60 practical CAD operation skills

1[The solution when Ctrl+N is invalid]

It is well known that CTRL+N is a new command, but sometimes CTRL+N will appear in the selection panel. In this case, you only need to adjust the settings in the OP option.

Operation: OP (option) - system - there is a start on the right side (A shows that the startup dialog box B does not display the startup dialog box). If A is selected, the new command is valid, but the reverse is invalid.

2 [Ctrl key invalid solution]

Sometimes we will encounter such problems, such as CTRL+C (copy), CTRL+V (paste) CTRL+A (select all), etc. A series of commands related to the CTRL key will be invalid, then you only need to go to the OP option. Tune in

Operation: OP (option) - user system configuration - WINDOWS standard accelerator (hook), after the standard accelerator button is checked, the command related to the CTRL button is valid, otherwise it fails;

3 [Solution when filling is invalid]

Sometimes it will not be filled when filling, in addition to the system variables need to be considered, you also need to check the OP option, OP-display - application entity fill (hook);

4[The solution when the selection is invalid]

The correct setting should be that multiple objects can be selected continuously, but sometimes, continuous selection of objects will fail, and only the last selected object can be selected. This can be solved as follows:

Enter OP (option) - select - SHIFT key to add to the selection set (to remove the tick), use the SHIFT key to add to the selection set "remove the tick" then the selection is valid, otherwise the selection is invalid;

Command: PICKADD Value: 0/1

5【CAD command three-key restore】

If the system variables in the CAD are inadvertently changed, or if some parameters are intentionally adjusted, then there is no need to reinstall or change one by one.

Operation: OP option - configuration - reset, you can recover. However, after recovery, some options require some adjustments, such as the size of the cross cursor;

6[What is the problem with the middle mouse button?]

Under normal circumstances, the CAD wheel can be used to zoom in and out, and it is to pan (press and hold), but sometimes, when the wheel is held down, it is not a pan, but a next menu, which is very annoying. At this time, you only need to adjust the system variable mbuttonpan to get the initial value: Support menu (.mnu) The action defined by the file supports panning when you hold down and drag the button or pulley.

7[CAD skills]

As we all know, there are two keys, one is "carriage return" and the other is "space", but now let us use the right button to replace them;

OP option - user system configuration - use the shortcut menu (tick) in the drawing area to customize the right button, click inside - put all the repeated previous commands on the test, right click is not a certain effect.

The first push: I hope everyone can develop a right button to determine this habit

Second: the space bar is second

Annoyance: Never use the Enter key to confirm

8[What should I do if the circle in the graph is not round?]

People who often make pictures will have such experience. The circle drawn is not round. Of course, those who have studied sketches know that the circle has a lot of fold lines combined. I won’t say much here, one command will fix it. , the command: RE can be.

9[Show scroll bar in graphics window]

Maybe someone still uses a mouse without a scroll wheel, then the scroll bar may have some effect (if the translation is not very useful);

Op-display - the scroll bar can be displayed in the graphics window;

10[Saved Format]

OP-Open and Save - Save as 2000 format, why save 2000 format? Because the CAD version is only backward compatible, it can be opened in 2002 2004 2006, which is convenient for operation.

11[What if I want to print the line type next time and this time?]

In other words how to save the print list, op option - print - add a print list, but before that, you have to create your own instance.

12. [If the path is not complete in the title bar, what should I do?]

Op option - open and save - display the full path in the title bar (check).

13[Target capture (OSNAP) useful?]

Very useful. Especially when drawing mechanical drawings with high precision requirements, target capture is the best tool for precise point determination. This is also very important to pay attention to, each version) D upgrade, the target capture function has been greatly improved. Do not use the cursor line to fix the point directly. Such a point cannot be very accurate.

14[Why is the hatching or dimensioning line drawn not a continuous line type?]

The hatching and dimensioning drawn by AutoCAD can have linear attributes. If the current line type is not a continuous line type, the hatched lines and dimensions drawn will not be continuous lines.

15[How to reduce file size]

After the graphics are finished, execute the Cleanup (PURGE) command to clean up the extra data, such as useless blocks, unstructured layers, unused linetypes, fonts, and size styles, which can effectively reduce the file size. General thorough cleaning requires PURGE two or three times. "-purge", with a minus sign in front, the cleaning will be more thorough

★Supplement: Use the WBLOCK command. Use the WBLOCK command to generate a new graphic file in block mode and use the newly generated graphic file as a transfer or archive. So far, this is the most effective "weight loss" method I have found. A concise example is as follows:

Command: "wblock" (Enter the file name and file storage location in the pop-up dialog box. Since it is very simple, the dialog box graphic is omitted here)

Defined name: (direct carriage return);

Give a base point: (optional);

Select an object: (Enter after the selection is completed);

This will generate a new graphic file in the folder you specified.

The author used two methods to streamline and compare the effects of his DWG file. The reduced file size is almost within 5K.

16[How to restore automatically saved graphics]

AutoCAD stores the automatically saved graphics in the AUTO.SV$ or AUTO?.SV$ file, and finds the file and renames it to a graphic file to open in AutoCAD. Generally, this file is stored in the temporary directory of WINDOWS, such as C:\WINDOWS\TEMP;

Added: *.sv$ file storage location by default: win9x: Generally this file is stored in the temporary directory of WINDOWS, such as C:\WINDOWS\TEMP; winnt/2000/xp:

Start menu -> Run, enter %temp%, (possibly %tmp% is also OK), OK.

17[Why can't I display Chinese characters? Or the input Chinese characters become a question mark]

reasons may be:

1. The corresponding font does not use Chinese fonts, such as HZTXT.SHX;

2. There is no Chinese font font in the current system; the shape file used should be copied to the AutoCAD font directory (usually...\FONTS\);

3. For some symbols, such as Greek letters, you must also use the corresponding font shape file, otherwise it will be displayed as? number.

If you can't find the wrong font, or your eyes are not very good, the temper is a little anxious, then you can set the correct font and size, write a new one, and then use the small brush to click the newly entered font to brush the wrong font. Can be slightly.

Note: The system has some built-in fonts, but sometimes it is a big inconvenience caused by the wrong operation or some external factors, which will cause you a lot of inconvenience. Then you go to someone else's computer and test some fonts. It’s OK

18[Why the height of the input text cannot be changed]

When the height value of the font used is not 0, the height is not prompted when writing text with the DTEXT command, so the height of the written text is constant, including the dimensioning using the font.

19[Why can some graphics be displayed but not printed?]

This can happen if the graphics are drawn on AutoCAD's automatically generated layers (DEFPOINTS, ASHADE, etc.). Should avoid these layers, know no.

20[What should I do if the DWG file is destroyed?

File - Drawing Utility - Repair. Select the file you want to repair. This method is effective at 50%, and some people will use find. However, if you have automatic save, in some cases, for example, after a power outage, the computer has a UPS. If you want to do something, it is recommended to manually back up immediately. Do things again. Otherwise, sometimes it will be saved automatically. It will be out of power. It will be finished. It can't be repaired. Because it only saves half of it, it will be turned off. Don't believe it. Don't believe it.

21 [What if you want to modify the block]

A lot of people thought that they couldn't modify the block, and then blasted it up. Then they changed the definition in the merger and it was not sick. I am optimistic about the modify block command: REFEDIT, follow the prompts, modify the command with the command: REFCLOSE, confirm the save, your original change will also be saved.

22[Simplified two printing methods]

There are two kinds of printing: model space printing; the other is layout space printing, you say a box, a box of printing is model space printing, which requires inserting a frame for each individual graphic. Then, according to the size of the figure, the frame is zoomed: floor plan, floor plan, ceiling view, floor plan, face view...etc. This is very slow when you draw the picture.

Batch printing can be achieved if layout printing is used, no plug-ins are required;

1) Switch to the layout, set the page (paper size, or the margins around, etc.);

2) Delete the original image;

3) Insert a 1:1 frame (make sure you have this box);

4) view viewport, drag the original map;

5) Define the scale, for the graphics (command: Z space S space), then use the MS or PS command to switch between the box and the outside of the box;

6) Z empty S is empty, if the ratio is given then the ratio of your map is 1/1.

The above is to print a picture in order to make it clear to you, we set the above picture for the next operation for all the pictures, the key is here, look carefully:

1) Right click on the layout and select Move or Copy. A dialog box will appear. You will check the “Copy” and move it to the end. Of course, this depends on the order in which you are drawing. You can customize this time. Another copy appears, which is a copy of the X graphic. At this time, you use the MS command to switch to the box. Use the P translation command to find the second graphic you want to print, and then scale it. If the graphics are the same, I am Say, if the X picture is a plane, this picture is a ceiling, I don't think the ratio is adjusted, because it is the same size.

2) The PS command switches to the outside of the box, and the Z space E space is maximized. I feel that the graphics are suitable if they are not suitable for adjustment.

3) The next operation is the same, that is, copy the copy.

Note: You have to draw all the drawings in a model space so that you can print in batches.

23. [What to do if there is no outside virtual frame when drawing a rectangle or a circle]

This problem is also more common, the system variable dragmode ON check can be solved.

24. [After drawing the ellipse, what should the ellipse display as a polyline?]

Whether the ellipse generated by the ellipse command is a polyline or an ellipse is determined by the system variable PELLIPSE. When it is 1, the generated ellipse is PLINE. (When 0, the entity is displayed)

25 [How to do if the mirrored font remains unrotated]

When the value is 0, the mirrored font can be kept from rotating.

1 o'clock, rotate

26[How do you square it?]

1T text command, enter the number 35

Enter SHIFT+6 in front of 2, then press B/A, this method is subscript

Enter SHIFT+6 after 2, then press B/A. This method is superscript (ie square)

27【Input of special symbols】

We know that the "Ф" indicating the diameter, the "±" indicating the ground plane, and the symbol "°" can be input with the control code %%C, %%P, %%D, but input in CAD.

T text command, drag out a text box (don't tell me you won't take it off);

2. Right-click on the dialog box - some options will appear.

28[What is the printed font is hollow?]

When the TEXTFILL command value is 0 on the command line, the font is hollow. A value of 1 makes the font solid. OK, solve

29 [After turning off this layer, you can still see the cause of some objects in this layer]

Let me take a moment to explain why we are talking about why the layer is closed.

For example, "straight line":

The steps are as follows:

1) draw two sets of two straight lines (four in total)

2) The left line is the CAD default color, and the right line is the custom color (B), red, yellow, blue, any color (need to be explained, create a new layer for this group of lines)

3) Write the block (W) command for the two sets of lines respectively. Note: Although both are blocks, the A group lines are non-layer blocks, and the B group lines are layers with layer definition.

4) After defining the block, remember the saved location for insertion

5) Insert two sets of tiles into the drawing interface respectively, create two new layers, and then put the two sets of lines into the two new layers respectively to block the block freeze. You will find that the A item lines can be frozen, B items. Lines can't be frozen, because most of the blocks we insert on time are taken from other places, and most of the tiles are layered so they can't be closed.

The key to the problem is the block you are using (possibly someone else's), which itself is made on different layers. [This is quite harmful in itself! 〕 So when you are doing a 'close', 'freeze' operation on a layer, the graph seems to show that the command is invalid. The solution to the problem is to find the original file of the tile, open the image, and change it to be on the same layer, and then rename the original tile file. Reopen your drawing, insert your newly modified tile, place it in a blank space, and then use this new tile to completely replace the original tile. At this time you can use the 'Purge' command. This can be solved once and for all.

If you can't find the original file, here's another trick: copy one of the blocks you suspect in your picture, and put it in a blank space in the picture. I assume that you call him a 'new sample' and then change all the entities in this 'new sample' to a certain layer, then use this 'new sample' as a block, and name it again, then use the 'new sample' block. Make a global replacement. This will ensure that there are no old tiles in your diagram, then you can use the Purge command. )

The method I am talking about here seems to be very troublesome. In fact, only by doing this can the problem be solved. This situation is actually the author of the original picture is clever, doing stupid things inadvertently, and committing the taboo of CAD drawing:

That is: when doing the block, you can only do it on one layer (preferably 0 layer), you can use different colors, don't use different layers!

30【Remove point mark】

In AutoCAD, sometimes cross-point marks are generated at the click of a mouse. Use the BLIPMODE command and enter OFF at the prompt line to eliminate it.

31 [Recovery of error files]

Sometimes the CAD drawings we have worked hard for a few days will suddenly fail to open due to power outages or other reasons, and there is no backup file. In this case, we can try the following methods to recover:

1) Select the "Drawing Utilities/Recover" item in the "File" menu, select the file to be restored in the "Select File" dialog box that pops up, and confirm the system. Start performing a recovery file operation;

2) If you can't repair the file with the "Recover" command, you can create a new graphic file, and then insert the old image into the new graphic in the form of a tile, which can also solve the problem;

3) If the problematic graphic file is in R14 or R2000 format, you can also try the above recovery operation under R2002 or R2004;

4) After opening in AutoCAD2002 or 2004, save the file as 2002 or 2004, then reopen the file, and select to use partial open mode, open several layers and save as a file, then open the remaining layers with &n9j/ Save as a second file, and finally copy the two files together to restore the map;

5) If you open a certain number of CAD drawings (such as 30%), it stops and does not reflect. This means that the drawings are not necessarily damaged. Delete the vector font files provided by non-AutoCAD in the computer (move to other places) Try again later (retain 2 or 3 can also be), and maybe the file will open normally.

32 [Display of 3D coordinates]

After changing the direction of the coordinate display with the dynamic viewer in the 3D view, you can type the "-view" command on the command line, and then the command line displays: -VIEW Input Options [?/Orthogonal (O)/Delete (D)/ Restore (R) / Save (S) / UCS (U) / Window (W)]: Type O and then press Enter to return to that standard display mode.

33 [Recovery invalid feature matching command]

Sometimes in the use of AutoCAD R14, other commands are normal, but the feature matching can not be used, reinstall the software can not find its installation program, the method described below can come in handy.

Method 1. Type the menu command at the command line. In the pop-up "Select Menu File" dialog box, select the acad.mnu menu file and reload the menu.

Method 2. Type the appload command at the command line. In the pop-up "Load AutoLISP ADS and ARX File" dialog box, select and load the match.arx file in the AutoCAD R14 directory.

In fact, the above methods can be flexibly used for other commands that fail.

Violent cracking method: Find the match.arx or acmatch.arx file in the AutoCAD directory and drag it directly to the ACAD drawing area with the mouse. In fact, the above methods can be flexibly used for other commands that fail.

34 [About the invalid explode command]

If you can't blast the tile during the use of CAD, try to open other entities (such as multi-line text, fill patterns, etc.). If you can, the entity you selected cannot be fried. On (you can also add a . before the command to test whether you can blast the tile); if not, it may be infected with a virus program acad.lsp based on the AutoLISP language. Its main performance feature is that opening any of the drawings can not open the block, that is, the explode command is invalid, which brings a lot of trouble to our work. The virus will generate the acad.lsp virus program in all the directories where the CAD drawings are opened, and generate the acadapp.lsp virus program under the CAD installation directory Support.

Here's how to clean up the virus:

1) Open the system to find the "File or Folder" dialog box;

2) In the "File or Folder Name" data box, enter: acad.lsp; acadapp.lsp;

3) In the "Include text" data box, type: explode;

4) Select in the "Search" data box: all hard drives;

5) After deleting all the two files found, the problem has been solved.

Note: Be sure to search all directories on your hard drive to clean up the virus.

★Addition: The name of the virus file may also be called Support \ acadiso.lsp

35[How to save a layer]

If you want to set the layer, label, and print, save it!! It is convenient to make the map next time.

How to operate, simply say:

Create a new CAD document, set the layer, label style, etc., and save it as DWT format (CAD template file). Find the folder where the DWT template file is placed in the CAD installation directory, and put the DWT file you just created into it. When you use it later, you will be prompted to select the template file when you create the new document. Or, just name the file acad. Dwt (CAD default template), replace the default template, just open it later. Of course there are other ways.

36 [How to hide coordinates]

Sometimes you will have some screenshot software to capture the CAD graphical interface or perform some similar operations (but in the process, are you worried about the coordinates of the lower left corner? Because it exists, it affects your operating.

UCSICON is set to OFF, which can be turned off and ON is turned on.

37[What should I do if the cross mark is generated at the mouse click?

Sometimes there are cross-point marks in the drawing that are generated at the click of the mouse, which is very annoying (use the BLIPMODE command, enter OFF at the prompt line to eliminate it.

38[What should I do if the intersection mark is generated at the mouse click?

Sometimes there are cross-point marks in the drawing that are generated at the click of the mouse. It is very annoying. Use the BLIPMODE command to enter OFF at the prompt line to eliminate it.

39. [What should I do if the marked tail has 0]

For example: If you mark it as 100MM, but the actual mark in the figure is 100.00 or 100.000, etc., then use the following command,

The "dimzin" system variable should be set to 8 at this time. The default value in the dimension will not have a few tail zeros. It is convenient to directly input this command to modify it. It is not necessary to adjust it in the labeling option.

40[What if I want to insert a CAD drawing into WORD]

Word document production often requires various illustrations. Word drawing has limited functions, especially complex graphics. This shortcoming is more obvious. AutoCAD is a professional drawing software, powerful, very suitable for drawing more complex graphics, drawing graphics with AutoCAD. Then insert Word to make a composite document is a good way to solve the problem, you can use the EXPORT function provided by AutoCAD to first export the AutocAD graphics in BMP or WMF format, then insert the Word document, or you can copy the AutoCAD graphics to the clipboard first, then Paste in the Word document. It should be noted that since AutoCAD default background color is black, and Word background color is white, you should first change the AutoCAD graphic background color to white. In addition, when AutoCAD graphics are inserted into a Word document, the margins are often too large and the effect is not satisfactory. Use the cropping function on the Word image toolbar to trim, and the problem of too large a margin can be solved.

41[What if I want to insert EXCEL]

I tried this method, and I will try it out. I hope that there will be a more convenient and quick way for the high person to provide.

AutoCAD form production:

Although AutoCAD has powerful graphics functions, the table processing function is relatively weak. In actual work, it is often necessary to create various forms in AutoCAD, such as engineering quantity tables. How to make tables efficiently is a very practical problem.

Drawing the table by hand drawing in the AutoCAD environment, and then filling in the text in the form, not only inefficient, but also difficult to precisely control the writing position of the text, text layout is also very problematic. Although AutoCAD supports object linking and embedding, it can be inserted into Word or Excel tables, but on the one hand it is not very convenient to modify. A little modification has to go into Word or Excel. After the modification is completed, it has to be returned to AutoCAD. On the other hand, Some special symbols, such as the first-level steel symbol and the second-level steel symbol, are difficult to input in Word or Excel. So is there a way to achieve the best of both worlds? After exploration, it can be better solved: first form the form in Excel, copy it to Clipboard, and then select the optional sticky towel in the Edit menu in the AutoCAD environment, select as. . . After confirming, the form is converted into an AutoCAD entity, and it is very convenient to use the explode to explode, which can edit the lines and square characters.

42 [Paths and techniques to improve drawing efficiency]

How to improve the speed of drawing, in addition to some commands we need to master, but also follow certain drawing principles, in order to improve the drawing speed, users should follow the following mapping principles:

1) Mapping steps: Set the frame → set the unit and precision → create several layers → set the object style → start drawing.

2) Drawing always uses a 1:1 ratio. To change the size of the pattern, you can set different print ratios in the paper space when printing.

3) Set different layers, colors and line widths for different types of primitive objects, and the color, line type and line width of the primitive objects should be controlled by the layer (BYLAYER).

4) When you need to draw accurately, you can use the grid snap function and set the grid snap spacing to the appropriate value.

5) Do not draw the frame and the graphic in the same picture. Insert the frame into the block in the layout (LAYOUT) and print out the picture.

6) For well-known objects, such as views, layers, tiles, line styles, text styles, print styles, etc., naming should not only be concise, but also follow certain rules for easy searching and use.

7) Set some common settings, such as layer, dimension style, text style, grid capture, etc. in a graphic template file (ie saved as *.DWF file), and then create a new graphic when drawing a new image later. Click "Use Template" in the wizard to open it and start drawing.

Choose the right command

The user is able to navigate AutoCAD by issuing a series of commands to it. When AutoCAD receives a command, it immediately executes the command and completes its corresponding function. In the specific operation process, although there are many ways to achieve the same purpose, if the command is properly selected, the operation steps will be significantly reduced, and the drawing efficiency will be improved. Below are just a few of the more typical cases.

1) Generate a line or line segment

(1) In AutoCAD, lines or segments can be generated using the LINE, XLINE, RAY, PLINE, MLINE commands, but only the LINE command has the highest frequency and is the most flexible.

(2) In order to ensure the correspondence between "long alignment, width equal, high level" between the three views of the object, XLINE and RAY commands should be used to draw several auxiliary lines, and then TRIM cuts off the excess parts.

(3) To quickly generate a closed fill boundary, or to construct a region, use the PLINE command. Line segments generated with PLINE can be edited with the PEDIT command.

(4) When a plurality of line segments parallel to each other are generated at a time, and each line segment may use a different color and line type, the MLINE command may be selected.

2) Comment text

(1) When using text comments, if the text in the comment has the same format and the comment is short, use the TEXT(DTEXT) command.

(2) When you need to write large paragraphs of text, and the text in the paragraph may have different formats, such as font, word height, color, special symbol, formula, etc., you should use the MTEXT command.

3) Copy graphics or features

(1) In the same graphic file, if the graphic is only copied once, the COPY command should be used.

(2) In the same graphic file, if you want to copy a graphic at random, you should use the MULTIPLE (option) option of the COPY command; or use the COPYCLIP (normal copy) or COPYBASE (specify base copy) command to display the required graphic. Copy to the clipboard and then paste to multiple specified locations using the PASTECLIP or PASTEBLOCK commands.

(3) In the same graphic file, if the copied graphics are arranged according to a certain rule, such as forming a number of rows and columns, or evenly distributed along a circumference (arc), the ARRAY command should be used.

(4) In the same graphic file, if you want to generate multiple lines that are parallel to each other, equally spaced or unequal, or generate a series of concentric ellipse (arc), circle (arc), etc., you should use the OFFSET command.

(5) In the same graphic file, if the number of copies to be copied is quite large, in order to reduce the size of the file, or to facilitate uniform modification in the future, the specified graphic should be defined as a block with the BLOCK command, and then the block is selected by the INSERT or MINSERT command. Just plug it in.

(6) Copying graphics between multiple graphic documents can be done in two ways. First, use the command operation. First copy the graphic to the clipboard using the COPYCLIP or COPYBASE command in the open source file, and then copy the graphic to the specified location using one of PASTECLIP, PASTEBLOCK or PASTEORIG in the open destination file. This is equivalent to selecting the appropriate option in the shortcut menu. Second, use the mouse to directly drag the selected graphics. Note: Dragging in the same graphic file can only be a moving graphic, while dragging between two graphic documents is a copying of the graphic. When dragging, the mouse pointer must point to the line of the selected graphic rather than to the pinch of the line. Also note that there is a difference between dragging with the left button and dragging with the right button. Use the left button to drag and drop directly, and when you drag and drop with the right button, a shortcut menu will pop up, and you can choose different ways to copy according to the options provided in the menu.

(7) To copy graphic features between multiple graphic documents, the MATCHPROP command should be used (matching with the PAINTPROP command).

Use Express Tool (EXPRESS TOOLS)

The so-called express train tool is actually a utility library designed for users and provided free of charge with AutoCAD 2000. Most of the tools in the library come from the AutoCAD R14 Bonus tool, and the rest have been abandoned or improved, with new tools added. Express tool has extended the functions of AutoCAD in many aspects such as layer management, object selection, input/output of dimensioning style, editing and editing of graphics, etc., and can be easily combined in AutoCAD 2000 menus and toolbars. Convenient and fast, it can significantly improve the efficiency of your drawing.

The way to install the express tool is to select "Full" installation when installing AutoCAD 2000, or select "User" installation with the "Express Tool" option. If this is not the case, you should reinstall AutoCAD 2000 in "add" mode and select the "Express Tool" to be added.

By default, AutoCAD 2000 does not load the express tool into memory at startup to reduce its startup time. The tool library is automatically loaded when you first use the express tool. However, you can also force the load with the EXPRESS TOOLS command at the beginning. If the "Express" menu does not appear on the screen if the Express Tool is properly installed, you can use the EXPRESS MENU command to display the menu.

Here's how to display the "Express" toolbar on the screen:

(1) In the drop-down menu, select View > Toolbars... and the "Toolbars" dialog box appears.

(2) In the drop-down combo box named "Menu Group", select "Express".

(3) Click on the desired option in the combo box named "Toolbar". Any option with an "X" will display its toolbar on the screen.

(4) Click the "Close" button to exit the dialog.

Turn some visual elements on or off

The complexity of the graphics affects the speed at which AutoCAD executes commands and refreshes the screen. Turning on or off some visual features (such as fills, wide lines, text, marker points, highlight selections, etc.) enhances AutoCAD performance.

(1) If FILL is set to OFF, the solid fill mode is turned off, newly drawn traces, polylines with widths, filled polygons, etc., only one outline is displayed, which are not output when printed. The effect of the fill mode on existing graphics can be displayed using the REGEN command. In addition, the system variable FILLMODE controls the display of all hatching in addition to controlling the fill mode.

(2) Turn off the wide line display. The wide line increases the width of the line. Wide lines are output as actual values ​​when printed, but are displayed in pixel scale in model space. When using AutoCAD drawing, the wide line display can be turned off with the LWT button on the status bar or by selecting the "Wide Line" option from the "Format" menu to optimize its display performance. The system variable LWDISPLAY also controls the wide line display in the current drawing.

(3) If QTEXT is set to ON, the fast text mode is turned on. In this way, the newly added text in the drawing will be hidden and only display a border, as will the printout. This setting affects existing text and can be displayed using the REGEN command. In addition, the system variable QTEXTMODE also controls whether the text is displayed. When the text in the pattern is large, the impact on system performance is obvious.

(4) It is forbidden to display marked points. The so-called marker points are temporary markers that appear in the AutoCAD drawing area when selecting a graphic object or positioning a point. They can be used as reference points and can be cleared with the REDRAW or REGEN commands, but they do not appear on the drawing when printed out. To disable the display of marker points, set BLIPMODE to OFF to enhance the performance of AutoCAD.

(5) Cancel the highlight selection. By default, AutoCAD uses "highlight" to indicate which graphic is currently being selected. However, changing the value of the system variable HIGHLIGHT from 1 to 0 also enhances AutoCAD performance when the highlight selection is cancelled.

(6) By the way, setting the value of the system variable REGENMODE to 0, or setting REGENAUTO to OFF, can save time for automatic image re-generation.

Clean up the graph in time

There may be some useless objects in a graphics file that are not used, such as layers, tiles, text styles, dimension styles, line styles, and so on. These useless objects not only increase the size of the file, but also reduce the performance of AutoCAD. Users should use the PURGE command to clean up in time. Because graphic objects are often nested, it is often necessary for users to use the PURGE command several times in order to clean up useless objects.

Use command aliases and accelerators

AutoCAD defines aliases and accelerators for some of the more commonly used commands or menu items. Using command aliases and accelerator keys can significantly save time accessing commands. The command alias is defined in the acad.pgp file. You can add, delete, or change a command alias by opening and editing the file with any text editor. Alias ​​defined in this way can be used when re-entering AutoCAD. In the latest software release, users can redefine the command alias with the Express tool without having to exit AutoCAD, but if you use this method, you need to execute the REINIT command to reinitialize the software before using the newly defined alias for the first time.

The command accelerator key is defined in the acad.mnu file. To add, delete, or change the command accelerator, the user can only edit and modify the acad.mnu file with a text editor. The modified *.mnu file must be loaded and compiled with the MENU command, and the newly defined command accelerator key can be used.

CAD passwords: autocad2004 and above.

Step 1: Save the file to be encrypted. In the Save dialog box that appears, select Tools in the upper right corner and select the security options under it.

Step 2: Enter your password in the input box under Password... in the dialog that opens.

Step 3: After the second step is confirmed, the password confirmation dialog box will appear. Enter the password you just entered again. The two inputs must be identical. Once you are sure your files are encrypted. Enter the password when you open it again. Forgot the password file will never open, so it is best to back up the file before encryption.

43[There is no dialog box, just how to display the path?]

When you press CTRL+O or CTRL+S, no dialog box appears, just how to display the path.

Command: FILEDIA is set to 1.

44[How do I print when I print?]

打开打印机的对话框中(askcad.com),为工程师增加动力，右侧有一个打印戳记，把它前面的对勾去掉就可以了。

45【CAD2002以上版本在哪里修改快捷键】

如果你正在使用的系统是Win2000或者WInXP的话，请到这个位置去查找PGP文件"XX(你的系统安装盘):\Documents and Settings\(你的用户名)\Application Data\Autodesk\AutoCAD 2006(或者是2002/2004/2005/2006)\R16.2(CAD内部版本号，可能是R15.1/R16.1等)\chs(中文版，英文版好像是ENS不记得了)

46.【添加程序中大面积的空白怎么解决呀】

解决办法是修改注册表

运行regedit.exe，到HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall，查找"AutoCAD 2002" 应该是在{5783F2D7-0101-0409-0000-0060B0CE6BBA}里，（也可能不能完全对应这些数值）然后双击右边的DisplayIcon项，把最后的数字改为0（原来是-1）。

47【ma的小问题】

有的时候用MA这个小刷子刷物体的时候。不能刷其线型，或颜色等，MA-选中源对像-S设置-这里把想刷的打上勾即可。

48【文字乱码小办法】

命令:FONTALT （用于字体的更换）。

解决CAD字体乱码现象：

工作需要用cad读取大量的各大设计院的cad图纸,大家可以把以下这段添加到cad目录下的acad.fmp文件中,解决在读取cad无这种字体下造成的乱码现象,如遇到没有添加的，大家可以自行添加,希望能给大家一点帮助。

49【解决AutoCAD在XP操作系统下打印时致命错误的方法】

近来，AutoCAD 2002 版或2004版本在点击打印时出现致命错误并退出AutoCAD的现象。经过的研究，这跟AutoCAD 2002及以上版本使用打印戳记有关。在2000版时，增补的打印戳记功能就有很多的BUG，这个功能在2002版本后就直接做为AutoCAD功能。该功能在98操作系统中是完全没有问题的，但在有些XP系统中就会出错。所以在XP系统中最好不要去开启该功能。

如果你已经不幸开启了该功能而使AutoCAD在打印时出现致命错误，解决的方法只能是这样：在AutoCAD的根目录下找到AcPltStamp.arx文件，把它改为其它名称或删除掉。这样再进行打印就不会再出错了，但也少了打印戳记的功能。该方法对于2002版及2004版均有效。

50【ACAD.PGP文件修改】

大家都知道LINE命令在COMMAND输入时可简化为L，为何会如此呢？因为在AutoCAD中有一个加密文件ACAD.PGP中定义了LINE命令的简写，先找出这个文件打开它。找到"These examples include most frequently used commands."的提示语，在其下的几行文字就可对简写的定义，记住它的左列是简写命令的文字实现你可以根据你的需要进行修改（当然是你比较熟悉的英文缩写喽），它的右列是默认的命令请不要随意修改。相信这能为你提高一定的速度。

51【对图形夹点操作】

夹点，你用过吗？当你用鼠标左键点击图形，图形上便会出现许多方框这些就是夹点。通过控制夹点便能进行一些基本的编辑操作。如：COPY，MOVE，改变图形所在的图层等基本操作。而且不同的图形，还有其特殊的操作。如：直线有延伸操作.

52【关于鼠标的一点小技巧】

在acad.mnu中做上面的设置你只要按住shift键然后击鼠标，右键就可以框选放大(zoom w)，按住ctrl键然后击鼠标右键就可以回到上一次图形窗口(zoom p)，当然了，有兴趣的朋友玩玩行，实际用处不是很大。

53【鼠标都有啥功能呀】

54【块文件不能炸开及不能用另外一些常用命令的问题】

可以有两种方法解决，一是删除acad.lsp和acadapp.lsp 文件，大小应该一样都是

然后复制acadr14.lsp两次，命名为上述两个文件名，加上只读，就免疫了。要删掉你DWG图形所在目录的所有lsp文件。不然你会感染别人的。 二是有种专门查杀该病毒的软件。

55【删除顽固图层的有效方法】

删除顽固图层的有效方法是采用图层影射，命令laytrans，可将需删除的图层影射为0层即可，这个方法可以删除具有实体对象或被其它块嵌套定义的图层，可以说是万能图层删除器。

56【CAD 自动保存的文件格式转化为DWG格式时，为什么总会变成.DWG.SV$格式】

那是你的文件扩展名被隐藏起来了。在IE浏览器菜单“工具”－“文件夹选项”－“查看”中先去除“隐藏已知文件类型的扩展名”再重命名sv$文件。

57【在修改完ACAD.LSP后，它不能自动加载怎么办】

每次新建文档或者打开AUTOCAD都必须手动加载ACAD.LSP文件，若要想每次启动或者新建都能自动加载LISP文件， e那么可以将ACADLSPASDOC的系统变量修改为1。

★补充：ACADLSPASDOC的含义是这样的：

0 只在开第一张图的时候加载acad.lsp1 每次开图均重新加载acad.lsp

只要acad.lsp的路径正确，每次打开CAD，它至少会被自动加载一次，然后才归ACADLSPASDOC干活。路径正确的意思，是放到支持文件搜索路径里面。简单说，cad根目录、support和当前工作目录最保险。

58.【如何关闭CAD中的*BAK文件】

1）工具——选项，选“打开和保存”选项卡，再在对话框中将“每次保存均创建备份”即“CREAT BACKUP COPY WITH EACH SAVES”前的对钩去掉。

2）也可以用命令ISAVEBAK,将ISAVEBAK的系统变量修改为0，系统变量为1时，每次保存都会创建“*BAK”备份文件。

59【CAD中绘图区左下方显示坐标的框有时变为灰色，当鼠标在绘图区移动时，显示的坐标没有变化怎么办】

这时需按F6键或者将COORDS的系统变量修改为1或者2。

系统变量为0时，是指用定点设备指定点时更新坐标显示。

系统变量为1时，是指不断更新坐标显示。

系统变量为2时，是指不断更新坐标显示，当需要距离和角度时，显示到上一点的距离和角度。

60【当绘图时没有虚线框显示，比如画一个矩形，取一点后，拖动鼠标时没有矩形虚框跟着变化】

这时需修改DRAGMODE的系统变量，推荐修改为AUTO。

系统变量为ON时，再选定要拖动的对象后，仅当在命令行中输入DRAG后才在拖动时显示对象的轮廓。

系统变量为OFF时，在拖动时不显示对象的轮廓。

系统变量位AUTO时，在拖动时总是显示对象的轮廓。
