<br> <br> 1. perform the Edit command, when prompted to select a target, choose the rectangular box, drag the cursor from left to right, the window Windows "mode, if you drag the cursor right to left; otherwise, ."cross-Cross", left and right selection difference is left frame selected must all be regarded as selected, while the right selection box on the entity as a small part is optional in the entity. <br> <br> 2. relative coordinates .input points, orthogonal, General @ x, 0, 0 or @ y (eg Enter relative coordinates "@ 100, 0," said a little bit on the relative increase of 100 X direction, and if input relative coordinate "@ 0, 50 ., "said a little bit Y direction relative increase 50), both of these cases, you can directly enter 100 or 50 you can achieve the same purpose, thus saving time. <br> <br> 3. in the AutoCAD sometimes cross mark .produced in the mouse, an order with BLIPMODE prompt line, enter OFF to remove it. <br> <br> 4. the user use AutoCAD will find command in the dialog box will prompt line, such as a print command, control, it .is a system variable CMDDIA, close it. <br> <br> 5. 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. <br> <br> .6.CMDECHO variable determines whether the resulting command line echo, its implementation in the program should be set to 0. <br> <br> 7.DIMSCALE determines the proportion of dimensioning, its value is an integer, default is 1, the graphics .have a certain scale should preferably be changed into a zoom percentage. <br> <br> Later versions of 8.CAD provides form and position tolerances, roundness and axiality enough round in circles, in fact, the definition of common symbols in AutoCAD are .AutoCAD installation directory SUPPORT child righteousness circular shape, the circle radian was 127 °, but not very good mend (such as read 90 ° more does not look good). <br> <br> 9. the hollow characters such as the use of .the BONUS features AutoCADR14-CAD2006 (be sure to fully install AutoCAD, or custom installation select it), there is a command that can be TXTEXP text fried as hollow characters <br> <br> One of 10.AutoCAD ARCTEXT command for arc text .output, use the method is first selected arc, then enter the text content, press OK. <br> <br> 11.BONUS has a useful command, that is, use it to MPEDIT multiple lines together to polylines, and then change its .width. <br> <br> 12.BREAK command to interrupt the entities, the user can also be a little disconnected entities, usage is on the first point to select, enter "α". Commonly used a line segment is dashed, another .solid, in 2000 later, enter the "F" from the point of interruption. <br> <br> Print line width 13.AutoCAD by color set, that mapping of various style, line width different lines can be placed in a different layer .to layer defines the style, color, and in the Print Setup settings line style and color of the relationship and the results were very good. <br> <br> 14.AutoCADR14 's Support for the default template in ACAD.dwt, processing .it, the commonly used layers, blocks, callout types defined, plus the standard figure box, you can save a lot of duplication of work, the current popular do a figure box CAD files, this file defines the layer block and callout types, in .the Insert picture box or other important information will be brought in .. <br> <br> 15. will insert AutoCAD graphics in a WORD, sometimes found round into a regular polygon, use a command, it VIEWRES is set too large, you .can change the graphic quality. <br> <br> <br> In the file as 16.AutoCAD block insertion in other documents, but so too many block so that the file is too large, use the PURGE to remove them, clear a .layer at a time, be sure to use a few times! <br> <br> 17. in the finished parts to assemble the parts after the welding block insert, and then open group group after Assembly, then use the Select command control group .ddselect is inscribed status, Cancel when you guess <br> <br> 18. in the menu source file in AutoCAD as a. mnu file and modify it to add your own commands to the menu, and then use the menu command to mount, .plus participate in AutoCAD help understand menu file format <br>. Icon on the toolbar to add your own commands for relatively simple, you can right-click on the point, in the toolbar, point to the new button, enter the tool bar, .a new tool bar, then choose Customize button, the selected custom, the empty button onto the toolbar, and then in the blank button on the right, so that you can define your own button image and commands. <br> <br> 19 .. AutoCAD status lines can also be defined at the DIESEL languages can access it, the easiest method to use when entering modemacro command to $ (getvar, clayer), beyond the current layer name is displayed in the accuracy of the line, the user of .it all! <br> <br> 20.AutoCAD graphics format. dwg, can also be exported as. bmp,. eps, and. wmf or. dxf, .3 ds, is if you use the render command can be saved as. .tga,. pcx,. tif format, AutoCAD you can also save the file directly to a format that you want to install to the system named "Rasterfileexport" printer, use it to print to a file, the file can also be ACAD2000 saved as .JPG format. <br> <br> <br>.
