24. 【 draw a rectangle or circle without the outside of the virtual box while AI Ah 】
A: the system variables can be resolved dragmodeON tick

25. 【 Drawing after you finish the ellipse, oval to polylines appear while AI Ah 】
Ellipse ellipse command is generated to polylines or ellipse to entity is determined by the system variable PELLIPSE, when its 1 PLINE ellipse is generated. 0, shows the entities

26. 【 mirror over the font remain the rotation while AI Ah 】
Mirrtext value of 0, you can keep the mirror over the font does not rotate, to 1, rotate

27. 【 square how to play out! 】
1T text command, enter the number 352, in front of enter SHIFT + 2, 6, and then press B/A key, this method is subscript

In 2 followed by SHIFT + 6, then press B/A key, this method as a superscript (or square)

28. 【 special symbol input 】
We know that the diameter of the "F", said plane "±", callout ° symbol "°" can be used to control code%% C,%,% P,%% D to enter the
But how to enter in the CAD Ah
1.T text command, drag a text box
2. in the dialog box right-------symbols------there will be some options

29. 【 print font is hollow while AI Ah 】
1. in the command line enter TEXTFILL command
A value of 0, the font is hollow. A value of 1 font is solid.

30. 【 off this layer, but you can still see the layers of certain objects causes 】
First of all, to explain what we mean by layers off why also display problem
For example, the "straight line"
The steps are as follows:
1. I have two sets of two lines (a total of four)
2. left this group of lines to CAD default color (A)
This group of lines on the right as a custom color (B), red, yellow, blue, any colour available (it is important to note that this set of lines to create a new layer)
3. are the two sets of lines to write blocks (W) command

Note: Although a block, but A set of lines is no layers of blocks, and B group lines with layers defined block

4. define block knot, remember the saved location to insert the
5. are the two groups tiles into the drawing interface
6. the establishment of two new layers, and then add two sets of lines respectively to the two new layer which
7. freezing given block
8. you will find that A item lines can be frozen B item lines cannot be frozen

Since we usually inserted blocks, mostly come from other parts of the exam and of most of the tiles are tiered building, it is not possible to carry out its overall close

Answer:

The crux of the problem is that your block (possibly others), which itself is in different layers to come. ] [Which itself is quite harmful! s so when you're on a layer for the ' off ', the ' frozen ', and so on appear when graphics from the command is invalid. The answer is: to find the map of blocks of the original file, open the map and changing it to all on the same layer, then the original figure block file another name. Turn your graphics, insert your new changing for the better of the tile, on a blank space, and then use this new tiles, fully replace the original figure block. At this time you can use the ' whole picture ' cleanup (Purge) command. This can be solved once and for all.
If you cannot find the original file, the other will teach you a trick: will your diagram you suspect blocks, copy one, put it in a blank space in the diagram. I suppose you call him a ' new-like ' then the ' new-like ' all in all entities into a layer, and then to the ' new-like ' as a block, in addition to name, and then use the ' new-like ' tiles for a global replace. This ensures your diagram does not have the old tiles, then you can use the Purge command.
I'm here to say method looks very trouble, in fact the only way to really solve the problem. This is actually the original author who carelessly doing dumb things, made CAD drawing of taboo
Namely: When do block can only be done on a layer (preferably 0 layer), you can use a different color, don't use different layers! actually a lot of people didn't notice the problem, I tell you, the hope of attracting attention.

31. 【 eliminate point marker 】
In AutoCAD sometimes cross marks are produced in the mouse, use BLIPMODE commands, and prompt, enter OFF to remove it.

32. 【 error file recovery 】
Sometimes we hard days of CAD drawings be drawn because of power outages or other reason suddenly can't open it, and there is no backup file, then we can try the following methods to restore:
1. in the "files (File)" menu select "drawing utility/repair (DrawingUtilities/Recover)" item in the pop-up "select file" dialog box (SelectFile)

In the select files to recover after confirmation, the system begins to perform the recovery file operation;
2. If you use the "Recover" command does not repair the file, you can create a graphic file, and then put the old figure used to insert the figure block in the new graphics, can solve the problem;
3. If there are problems of graphics file formats are R2000 R14 or or R2002 or R2004 next try above recovery operations;
4. in the open in 2004 AutoCAD2002 or after save as 2002 or 2004 file, and then reopen the file, and select use local animations, open several layers to save as a file, and then open the rest of the layers, and then save the second file, and finally copy the two files will coincide with the rehabilitation plan;
5. If you open a CAD drawing of a hundred numbers (e.g. 30%) would stop didn't reflect that this description of the drawings may not be damaged, put a computer in a non-AutoCAD provides vector font file delete (move to other places) and then try (reserved 2 ~ 3 can also be), maybe the file is opened correctly.

33. 【 sit the display three-dimensional coordinate 】
In the 3D view with dynamic changes the coordinates of the Viewer displays the direction to the command line type "-view" command, and then displays the command line:-VIEWinput option [?/orthogonal (O)/delete (D)/recovery (R)/save (S)/UCS (U)/Windows (W)]:
Type O and then return, you can return to the standard display mode.

34. 【 recovery failure characteristics match the command 】
Sometimes we use the AutoCADR14, additional commands are quite normal, but the characteristics match cannot be used to reload the software for a while and can't find it in installer, the following describes the way

You can come in handy.
Method 1. in the command line type menu command in the pop-up "select menu file dialog box, select the menu file acad.mnu, reload menu;
Method 2 in the command line type appload command in the pop-up "loading AutoLISPADS and ARX file dialog box, select and load AutoCADR14 match.arx file directory.
In fact, for other commands fail, you can also use the above method is flexible.
★: Brute-force method: find AutoCAD Directory match.arx or acmatch.arx files, use the mouse to drag and drop to ACAD drawing area. In fact, for other commands fail, you can also use the above method is flexible.

35. 【about explode command invalid issues 】
If the CAD, cannot explode tiles, first try can explode other entities (such as multiple lines of text, fill pattern, etc.), if the description is your selection of the entities themselves cannot be fried on (or in the command with. to test whether you can explode tiles); if not, you may be infected with a virus program AutoLISP language acad.lsp. Its main features performance to open any of the drawing can explode blocks that explode command is not valid, to our work has brought a lot of trouble. The virus is running on all opened CAD drawings of directory, build acad.lsp virus program, and the installation directory in the CAD Support, generate acadapp.lsp virus programs.

The following is clear the virus:
(1) open systems find "
File or folder "dialog box;
(2) in the "file or folder name" data box enter: acadapp.lsp acad.lsp;;
(3) in the"containing text" data box enter: explode;
(4) in the "search" in the data box, select: all hard drives;
(5) searches to these two files to delete all the problems have been solved.
Note: be sure to attach the hard drive is to search for all directories, so you can clean the virus.

* Added:

The virus file name may also be called Support\\acadiso.lsp

36. 【 how to save layers 】
Create a new CAD document, the layer, the callout style, and so on are set after save as DWT format (CAD template files).
In the install directory find CAD DWT template files folder, the DWT file you just created, later use, create a new document when prompted to select the template file selected that just fine, or, put the file named acad.dwt (CAD default template), replace the default template, then just open it.

37. 【 how to hide the coordinates 】
Sometimes you will catch some shots software CAD graphical interface or some similar play operation
But in the process, you are not for the coordinates of the lower-left corner of the depopulation
A: UCSICON adjustment reset to OFF
You can turn off, turn ON open

38. 【 junction marked on mouse click Department produces what? 】
A: use BLIPMODE command, enter at the prompt to remove it OFF.

39. 【 dimensioning tails have 0 while AI? 】
Examples:
If your mark is 100 mm
But in the graphics when a bid is 100.00 or 100.000 etc like this.

Then use the following command
"The best dimzin" system variable to set to 8, then the default values in the dimension does not end with a few zero, we directly enter the command to be modified very easily, no need to adjust the label options.
