CAD command three-key restore

What if the system variables in CAD are changed unintentionally, or some parameters are adjusted deliberately? At this time, there is no need to reinstall, and no need to change one by one. Solution:

OP option-----configuration-----reset

But after recovery, some options need some adjustments, such as the size of the cross cursor, etc.~

When pressing and dragging the button or wheel, panning operation is supported.

 

The model in the command line, the solution is missing

op----option------display----display layout and model tab (check it)

 

CAD skills

As we all know, there are two OK keys, one is "Enter" and the other is "Space", but now let's use the right button to replace them. Solution:

OP option-----User system configuration-----Use the shortcut menu (tick) to customize the right button in the drawing area

But before that, you have to create your own example table.

 

How to reduce file size

After the drawing is finished, execute the PURGE command to clean up redundant data, such as useless blocks, layers without entities, unused line types, fonts, size styles, etc., which can effectively reduce the file size. Generally, a thorough cleaning requires two to three times of PURGE.

 

-purge, add a minus sign in front, the cleaning will be more thorough.

 

Why the height of the input text cannot be changed

When the height value of the font used is not 0, the DTEXT command is used to write the text without prompting to enter the height, so the height of the written text is unchanged, including the dimensioning performed by the font.

Input of special symbols

We know that the "Ф" that represents the diameter uses the control code %%C, the "±" that represents the ground level uses the control code %%P, and the degree symbol "°" uses the control code %%D. But how to input it in CAD

1) T text command, drag out a text box

2) Right-click in the dialog box-symbol-some options will appear

 

What if the printed font is hollow

Enter the TEXTFILL command on the command line. If the value is 0, the font is hollow. A value of 1 means that the font is solid.

How to close *BAK file in CAD

1) Tools-Options, select the "Open and Save" tab, and then remove the check mark before "Create a backup every time you save" in the dialog box.

2) You can also use the command ISAVEBAK to modify the system variable of ISAVEBAK to 0. When the system variable is 1, a "*BAK" backup file will be created every time you save.

 

In CAD, the box showing the coordinates at the bottom left of the drawing area sometimes turns gray. What if the displayed coordinates do not change when the mouse moves in the drawing area

At this time, you need to press F6 or modify the COORDS system variable to 1 or 2.

 

When the system variable is 0, it means that the coordinate display is updated when the point is specified by the pointing device. 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 constantly updated. When the distance and angle are needed, the distance and angle to the previous point are displayed.

 

What if the content of layer 1 is obscured by the content of layer 2
