You can run the common commands entered inside

2.Describes how the command is entered, and describes the characteristics of the process in which the command runs.

A: The input command CPU is mainly composed of combinators, controllers, register banks and internal buses, we know that combinators are used to complete operations, and the execution of instructions is done in the controller. The controller generally includes command control logic, timing control logic, bus control logic and interrupt control logic.

To be more precise, the execution of instructions is completed by instruction control logic, so let's take a look at the composition of instruction control logic.

1: Enter the command in the command line window:

When you input a command from CAD2014, the letters are not divided into uppercase and lowercase, as long as the command line you input is correct, you can successfully enter the operation window of the command.

2: Enter the abbreviated letters of the command in the command line window:

CAD 2014 abbreviation line designers often refer to CAD shortcuts, that is, commands to quickly enter CAD commands. For example: l (line), c (circle), a (arc), etc., this command input method is one of the most used methods by front-line workers.

3: Use the drawing toolbar:

The outside of the CAD2014 drawing window provides users with a variety of toolbars for general drawing, through which the user does not need to enter commands manually, just find the required command and click on the drawing toolbar.

4: Use the menu bar drop-down tool.

In CAD2014, the second line at the top is the menu bar, in the drop-down menu of each menu bar, there are different drawing commands, through the drop-down menu of the menu bar can also quickly enter the drawing, in fact, all the commands of CAD software, can be found in the menu bar.

5: Key combination.

For example, CAD save, open, new and other commands, you can use ctrl+s, ctrl+o, ctrl+n and other forms of key combinations, there are many such key combinations, users can find and record in CAD2014 for the next use.

6: Right-click in the drawing area.

Right-click in the CAD2014 drawing window, you can pop up a shortcut menu bar, but there are not many commands in this shortcut menu bar, basically some operations are relatively high will appear in this toolbar, most of the commands also need to use the first 5 methods.

Learning morality: Although there are many ways to operate AutoCAD2014, the commonly used ones are nothing more than the use of shortcut commands, key combinations, toolbars, etc., the entry methods of these commands do not require users to remember, as long as they are in line with user habits, one or two can be.
