Type a command or system variable by using the keyboard. System variables are such parameters that are available for controlling how certain commands work.
Enter Commands on the Command Line
Type the full command name on the command line and press ENTER or SPACEBAR, or right-click your pointing device to start the command.
Some commands also have abbreviated names. Abbreviated command names are called command aliases. To define your own command aliases, you can customize from Aliases tab on the Customize dialog through performing CUSTOMIZE command.
Specify Command Options
Once you have entered commands on the command line, ZWCAD displays either a set of options or a dialog box. To choose a different option, enter the one of the options in the brackets, either uppercase or lowercase letters is OK.
To execute commands, press SPACEBAR or ENTER, or right-click your pointing device when the command names has been entered or responsive to prompts.
Repeat and Cancel Commands
If you want to repeat a command that you have just used, press ENTER or SPACEBAR.
To cancel a command in progress, press ESC.
To repeat the command you just used
Do one of the following:
Nesting a command
If you are working in the command bar, you can use another command from within a command, called nesting. To use a command inside an active command, type an apostrophe before you type the command, such as 'circle, 'line, or 'pyramid. You can nest commands indefinitely in ZWCAD. Many menu and toolbar macros work this way by default; for example, select color, reference grid, zoom, and snap. When you have finished with the nested command, the original command resumes.
For example, you turn on the object snap while you are drawing a circle, thus you can setup Object snap mode before continuing drawing.
2Point/3Point/Ttr(tan tan radius)/Arc/Multiple/<Center of circle>: 'osnap
( Setup object snap mode as Center in Draft Settings dialog, and then close the dialog to go on performing CIRCLE command )
2Point/3Point/Ttr(tan tan radius)/Arc/Multiple/<Center of circle>:
Enter System Variables on the Command Line
System variables are available for controlling how certain commands work. For example, GRIDMODE is used to control the status ON or OFF for "SNAP","GRID"or"ORTHO"mode, Sometimes you use a system variable in order to change a setting. System variable can be used to display the current status as well.
While using another command; you can examine or change a system variable's setting transparently, however, new values may not take effect until the interrupted command ends.
