Description

Applied for application of Article 30, Paragraph 2 of the Patent Act Sold to Otsuka Shokai Co., Ltd. on April 20, 2021 Outline was released through telecommunication lines on April 23, 2021

The present invention relates to an information processing device, an information processing method, and an information processing program.

2. Description of the Related Art Devices for creating (including editing) drawings such as blueprints by generating objects of various shapes on a screen are widely used. For example, Patent Literature 1 describes a CAD/CAM system comprising a CAM system that creates NC machining data using shape data created by a CAD system. This system includes extraction means for extracting overlapping line segments from shape data created by a CAD system, replacement means for replacing the extracted multiple line segments with one line segment, and one line segment after replacement. dividing means for dividing the segment at intersections of the line segment with other non-overlapping line segments.

JP-A-05-020402

The system described in Patent Literature 1 replaces multiple overlapping line segments with a single line segment. For this reason, if the plurality of line segments are intentionally given different attributes, the attribute of one of the line segments may be replaced, causing inconvenience.

For example, a first line segment and a second line segment having relatively different thicknesses partially overlap each other, and each of the first line segment and the second line segment has a non-overlapping region that does not overlap each other. In some cases, the non-overlapping area of at least one of the first line segment and the second line segment must be changed by replacing it with a single line segment. Similarly, in the case of the first line segment of the solid line and the second line segment of the chain line, by replacing with one line segment, at least one of the first line segment and the second line segment The overlapping area has to be changed.

In order to maintain the attribute of the non-overlapping region in either the first line segment or the second line segment, it is necessary to divide one line segment after replacement at an appropriate dividing position and change the attribute again. In this case, specifying the division position is not easy, and operability is poor.

An object of the present invention is to provide an information processing apparatus, an information processing method, and an information processing program with good operability.

According to a first aspect of the present invention, when a line overlapping area is detected in a plurality of designated objects, some objects among the plurality of objects having the overlapping area are selected.
According to a second aspect of the present invention, when a line overlapping region is detected in a plurality of specified objects, the overlapping region in some of the plurality of objects having overlapping regions is divided into non-overlapping regions. Make it selected.

According to the present invention, the operator can grasp the overlapping area in advance and predict the processing result. Therefore, a necessary operation can be performed based on the predicted processing result, and the overlapping area can be processed without unnecessary operations.

FIG. 4 is an explanatory diagram of information stored in a storage unit; FIG. 4 is an explanatory diagram of processing performed by a state control unit; 2 is a block diagram showing the electrical configuration of the information processing device; FIG. FIG. 9 is an explanatory diagram of another process performed by the state control unit; FIG. 9 is an explanatory diagram of another process performed by the state control unit; FIG. 4 is an explanatory diagram of specified objects;

An information processing apparatus that is an embodiment of the present invention has a CAD (Computer Aided Design) function that supports creation (including editing) of drawings such as blueprints. It also has a function of reading drawing data created by another information processing device (not shown) and editing the read data.

This example is an example in which the presence or absence of a plurality of objects whose lines overlap each other is checked, and if the existence is confirmed, the overlap of the lines is eliminated. Objects include lines (including straight lines, half lines, line segments, and curves), closed figures (such as triangles, rectangles, other polygons, and circles (including perfect circles and ellipses)). shall be configured. For example, when viewed on a display screen, an object that looks like a square but is composed of two lines, one U-shaped line and a line segment that closes the open part of this U-shaped object, Instead of a closed square figure, there are two objects: a U-shaped object and a line segment object forming one side of the square.

As shown in FIG. 1A, a plurality of objects OB1 to OB5 are arranged in a rectangular display area R1 on a display screen (not shown). In the display area R1, the origin and the coordinates on the xy plane with the x-axis in the horizontal direction and the y-axis in the vertical direction are set in advance, thereby providing absolute coordinates. The position of each point in the display area R1 is specified by coordinates on the xy plane. Although the x-axis and y-axis in this example are orthogonal, they may intersect at an angle different from 90°. In the following description, objects OB1 to OB5 are referred to as objects OB when they are not distinguished from each other.

The operator deletes or creates an object OB, or selects or modifies a specific object OB by clicking or selecting with a mouse or inputting a command (instruction) with a keyboard. When the operator performs an object designation operation for designating a plurality of objects OB using, for example, a mouse in order to check whether lines overlap in the display area R1, the object OB is designated based on this object designation operation. be done.

For example, among the objects OB1 to OB5, the rectangular object OB1, the line segment object OB2, and the perfect circle (hereinafter simply referred to as circle) object OB3 are to be specified. The object designation operation in this example is a region designation operation as shown in FIG. A region including all of the objects OB1 to OB3 is designated as a designated region R2. As a result, the objects OB1 to OB3 within the designated area R2 are designated. In the example shown in FIG. 1A, a rectangular rubber band area is specified as the specified area R2 by the amount of displacement (movement distance) of the cursor C along each of the x-axis and y-axis directions. A triangular object OB4 located so as to straddle the designated region R2 and the non-designated region R3, which is a region other than the designated region R2, is partly in the designated region R2, but the other part is in the non-designated region R3. It is not included in the specified region R2. Therefore, object OB4 is not specified. Also, the rectangular object OB5 included in the non-designated region R3 is not designated. The cursor C is composed of a cross cursor portion Ca in which two line segments are perpendicular to each other at the center and a square cursor box Cb centered at the position where these line segments intersect. is not particularly limited. Also, the intersection angle of the two line segments forming the cross cursor portion Ca may be other than 90°. Cursor box Cb is also called a trap box.

It is preferable that the specified objects OB1 to OB3 are highlighted so that they can be visually distinguished from the unspecified objects OB4 and OB5, and this is also the case in this example. In FIGS. 1B1 and 1B2, for convenience of explanation, the specified objects OB1 to OB3 are indicated by thick lines, and the unspecified objects OB4 and OB5 are indicated by thin lines. The thickness may differ from the example shown in FIG.

Here, it is assumed that the entire area of one side of the rectangular object OB1 extending in the lower horizontal direction in FIG. 1 and the partial area of the object OB2 of the line segment extending in the horizontal direction overlap with the line. do. In this case, when a plurality of objects OB1 to OB3 are specified, a horizontally extending overlapping area OL is detected (detection step). The overlapping area OL is an overlapping portion in which at least a portion of each line constituting each of the plurality of objects OB overlaps. It is an overlapping portion where each part overlaps with the line (line segment). Since the display order in the depth direction is set for the plurality of objects OB as will be described in detail later, the overlapping area OL is the overlapped portion displayed superimposed on each line of the two objects ordered in the depth direction in the display. be. The overlap region OL is preferably highlighted, and is so in this example. In FIGS. 1B1 and 1B2, the highlighting is indicated by hatching, but the actual highlighting is different from the illustrated mode, and the highlighting mode is different from other areas as described later. (Non-overlapping area excluding overlapping area OL) means a mode displayed so as to be identifiable, and is not particularly limited. In this example, the lines of the rectangular object OB1 and the circular object OB3 intersect each other at two points, and the lines do not overlap each other. Assume that they are not overlapping. Thus, line overlap does not include intersection at points.

Also, one of the objects OB1 and OB2 having the overlapping area OL among the objects OB1 to OB3 is selected (state control step). The process of making a selected state is a so-called activation process of setting the target for the next operation performed by the operator. The selected one is preferably highlighted to indicate the selected state, which is also the case in this example. For example, when the overlapping area OL is detected, the object OB1 is selected and highlighted as shown in FIG. 1B1. In FIG. 1B1, the highlighting is indicated by a dashed-dotted line for convenience, but the actual highlighting may differ from the illustrated mode.

When deleting the overlapping area OL of the object OB1, the operator performs an input operation for deleting the overlapping area OL with the mouse or keyboard when the object OB1 is in the selected state. As a result of this deletion, the rectangular object OB1 becomes a U-shape with an open bottom in FIG. 1(B1). When the overlapping area OL of the object OB1 is deleted, as shown in FIG. 1C, a display (bold line) indicating the designated state and a selection state of the overlapping area OL and the object OB1 are displayed. Each highlighting is canceled and the same display mode as before the designation is restored. In this way, the operator generates objects OB1 to OB3 whose lines do not overlap each other, and objects OB1 to OB5 are displayed on the screen (display control step).

When the object OB1 is in the selected state, the operator switches the selected state to the object OB2 in order to delete the overlapping area OL of the object OB2. The switching operation can be performed, for example, by positioning the cursor C so that the cursor box Cb is on the overlapping area OL and performing an operation assigned to the switching operation in that state. The assigned operation is, for example, right-clicking the mouse while holding down the control key (“Ctrl” key) on the keyboard. By this switching operation, as shown in FIG. 1B2, object OB2 is displayed in the same selected state as object OB1 in FIG. The display is similar to that of the object OB2 in B1). In this way, when object OB2 is in the selected state, the operator can delete overlapping area OL in object OB2 by performing an input operation that means deleting overlapping area OL in object OB2. , the deletion causes the line segment object OB2 to become a shorter line segment. As a result, the line overlap between the object OB1 and the object OB2 is eliminated, and the overlapping area OL disappears. When the object OB2 is shortened, as shown in FIG. 1C, the objects OB1 to OB3 are returned to the same display mode as before they were specified, as in the case of FIG. Objects OB1 to OB3 that do not exist are generated, and the display control step is performed.

In FIG. 2, the information processing device 11 is composed of a general computer, and performs processing based on the operator's operation by executing a predetermined program. Information processing device 11 is connected to operation unit 12 and display unit 13 . The operation unit 12 includes, for example, a keyboard, a mouse, and the like, and the operator performs various operations such as deletion of objects, generation of new objects, designation of objects, editing such as correction and division, and switching of objects to be selected. An instruction input operation is performed. The display unit 13 is, for example, a liquid crystal display. The information processing device 11 performs processing based on the input of the operation unit 12 and causes the display unit 13 to display. Note that the information processing device 11 may include an operation unit 12 and a display unit 13 .

The information processing apparatus 11 includes a creation/editing section 21 , an object designating section 22 , an overlap detecting section 23 , a state control section 26 and a display control section 27 . The information processing apparatus 11 preferably further includes a priority order setting unit 31 and a storage unit 32, which is also the case in this example.

The creating/editing unit 21 deletes or edits the generated object, creates a new object, etc. based on the input from the operation unit 12 , and outputs the result to the display control unit 27 . The display control unit 27 causes the display unit 13 to display based on the information input from the creating/editing unit 21 . The display control unit 27 is connected to the object designation unit 22, the overlap detection unit 23, and the state control unit 26, respectively. is displayed on the display unit 13 in the same manner as .

When an instruction to designate an object is input through the operation unit 12 , the object designation unit 22 designates the designated object and outputs it to the display control unit 27 and the overlap detection unit 23 . For example, as described above with reference to FIG. 1, when an instruction to designate an object OB using area designation is input through the operation unit 12, the object designation unit 22 selects objects OB1 to OB included in the designated area R2. Designate OB3 and place it in the designated state. Designation information indicating that the objects OB1 to OB3 are in the designated state is output to the display control unit 27 and the overlap detection unit 23 .

The overlap detection unit 23 detects overlapping areas of lines in a plurality of designated objects when the designation information is input from the object designation unit 22 . That is, the overlap detection unit 23 detects an overlap area OL where the lines of at least two of the objects OB1 to OB3 overlap each other. When there are a plurality of overlapping areas OL, it is preferable to detect these overlapping areas OL, and this example also does so. Overlap detector 23 outputs the detected overlap region OL to display controller 27 and state controller 26, respectively. In the overlapping region OL, lines extending in a specific direction do not have to strictly overlap each other. For example, a permissible range may be set for the degree of deviation, and even if there is deviation within the set permissible range, it may be regarded as overlapping and detected as an overlapping region OL, which is also the case in this example. For example, in a region R2 (xy plane) whose coordinates are specified by (x, y), point A (1.00, 1.00), point B (3.00, 1.00), point C (1 . 00, 1.01) and point D (4.00, 1.01), line segment AB and line segment CD are slightly deviated in the y-axis direction. Strictly speaking, the two lines do not overlap, but in this example, an allowable range is provided for the degree of deviation, and the overlapping area OL is detected by regarding these lines as "overlapping".

When the overlapping area OL is input, the state control unit 26 selects one of the object OB1 and the object OB2 having the overlapping area OL. For example, when the object OB1 is selected, the object OB1 is selected. Selection information indicating the selected state is output to the display control unit 27 . When the object OB2 is selected, information indicating that the object OB2 is selected is output to the display control unit 27 as selection information. If the overlapping area OL is an area where the lines of n (n is a natural number equal to or greater than 2) objects are overlapped, the state control unit 26 selects a part of the n objects, that is, one or more A number of objects in the range of (n-1) or less may be selected.

It may be configured to be able to set the priority to be in the selected state. The priority may be set in advance. If the priority is set in advance, the setting may be changeable according to the operator's designation, and the priority is stored in the storage unit 32 . When the overlapping area OL is input, the state control unit 26 reads the priority from the storage unit 32, specifies the object with the highest priority based on the priority, and puts the specified object in the selected state. Further, when an instruction to set the priority order to be placed in the selected state is input from the operation unit 12, some of the objects having the highest specified priority order may be placed in the selected state in response to the input. The priority of objects to be selected is preferably set based on, for example, the priority of attributes of the objects. The priority of attributes will be described later using another drawing.

The state control unit 26 switches the selection state to another object in response to the switching operation when the operation unit 12 performs a switching operation to switch the selection state to another object. Specifically, when any one object is in the selected state, a switching instruction to switch the selected state to another object is input to the state control unit 26 by a switching operation, and the state control unit 26 receives the switching instruction. Switch the selection state to other objects in response to input.

When a plurality of overlapping areas OL are input, it is preferable to select some of the objects in each of the plurality of objects forming the overlapping area OL, which is also the case in this example. Details of the state control unit 26 when a plurality of overlapping regions OL are input will be described later using another drawing.

The display control unit 27 preferably causes the display unit 13 to highlight the objects OB1 to OB3 based on the designation information input from the object designation unit 22. FIG. When the overlapping area OL is input, the display control unit 27 preferably causes the display unit 13 to highlight the overlapping area OL as shown in FIGS. 1B1 and 1B2. For example, when selection information indicating that the object OB1 is in a selected state is input, the display control unit 27 can cause the display unit 13 to highlight the object OB1 as shown in FIG. 1B1. preferable. In this manner, the display control unit 27 preferably causes the display unit 13 to highlight the object in the selected state.

The highlighting is for visually distinguishing from other objects or other regions, and any display that can be distinguished from other objects or other regions may be used. That is, the highlighted display of the objects OB1 to OB3 in the specified state is a display that can be distinguished from the objects OB4 to PB5 in the unspecified state. Also, the highlighted display of the overlapping area OL is a display that can be distinguished from the non-overlapping area in each of the object OB1 and the object OB2. Highlighted display indicating a selected state is a display that can be distinguished from an object that is not in a selected state. For highlighting, the line thickness, line color (hue, saturation, brightness), line type (solid line, chain line (one-dot chain line, two-dot chain line), etc.) are different from those to be discriminated, and the background color is There are various types of display, such as highlight display that is changed by reversing or the like, and display of a mark of a specific shape at an end point, for example. Examples of the specific shape mark include a rectangular mark (□). In the case of the overlapping area OL, a □ mark is displayed at each end point of the overlapping area OL. For example, a □ mark is displayed at the center of each vertex and each side of . In addition, highlighting is a display that can be distinguished from other objects and other areas. It can also be realized by displaying each object that is not inconspicuous. For example, the non-specified objects, non-overlapping areas, and non-selected objects may be made more transparent, or made lighter or closer to the background color. By changing the display of other objects to be determined in this manner, this display can be used as a highlight display for each of the designated state, the overlapping area OL, and the selected state. Also, highlighting according to the line type may be used. For example, in the case of an overlapping region OL where a solid line and a dashed-dotted line overlap, the solid line may be highlighted when the solid line is selected, and the dashed-dotted line may be highlighted when the dashed-dotted line is selected.

The priority order setting unit 31 sets the priority order for the selected state based on the input from the operation unit 12 as the priority order for the selected state of the attribute of the object, and the storage unit 32 be memorized. As a result, the priority of the objects to be set in the selected state in the state control section 26 can be changed by the operation of the operator.

The priority of object attributes will be described with reference to FIG. Object attributes include, for example, object creation order, line type, line thickness, display order, layer number (hereinafter referred to as image number), etc. One of these attributes is selected. The state control unit 26 specifies the object to be in the selected state based on the set attribute. Attributes may be pre-selected and defaulted. The attributes may be selected and set by the operator if they have not been initialized, or may be reset (changed) by the operator if they have been initialized. A setting (including resetting) operation by the operator is input of a selection instruction to select a specific attribute using the operation unit 12. Setting using the operation unit 12 when at least one object is in a selected state. When an operation is performed, the state control unit 26 may respond to the setting operation and change the object based on the setting operation. When the attribute is set by the operation unit 12, the display image such as the command menu corresponding to the command specifying the attribute of the selection candidate is displayed on the display unit 13 under the control of the state control unit 26. may be displayed in As a result, the operator places the cursor C, for example, on the display of the command corresponding to the attribute to be selected in the command menu, for example, and clicks it, or inputs a command designating the attribute to be selected using the keyboard. , it is possible to switch the priority of attributes and set the priority of objects to be selected. In this way, when the operator sets the attribute, the priority order setting unit 31, when a selection instruction to select the attribute of the object is input from the operation unit 12, based on the input selection instruction. Set to a specific attribute.

Each attribute is given a priority (rank within the attribute). Note that the attribute ranking may also be initially set, or may be set (including reset) by the operator using the operation unit 12 via the priority setting unit 31 . The order of priority in the object generation order is the order of precedence and succession on the time axis. As shown in FIG. objects that have been created, that is, objects whose generation timing is old are selected. The line type of the object is a solid line, a chain line (chain line, two-dot chain line), etc. FIG. Also, FIG. 3 shows a case where an object with a relatively thin thickness is given a higher priority than an object with a thicker thickness. Here, for example, it is assumed that three objects each composed of lines of 0.2 mm, 0.3 mm, and 0.4 mm have an overlapping area OL. The state control unit 26 selects the object composed of the thinnest 0.2 mm line, and when an instruction to switch the selected object is input, selects the object composed of the 0.2 mm line. , the selection state is switched to an object composed of 0.3 mm lines, and when the next switching instruction is input, the selection state is switched to the object composed of the thickest 0.4 mm lines. .

The display order in the depth direction is set for the plurality of objects OB, and the display order of two objects is never the same. Therefore, any two objects among the plurality of objects are positioned one on the front (upper) side and the other on the back (lower) side in display order. FIG. 3 shows a case where the rear side is given a higher priority than the front side.

The layer number is for specifying a layer when the display area R1 (see FIG. 1) is composed of a plurality of layers. Therefore, the layer number may be replaced with other layer specifying contents as long as each layer can be specified. An object exists in one of multiple layers, and these multiple layers overlap in the depth direction. Layer numbers can be used to set priorities. FIG. 3 shows a case where layers with relatively low layer numbers are given higher priority than layers with high layer numbers. If a plurality of objects exist on the same layer, the attribute priority may be set in combination with other attributes.

The state control unit 26 when a plurality of overlapping areas OL are input will be described with reference to FIG. It is assumed that three overlapping areas OL of the first overlapping area OL1 to the third overlapping area OL3 are input from the overlap detection unit 23. FIG. In FIG. 4, for convenience of explanation, lines are drawn as rectangles with width, and the first overlapping area OL1 to the third overlapping area OL3 are indicated by hatching. Note that the highlighting of the first overlapping area OL1 to the third overlapping area OL3 may be the same or different. The first overlap area OL1 is an area where the lines of the object OBa1 and the object OBb1 overlap, the second overlap area OL2 is an area where the lines of the object OBa2 and the object OBb2 overlap, and the third overlap area OL3 is an area where the object OBa3 and the object OBa3 overlap. It is assumed that the line with the object OBb3 overlaps with the area.

The state control unit 26 selects one of the objects, for example, the object OBb1 as shown in FIG. 4A, in the first object group consisting of the object OBa1 and the object OBb1. Similarly, one of the second object group consisting of object OBa2 and object OBb2 and the third object group consisting of object OBa3 and object OBb3 is selected. For example, as shown in FIG. 4A, the object OBa2 in the second object group and the object OBb3 in the third object group are selected. When the first to third object groups consist of three or more objects, two or more objects may be selected if the lines of the three or more objects overlap. In the case of a configuration in which the objects can be switched, it is preferable to select only one object because the operator can easily determine the target of deleting the overlapping area OL for each object and perform the deletion operation.

As described above, when any one object in one of a plurality of object groups is in the selected state, when an operation to switch the selected object is input from the operation unit 12, this In response to the input, the state control unit 26 preferably switches the selection state to other objects in the group. For example, as shown in FIG. 4A, when the object OBa2 is selected in the second object group, the cursor C is placed on the overlapping area OL and a predetermined operation is performed on the operation unit 12, for example, by pressing the keyboard. When the mouse is right-clicked (Ctrl+right-clicked) while the control key is pressed, the state control unit 26 selects the object OBb2 of the second object group and selects it as shown in FIG. 4B. Deselect the object OBa2. Further, as shown in FIG. 4B, when the object OBb2 is in the selected state in the second object group, when a similar switching operation is performed, the state control unit 26 changes the state as shown in FIG. Secondly, the object in the selected state is switched by selecting the object OBa2 and canceling the selected state of the object OBb2. Note that the switching operation is not limited to the combination operation of the keyboard and the mouse in this example, and may be an operation of either one. Even if the selection state is switched from one of object OBa2 and object OBb2 to the other in the second object group, the selection state of object OB in the first object group and the second object group is not switched. In this way, when switching the selection state of the object OB in a part of the plurality of object groups, the selection state of the object OB in the other object group may be maintained. It should be noted that in some object groups among a plurality of object groups, the selection state of the object OB may be canceled while the selection state of the object OB in the other object group is maintained. It is preferable to assign an operation different from the switching operation to the release operation.

In the above example, the selection state of the object OB is switched in the second object group, but the object OB may be switched in each of the first object group and the third object group. When switching the object OB in a plurality of object groups, it is preferable to switch the selection state sequentially such as one object group and then another object group. In this way, when there are a plurality of object groups, each of the plurality of object groups can be configured to switch the object OB independently.

The information processing apparatus 11 is realized by installing an OS (Operating System) for the processing apparatus and an information processing program that runs on the OS in a computer (for example, a PC (Personal Computer) or the like). The information processing apparatus 11 functions as each of the units described above by executing the information processing program.

The OS for the processing device may be pre-installed in the computer, or may be recorded on a recording medium such as a CD (Compact Disc), a DVD (Digital Versatile Disk), an MO disk (Magneto-Optical disk), or a flash memory. It may be distributed in the state of being printed and read into a computer from the recording medium.

The information processing program may be distributed in a state recorded on a recording medium such as a CD, DVD, MO disk, flash memory, etc., and read into the processing device from the recording medium, or may be read from the server device of the supply source via a communication network. Alternatively, it may be supplied to the computer via a communication network from a server device that manages the number of licenses that can be activated simultaneously.

The information processing program causes the computer to execute a detection step (detection process), a state control step (state control process), and a display control step (display control process). The detecting step detects overlapping regions of lines in the specified objects. The state control step selects some of the plurality of objects having the overlapping area when the overlapping area is detected. The display control step causes the display unit to display the plurality of objects.

For example, as shown in FIG. 5, the electrical configuration of the information processing apparatus includes a control processing unit 51 including a CPU (Central Processing Unit) and a ROM (Read Only Memory), and a main storage device 52 including a RAM (Random Access Memory). , an auxiliary storage device 53 including a HDD (Hard Disc Drive), an input device 54 including various pointing devices (such as a mouse) and a keyboard, an output device 55 including a display and a speaker, and a network interface card. and a communication control device 56 including

The main storage device 52, auxiliary storage device 53, input device 54, output device 55, and communication control device 56 are each connected to the control processing device 51 via a bus line. The control processing device 51 (1) loads the information processing program stored in the auxiliary storage device 53 into the main storage device 52, and (2) follows the instruction of the information processing program to input the input device 540, the auxiliary storage device 53, and the communication control device. 56, (3) computing and processing the acquired data according to the procedure specified in the information processing program, and (4) storing the computed and processed data in the auxiliary storage device 53. and at least one of the output device 55 and the communication control device 56 .

The operation unit 12 (see FIG. 2) includes an input device 54, and the display unit 13 (see FIG. 2) includes an output device 55. FIG. That is, when the information processing apparatus 11 includes the operation unit 12 and the display unit 13, the information processing apparatus 11 includes an input device 54 and an output device 55 as shown in FIG. 13, the input device 54 and output device 55 may not be included. The overlap detection unit 23 (see FIG. 2) includes a control processing unit 51, and the creating/editing unit 21, the object designating unit 22, the state control unit 26, and the priority order setting unit 31 (see FIG. 2) are all included in the control processing unit. 51 and communication controller 56 . The storage unit 32 (see FIG. 2) includes a main storage device 52 and an auxiliary storage device 53 .

The operation of the above configuration will be explained. The creating/editing unit 21 creates and edits an object in response to an instruction operation to create or edit an object on the operation unit 12 , and the created or edited object is displayed on the display unit 13 by a display control unit 27 . to be displayed.

The object designation unit 22, in response to input of an object designation instruction from the operation unit 12, puts the designated object into a designated state. For example, in the present example shown in FIG. 1, the objects OB1 to OB3 included in the designated region R2 are specified, and the specified information is output to the display control unit 27 after the specified state. The display control unit 27 causes the display unit 13 to highlight the objects OB1 to OB3 in response to the input of the designation information.

The object designation unit 22 outputs the designation information to the overlap detection unit 23 after generating the designation information. good too. Overlap detection unit 23 detects the overlap region OL in response to the input of the designation information, and outputs it to display control unit 27 and state control unit 26 . When there are multiple overlapping areas OL, the multiple overlapping areas OL are detected and similarly output to the display control unit 27 and the state control unit 26, respectively. The display control unit 27 causes the display unit 13 to highlight the overlapping area OL in response to the input of the overlapping area OL.

In response to the input of the overlapping area OL, the state control unit 26 reads, for example, the storage unit 32, and if the priority of the attributes of the object is set in advance as the priority of the object to be placed in the selected state, the Based on the order of priority, if not set, for example, one of the object OB1 and the object OB2 having the overlapping area OL is arbitrarily selected. Further, when the priority of the attributes of the objects is input from the operation unit 12 after the overlapping area OL is input, the state control unit 26 responds to the input and selects one of the objects based on the priority. be selected.

Since the overlapping area OL is detected and some of the objects OB1 and OB2 having the overlapping area OL are selected, the selected objects are displayed in a manner different from the unselected objects. Easier to set. Therefore, the operator can grasp the overlapping area OL in advance and predict the processing result. Therefore, a necessary operation can be performed based on the predicted processing result, and the overlapping area can be processed without unnecessary operations. Thus, the information processing apparatus 11 has good operability.

Even when multiple overlapping areas OL are detected, the state control unit 26 similarly processes each individual object group. Therefore, the greater the number of overlapping areas OL, the more the operator can avoid unnecessary operations, and the better the operability is.

For example, when the object OB1 is selected, the selection information is output to the display control section 27, and the object OB1 is highlighted on the display section 13 as shown in FIG. 1(B1). Since the object OB1 in the selected state is highlighted, the visibility is good, the next operation can be determined quickly, and the operability is better. For example, it is possible to quickly determine the necessity of a switching operation or canceling operation of an object in the selected state.

After that, when a switching operation of the object in the selected state is performed on the operation unit 12, the state control unit 26 switches the selected state to another object in response to the switching operation. Since the selected object can be switched, it is possible to process the overlapping area OL while leaving the target area of the target object with lines of desired attributes.

When the priority of the attribute of the object is input by the operation unit 12 as the priority for the selected state, the priority for the selected state is set by the priority setting unit 31 and stored in the storage unit 32 . Therefore, the priority of objects to be selected is set in advance, and the target object is selected in subsequent state control steps. Therefore, the object scheduled for the next operation can be determined at a faster timing, and the operability is further improved in terms of efficiency.

When a target object is selected and, for example, a deletion instruction to delete the overlapping area OL is input through the operation unit 12, the creating/editing unit 21 deletes the overlapping area OL in the selected object, and aligns the lines with each other. Make multiple objects without overlapping. At this time, highlighting is canceled in both the designated state and the selected state of the object. In this way, a drawing composed of a plurality of objects is obtained.

Although the object OB is selected in the above example, the overlapping area OL may be selected. In that case, when the overlapping area OL is detected, the state control unit 26 selects one of the plurality of objects having the overlapping area instead of selecting some of the objects having the overlapping area. The overlapping area OL in the partial object is divided from the non-overlapping area and put into a selected state (state control step). Such an information processing apparatus 11 performs the state control step of the information processing program to be executed by the computer, instead of the state control step described above, when the overlapping region OL is detected, out of the plurality of objects having the overlapping region. It is preferable to divide the overlapping area OL in some objects from the non-overlapping area and put them in a selected state.

A specific description will be given with reference to FIG. Assume that the fourth overlap region OL4 is input from the overlap detector 23 . In FIG. 6, for convenience of explanation, lines are drawn as wide rectangles, and the fourth overlap region OL4 is indicated by hatching. The fourth overlapping area OL4 is assumed to be an area where the lines of the object OBa4 and the object OBb4 are overlapped. The order of priority for the selected state may be configured to be set in the same manner as in the above example. In this example, it is assumed that the order of priority is set in advance, and the order of display of the attributes of the object is relatively higher in the front side than in the back side. It is assumed that object OBa4 exists in front of object OBb4 in the display order.

When the fourth overlapping area OL4 is input, the state control unit 26, in response to this input, changes the fourth overlapping area OL4 in the object OBa4 having the higher priority between the object OBa4 and the object OBb4. As shown in (A1), the object OBa4 is divided into a fourth overlapping area OL4 and a non-overlapping area while being in a selected state. In FIGS. 6A1 and 6B1, the dividing line is labeled SL, and this dividing line SL corresponds to the end point between the fourth overlapping area OL4 and the non-overlapping area. Note that the boundary line between the fourth overlapping region OL4 and the non-overlapping region in each of the object OBb4 in FIG. 6A1 and the object OBa4 in FIG. It is shown as When the fourth overlapping area OL4 of the object OBa4 is selected, selection information indicating that the fourth overlapping area OL4 of the object OBa4 is selected is output to the display control unit 27. FIG.

When, for example, an instruction to delete the overlapping area is input by the operation unit 12 while the fourth overlapping area OL4 of the object OBa4 is in the selected state, the creating/editing unit 21 responds to the input by creating the fourth overlapping area of the object OBa4. Area OL4 is deleted as shown in FIG. 6(A2).

The state control unit 26 switches the selection state to the overlapping area of the other object in response to the switching operation when the operation unit 12 performs a switching operation to switch the selection state to the overlapping area of the other object. Specifically, when the fourth overlapping area OL4 of the object OBa4 is in the selected state, a switching instruction to switch the selected state to the fourth overlapping area OL4 of the object OBb4 is input to the state control unit 26 by the switching operation. Then, in response to the input of the switching instruction, the state control unit 26 switches the selection state to the fourth overlapping area OL4 of the object OBb4, as shown in FIG. 6B1. If a switching operation is similarly performed in this state, the selection state is switched again to the state of FIG. 6 (A1). For example, when an instruction to delete the overlapping region is input through the operation unit 12 while the fourth overlapping region OL4 of the object OBb4 is in the selected state, the creating/editing unit 21 responds to the input by creating the fourth overlapping region of the object OBb4. The area OL4 is deleted as shown in FIG. 6(B2).

If the fourth overlapping area OL4 is an area where the lines of n (n is a natural number equal to or greater than 2) objects are overlapped, the state control unit 26 determines that some of the n objects overlap. A region, that is, an overlapping region in a number of objects ranging from 1 to (n-1), may be selected.

When the fourth overlapping area OL4 is input, the display control unit 27 can display the fourth overlapping area OL4 in a state divided from the non-overlapping area as shown in FIG. 6 (A1) or (B1). Preferably, it is more preferable to highlight the fourth overlapping area OL4. For example, when the selection information indicating that the fourth overlapping area OL4 of the object OBa4 is selected, the display control unit 27 displays the fourth overlapping area of the object OBa4 as shown in FIG. 6A1. It is preferable to highlight OL4 on the display unit 13 . In this manner, the display control unit 27 preferably causes the display unit 13 to highlight the overlapping area of the selected objects.

Since the overlapping area OL4 is detected and the fourth overlapping area OL4 of the object OBa4 is selected, the fourth overlapping area OL4 of the selected object OBa4 is combined with the fourth overlapping area OL4 of the unselected object OBb4. The process of setting to display in different modes is facilitated. Also, since the object OBa4 is divided into the fourth overlapping area OL4 and the non-overlapping area, it is easy to grasp the dividing position. Therefore, the operator can grasp the fourth overlapping area OL4 in advance and predict the processing result such as which object's fourth overlapping area will be processed. Therefore, it is possible to perform a necessary operation such as a switching operation for the fourth overlapping area OL4 based on the predicted processing result, and it is possible to process the fourth overlapping area OL4 without unnecessary operations. Thus, the information processing apparatus 11 has good operability.

Note that when a plurality of overlapping areas OL are input, it is preferable to select the overlapping area OL of some of the objects in each of the plurality of objects forming the overlapping area OL. In addition, in one group of a plurality of object groups, when the overlapping area OL in any one object is in the selected state, the state control unit 26 responds to the switching operation to switch the overlapping area OL to be in the selected state. Then, it is preferable to switch the selection state to the overlapping area OL of the other objects in the one group.

The state control unit 26 preferably cancels the division into the overlapping area OL and the non-overlapping area OL when the selection state of the overlapping area OL is canceled, and this example also does so. This eliminates the need for a useless operation for designating the cancellation of division, so the operability is better.

When any one of the objects is in a split state, the state control unit 26 preferably switches the split state to another object in response to a switching operation for switching the object to be in the split state. . Switching of the divided state is preferably performed together with switching of the overlapping region. As described above, when the overlapping area of any one object is divided from the non-overlapping area and is in the selected state, the state control unit 26 responds to the switching operation to switch the object having the overlapping area to be in the selected state. , the overlapping area may be divided and the selection state may be switched to another object.

When the overlapping area OL is detected, the state control unit 26 may divide the overlapping area OL in each of the plurality of objects having the overlapping area from the non-overlapping area. In this case, one of the overlapping regions OL may be put in the selected state. Taking the above objects OBa4 and OBb4 as examples, the state control unit 26 divides each of the objects OBa4 and OBb4 into a fourth overlapping area OL4 and a non-overlapping area, as shown in FIG. and, for example, the fourth overlapping area OL is brought into a selected state. In this state, when an overlapping area deletion instruction is input through the operation unit 12, the creating/editing unit 21 deletes the fourth overlapping area OL4 between the object OBa4 and the object OBb4 in response to the input. Then, the creating/editing unit 21 creates an object OBc4 composed of lines having the same length and shape as those of the fourth overlapping area OL4 with the same attributes as the object OBa4 of the fourth overlapping area OL4, which has been in the selected state, as shown in FIG. 7(B). Generate as shown. In this example, the display order is set so that the newly generated object OBc4 is positioned on the frontmost side, but the display order and layer of the newly generated object OBc4 are not particularly limited.

In each of the above examples, the object specifying operation is the region specifying operation, but the object specifying operation may be the intersection specifying operation. The intersection specifying operation is an operation in which an object OB contained in the specified region R2 and an object OB intersecting the outline of the specified region are specified by similarly specifying the specified region R2 by displacing the cursor C. is. For example, an overlapping area OL detected when an object designating operation using an intersection designating operation is performed on objects OB1 to OB5 shown in FIG. 1 will be described with reference to FIG. In FIG. 8, the specified objects OB1 to OB3 are indicated by thick lines, the unspecified objects OB4 and OB5 are indicated by thin lines, and the overlapping area OL is indicated by hatching. However, the selected state and the non-selected state of the specified object OB are drawn by solid lines without distinguishing between them in order to avoid complication of the drawing.

As shown in FIG. 8A, the object OB1 is contained in the specified region R2, and the objects OB2 to OB4 are positioned so as to straddle the specified region R2 and the non-specified region R3, that is, along the outline of the specified region R2. If they intersect, any of the objects OB1-OB4 are designated. As shown in FIG. 8B, object OB2 is contained in designated region R2, object OB1 is positioned across designated region R2 and non-designated region R3, and objects OB3 and OB4 are positioned within non-designated region R3. If they fit, objects OB1 and OB2 are specified, and objects 3 and OB4 are not specified.

As shown in FIG. 8C, when each of the objects OB1, OB2, and OB4 is positioned across the designated region R2 and the non-designated region R3, and the object OB3 is within the non-designated region R3, Objects OB1, OB2, OB4 are specified, but object OB3 is not. Also, as shown in FIG. 8D, when some lines (line portions) of the objects OB1 and OB2 are positioned on the outline of the designated region R2, and the objects OB3 and OB4 are contained in the non-designated region R3. , objects OB1 and OB2 are specified, but objects OB3 and OB4 are not specified. In each of the examples of FIGS. 8A to 8D, both objects OB1 and OB2 are specified, so the overlapping area OL is detected in the same manner as in the area specifying operation.
