DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a technique for assisting drawing by using a computer, and more particularly, to a technique for performing routine work at high speed.

[0002]

2. Description of the Related Art A CAD (Computer Aided Design) system is a system for supporting drawing by using a computer, and is applied to various fields such as mechanical, architectural, electric and civil engineering design and form creation. In such a CAD system, the user inputs the type, position, angle, size, and the like of various figures, such as straight lines, rectangles, arcs, and characters, arranged on a drawing while checking them on a computer display screen. By going, a drawing can be created. When creating another drawing based on one drawing, it is possible to create a new drawing in another area while displaying the original drawing in one area of the display screen and referring to it. is there.

[0003]

By the way, in the drawing operation, a fixed type and number of new figures are added according to a certain regularity based on the already arranged figures. There are many. However, in the conventional CAD system, since it is necessary for the user to individually and specifically specify the position and size of each graphic,
Efficient drawing was difficult.

[0004] For example, a case will be considered in which, based on an architectural plan view as shown in FIG. In order to create a material summary table, it is necessary to create an electrical appliance wiring diagram beforehand. To create such a wiring diagram, the designer who is the user, while reading the size and shape of the building from the plan view, decides where and how to place all the electrical appliances on their own. After judging, it was necessary to repeat the work of manually arranging the electric equipment on the drawing.

In particular, when arranging instruments on a drawing, as shown in FIG. 5, a position is designated by a manual designation frame 10 controlled by a mouse or the like, and an operation such as clicking a mouse button is performed. It is necessary to perform an operation such as disposing the lamp 11 for each appliance. In the wiring diagram, it is necessary to determine not only the arrangement of the individual appliances but also the interconnection between the appliances while calculating the voltage drop or the like by oneself.

Further, in order to create a material summary table as shown in FIG. 6 from the wiring diagram created in this way, the number is counted one by one for each type of electric appliance while referring to the completed wiring diagram. Then, it was necessary to repeat the work of writing necessary items such as items and quantities in the material summary table.

Thus, in the conventional CAD system,
Even during routine work, the user had to specifically specify the arrangement and the like for each figure, making efficient drawing difficult. It is to be noted that a conventional technique for performing a continuous process on a plurality of graphics is also known. However, this kind of conventional technique merely stores some simple operations and mechanically repeats them. It was not possible to perform routine tasks such as the arrangement of the drawings according to the rules of drawing.

The computer that can be used to implement the present embodiment may have a general hardware configuration, and more specifically, a CPU.
(Central processing unit), and a main storage device including a RAM (continuous write-once storage element). The size of the computer is arbitrary, and any computer such as a personal computer and a workstation may be used. The computer typically includes an input device such as a keyboard and a mouse, an external storage device such as a hard disk device, an output device such as a CRT display device and a printer, and other necessary input / output control circuits. Having.

[1-1-1. Hardware] However, the configuration of the computer is free, and some of the above-described components may be added, changed, or excluded as long as the content of the present invention is not violated. Further, a single CPU may be used for time sharing (time sharing), a plurality of processes may be performed simultaneously in parallel, or a computer constituting a network may be used. Further, in the computer, as an input device, another device, for example, a pointing device such as a touch panel, a light pen, a trackball, a digitizer,
An image reading device, an image input device such as a video camera, a voice identification device, and various sensors may be used.

In the computer, another device such as a liquid crystal display device, a plasma display device, a video projector, an LED display device, a sound generation circuit, and a speech synthesis circuit may be used as the output device. Also,
When a printer printing device is used as the output device, the type is also free. For example, a laser beam printer, an ink jet printer, a dot matrix printer, a plotter printer, a line printer, a thermal transfer printer, a discharge printer, an electric typewriter, and the like can be freely used. Can be used.

[1-1-2. Software] Also, as a configuration of the software of the computer, typically, a mode in which a program for realizing each function of the present apparatus is executed as an application program on an OS (Operating System) is considered. Can be However, the configuration of the software of the computer can be freely changed. For example, it is not always necessary to use an OS, and each function of the apparatus may be realized by a microprogram of a CPU. In addition, the expression form of the program is also free. Typically, a machine language compiled (translated) from a high-level language or an assembler is considered, but using an interprinter (sequential interpretation execution type) language such as BASIC. Is also good.

Each means is a conceptual one corresponding to each function of the present apparatus, and does not necessarily mean mutually independent hardware. For example, one input unit and another input unit may be realized on the same keyboard, and similarly, one output unit and another output unit may be realized on the same image display device. Further, one means may be realized by only one instruction, or may be realized by many instructions.

The program may be stored in any form. The program may be stored in a ROM (read only memory), or may be stored in an external storage device such as a hard disk device. At the start of the processing, it may be mainly loaded (read) on the memory. Also,
The program may be divided into a plurality of parts and stored in the external storage device, and only necessary modules may be loaded (read) into the main memory at any time according to the processing content. Further, the program may be stored in a different manner for each part of the program.

[1-1-3. Input and output] In addition, "input" in the present application means not only input of original information,
Includes other processes closely related to the input of information. Such processing is, for example, echo back (output for confirmation) of the input content to the output device, and correction / editing of the input content. Further, “output” in the present application includes not only output of the original information but also other processes closely related to the output of the information. Such processing is, for example, an input for limiting an output range or an instruction to scroll information on a display screen. The input means and the output means may be realized as an integral part by an interactive interface method. Similarly, such integration of input and output can be applied to processing based on some output information, such as “select” or “identify”.

[1-1-4. Storage means] The storage means referred to in the present application is sufficient as long as it can hold constant information for a fixed time, and the mode of implementation is free. Therefore, the storage means does not mean only a specific storage mode such as an external storage device or a file format. Also,
The storage means is typically realized as a predetermined area on the main storage device, but may be realized not only on the main storage device but also on an external storage device. May be used.

When there are a plurality of storage means, the storage devices for realizing each storage means may be of the same type or different types. Further, the storage means may be in any format, and may be realized by directly accessing the main memory or the external storage device by using an address or a physical recording position without using a file format. Also,
It is sufficient for the storage means to be temporarily present when necessary, and may then disappear. Information that is not changed for the time being, such as a dictionary, may be stored in the ROM.

Further, each storage means does not need to be dedicated for the purpose of the present invention, and may also serve simply as a part for stored data. Further, the content and format of the information are free. For example, the character string may be stored in a code in a character unit or a code in a word unit. Further, information stored in other storage units may be copied and used in each storage unit. Further, the description of the storage means is for confirming the existence of the information, and does not deny the existence of the information which is not specified regarding the storage means. Therefore, the present apparatus can provide other information necessary for the operation of the present apparatus (for example, various pointers, counters, flags, parameters, buffers,
Others) are appropriately used.

[1-1-5. Processing Procedures and Others] In addition, the steps of each procedure in the present embodiment may be executed in a different order, and may be executed simultaneously, or may be executed in a different order for each execution, as long as the nature of the steps is not violated. Such a change in the order can be performed by a menu-type interface method, for example, by selecting a process that can be performed by the user.

Unless otherwise specified, the information required by each part of the apparatus for processing is obtained from other parts that hold the information based on processing such as input, generation, and storage. Such acquisition of information can be realized by, for example, accessing a variable or memory storing the information. Note that the erasure / deletion of information can be performed by changing the meaning of information, such as setting a flag indicating erasure, without actually deleting the content itself from the storage area. Further, although the present device is realized on a computer, all or a part of the functions of the present device may be realized on a dedicated electronic circuit.

[1-2. Definition of Terms] Next, definitions of terms in the present application will be described. First, a "drawing" is the content of a document in which one or more figures are arranged on a certain area. "Figure" is an individual element that is a unit arranged on the drawing. Not only original geometric figures, but also characters, masking frames, dimension lines, various symbols, patterns of background patterns, etc. , Is a broad concept that includes all types of elements that make up the drawings. Further, the “graphic” includes a graphic defined by combining and integrating a plurality of graphics.

"Graphic information" is information representing individual figures, and is specific enough to enable automatic arrangement. The contents of such graphic information include, for example, numbers, types, shapes, dimensions on drawings, coordinate values, arrangement angles, color information, layer information, and the like for each graphic. The information representing one drawing is a combination of the graphic information of each figure included in the drawing and information such as the name, size, scale, and printing format of the whole drawing. In addition,
Information such as the name, dimensions, scale, and printing format of the entire drawing may be stored as a type of graphic information or may be stored separately from graphic information.

In this embodiment, graphic information is processed according to rules. Graphic information that can be processed is called "old graphic information", and a graphic represented by the old graphic information is called "old graphic". Call. The graphic information created by the processing according to the rule is called “new graphic information”, and the graphic represented by the new graphic information is called “new graphic information”.
Call.

[1-3. Configuration Based on Functional Block Diagram] The functional block diagram of FIG. 2 shows the configuration of the present apparatus implemented on the computer based on the above definition of terms. Each function of the present apparatus is realized by operating the above-described computer according to a predetermined procedure stored as a program. Therefore, the present device will be described below assuming a virtual circuit block (means) having each function of the present device.

First, as shown in FIG. 2, the present apparatus has a rule storing means 1 (corresponding to "first storing means" in claim 1) for storing rules in advance. This rule is for creating graphic information of a new graphic by processing graphic information representing the graphic.

Further, the present apparatus has a basic information storage means 8 (corresponding to the "second storage means" in claim 1) for storing basic information in advance. Here, the “basic information” is basic information of the graphic information of a new graphic created by the processing based on the rule, and is, for example, information representing the shape of the new graphic. The apparatus also has an input means 2 for inputting graphic information and a graphic information storage means 3 for storing graphic information.

Further, the present apparatus has processing means 4 for generating graphic information of a new graphic by processing graphic information based on the rule and the basic information. Here, “processing” is a concept including not only adding or changing graphic information, but also counting and calculating numerical values based on old graphic information to be processed. For this reason, the processing means 4 also has a function of calculating a numerical value. Also,
The "graphic information of a new graphic" created by the processing includes graphic information created by changing the old graphic information as well as graphic information added completely separately from the old graphic information.

Further, the present apparatus includes an old graphic storage means 7 for storing old graphic information, a drawing means 5 for drawing a graphic for output based on the graphic information, and an output means 6 for outputting the drawn graphic. Having. The apparatus also has a designating unit 9 for designating, from each of the old graphic information, a target to be processed by the processing unit 4.

[2. Operation and Effect of Embodiment] The present embodiment having the above configuration has the following operation. [2-1. Preparation of Rules and Basic Information] First, prior to drawing, a rule for processing graphic information is created in advance and stored in the rule storage means 1. As a rule format, for example, a first part that defines what graphic information is to be processed and a second part that defines what processing is to be performed on such an object are described. Is considered. In addition, as the contents of the processing for the graphic information of a certain kind of figure, another certain figure is added near the figure, or the number of such added figures is counted and entered in another table. For example, a process for realizing the above can be considered. In addition, the contents of the processing include condition judgment, repetition,
Specific numerical values can also be included. Specific examples of the rules will be described later.

Also, basic information relating to a new figure created in the processing is created in advance and stored in the basic information storage means 8. The contents of such basic information include, for example, if the rule is to add graphic information of a graphic different from the old graphic as new graphic information, a bitmap or diagram data representing the shape of the graphic is added. Can be considered. If the rule is to count figures represented by the old figure information and enter them in another table, data representing the format of the table can be considered.

[2-2. Input of Graphic] Next, the drawing procedure in this embodiment is shown in the flowchart of FIG. In this procedure, first, the user inputs graphic information representing a graphic from the input means 2 (step 31). Prior to inputting the graphic information, input the size, scale, name, etc. of the drawing in which the individual graphic information is to be arranged, and then input the individual graphic information to be arranged on the drawing. repeat. To enter individual graphic information, like a conventional CAD system or graphic editor,
On the display screen, the type of the figure to be used is selected, and the display of the figure is moved, deformed, and rotated with, for example, a mouse cursor to arrange the figure at a desired position, size, and angle. When the graphic is arranged on the screen in this way, graphic information is created for the graphic in a representation format inside the computer and stored in the graphic information storage means 3 as old graphic information that can be processed (FIG. 2). ).

Further, graphic information created in the past and stored on a hard disk or floppy disk may be read and used, or a file may be taken out from another computer connected to the same network and used.

[2-3. Processing on Graphic Information] Subsequently, processing based on rules is performed on the old graphic information input as described above. The processing based on a certain rule can be performed for all the objects defined by the rule, or can be performed by designating a part of them. In other words, when performing a process by designating a part of the processing targets defined by the rule, the user specifies the graphic information to be processed by the specifying unit 9. This designation can be made, for example, by depressing a mouse button while pointing a desired graphic on a display screen using a mouse cursor. When a graphic is designated in this way, a flag indicating that the graphic information corresponding to the designated graphic may be processed is set.

Then, in order to start the processing based on the rule, the user instructs the processing by performing a predetermined operation. This command is input by, for example, selecting a predetermined item from a menu bar, pressing some keys in a predetermined combination, or typing a predetermined command from a keyboard. When a plurality of rules are stored in the rule storage unit 1, a rule to be used is selected from a list displayed on the screen.

When the processing based on the rule is instructed as described above, the processing means 4 first selects the old graphic information stored in the graphic information storage means 3 into a processing target defined by the rule. The matching old graphic information is detected (step 32). This detection can be performed by comparing each old graphic information stored in the graphic information storage means 3 with the processing target condition defined in the first part of the rule. At this time, if graphic information that may be processed is specified by the specifying means 9,
Of the old graphic information that satisfies the condition defined by the rule, only the graphic information for which the flag indicating that processing is possible is set is detected as the processing target.

When the detection of the processing target is completed, the processing means 4 stores each detected old graphic information in the old graphic storage means 7 prior to the processing (step 33). The storage of each detected old graphic information in this manner is performed by temporarily deleting the graphic corresponding to the old graphic information to be processed from the screen display, thereby creating a space on the screen for drawing the new graphic again. On the other hand, if the processing result is different from the desired result, the user can cancel the processing and return the drawing to the state before the processing.

When the old graphic information is stored in this manner, the processing means 4 deletes each graphic corresponding to each detected old graphic information from the drawing display VRAM or the buffer memory for printer output, and then executes the processing. Processing based on rules is performed on the old graphic information detected as a target (step 34). The content of the processing is defined by a rule, and the processing means 4 reads out the basic information from the basic information storage means 8 and uses it when creating graphic information of a new graphic by processing based on the rule. For example, when a figure different from the old figure is added as a new figure based on a rule, the shape of the new figure is read from the basic information storage unit 8. When counting the number of old figures and writing the number in another table, the format of the table is read from the basic information storage means 8.

The processing means 4 determines information other than such basic information, for example, details of the position, attribute, dimensions, and the like at which the new graphic is arranged, based on the old graphic information and rules. For example, when a new graphic is arranged at a certain distance from an old graphic, the distance between the two is added to the reference point of the coordinate position of the old graphic to calculate the reference point of the coordinate position of the new graphic. When a new table or the like is created as a new graphic, the graphic information of the table may be added to a part of the drawing including the graphic information to be processed or may be saved as another new drawing. Good.

If the new graphic information created by the processing is created by changing the old graphic information, the new graphic information is replaced with the old graphic information in the graphic information storage means 3. If it is added separately from the information, it is newly added to the graphic information storage means 3.

When processing a plurality of graphic information,
The above-described processing for each graphic information is collectively and continuously performed, and drawing of each graphic is performed collectively after a series of processing is completed. Therefore, with respect to new graphic information changed or added by a certain process, drawing is not performed immediately, but a predetermined undrawn flag indicating that drawing is not performed is set instead.

[2-4. Drawing and Output] When the above-described processing is completed for all the old graphic information detected as the processing target, the drawing means 5 outputs based on each graphic information stored in the graphic information storage means 3. Is drawn (step 35). In this drawing, the drawing display VR
It is sufficient to write a bitmap image of a necessary graphic in an AM or a buffer memory for printer output. If a plurality of pieces of graphic information are processed, drawing is performed for each piece of graphic information for which the undrawn flag is set, and the undrawn flag is reset for the drawn graphic information. Then, the figures drawn in a lump as described above are output from the output unit 6. (Step 36).

[2-5. Specific Example] Next, a specific example of drawing according to the present embodiment will be described. For example, it is assumed that the plan view shown in FIG. 4 is created and given as a drawing of the type “building outline drawing”. This plan view is a combination of figures such as a wall, a window, and a character string “Western room”. And
From this plan view, the material total table 1 of the electric appliance shown in FIG.
Consider a case where 8 is created as a new figure. In this case, prior to the creation of the material tabulation table, by arranging electrical members on the plan view of FIG. 4, a wiring diagram as shown in FIG. 5 is virtually created on the work area. Count the number of devices in the figure, and use the number to
Will be created.

Here, Rule 1 for virtually creating a wiring diagram from a building outline drawing is as follows: [Rule 1] Type of drawing to be processed: Building outline drawing Figure to be processed: Wall Processing contents : It is assumed that there is a rule that one outlet is arranged on each wall, and the shape of the symbol mark is stored as basic information of the outlet. in this case,
The processing means 4 detects the graphic information of the wall as a processing target from the graphic information of each graphic constituting the architectural outline drawing, so that one outlet is arranged for each wall.
Create new graphic information representing each outlet. As a result,
For example, when there is a kitchen 12 as shown in FIG. 7 as a part of the architectural outline drawing, a wiring diagram in a state where a total of four outlets 13 are arranged for each wall of the kitchen 12 as shown in FIG. Created.

Further, as rule 2 for arranging electric appliances other than the outlet, [rule 2] type of drawing to be processed: architectural outline drawing target to be processed: wall constituting a room There is a rule that wiring is performed by arranging only one joint box, one light and one switch in one room, and the shape of a symbol mark representing each is stored as basic information of the joint box, one light and one switch. It is assumed that the shape of the broken line representing the wiring is stored as the basic information. In this case, the processing means 4 detects the walls constituting the room by judging from the old graphic information of the individual walls how the adjacent old graphic walls are adjacent to each other. Then, a process of arranging and wiring one joint box, one light and one switch per room is performed. In this process,
New figure information representing a new figure, such as a joint box, lighting, a switch, and a wiring is created. As a result, for example, as shown in FIG. 9, a wiring diagram in which the joint box 14, the lighting 15, and the switch 16 are arranged and the wiring 17 is added is virtually created in the area of the kitchen 12.

Further, as Rule 3 for creating a material summary table from the wiring diagram virtually created as described above, [Rule 3] Process target: Virtually arranged electric appliance Processing contents: Each appliance It is assumed that there is a rule that the number is counted and transferred to the material summary table, and the display format of the material summary table and the display item list are stored as basic information on the material summary table. In this case, as shown in FIG. 6, the processing means 4 first creates a material tabulation table having a unit column 18, an item column 19, a quantity column 20, and the like using the basic information. Further, the processing means 4 refers to the virtually created wiring diagram, counts the number of electric appliances, which are old graphics, arranged in the wiring diagram for each type, and counts the number in the quantity column of the material tabulation table. By transferring the data to 20, the material summary table shown in FIG. 6 is completed. In this process, each electric appliance arranged in the wiring diagram is an old figure, and the material tabulation table is a new figure.

[2-6. Effect of Embodiment] As described above, according to the present embodiment, the contents of the routine work are stored in advance as rules, and the input graphic information can be automatically processed based on the rules. Is speeded up and drawing is performed efficiently. Further, even a person other than a design technician can easily draw a drawing, and erroneous drawing can be easily prevented as compared with a case where all drawing is manually performed.

In this embodiment, the user can specify graphic information that can be processed according to specific circumstances such as the purpose of the processing. For this reason, a portion that does not require processing can be excluded from the target, and the processing time can be reduced.

When redrawing a figure based on certain figure information, it takes a certain amount of time to erase the periphery of the figure or the whole drawing once and then draw again. However, according to the present embodiment, When performing processing on a plurality of pieces of graphic information, drawing is performed collectively after performing the processing collectively. For this reason, it is sufficient to erase the drawing before processing once, and it is not necessary to repeat the erasing and drawing, so that the drawing is speeded up.

[3. Other Embodiments] The present invention is not limited to the above embodiments, but includes other embodiments as exemplified below. For example, it goes without saying that a character can be treated as a graphic. For example, a process of adding a name for each type of member can be realized as a rule. In addition, the contents of the processing defined by the rules can be freely determined, and complicated calculations, deletion of graphic information matching the conditions, and the like may be added to the processing contents.

In the specific example of the above embodiment,
In order to obtain the final purpose of the material summary table, figure information such as outlets was virtually created on the work area, but such figure information was not only created virtually but also actually output, It may be stored in graphic information storage means or the like. In this way, it is easy to check the progress of the process to the final purpose.

It is of course possible to manually edit, add, modify and delete new graphics created by the processing means 4 in the same manner as in the prior art. For example, it is possible to perform detailed drawing work, for example, the user introduces some exceptions to the principle represented by the rule.

Further, as in the case where some electric appliances have already been arranged in the architectural outline drawing, a rule may be added such that graphic information being processed is to be processed. As such a rule, for example, when an electric appliance is to be arranged, if an appliance of the same type has already been arranged at that position or a nearby position, a rule that skips the arrangement can be considered. By using such rules in combination, it is possible not only to apply the processing to the graphic information in the course of work without any problem, but also to make it possible to arrange the drawings in a complicated manner and to create more diverse drawings. Become.

In the above embodiment, the architectural outline drawing is taken as an example, but the rule storage means 1 and the basic information storage means 8
