stay visible position in the graph. Further improved, the entire zooming and panning process, you can set them as a single .operation. <br> The settings in the Options dialog box of a user's system settings tab settings. In this way, you only need one step you can return to the previous view, really save time and effort. <br> <br> 46 .£ ® print <br> Q: PLOT and ASE command only prompts on the command line, without pop-up dialog boxes, and why? <br> A: the AutoCAD system variable CMDDIA used to control PLOT commands and dialog boxes that display the .ASE command, setting CMDDIA = 1, you can solve the problem. <br> Q: the printed chart effect is very poor, there are differences of gray line, why? <br> Answer: this is the case, most of the configuration .of the printer or plotter, driver, and the operating system. Usually the following points into consideration, can solve the problem. <br> A £ ® configure printer or plotter, error jitter switch is closed; <br> B £ ® printer or .plotter drivers are correct, if you need to upgrade; <br> C £ ® If AutoCAD configured to system printer output, swap with AutoCAD for all types of printers and plotters provided ADI driver reconfigure AutoCAD printer; <br> D £ ® on different .models of printers or plotters, AutoCAD provides command, you can further configure. For example, to support the HPGL / 2 plotter series of language, you can use the command "hpconfig"; <br> E: AutoCADPlot dialog box, set the brush ., and color and line style and the pen width of correspondence; a different color assigned the same pen number (preferably the same one), but the sum of the line, and the pen width, can be different. Some inkjet printers can only support .1-16 of pen number, if the sum of numbers is too large you will not be able to print; <br> F £ ® pen width settings are too high, for example, greater than 1; <br> The operating system if .it is g-WindowsNT, may need to update the NT patch package (ServicePack). <br> Q: after installing R14, MSWORD, what fonts have not, what happened? <br> A: the reason affecting MSWORD font is installed for .system R14 called PhantomAutoCADOLE / ADI 's virtual printer. PhantomAutoCADOLE / ADI virtual printer allows R14 to the adoption of new ADI drivers, print or draw raster graphics. R14 typical installation, and does not include this option, only in the full install or custom install, .you will have the virtual printer, sometimes it will be set to the default system printer, without making any hints. According to the MicrosoftOffice software "WYSIWYG" principle, MSWORD document the use of fonts, and the system default printer. That is, the .screen font and the printer font is the same as or similar. Windows will print printer fonts, look for a suitable screen display font, if you do not find a matching font, or the printer driver does not provide a screen font information, Windows will .select the nearest printer fonts, screen fonts. If you put the ADI PhantomAutoCADOLE / virtual printer as the default system printer fonts, MSWORD only two: morden and plotter. In the Windows system, specify the correct system printer as the default printer, MSWORD font .can be restored to normal. If the system does not have any other printer, it should be in the "printer setting", you configure a Windows system printer, even if it is a "logical" printer is also available. One thing to keep .in mind that you cannot modify PhantomAutoCADOLE / ADI virtual printer properties, but cannot delete it, otherwise it will affect the raster graphics and the output of the OLE object, may even cause a system crash. <br> Q: can achieve mass printing? .<br> A: the method a: the first graphic output to the PLT file, and then use the DOS batch file specifies the directories under PLT files batch printing. <br> Method two: R14 have specialized external functions, will be able to .take multiple graphics files, based on different print configuration file, the output to one or more printers or plotters, to achieve the purpose of the batch plot. These two modes are more flexible, less chance of error, the efficiency is higher. In the .AutoCAD program group, select BatchPlotUtility. <br> Q: is pasted into a Word document in the AutoCAD graphic print out of the line is too thin to do? <br> A: the AutoCAD graphic clip to MSWord document, it seems everything is .relatively smoothly. But when you print the document, the AutoCAD graphic lines become very small, the effect is really not good. We give users the following workaround: <br> A £ ® in AutoCAD using PostScript print driver, configure a PostScript printer. .<br> B If the background color of AutoCAD and MSWord different background colors, such as the R14 default background color is black, you have to change the background color of AutoCAD, and background color the same as MSWord. <br> C £ ® .running PLOT command, select a drawing to a file. In the brush specifies the dialog box, set the width of the pen. <br> D £ ® starts a new figure, PSIN command input the. eps file. <br> E- .then the graphics in the clip to MSWord <br> There is also a method, you can convert lines in AutoCAD to PLINE line, set the width and then copy and paste into Word. <br> Q: why do some graphics cannot be displayed ., but they do not print? <br> A: If the graph drawing in AutoCAD automatically generated layer (DEFPOINTS, ASHADE, etc.), this is expected behavior. You should avoid these layer drawing entities. <br> <br> 47 .. restoring from a backup file in the graphic: <br> First tool - folder options-displays the file name extension, and then locate the backup file, rename it to ". dwg format", at last use open other CAD file to .open it. <br> <br> 48. in the quick selection, it is possible to use FI command to set the type styles to quickly select and command FI to filter the object you want. <br> <br> 49. If .a graph, layer 1 is the contents of the layer 2 to hide, you can hide the TOOL - DISPLAYORDER - BRINGTOFRONT content displayed. <br> <br> 50. when drawing a dashed box displayed when not, for example, draw .a rectangle, point, drag the mouse without gridlines by changing the rectangle, then there is a need to amend the DRAGMODE system variable, recommend modifications to auto. <br> System variable is ON, and then select the objects to be dragged, the .only command line input DRAG before you drag the object's outline is displayed. System variables to off, you drag the object's outline is not displayed. System variable bit AUTO, always appear as you drag the outline of an object. <br> <br> .51.AutoCAD cropping techniques <br> If you want some circle (can be one of the other border) of a straight line for cropping, normal way is to select the crop boundary and then select the segment you want to crop, in fact there .are relatively simple and AutoCAD, its approach is as follows: <br> 1. in accordance with the general implementation of crop command, select the crop boundary (carriage return confirmation); <br> 2. at the prompt Select the segment you want .to crop the element type "f" (that is, the fence), carriage return confirmation; <br> 3. at the prompt: FirstFencepoint draw line segments you want to crop the intersecting straight lines, carriage return consecutive bungee confirmed. <br .> We still need attention to two points: 1. bungee straight without closed; 2. bungee lines and line segments intersect you want to crop, repeatedly cut off after the first part (this is important!). <br> <br> 52 .. [TAB] key in the capturing of AutoCAD cleverly <br> When the desiredTo capture an object on the point, as long as the mouse near a or an object, press the tab key, or the object of some special points (such as .the endpoint of the line, the intermediate point, vertical dots, and objects intersection, circle of dots, center point, tangent, perpendicular to the point, point) return rotation displayed, select the desired point left click that can be caught in these points .. <br> Note When the mouse is near the intersection of two objects in the vicinity of the two objects of the special points will successively rotation displayed (the object becomes a dashed line), this is the complexity of the graphic part is useful when .capturing. <br> In addition, for the circle Center version R14, R2000 R14 and versions of the original tangent, perpendicular to the line on the extension lines of the vertical dots, only use the automatic capture (ObjectSnap) difficult to achieve, if .using the above "you press the tab key secondary capture" method, the point of capture will become more easily. <br> <br> Import 53.cad as Excel tables <br> A. Select the Excel spreadsheet, table borders, with .a thin line. <br> B. in the CAD in edit choose Paste Special from the autocad entities. <br> C. Select the insertion point, you will find the inserted table line does not align with inverse select all of the vertical bar .(many horizontal lines have also been elected came in, next we will go to selected them), hold down the shift primary form, be careful not to put a vertical bar all packages in it, so the bar will be for you to chose, .now only a vertical line, and move his door alignment, trim to the upper-left corner of the root length, table art, and you manually one a line drawing, and then fill in the numbers of the same. <br> D. .it's not perfect, because the word size and your map is not unified, and now we have to solve the problem. Select a text in a table, look at his height, use the windows Calculator calculate it and you want to share the word, .how much worse the scale scale you want the text size. If you also want to set the width of the text, in order to produce the coefficient and you see in excel it alignment of data that the form is first defined as a block, the .block of time choose Insert x direction of the coefficient is the width of the text, all ok coefficient. <br> <br> 54. the system left key setting (from the left hand key new interpreting) <br> A £ ® mechanism .of left-handed key high speed: maybe we all know the Eagle shooting Heroes "in Zhou, this one will be about mutual Bo, unpredictable, fiction is fictional, it revealed the existence of truth is, Zhou will only draw party, left hand .right hand to draw a circle, at two things, but his key users are able to do all three, left hand right hand keyboard, mouse, be responsible for their own eyes staring at the screen coordinate of hands, here I am reminded that must .be left mangda, do not hurry, no accountability for its high-speed efficiency will not play, instead you reverse the tired mind! <br> B. the principles of left-handed key settings: you can no need to remember other people left .key code, that would not only increase your skill, but will tie you down, no matter what profession, what with the CAD system, you are drawing, certainly some of the commands used very frequently, you will most frequently ordered by Jane code located .on your left hand best key. setting simple code, it is best not to change the original CAD Jane Code, on the one hand, to facilitate others can use your CAD, on the other hand the default simple code as some friends said its a .great deal of truth in it, do not feel free to change it, I, for one, who can use my computer CAD, but others and myself, that's two-day-maybe someone will ask, that is, without changing the original code ., and to increase so much code, left key, there are so many empty keys? answer in the affirmative, careful consumer will find that the left hand key not defined in the second letter combination, complete the settings in your left hand Jane more. .in summary, the left hand key settings to strive to achieve a natural, more practical, more natural things, maybe it's integrated into some kind of philosophy. <br> C. left key settings: settings for Jane to have three ways: first, .it is the most common methods, complete in PGP, PGP files on different CAD version location, CAD2004 following version, you can install directory C: \ PROGRAMEFILES \ AUTOCAD2002 (2000) found in the \ SUPPORT folder, found in its original format to add .or modify, save shut down, start later when you can use CAD new sets of simple code; CAD2004 and above versions because looking for more complex, I recommend using the following the second method. In the words of PGP's advantage is that each time you .use the simple code, at the command line will display the full command letter, don't underestimate this fine, on preliminary design, NPC has the help of simple code, so you can do with side note, remember to completely avoid the memory burden ., the master, the disadvantage is that it is limited, only changed simple, it's not alone. <br> Second, in AUTOCAD interface directly increase the modification, this method only CAD2004 and above, in the CAD interface, open the "Tools / .Customize / edit custom file / program arguments (ACAD.PGP) "is opened, you will find a way of PGP is the same, increase modifications, run a command, check the REINIT PGPFILE marquee, the settings to take effect, restart the CAD .also take effect. <br> Third, be modified using LISP programs, why use LISP program to set Jane? this is because the former second method can only be general command, it is very limited, for example, I now have to use left .-handed "SW" keys at the same time directly from the TOP view into the Southwest view, can only help PGP, but LISP programs can accomplish this task, there are more interesting point is that the commands in AUTOCAD to compress the merge, youDon .'t worry you don't learn LISP programs, I give you three command format, with syntax description, your experience, carefully formatted as follows: <br> A. command simplified format (DEFUNC: Jane () (COMMAND "command") .<br> Example 1 using the Q key instead of a command LINE program (DEFUNC: Q () (COMMAND "LINE")) <br> B. command compression format (DEFUNC: Jane () (COMMAND "command" command line option ."command line option" command line option "" ")) <br> Example 2 uses SW key instead of entering the Southwest view command, program (DEFUNC: SW () (COMMAND"-VIEW "" SWISO ")) <br> .Example 3 lines with QC1 key combinations will be changed to the color style for 8, as the center point of the line, line styles for 1000 lines, program (DEFUNC: QC1 () (COMMAND "CHANGE" (SSGET) "", " .P "" LTYPE "" CENTER "," C "" 8 "" LTS "" 1000 """))< br> C. the command merge format (DEFUNC: Jane () (COMMAND" command a "command line option" .PAUSEPAUSE command II "" command line option """))< br> Example 4 for A4 key combinations that draw a quadrilateral and populates, the program is (DEFUNC: A4 () (COMMAND" POLYGON "," 4 "" E " .PAUSEPAUSE "HATCH" L "S" "" ""))< br> D. syntax descriptions: <br> DEFUN represents the defined function. <br> C: indicates that the command has nothing to do with the hard drive. < .br> SSGET paused, waiting for the user to select an action in real time, perform the following operations. <br> PAUSE Pause, waiting for the user to specify the point immediately after the subsequent operation. <br> "" To end the .selection <br> E. usage instructions: <br> From AUTOCAD installation folder, copy a LISP program, will empty the contents inside, and then press command of a variety of formats for writing is, note by analogy, the last loaded in AUTOCAD .(preferably in the startup group is also added, so that each CAD automatically when it starts to load), enabling use of AUTOCAD LISP programs increase in shortcuts also takes note of the second point, a modified with LISP is better than any other method to .modify the simple code simple code; the second is to use the LISP programs can modify CAD Jane Code, similarly to modify such days as the building, such as CAD-3D3S platform of numerous software simple code. You must by analogy to strengthen a flexible .application of the "enlightenment" in order to achieve "a sword, sword of million million normalized sword" sword, soon you will be seamlessly through the three-dimensional space, the building complex models can be anything you want, then you will feel a .bit lonely because you have entered the master. <br> <br> 55. clever Excel sketch curves in AutoCAD <br> In engineering calculations, often using AutoCAD to draw a curve, and the curve if is composed of multiple coordinate point connection, .enter up trouble, and error-prone. If you use EXCEL application to save data and CAD neatly together, you can easily draw the curve. Specific methods are as follows: <br> First, enter the coordinates in Excel. We will put the .x-coordinate value of A column, the y-coordinate values in the column b, and then add A merged columns a and b to C column, because the two-dimensional coordinates for the point in AutoCAD is separated by commas, so we entered .in cell C2: = A2 & "," & "in B2, C2 a pair of coordinates value. We use the mouse to drag the formula of the C2 for replication, you can get a set of coordinates. <br> Second ., choose the desired lines of point coordinate values, such as the above example C column data, copy it to the Clipboard, press the copy button in Excel to complete this work. <br> Finally, open the AutoCAD, at the command line, .type spline (draw a curve command), the prompt: "Object /", then in this location, click the right mouse button popup menu, select Paste command, so the coordinates in Excel is passed to the value of AutoCAD and automatically connected into .a curve, click the right mouse button, Cancel to continue drawing lines, curves and painted. <br> Through the above methods, you can easily draw various curves or polyline and Excel easily modify and save the coordinate values. <br> <br .>.
