The variables in AutoCAD

The variables in CAD (The system variables in AutoCAD): The system variable in AutoCAD is used to save the control parameters for commands. Sometimes we do not use commands well because system variable was changed (intention or carelessness). In this writing, we will introduce some popular system variables in CAD.

PICKFIRST: If this variable is 0, when you choose the object then type the command. It will require you choose the object again. The old object will be deselected.
PICKADD: If this variable is 0, you just can choose each object one by one. When you choose new object, the old object will be deselected.
PICKAUTO: If this variable is 0, you can not use crossing or window to choose the object automatically (You must type C or W when the prompt mark chooses)
PICKDRAG: If this variable is 1, when you choose crossing or window, you have to drag the mouse (similar to corel, word,…) instead of pick 2 times.

QTEXT: If this variable is on, your text will become a rectangle and display very quickly. Choose “on” for variable when there are lots of texts in drawing, but you do not have demand to see them.
MIRRTEXT: If this variable is 1, text will be reversed when using mirror command. If this variable is 0, text will be normal as in mirrtext command. This command also works with Attribute in block.
CURSORSIZE: Size of pointer, 100 is whole screen, 5 is original default when installing ACAD.
FILEDIA: If this variable is 0, all dialog boxes asking about file disappear. For example, when you use Open command, instead of familiar dialog box, ACAD will ask your file name at COMMAND.

Good luck!
