11. The difference between adding "-" before the command and not adding "-":
"-" and not adding "-" have different meanings in AUTOCAD. Adding "-" is a compatible command developed after AUTOCAD2000 in order to have a unified writing method for commands in various language versions.
Adding "-" before the command is the command line mode of the command. If not, it is the dialog mode. To be more specific: after adding "-" in front of the command, the dialog mode will not appear when the command is run. All The commands are all entered on the command line. When the command is run without adding "-", a dialog box will appear, and the parameters are entered in the dialog box.

13. After modifying ACAD.LSP, it cannot be loaded automatically. Every time you create a new document or open AUTOCAD, you must manually load the ACAD.LSP file. If you want to load it automatically every time you start or create a new file, LISP file, then you can modify the ACADLSPASDOC system variable to 1.

In this case, you need to press the F6 key or change the COORDS system Change the variable to 1 or 2.
When the system variable is 0, it means that the coordinate display is updated when a pointing device is used to specify a point.
When the system variable is 1, it means that the coordinate display is continuously updated.
When the system variable is 2, it means that the coordinate display is continuously updated. When distance and angle are required, the distance and angle to the previous point are displayed.
23. When there is no dotted frame displayed when drawing, for example, when drawing a rectangle, after taking a point, no rectangular dotted frame changes when the mouse is dragged. At this time, the system variable of DRAGMODE needs to be modified. It is recommended to change it to AUTO. .
When the system variable is ON and the object to be dragged is selected, the outline of the object will be displayed during dragging only when DRAG is entered in the command line.
When the system variable is OFF, the outline of the object is not displayed when dragging.
When the system variable is set to AUTO, the outline of the object is always displayed when dragging.

31. Transparent command, you can see this word in many places on the forum. The so-called transparent command means entering and executing the command on the command line while running other commands. Transparency commands are mostly commands to modify graphics settings, or to open drawing auxiliary tools, such as snap, grid, or zoom.
To use a command transparently, enter a single quote "'" before entering the command. In the command line, there is a double dash "〉〉" before the prompt of a transparent command. After the transparent command is executed, the original command will continue to be executed.
However, during the process of transparent use of a command, other transparent commands cannot be used, which means that transparent commands cannot be nested.
32. To set the drawing units, the command is units, and the menu command is format--units. After executing this command, the drawing units dialog box will pop up. In the dialog box It contains four areas: length, angle, graphic unit of design center block and output sample. You can make corresponding settings. Clicking the direction button will pop up the direction control dialog box. In this dialog box, you can set the reference angle direction. The default is 0 degrees east.
33. Interchange of windows , at work, sometimes we open several graphic files at the same time. It is troublesome to click the window with the mouse and then find the file to be opened. In CAD, you can use ctrl+f6 or ctrl+tab to exchange windows, but It should be noted that the input method at this time must be the English input method.

36. When copying objects, you always need to enter M for multiple copies, which is more troublesome. You can add a program in the acad.lsp file to avoid entering M. My usage is:
(defun C:CVV ()
(setvar "cmdecho" 0)
(setq css (ssget)) (command "copy" css "" "m")
(setq css nil) (setvar "cmdecho" 1)
(prin1) )
Enter CVV and press Enter to achieve multiple copies.

38. AUTOCAD2004 allows the use of objects such as lines, arcs, circles, ellipses or elliptical arcs, polylines, splines, construction lines, rays and text as shearing edges. The cutting edge can also serve as the cutting edge.
39. The chamfer distance is the length of each object that is trimmed or extended when it meets the chamfer line or intersects with other objects. If both chamfer distances are 0, the chamfer operation will trim or extend the two objects until they intersect, but will not create a chamfer line.
40. AUTOCAD allows you to add fillets to two parallel lines. As a result, AUTOCAD automatically sets the fillet radius to half the distance between the two parallel lines.
41. The layer set as the current layer must exist. When using the CLAYER command to set the current layer, the user must enter the layer name accurately, otherwise the setting will be invalid. This method of using the command line to enter the layer name is generally only suitable for experienced people, and beginners are not recommended to use it.

43. AutoCAD skills - automatically find boundaries when trimming or extending (extend)
When applying trim (trim) or extend (extend) commands, often Tip: Select the boundary first, then select the cut or extend object.
If you press Enter or right-click when prompted to select a boundary, you can directly select the object to be cut or extended. The boundary to be cut or extended is the entity closest to it.
It should be noted that if the entity is completely outside the current view, it will not be used as a boundary.
44. Drawing of polygons
AutoCAD can create equilateral polygons with sides from 3 to 1024. When drawing, you can choose the inscribed circle method or the circumscribed circle method. Generally, we use Directly enter the value of the side length or select the endpoint to complete. In fact, we can also draw by specifying the two endpoints of a certain edge of the polygon. This is especially suitable when part of the graphic has been drawn. This requires the use of the "Edge" parameter in the "Polygon" command. When After we click the "Polygon" button or enter the "Polygon" command, we first need to enter the number of sides of the polygon according to the prompts. Next, we need to select the "Edge" parameter, and then capture the two endpoints to complete the drawing of the polygon. This can greatly Save drawing time
45. How to remove the borders of pictures inserted with the IMAGE command:
Just set the system variable IMAGEFRame to OFF; if the ET tool is installed, directly Click TOGGLE FRame in the standard toolbar to remove the border, and click again to add a border.
To improve the drawing speed using AutoCAD software, skills are essential. Below are some tips that the author has summarized in practice. You might as well give it a try.
46. How to eliminate the education production drawing stamp in CAD:
1. Save the drawing file as an R12 DXF file and it should be eliminated
2. This print stamp cannot be removed using Autocad's own print stamp function. Otherwise, everyone can just spend the money of the educational version and enjoy the benefits of the commercial version. Copy the graphic to the commercial version and this stamp will remain.
I studied this problem a few months ago. The solution is very simple. Just open the file with DWG Express 6.0, convert it to any version (you can also not convert the format and version), and save it as other dwg file is OK.
3. Install DWGgateway v2.0.0.121 and convert the graphics to other versions, such as R14. There will be no "print stamp" when opening.
4. Change the ACPLTAMP.ARX file in the cad root directory to another name or delete it to eliminate the printing stamp
