  The display unit 21, the user input receiving unit 22, and the component editing unit 23 are realized by reading the software program stored in the external storage device 4 to the main storage device 3 and executing it by the central processing unit 2.

  The display unit 21 performs display processing on the component edited by the component editing unit 23 and displays it on the display device 6. The user input receiving unit 22 receives the coordinates of the input point input from the input device 5, and receives the component editing unit. To 23.

Parts are obtained.

<Overall editing process>
Next, a processing procedure in the drawing editing apparatus 100 when editing a multi-track component will be described. FIG. 4 is a flowchart showing the overall flow of the multi-line component editing process.

  First, when the editing mode is set to “ON”, the drawing editing apparatus 100 starts processing (step ST101). Various modes are selectably displayed on the input screen opened on the display device 6, and the edit modes “ON” and “OFF” can be set based on the input screen.

  After the edit mode is set to “ON”, an event wait state is entered (step ST102). Here, the event corresponds to an input from the input device 5, and the event information is passed to the user input receiving unit 22.

  When an event occurs, the user input reception unit 22 determines the event (step ST103).

  Here, Table 1 shows a list of events that occur during component selection.

  In Table 1, “-” indicates an invalid event or an event that cannot occur. The event that has occurred is determined by the type of the part being selected and the conditions at the time of the event occurrence.

  Table 1 shows the conditions when a mouse is used as the input device 5 and a menu such as “Generate double-tracked parts” is in the pull-down menu displayed from the menu bar of the drawing editing device. Yes. For example, if the position clicked with the left mouse button is “Generate double-line component” in the pull-down menu displayed from the menu bar of the drawing editing apparatus, a “Double-line component generation” event occurs.

  Note that an equivalent event also occurs when a keyboard is used as the input device 5 and the “double-line component generation” menu is selected using the keyboard. In addition, a menu such as “Create multi-track part” may be in a pop-up menu.

  In Table 1, an event is generated by the mouse, and the mouse event is classified into “click the left button”, “start dragging with the left button”, and “others”.

  Examples of events include “double line parts generation”, “vertex display”, “double line parts conversion”, “core line display”, “individual part conversion”, “double line conversion parts deformation”, and “normal processing”. ing.

  In Table 1, when the selection target part is “one line segment sequence”, “double line parts generation” and “vertex display” are valid events, but other events are invalid events. Yes. Further, when the part to be selected is “a plurality of line segments”, it indicates that only “multi-lined parts” is an effective event. In addition, when the selection target part is "multiple parts", "core display", "individual parts" and "double line parts deformation" are valid events, but other events are invalid events. Show. In addition, when the selection target component is “other components”, only “vertex display” is an effective event. Note that the normal editing process and the end of editing are valid for any part to be selected.

  Here, returning to the description of FIG. 4, if the input event is a “double-line component generation” event as a result of the event determination in the user input reception unit 22, double-line component generation processing (step ST <b> 104) is executed. To do. If it is an “individual componentization” event, the individual componentization processing (step ST105) is executed. If it is a “double-track componentization” event, a double-track componentization process (step ST106) is executed. If it is a “core line display” event, a core line display process (step ST107) is executed. If it is a “double-line component deformation” event, a double-line component deformation process (step ST108) is executed. If the event is a “normal editing process” event, the editing process (step ST109) is executed, and the same editing process as the conventional one is performed.

  In the multi-track component generation process (step ST104), the multi-track component generation unit 2321 generates a multi-track component using the coordinates of the selected line segment component. Details of the processing will be described later.

  In the individual componentization processing (step ST105), the individual component conversion unit 2324 disassembles the selected multi-track component into individual components. Details of the processing will be described later.

  In the multi-track componentization process (step ST106), the multi-track component processing unit 2323 performs a process such as deforming a part so that the selected plurality of line segment components can be handled as a multi-track component. Details of the processing will be described later.

  The core line display process (step ST107) is acquired after the core line display unit 212 acquires the reference line segment component of the selected multi-line component from the multi-line control component information storage unit 25 via the component editing unit 23. The coordinates of the reference line segment component thus obtained are acquired from the component information storage unit 24 via the component editing unit 23. Then, the position of the core line is determined using the coordinates of the reference line segment component.

  In the double-track component deformation process (step ST108), the double-track component deforming unit 2322 deforms the double-track component according to the deformation state of the core wire of the selected double-track component. Details of the processing will be described later.

  In the editing process (step ST109), the conventional component editing unit 231 performs the specified editing process. The contents of the processing are the same as those of the conventional drawing editing apparatus.

  After executing any of the above processes, the display unit 21 displays each component edited in steps ST104 to 109 on the display device 6 in step ST110.

  If the input event is a “vertex display” event, the process proceeds to step ST110 to display the vertex on the display device 6. The processing for displaying the vertices is the same as in the conventional drawing editing apparatus. If the event is an “edit end” event, the process is terminated by setting the edit mode to OFF. For an event that occurs when a part is not selected, the same processing as in a conventional drawing editing apparatus is performed. After step ST110, the process returns to the event waiting state of step ST102.

  In this way, the processes from step ST102 to step ST110 are repeated until the edit mode is set to OFF.

<Double track parts generation processing>
Hereinafter, details of the double-track component generation processing in step ST104 shown in FIG. 4 will be described using the flowchart shown in FIG.

  In the double track component generation process, first, the double track component generation unit 2321 generates a double track control component (step ST1041). A multi-track control part is a part that manages and controls the line segment parts that make up a multi-line part. When a multi-line part is edited, the line segment parts that make up the multi-line part This is a part for batch editing. It has information on the line segment components constituting the double track components and information such as which reference line segment components are present, and there is one for each multi track component.

  Next, the double track component generation unit 2321 acquires the information on the number of double tracks input from the input device 5 via the user input receiving unit 22 (step ST1042).

  Next, the double-track component generation unit 2321 generates parallel line segment components for the number (number -1 acquired in step ST1042) (step ST1043).

  Next, the double line component generation unit 2321 registers the selected line segment component and the information of the parallel line segment generated in step ST1043 in the double line control component, and also selects the line segment component being selected. Is registered in the double track control part as a reference line segment part. Then, the information of the obtained double track control component is stored in the double track control component information storage unit 25 (step ST1044).

  Next, the multi-line component generation unit 2321 acquires the coordinates of the reference line segment component from the component information storage unit 24 (step ST1045).

  Next, the double track component generation unit 2321 passes the double track control component generated in step ST1041 and the coordinates of the reference line segment acquired in step ST1045 to the double track component coordinate calculation unit 2325, and uses the information. The multi-line component coordinate calculation unit 2325 calculates the coordinates of the parallel line segment components (step ST1046). Details of this processing will be described later.

  Finally, information such as coordinates relating to the multi-line component calculated in step ST1046 is transferred to the display unit 21 and stored in the component information storage unit 24 (step ST1047).

  Note that the reference line segment component is used at the time of generating the double-tracked component, but may be specified again by the user after the generation of the double-tracked component.

<Individual parts processing>
Next, details of the individual componentization processing in step ST105 shown in FIG. 4 will be described using the flowchart shown in FIG.

  In the individual part conversion processing, first, the individual part conversion unit 2324 obtains the multi-track control component of the selected multi-track component from the multi-track control component information storage unit 25 (step ST1051).

  Next, the individual component converting unit 2324 deletes the double track control component acquired in step ST1051 (step ST1052), and passes only the coordinate information of the selected multitrack component to the display unit 21.

  The multi-track control component is a component for managing the line segment components constituting the multi-track component together. For example, the multi-track control component has a function of bundling a plurality of multi-track components, but is not displayed. . By deleting this, the line segment parts constituting the double-line parts can be handled as individual parts.

<Double line parts processing>
Next, details of the double-track componentization processing in step ST106 shown in FIG. 4 will be described using the flowchart shown in FIG.

  In the multi-track componentization process, first, the multi-track component processing unit 2323 generates a multi-track control component for grouping (step ST1061).

  The multi-track control component is a component for grouping so that the editing with respect to the reference line segment component also extends to the parallel line segment component.

  Next, the multi-line component processing unit 2323 uses the coordinates of the plurality of line segment components being selected as a reference for the line segment component located closest to the center of the plurality of line segment components being selected. The line segment parts are determined (step ST1062). The above determination method is based on a predetermined determination condition that the line segment component located closest to the center of the plurality of line segment components is determined as the reference line segment component. The conditions for determining the sorting components are not limited to this.

  By determining the determination conditions in advance, it is possible to automatically determine the reference line segment parts and save the user's trouble.

  The reference line segment component may be arbitrarily designated by the user. Thereby, the user can freely specify the reference line segment parts.

  Next, the multi-track componentization processing unit 2323 registers a plurality of line segment components being selected in the multi-track control component generated in step ST1061, and information on the reference line segment components determined in step ST1062 Register to the double track control part. Then, the information of the obtained double track control component is stored in the double track control component information storage unit 25 (step ST1063).

  Next, the multi-track componentization processing unit passes the multi-track control component generated in step ST1061 and the coordinates of the reference line segment determined in step ST1062 to the multi-track component coordinate calculation unit 2325, and uses the information. The multi-line component coordinate calculation unit 2325 calculates the coordinates of the parallel line segment components (step ST1064). Details of this processing will be described later.

  Finally, information such as coordinates relating to the multi-line component calculated in step ST1064 is transferred to the display unit 21 and stored in the component information storage unit 24 (step ST1065).

  By providing the double-track componentization processing unit 2323, it is possible to make a double-track component even if it is not a component generated as a double-track component. Editing of parts can be performed, and the user's editing work is reduced.

<Double line parts deformation processing>
Next, the details of the multi-line component deformation process in step ST108 shown in FIG. 4 will be described using the flowchart shown in FIG.

  In the double track component deformation process, first, the double track component deforming unit 2322 acquires a double track control component of the selected double track component from the double track control component information storage unit 25 (step ST1081).

  Next, the multi-line component deforming unit 2322 acquires the deformed coordinates of the reference line segment sequence from the component information storage unit 24 (step ST1082).

  Next, the double-track component deforming unit 2322 passes the multi-track control component acquired in step ST1081 and the coordinates of the reference line segment after deformation acquired in step ST1082 to the double-track component coordinate calculating unit 2325, and information thereof , The multi-line component coordinate calculation unit 2325 calculates the coordinates of the parallel line segment components (step ST1083). Details of this processing will be described later.

  Finally, the double-track component deforming unit 2322 passes information such as coordinates related to the multi-track component calculated in step ST1083 to the display unit 21 and stores the information in the component information storage unit 24 (step ST1084).

<Double-track component coordinate calculation processing>
Next, details of the multi-line component coordinate calculation processing described so far as steps ST1046 (FIG. 5), ST1064 (FIG. 7), and ST1084 (FIG. 8) will be described using the flowchart shown in FIG.

  In the double-track component coordinate calculation process, first, the multi-track component coordinate calculation unit 2325 acquires information on line segment components constituting the multi-track component from the information on the double track control component (step ST10).

  Next, the multi-line component coordinate calculation unit 2325 calculates the coordinates of the end points of the parallel line segment components using the coordinates of the reference line segment components and the line thickness information (step ST11). This process will be specifically described with reference to FIG.

  FIG. 10A shows a case where the line segment component 101 is a reference line segment component and the line segment components 102 and 103 are parallel line segment components. The line segment component 101 has points 1011 and 1014 as end points located at the ends of the line segment line, and points 1012 and 1013 as vertices (bending points) of the line segment line. Similarly, the line segment component 102 has points 1021 and 1024 as end points located at the ends of the line segment, and points 1022 and 1023 as vertices of the line segment. The line segment component 103 has points 1031 and 1034 as end points located at the ends of the line segment, and points 1032 and 1033 as vertices of the line segment.

  The line segment component 101 is a line segment passing through the points 1011 and 1012 as a line segment 1015, a line segment passing through the points 1012 and 1013 as a line segment 1016, and a line segment passing through the points 1013 and 1014 as a line segment. It has as minutes 1017. Similarly, the line segment component 102 has a line segment passing through the points 1021 and 1022 as a line segment 1025, a line segment passing through the points 1022 and 1023 as a line segment 1026, and a line segment passing through the points 1023 and 1024. It has as a line segment 1027. Further, the line segment component 103 sets a line segment passing through the points 1031 and 1032 as a line segment 1035, a line segment passing through the points 1032 and 1033 as a line segment 1036, and a line segment passing through the points 1033 and 1034 as a line. It has as 1037 minutes.

  When the coordinates of the end point 1021 of the line segment component 102 that is a parallel line segment component are calculated, the coordinates of the end point 1021 are obtained by the following procedure.

  First, as shown in part (b) of FIG. 10, a perpendicular line 10111 which is perpendicular to the line segment 1015 passing through the end point 1011 of the reference line segment component 101 and passes through the end point 1011 is obtained.

  Then, as shown in part (c) of FIG. 10, a point 10112 that is at a distance equal to the line thickness w of the line segment component 101 from the end point 1011 and is on the vertical line 10111 is obtained. The point 10112 becomes the end point 1021 of the parallel line segment component 102.

  In the same process, the coordinates of the end point 1024 of the parallel line segment component 102 and the end points 1031 and 1034 of the parallel line segment component 103 can also be obtained.

  FIG. 11 shows a case where the number of double lines is five. In FIG. 11A, the line segment component 111 is used as a reference line segment component, and the line segment component 112, A case where 113, 114 and 115 are parallel line segment parts is shown. Each of the line segment components 111, 112, 113, 114, and 115 has one end point 1111, 1121, 1131, 1141, and 1151, and the other end point 1114, 1124, 1134, 1144, and 1154.

  As shown in part (a) of FIG. 11, when there is another line segment part 112 that already forms a double-lined part next to the reference line segment part 111, the end point 1131 of the line segment part 113 is displayed. In order to obtain the coordinates, as shown in part (b) of FIG. 11, a point at a distance equal to the thickness w × number of lines may be obtained.

  Here, returning to the description of FIG. 9, the double-lined part coordinate calculation unit 2325 uses the coordinates of the reference line segment part and the coordinates of the end points obtained in step ST11 to obtain points other than the ends of the parallel line segment parts. Are calculated (step ST12). This process will be specifically described with reference to FIG.

  When the coordinates of the vertex 1022 of the parallel line segment component 102 are calculated using the line segment component 101 shown in part (a) of FIG. 10 as a reference line segment sequence, the coordinates of the point 1022 are obtained by the following procedure.

  First, as shown in part (d) of FIG. 10, the point 10121 is on the line segment 1015 and at a distance h from the vertex 1012, and is on the line segment 1016 and at a distance h from the vertex 1012. A point 10122 is obtained.

The point 101241 becomes the vertex 1022 of the parallel line segment component 102.

  With the same processing, the coordinates of the vertex 1023 of the parallel line segment component 102 and the vertices 1032 and 1033 of the parallel line segment component 103 can also be obtained.

  FIG. 12 shows an example of a drawing editing screen displayed on the display device 6 (FIG. 1), and an example in which the user creates a monitoring screen of the monitoring control system will be described.

  The user edits the arrangement and deformation of parts on the drawing editing screen 121 displayed on the display device 6. The drawing editing screen 121 includes a component inserting unit 122 for inserting a component, a sheet 123 capable of editing a drawing, an editing designating unit 124 capable of specifying editing contents for the component, an editing mode in which editing can be performed, and a browsing incapable of editing. Mode switching means 125 for switching between modes.

  The edit designation unit 124 includes a multi-line component generation unit 1241 that generates a multi-line component from line segment components, an individual part unit 1242 that disassembles the multi-line component into individual components, and a core line display that displays the core wire of the multi-line component. Means 1243, and double-lined parts 1244 for making a plurality of line segment parts into double-line parts.

  The drawing editing operation by the user will be described using the drawing editing screen 121 described above.

  First, the user operates the mode switching means 125 to shift the drawing editing apparatus 100 to the editing mode so that the drawing can be edited. This corresponds to the process of step ST101 described with reference to FIG.

  Next, the user inputs a part using the part insertion means 122. Here, as shown in FIG. 12, it is assumed that components 126, 127, and 128 have been input. In this case, step ST102, step ST103, step ST109, and step ST110 described with reference to FIG. 4 are executed inside the drawing editing apparatus 100.

  Next, the user edits the part using the editing designation means 124 (FIG. 12) or the like that can designate editing contents for the part via the input device 5 (FIG. 1) such as a mouse or a keyboard.

  After the user selects one line segment component, if the number of lines to be double-lined is specified for the line segment component using the double-line component generation unit 1241 (FIG. 12), the specified number of multi-line components are formed. The part is displayed. This operation will be described with reference to FIG.

  FIG. 13 (a) shows a line segment component 131 selected by the user. If the number of lines to be doubled is three and the double line component generation means 1241 is used, A double-tracked part 132 as shown in part (b) is displayed on the drawing editing screen 121 (FIG. 12). A double-tracked part 132 shown in FIG. 13B includes line segment parts 131, 1321, and 1322. In this case, step ST102 to step ST104 and step ST110 described with reference to FIG. 4 are executed inside the drawing editing apparatus 100.

  When the user selects the double-tracked part and then uses the individual partizing means 1242 (FIG. 12), the double-tracked part is disassembled into individual parts. This operation will be described with reference to FIG.

  FIG. 14 (a) shows the double-track component 141 selected by the user. On the other hand, when the individual component converting means 1242 (FIG. 12) is used, it is shown in FIG. 14 (b). 14 is disassembled into individual line segment parts 142, 143 and 144, and each line segment part 142 is separated from each other as shown in FIG. 14 (c). Can be edited independently. In this case, step ST102, step ST103, step ST105, and step ST110 described with reference to FIG. 4 are executed inside the drawing editing apparatus 100.

  If the user uses the core wire display means 1243 (FIG. 12) after selecting the multi-track component, the core wire of the selected multi-track component is displayed. This operation will be described with reference to FIG.

  In FIG. 15 (a), the multi-wire component 151 selected by the user is shown. By using the core wire display means 1243 (FIG. 12), the core wire 152 of the multi-wire component 151 is displayed. Is done. In this case, step ST102, step ST103, step ST107, and step ST110 described with reference to FIG. 4 are executed inside the drawing editing apparatus 100.

  Subsequently, when the user deforms the core wire 152 in the direction of the arrow AR shown in part (b) of FIG. 15 by dragging the mouse or the like, the line segment components 1511, 1512, and 1513 constituting the double-track component 151 are displayed. In addition, the deformation state is reflected, and the line segment parts 1511 to 1513 can be deformed collectively as shown in FIG. 15C. In this case, step ST102, step ST103, step ST108, and step ST110 described with reference to FIG. 4 are executed inside the drawing editing apparatus 100.

  If the user selects a plurality of line segment parts and then uses the double line parts 1244 (FIG. 12), these parts can be handled as double line parts. This operation will be described with reference to FIG.

  In FIG. 16A, three line segment parts 161, 162 and 163 selected by the user are shown. If the double-tracking part 1244 (FIG. 12) is used for these, these can be handled as one double-tracking part, and as shown in FIG. 121 (FIG. 12). In the example of part (b) of FIG. 16, among the selected line segment components 161, 162 and 163, the line segment component 162 closest to the center of the screen is used as the reference line segment component. As shown in part (c) of FIG. 16, among the selected line segment components 161, 162, and 163, the line segment component 163 farthest from the center of the screen may be used as the reference line segment component. The reference line segment component may be arbitrarily designated by the user. In this case, step ST102, step ST103, step ST106, and step ST110 described with reference to FIG. 4 are executed inside the drawing editing apparatus 100.

  When the desired editing by the user is completed, the editing mode is terminated using the mode switching means 125 (FIG. 12). Until the editing mode ends, the processes in steps ST102 to ST110 are repeated in the drawing editing apparatus 100.

<Effect>
As described above, by using a multi-line component, it is possible to edit a parallel line segment component simply by editing the reference line segment component, and the user can edit all the line segment components parallel to each other. On the other hand, since it is not necessary to perform the same editing, the editing work is reduced.

  In other words, conventionally, since the processing of editing the shape of a graphic composed of point sequences such as polygonal lines and polygons was performed for each graphic, when editing a plurality of parallel line segment components, Editing work for those numbers was necessary. However, by using the drawing editing apparatus 100 according to the first embodiment, when there are a plurality of line segment parts parallel to each other, they can be bundled as a multi-line part, and one of them can be combined. Editing operations can be performed on the line segment components, and editing can be performed with less effort.

  In addition, since the multi-track parts can be edited and then disassembled into individual parts, they can be edited together and edited as individual parts, and the user can execute a desired editing operation without restriction.

<Embodiment 2>
In the drawing editing apparatus according to the second embodiment, the display method of the corners formed by the adjacent line segments of the line segment components constituting the double line component is selectable. More specifically, for each bent portion of the line segment component, it is possible to select whether to display as a corner or an arc.

<Device configuration>
FIG. 17 is a block diagram showing a configuration of a drawing editing apparatus 200 according to the second embodiment realized by the computer system shown in FIG. Note that the same components as those of the drawing editing apparatus 200 shown in FIG.

  In the drawing editing apparatus 200 shown in FIG. 17, the double-tracked component editing unit 232 includes a double-tracked component corner deformation unit 2326. In addition to the coordinates of the parallel line segment parts, the double line part coordinate calculation unit 2325 uses the coordinates of the reference line segment parts, the center coordinates, the radius, and the line segments of the concentric circles at the corners of the double line components. The contact coordinates with the row parts can be obtained.

  In addition to the component information, the component information storage unit 24 calculates the center coordinates, the radius, and the contact coordinates with the line segment components of the concentric circles at the corners of the double-tracked component calculated by the double-tracked component coordinate calculation unit 2325. It is configured to store information.

  Also, the double-track control part information storage unit 25 displays, in addition to the double-track control part information, the corners formed by the line segments in the line segment components constituting the double-track parts as squares. In this configuration, corner shape information indicating whether or not to display an arc is stored.

  In addition, the double-tracked part corner deforming unit 2326 acquires and updates the corner shape information of the double-tracked control part, and obtains information such as the coordinates of the double-tracked part that matches the corner shape information from the part information storage unit 24. get. If there is no information that matches the corner shape information in the component information storage unit 24, the information calculated by the multi-line component coordinate calculation unit 2325 is acquired and stored in the component information storage unit 24. Thereafter, the information on the double-tracked parts is transferred to the display unit 21.

  Note that the double-track component corner deformation unit 2326 is realized by reading a software program stored in the external storage device 4 to the main storage device 3 and executing it by the central processing unit 2.

<Overall editing process>
Next, a processing procedure in the drawing editing apparatus 200 when editing a multi-track component will be described. FIG. 18 is a flowchart showing the overall flow of the multi-line component editing process.

  18, step ST201, step ST202, step ST204, step ST205, step ST206, step ST207, step ST208, and step ST209 are respectively step ST101, step ST102, step ST209 in the drawing editing apparatus 100 shown in FIG. Processing similar to ST104, step ST105, step ST106, step ST107, step ST108, and step ST109 is performed.

  When an event occurs, the user input receiving unit 22 determines the event (step ST203). Here, Table 2 shows a list of events that occur during component selection.

  In Table 2, “-” indicates an invalid event or an event that cannot occur. The event that has occurred is determined by the type of the part being selected and the conditions at the time of the event occurrence. The difference from Table 1 is that a “double-line part corner deformation” event is added.

  Table 2 shows conditions when a mouse is used as the input device 5 and a menu such as “Generate double-tracked parts” is in the pull-down menu displayed from the menu bar of the drawing editing device. Yes. For example, if the position clicked with the left mouse button is “Generate double-line component” in the pull-down menu displayed from the menu bar of the drawing editing apparatus, a “Double-line component generation” event occurs. If the position clicked with the right mouse button is the vertex of the core line displayed on the double-tracked component, a “double-tracked component corner deformation” event occurs.

  In Table 2, an event is generated by the mouse, and the mouse events are classified into “click the left button”, “click the right button”, “start dragging with the left button”, and “others”.

  In addition, examples of events include “double-tracked part generation”, “vertex display”, “double-tracked part creation”, “core line display”, “individual partization”, “double-tracked part transformation”, “double-tracked part corner” “Deformation” and “Normal processing”.

  In Table 2, the relationship between the selection target part and the validity / invalidity of the event is almost the same as in Table 1. “Double line part deformation” and “Double line part corner deformation” are effective events.

  Here, returning to the description of FIG. 18, if the input event is a “double-line part corner deformation” event as a result of the event determination in the user input reception unit 22, the double-line part corner deformation process (step If the event is other event, the same operation as the drawing editing apparatus 200 of the first embodiment is performed.

  After executing any of the processes in steps ST204 to 209 and step ST211, the display unit 21 displays each component edited in steps ST204 to 209 and step ST211 on the display device 6 in step ST210. After step ST210, the process returns to the event waiting state of step ST202.

  In this way, the processing from step ST202 to step ST211 is repeated until the edit mode is set to OFF.

  It should be noted that the double-track component generation processing in step ST204, the individual component processing in step ST205, the double-track component conversion processing in step ST206, and the double-track component deformation processing in step ST208 are the same as step ST104 (first step described in the first embodiment). 5), ST105 (FIG. 6), ST106 (FIG. 7), and ST108 (FIG. 8), except for the multi-line component coordinate calculation process (ST1046, ST1064, ST1083) in steps ST104, ST106, and ST108. It is.

<Double-track component coordinate calculation processing>
Hereinafter, the multi-line component coordinate calculation process in the multi-line component coordinate calculation unit 2325 in the drawing editing apparatus 200 according to the second embodiment will be described with reference to the flowchart shown in FIG.

  In FIG. 19, step ST12 of the flowchart of FIG. 9 in the first embodiment is replaced with step ST121, and the other processing contents are the same as those in FIG.

  In step ST121, similarly to step ST12 (FIG. 9), the multi-line component coordinate calculation unit 2325 uses the coordinates of the reference line segment component and the coordinates of the end points obtained in step ST11 to end the parallel line segment component. Calculate the coordinates of points other than. However, the difference is that the coordinates calculated when obtaining points other than the ends of the parallel line segment parts are stored in the part information storage unit 24.

  For example, the point 10123 shown in part (f) of FIG. 10 is stored as the center coordinates of the concentric circles at the corners formed by the line segments 1015 and 1016. Further, the point 10121 shown in FIG. 10E is stored as a concentric contact point in the line segment 1015, and the point 10122 is stored as a concentric contact point in the line segment 1016. Further, the following procedure is added to the procedure described in the (d) part, (e) part, (f) part, and (g) part of FIG. 10, and the radius of the concentric circle is stored. That is, the distance between the points 10121 and 10123 shown in the (e) part of FIG. 10 is obtained and set as the radius of the concentric circle.

<Double line part corner deformation processing>
Next, details of the double-tracked component corner deformation process in step ST211 shown in FIG. 18 will be described using the flowchart shown in FIG.

  In the double track component corner deformation process, first, the double track component corner deforming unit 2326 acquires the double track control component of the selected double track component from the double track control component information storage unit 25 (step ST2111). .

  Next, the double-tracked component corner deforming unit 2326 acquires the vertex information specified by the input device 5 from the user input receiving unit 22. Using the acquired vertex information, the corner shape information of the vertex is acquired from the double-tracking control component acquired in step ST2111 (step ST2112). Here, the corner shape information is included in the double-tracking control component, and is information indicating whether the corner portion is displayed as a square or an arc, and is set to be a square or an arc as a default setting. Yes. Even if it is set to either by default, there is no problem because the user who sees it can change it arbitrarily.

  Next, the double-tracked part corner deforming unit 2326 updates the corner shape information of the designated vertex (step ST2113). That is, if the information acquired in step ST2112 is “display with squares”, the information is updated to “display with arcs” and the information in the double-track control part information storage unit 25 is updated. If the information acquired in step ST2112 is “display with arcs”, the information is updated to “display with squares” and the information in the double-track control part information storage unit 25 is updated.

  Next, the double-tracked part corner deforming unit 2326 acquires information such as the coordinates of the double-tracked part from the part information storage unit 24 (step ST2114).

  Next, the double-track component corner deforming unit 2326 determines the corner shape from the updated corner shape information (step ST2115). If the determined corner shape is “square”, the process proceeds to step ST21110, and if it is “arc”, the process proceeds to step ST2116.

  In step ST2116, the multi-line part corner deforming unit 2326 determines whether or not the information acquired in step ST2114 includes arc information such as the center coordinates, radius, and contact coordinates of the concentric circles of the designated corners. To do. If the arc information is “present”, the process proceeds to step ST2119. On the other hand, if there is no arc information, the process proceeds to step ST2117.

  The multi-line component coordinate calculation process in step ST2117 is the same as the process described with reference to FIG. 19 and is a process for calculating the coordinates of points other than the ends of the parallel line segment parts. Arc information such as the center coordinates of the concentric circles, the contact coordinates of the concentric circles, and the radius of the concentric circles.

  Next, the double track part corner deforming unit 2326 stores the arc information calculated in step ST2117 in the part information storing unit 24 (step ST2118).

  Next, the double-tracked part corner deforming unit 2326 passes the coordinates of the double-tracked part acquired in step ST2114 and the arc information calculated in step ST2117 to the display unit 21 (step ST2119).

  In addition, the double-tracked part corner deforming unit 2326 passes the coordinates of the double-tracked part acquired in step ST2114 to the display unit 21 (step ST21110). In this case, the arc information of the designated corner is not passed.

<Drawing editing operation>
Next, a drawing editing operation in the drawing editing apparatus 200 will be described with reference to FIGS. 21 and 22. In the following, a user operation for selecting, for each corner, whether the corner of the multi-line component is displayed as a square or an arc will be described. Other operations are the same as those in the first embodiment described with reference to FIG.

  FIG. 21 shows an example of a drawing editing screen displayed on the display device 6 (FIG. 1), and an example in which the user creates a monitoring screen of the monitoring control system will be described.

  The drawing editing screen 121A shown in FIG. 21 is different from the drawing editing screen 121 shown in FIG. 12 in that the editing designation unit 124 includes a corner shape switching unit 1245 that switches the shape of the corner.

  For example, when the corner shape switching unit 1245 of the editing designation unit 124 is selected, the corner shape switching unit 1245 can switch the shape of the corner of the selected vertex in the multi-line component. Further, the corner shape switching means 1245 is not provided in the pull-down menu displayed from the menu bar of the drawing editing apparatus, but as a means for right-clicking with the mouse on the vertex of the double-lined part whose corner shape is to be switched. Also good.

  Next, after the user selects a double-tracked part, an operation for performing a double-tracked part corner deformation process on the double-tracked part will be described with reference to FIG.

  FIG. 22 (a) shows the double-tracked component 2101 selected by the user. When the core wire display means 1243 is used for this double-tracked component 2101, it is shown in FIG. 21 (a). Thus, the core wire 2102 is displayed. In this case, step ST202, step ST203, step ST207, and step ST210 described with reference to FIG. 18 are executed inside the drawing editing apparatus 200.

  Next, when the user uses the corner shape switching unit 1245 on the vertex at which the corner is desired to be rounded, the corner is rounded and displayed as shown in part (b) of FIG. That is, when the right click operation of the mouse is performed on the vertex 21021, as shown in the part (b) of FIG. On the other hand, when the corner shape switching means 1245 is used on the apex of the rounded corner (when a mouse right-click operation is performed), the shape shown in FIG. 22A can be restored. In this case, step ST202, step ST203, step ST211 and step ST210 described with reference to FIG. 18 are executed inside the drawing editing apparatus 200.

<Effect>
As described above, the drawing editing apparatus 200 according to Embodiment 2 can display the shape of an arbitrary corner of the double-tracked component as a corner or an arc.
