DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a computer-aided drawing machine (CAD). More specifically, the present invention relates to a CAD apparatus particularly suitable for creating a circuit diagram.

[0002]

2. Description of the Related Art A conventional drawing apparatus basically includes a storage unit, an operation unit, a command processing unit, a drawing processing unit, and a display unit. The storage unit includes a primary storage device and a secondary storage device incorporated in the computer, and stores data representing a drawing to be processed. The operation unit includes a keyboard, a mouse, a digitizer, and the like connected to the main body of the computer, and sequentially inputs an event instructing a drawing operation of a drawing. The command processing unit includes software (program) executed by the CPU of the computer, and executes a command in response to an event input from the operation unit to perform a drawing operation of the drawing. The drawing processing unit also includes software and processes data according to a drawing operation. The display unit includes a CRT or LCD connected to a computer, and displays a drawing based on the processed data.

[0003]

There are many kinds of commands used in the drawing operation by CAD programs in advance. For example, there is a straight line command for inputting a necessary line segment on the drawing. Commands are executed according to the initial settings. For example, in the case of a straight line command, the line type of the line segment is set in advance. The line type refers to a line segment type such as a solid line, a broken line, a one-dot chain line, and a two-dot chain line. You may want to change the line type during the drawing operation. In this case, it has conventionally been necessary to end the line command once and start the line type setting command. After changing the line type by executing the setting command, the line command is started again to perform the drawing operation. In order to change the setting, it is necessary to switch the command one by one, which has been a problem to be solved in order to improve operability.

In a conventional CAD apparatus, for example, a command for performing a drawing operation on an individual object (such as a symbol of a circuit component) included in a circuit drawing and a command for checking the individual object are prepared. By creating and checking the objects, the design errors of the circuit drawings are prevented. However, conventional CAD
The device can basically execute only one type of command, and cannot simultaneously start a command for drawing and a command for checking. Therefore, when checking individual objects, it is necessary to switch between a drawing command and a checking command one by one, and to start them, which has been a problem to be solved in order to improve operability.

[0005] In the drawing process, there are cases where it is desired to correct or edit the previously drawn object. At this time, first, an event is input from the operation unit to select a target object. Next, a command required for modifying or editing the object is selected and activated. The user must select the required command for each object, and must input an event each time. In general, despite the limited number of commands for correction or editing used depending on the type of object, it is necessary to select each time from the menu, which is a problem to be solved in order to improve operability. Was.

And returning to the normal command in response to the fourth event input from the operation unit, and continuing the normal command according to the changed setting. For example, the command processing unit activates a normal command for drawing a line as a normal drawing operation in response to a first event input from the operation unit, and responds to a second event input from the operation unit. An interrupt command for setting the type of line is started without ending the normal command. Alternatively, the command processing unit activates a normal command for allocating characters as a normal drawing operation in response to the first event input from the operation unit, and responds to the second event input from the operation unit. Accordingly, an interrupt command for setting the font size of the character without ending the normal command is started.

According to a second aspect of the present invention, a drawing device basically includes a storage unit, an operation unit, a command processing unit, a drawing processing unit, and a display unit.

Inspect and modify objects. Preferably, the command processing unit executes the independent command in response to a first event input from the operation unit, causes the specified object to be displayed on the display unit in a selected state, and is input from the operation unit. The normal command is executed in response to the second event to correct an error in the selected object. More preferably, the command processing unit executes the independent command in response to a first event input from the operation unit, and automatically arranges a specified object in a selected state at substantially the center of the display unit. . The command processing unit, for example, checks a normal command for assigning a component identification symbol as a normal drawing operation to an individual object representing a component and an error in the identification symbol assigned to each object based on the manner of operation. Independent commands are operated in parallel with each other, and errors in the identification symbols of the individual objects specified by the execution of the independent command are corrected one by one by executing the normal command.

[0008] According to a third aspect of the present invention, the drawing apparatus basically includes a storage unit, an operation unit, a command processing unit, a drawing processing unit, and a display unit. The storage unit stores data representing individual objects included in the drawing to be processed. The operation unit sequentially inputs an event instructing a drawing operation of the object. The command processing unit executes a predetermined command according to the event to perform a drawing operation of the object. The drawing processing unit processes the data according to the drawing operation. The display unit displays a drawing including individual objects based on the processed data. As a characteristic feature, the command processing unit selects an object to be subjected to a drawing operation in accordance with a first event input from the operation unit, and inputs the object to the selected object from the operation unit. In response to the second event, a specific command related to the drawing operation of the object is automatically recognized and activated in advance, and the automatically recognized command is executed in response to the third event input from the operation unit. Image operation of the object. For example, the command processing unit selects a line segment as an object to be subjected to a drawing operation in accordance with a first event input from the operation unit, and inputs a line segment to the selected object from the operation unit. In response to the second event, a command for setting the line type of the line segment as a specific command related to the drawing operation of the object is automatically recognized and activated. Alternatively, the command processing unit selects a symbol of a component included in a circuit diagram as an object to be subjected to a drawing operation in accordance with a first event input from the operation unit, and selects a symbol for the selected symbol. In response to a second event input from the operation unit, a command for inputting an attribute of a corresponding component as a specific command related to the drawing operation of the symbol is automatically recognized and activated. Alternatively, the command processing unit selects a bus wiring symbol included in a circuit component as an object to be subjected to a drawing operation in accordance with a first event input from the operation unit, and selects a symbol for the selected symbol. Then, in response to the second event input from the operation unit, a command for inputting the name of the corresponding bus wiring as a specific command related to the drawing operation of the symbol is automatically recognized and activated.
Alternatively, the command processing unit selects a connection symbol included in the circuit diagram as an object to be subjected to a drawing operation in accordance with the first event input from the operation unit, and selects a connection symbol for the selected symbol. In response to the second event input from the operation unit, a command for deleting, extending, adding, branching, changing, or modifying the connection is automatically recognized and activated as a specific command related to the drawing operation of the symbol in advance. I do. Alternatively, the command processing unit simultaneously selects a plurality of objects to be subjected to a drawing operation in response to a first event input from the operation unit, and inputs the selected object from the operation unit. In response to the second event, the movement command is automatically recognized and activated as a specific command related to the drawing operation of the object in advance, and the movement command is automatically recognized in response to the third event input from the operation unit. A plurality of the selected objects are simultaneously moved by executing a movement command.

In the drawing apparatus according to the first aspect of the present invention, during execution of a normal command for a drawing operation, an interrupt command can be activated without terminating the command. The interrupt command can change the initial setting of the normal command. After executing the interrupt command to change the initial setting, the normal command can be returned again. The next drawing operation can be performed with the changed setting contents reflected. In order to realize such an operation, the normal command and the interrupt command are operated in different memory areas. By generating an initial setting reload event for the normal command at the end of the interrupt command, the initial setting can be changed,
You can continue the normal command with the changed contents. The initial settings can be changed at any time during execution of the normal command, and data having different attributes can be input without terminating the normal command.

[0010] In the drawing apparatus according to the second aspect of the present invention, an independent command which operates independently of the normal command used for the drawing operation is provided. Independent commands usually do not end when the command is run. The independent command continues running until it terminates itself or the program terminates. Inspection (check)

You can edit drawings. In order to realize such an operation, the memory used by the independent command is secured as a dedicated memory area, and the independent command operates independently.
The dialog of the independent command is always displayed on the screen of the display unit. When this dialog is activated and the check item in the list box is selected,
Control returns from the normal command to the independent command, and the independent command can be executed. When a drawing includes a plurality of objects, the error check and its correction are repeated for each individual object. In the present invention, a dialog is always displayed on a screen by making an error check command independent. The transition (jump) to the next object is simplified, the operability is improved, and the drawing efficiency is improved.

In the drawing apparatus according to the third aspect of the present invention, only one default command that is automatically recognized according to the object to be edited is allocated. The default command can be started by a simple event operation such as double-click. By assigning frequently used commands as default commands (automatic recognition commands) for each object, operability is improved and work efficiency is improved. For example, an attribute input command and an edit command of an object can be defaulted.

FIG. 2 is a flowchart showing a command control process executed by the command processing unit 15.
This command control processing relates to the first aspect of the present invention. As shown, in this embodiment, a straight line command is executed as a normal command (S1). The straight line command inputs a straight line at a desired position on the drawing by inputting a start point (S2) and an end point (S3) on the screen. A line type setting command can be activated as an interrupt command during execution of the straight line command (S4). The line type of the input straight line can be changed by executing the line type setting command (S5). After the line type is changed, the interrupt command is terminated, the command is returned to the normal command, and straight line input is performed again with the changed line type. In other words, the line type setting command (interrupt command) can be executed without terminating the straight line input command (normal command). When the line type is changed and the interrupt command ends, control returns to linear input again.

The command control process shown in FIG. 2 will be specifically described with reference to FIGS. FIG. 3 shows a screen during linear input. A window 51 for drawing operation is displayed on the screen. Drawing area 52 of window 51
Shows a part of the drawing to be processed. At the top of the window 51, a menu bar 53 is displayed. The menu bar 53 includes menu items such as file, edit, input, selection, display, window, tool, option, and help. When a desired menu item is selected, a pull-down list opens, and a list of commands included in the item is displayed. A desired command is selected from the command list and executed. For reference, FIG.
FIG. 33 shows a list of commands used in the plotter. This list includes normal commands, interrupt commands, and independent commands. Some of these commands can be set as automatic recognition commands. Returning to FIG. 3 again, a toolbar 54 is displayed below the menu bar 53. By clicking an icon included in the toolbar 54, a desired command can be activated.

FIG. 3 shows a state where a straight line is being input by executing a normal command. The first straight line L1 is input by designating the start point SP and the end point EP on the drawing area 52. Subsequently, the second straight line L2 is being input.

FIG. 4 shows a state in which the interrupt command is activated during the input of the second straight line. Here, a line type setting command is activated as an interrupt command, and a line type setting window 55 is open in addition to the window 51 indicating the drawing area. The window 55 is in an active state, a desired line type is selected, and an OK button is pressed. Here, a dotted line is selected as the line type.

FIG. 5 shows a state in which the line type setting command has been completed and has returned to the straight line input command. The window 55 corresponding to the line type setting command has already been closed. The second straight line L2 is input on the drawing area of the window 51. The line type setting has been changed from a solid line to a dotted line by executing the previous line type setting command. Therefore, the straight line L
2 is entered by a dotted line.

FIG. 6 shows another example of a combination of a normal command and an interrupt command. In this embodiment, a comment character input command is executed as a normal command. Executing this command opens a character input window 56 in addition to the main window 51. By inputting a comment character on the character input window 56 using a keyboard or the like, the first comment character C1 is input to the main window 51. Next, in order to change the character style of the input comment character, a character style setting command is started as an interrupt command. As a result, the character style setting window 57 opens and becomes active, and the character input window 56 changes to an inactive state. The scale (font size) of the character is changed using the window 57 for setting the character style. Thereafter, the character style setting command ends, and the process returns to the character input command to activate the window 56 again.
When comment characters are entered in this state, the main window 5
1, the second comment character C2 is input in the changed font size. As described above, when changing the character style, the character style setting command can be activated by interruption without terminating the character input command, and the operability is improved.

FIG. 7 shows the command processing unit 15 shown in FIG.
5 is a flowchart showing a command control process executed by the first embodiment, and particularly shows a command control process related to the second aspect of the present invention. Here, a command for allocating an identification number (component ID) of a component included in the circuit diagram as a normal command is executed (S11). By inputting the component ID via the keyboard, the component ID can be assigned to the vicinity of the selected component symbol (S12). On the other hand, in parallel with the allocation command, which is a normal command, the part ID non-check command is executed as an independent command here (S13). When this independent command is executed, a symbol having an error in the component ID is displayed (S14). Part I
By operating the allocation command (normal command) without ending the D no-check command (independent command), errors can be corrected for a plurality of component symbols without repeatedly ending / starting the component ID no-check command. become.

FIGS. 8 to 11 specifically show the command control processing shown in FIG. First, as shown in FIG. 8, a circuit diagram to be processed is displayed in a drawing area 52 of a main window 51. This circuit diagram includes a plurality of component symbols LS161, LS04, LS374, L
S32 and LS04 are included in order from left to right. In this state, the component ID no check command is activated by sequentially tracing the pull-down list from the tool item of the menu bar 53. The various check commands shown in the pull-down list are generally independent commands.

As shown in FIG. 9, by executing the component ID no check command, a sub window 58 for component ID no check is opened in addition to the main window 51.
In the sub-window 58, symbols to which no component ID is assigned are listed as component names LS04, LS32, and LS374. For example, the part name LS04 is selected in the part ID no check window 58. As a result, a symbol having the part name LS04 is displayed in a selected state substantially at the center of the drawing area 52 of the main window 51.

Subsequently, as shown in FIG. 10, a component ID input command is activated as a normal command. As a result, a sub window 59 for inputting a component ID is opened on the screen in addition to the main window 51 and the window 58 for checking no component ID. In this case, the normal command is activated in parallel with the independent command. The part ID no-check window 58 is deactivated, and the part ID input sub-window 59 is activated.
The part ID to be assigned is input to S04. As a result,
A part LS displayed in a selected state substantially at the center of the drawing area 52
The input component ID is assigned near the symbol 04.

As shown in FIG. 11, the sub window 59 for inputting the component ID is closed once, and the process returns to the component ID non-check command. The next part name LS32 is selected from the list displayed in the sub window 58 again. As a result, in the drawing area 52, the symbol of the component LS32 is displayed substantially at the center in a selected state. The symbol of the component LS04 for which the input of the component ID has been completed has moved to the lower right of the drawing area 52. By executing the component ID input command again, a predetermined component ID is given to the symbol of the component LS 32 displayed in a selected state substantially at the center of the main window 51 in accordance with the design specification of the circuit diagram.

FIG. 12 shows the command processing unit 15 shown in FIG.
5 is a flowchart showing an overall flow of a command control process executed by the server. The command control process is executed in response to an event input from an operation unit such as the keyboard 3 and the digitizer 4 shown in FIG. First, in step S21, a button event input from the operation unit is determined. The button event is input by pressing a pair of left and right buttons incorporated in the stylus of the digitizer. Alternatively, a button event can be input by clicking the left and right buttons provided on the mouse. When the left button is clicked, the selection command is executed in S22.
If the right button has been clicked, the process proceeds to step S23, and it is determined whether the activation of the independent command has been requested. In the case of YES, an independent command is executed in step S24. In the case of NO, the process proceeds to step S25, and it is determined whether or not activation of the interrupt command is requested. YES
In this case, the process proceeds to step S26, where it is determined whether an interrupt command is already being executed. In the case of YES, the process proceeds to step S27 to cancel the interrupt command that is being executed first. Thereafter, the process proceeds to step S28 to execute a new interrupt command. If NO is determined in the step S26, the process directly proceeds to a step S28 to execute the interrupt command. If NO is determined in the step S25, the process proceeds to a step S29 to determine whether or not the activation of the normal command is requested. If YES, step S3
The process proceeds to 0, and it is determined whether or not the normal command is already being executed. In the case of YES, the process proceeds to step S31 to cancel the previous normal command. After this, step S3
Proceed to 2 to execute a new normal command. Step S3
When the determination is 0 and NO, the process directly proceeds to step S32. If NO is determined in the step S29, the present command control process ends.

FIG. 13A is a flowchart showing details of the selection command execution step S22 shown in FIG. First, in step S221, it is determined whether or not the object targeted for the selection command has already been selected. If the object is not in the selected state, the process proceeds to step S222 to perform a process of selecting the object. If the button event has already been selected, the process proceeds to step S223 to determine the type of the button event. If the button event is a double click, a double click process is performed in step S224. If the button event is a drag, a drag process is performed in step S225. If the type of button event is click, a click process is performed in step S226.
