Description

  The present invention relates to a drawing editing apparatus that edits drawings, and more particularly to a drawing editing apparatus that edits a plurality of drawings at once.

  In the work of creating drawings such as design, etc., improvements will be made while revising the drawings once created. Depending on the product to be designed, a derivative drawing is created from one type of drawing and is often managed as a drawing of a similar product. If design deficiencies are detected in such design work, similar deficiencies can be considered for other products based on the original drawing or derived drawing. There is a problem that a large number of man-hours are required.

As a method for automatically changing and managing a plurality of related drawings in order to solve the above problems, there is a technique disclosed in Patent Document 1. The technique shown in Patent Document 1 is a design drawing management method that automatically identifies the relationship between drawings and automatically changes the drawing number, history, etc. of all drawings related to the changed drawing. Assign attributes to the drawing number, drawing name, top-level drawing, subordinate drawing, etc. of the drawing, and read the drawing number, drawing name, top-level drawing, subordinate drawing, etc. data from the above design drawing based on that attribute A drawing configuration table representing the hierarchical relationship of these design drawings is automatically created. When the design drawing a is changed to a ′, all the design drawings related to the design drawing a before being changed are automatically detected based on the drawing configuration table, and the detected design drawing is changed. It is automatically changed based on the designed drawing a ′.

  However, the technique shown in Patent Document 1 has a parent-child relationship with drawings, and when a child drawing is changed, a plurality of parent drawings including the child drawing can be collectively changed. If it is changed, all of the parent drawings are changed in common. Therefore, it is necessary to separate the parent drawing whose child drawing is to be changed from the parent drawing which is not so, and there is a problem that the management becomes complicated in return.

  Accordingly, the present invention has been made to solve the above-described problems, and provides a drawing editing apparatus, a drawing editing method, and a drawing editing program that collectively edit common portions in a plurality of CAD data. Objective.

Since the editing information is reflected in the data, the editing work can be performed collectively on a plurality of CAD data, and the working efficiency can be improved.
In addition, since an arbitrary number of CAD data to be edited is selected and the editing information is reflected only on the selected CAD data, the CAD data to be edited can be selected, and the CAD data management configuration, etc. There is an effect that editing work can be performed freely without worrying about.

  Even if the selected CAD data does not include a common element, it is possible to group CAD data including a common element among a plurality of groups and perform editing work for each group. be able to.

(2. Edit common elements)
In the drawing editing apparatus, the CAD data editing means controls to edit only the common elements extracted by the common element extraction means.
In this way, in the drawing editing apparatus, since only the common elements extracted by the common element extraction unit are controlled to be editable, it is easy for the operator to perform editing processing, and work efficiency can be improved. There is an effect.

(3. Coordinate correction)
In the drawing editing apparatus, the synthesizing unit matches the coordinates indicating the position of each element in the CAD data selected by the CAD data selecting unit with the coordinates indicating the position of each element in any one CAD data. It is provided with the correction means which correct | amends.
As described above, in this drawing editing apparatus, the coordinates indicating the position of each element in the CAD data selected by the CAD data selection means are made to coincide with the coordinates indicating the position of each element in any one CAD data. Therefore, it is possible to prevent a situation in which a common element cannot be recognized and a drawing cannot be synthesized because the entire drawing is shifted even though there are common elements. There is an effect.

(4. Extracting common editable elements)
In the drawing editing apparatus, the common element extraction unit extracts elements that can be edited in common with all or a plurality of arbitrary CAD data selected by the CAD data selection unit.
In this way, in the drawing editing apparatus, the common element extraction unit extracts elements that can be edited in common with all or a plurality of selected CAD data, so that elements that cannot be edited in common ( For example, elements that are common as elements but differ only in a part of the elements) can be excluded from the batch editing target, and the work efficiency of the operator can be improved. On the other hand, if the elements can be edited in common even if their element sizes and coordinates are slightly shifted, they can be extracted and used as a batch editing target, and the work efficiency can be further improved. .

(First embodiment of the present invention)
(1. Configuration and function)
(1-1 Hardware configuration)
FIG. 1 is a hardware configuration diagram of a drawing editing apparatus according to the present embodiment. The drawing editing apparatus 100 includes a CPU (Central Processing Unit) 101, a RAM (Random Access Memory) 102, a ROM (Read Only Memory) 103, a flash memory (Flash memory) 104, an external storage device HD (Hard disk) 105, A LAN (Local Area Network) card 106, a mouse 107, a keyboard 108, a video card 109, a display 109a that is a display device electrically connected to the video card 109, a sound card 110, and an electrical connection to the sound card 110. It comprises a speaker 110a, which is a sound output device, and a drive 111 for reading and writing storage media such as a flexible disk, CD-ROM, DVD-ROM and the like.
Note that the above hardware configuration is merely an example, and it is natural that the components can be changed.

(1-2 Module configuration and functions)
FIG. 2 is a module configuration diagram of the drawing editing apparatus according to the present embodiment. The drawing editing apparatus 100 includes a CAD data selection processing unit 210, a common element extraction processing unit 220, a CAD data synthesis processing unit 230, a CAD data editing processing unit 240, an editing information reflection processing unit 250, and CAD data 260. Is provided.

  The CAD data selection processing unit 210 performs processing for selecting CAD data to be edited from the CAD data 260 based on an instruction from the worker 201. At this time, the operator arbitrarily determines CAD data to be edited.

  The common element extraction processing unit 220 performs processing for extracting common elements from the CAD data selected by the CAD data selection processing unit 210. At this time, elements common to all CAD data are extracted, and elements common to a plurality of arbitrary CAD data are extracted together.

  The CAD data synthesis processing unit 230 performs processing for integrating the common elements extracted by the common element extraction processing unit 220 and synthesizing the CAD data selected by the CAD data selection processing unit 210. At this time, the drawings are synthesized so that common elements and other elements can be distinguished. For example, an element common to all CAD data is a black solid line, an element common to any plurality of CAD data is a black dotted line, a non-common element is distinguished as a red solid line, or a common CAD You may distinguish by setting the thickness of a line according to the number of data. Further, common elements may be distinguished by solid lines, and other elements may be distinguished by dotted lines.

The CAD data editing processing unit 240 performs processing for editing the CAD data synthesized by the CAD data synthesis processing unit 230 based on an instruction from the worker 201. Here, only the common elements extracted by the common element extraction processing unit 220 (elements common to all CAD data and elements common to a plurality of CAD data) are edited.
Note that elements other than the common elements may be edited.

The editing information reflection processing unit 250 performs processing for reflecting the information edited by the CAD data editing processing unit 240 on each CAD data. That is, the editing information performed on the common element of the data synthesized by the CAD data synthesis processing unit 230 is reflected on each CAD data that is the source of the synthesis.
The CAD data 260 is a database that stores a plurality of CAD data.

(2. Operation)
(2-1 Processing Operation of Entire Device)
FIG. 3 is a flowchart showing the operation of the drawing editing apparatus according to the present embodiment. First, an instruction of CAD data to be edited is input from the operator (step S301). Based on an instruction from the operator, CAD data to be edited is selected from the external storage unit and stored in the internal storage unit together with the CAD data list (step S302).

  Here, the target CAD data will be described. FIG. 4 is a diagram illustrating an example of a process of generating target CAD data. In this case, it is assumed that the CAD data of FIGS. 4B, 4C, 4D, and 4E is derived from the CAD data of the automobile as the basis of FIG. The element that coincides in common with all the CAD data is the vehicle body lower portion 410, and the element that coincides in common with the CAD data of (a), (b), (c) and (d) is the tire 420. The element that coincides in common with (d) and (e) is the vehicle body upper portion 430. As described above, data having common elements is selected as CAD data to be edited.

  As shown in FIG. 4, it is desirable to select CAD data that is derived from basic CAD data, but if it is not, CAD data that seems to have common elements may be selected. You can choose anything.

  Returning to FIG. 3, a synthesis process for synthesizing the selected CAD data is performed (step S303), and the synthesized CAD data is stored in the internal memory. The synthesized CAD data is edited by the operator's CAD operation (step S304), and it is determined whether or not the edited information is to be saved (step S305). If not saved, the process is terminated. In the case of saving, a reflection process for reflecting the edited data in each CAD data is performed (step S306), and the process ends.

  Here, processing from synthesis to reflection of CAD data will be described. FIG. 5 is a diagram illustrating an example of processing for combining CAD data and reflecting editing contents. Here, it is assumed that the five CAD data shown in FIG. 4 are selected for editing. The result of combining these five drawings is the integrated diagram (1). In FIG. 1, a lower body 410 that is an element common to all five CAD data is drawn with a red solid line, and a tire 420 (( a) to (d)) and the vehicle body upper portion 430 (common to (d) and (e)) are drawn with blue solid lines, and other non-common elements are drawn with dotted lines. The integrated diagram 1 is obtained by editing the integrated diagram 1 by CAD operation. In the integrated diagram 2, the vehicle body lower portion 410 is edited so that the length in the front-rear direction is increased. In the case of saving the edited vehicle body lower portion 410 in length, a process of reflecting it in each CAD data to be edited is performed. The CAD data after reflection is (a) 'to (e)'. In this way, the length of the lower body 410 of each CAD data is edited to be the same as the length of the lower body 410 in the integrated diagram 2.

  For elements that are common to any of a plurality of CAD data other than elements common to all CAD data (elements drawn with a solid blue line in the integrated diagram 1), which CAD element is the element Information indicating whether the data is common may be displayed. As a display method, for example, it may be displayed on a part of the screen by selecting with a mouse or a keyboard, or information on common CAD data is displayed by right-clicking the mouse in the selected state. Also good.

Further, only elements common to all CAD data may be regarded as common elements, and elements drawn with a solid blue line in the integrated diagram 1 may not be regarded as common elements. In that case, the element drawn with a blue solid line is drawn with a broken line.
Further, the elements that can be edited in the integrated diagram 1 may be limited to only common elements drawn with a solid line.

(2-2 Details of processing to synthesize CAD data)
The combining process for combining the selected CAD data in step S303 in FIG. 3 will be described in detail. FIG. 6 is a flowchart showing the synthesis process. First, 1 (first element) is set to a variable N indicating an element number (step S601). The Nth element is acquired from the CAD data stored in the internal memory (step S602), and an element whose element type, coordinate, and attribute match with the Nth element is searched from elements other than the acquired Nth element. (Step S603). As a result of the search, it is determined whether there is a matching element (step S604). If there is no matching element, it is not an element common to a plurality of CAD data, and is added to the synthesized CAD data (step S605). The elements added here are the elements indicated by the broken lines in the integrated diagram of FIG. When there is a matching element or when the process of step S605 is completed, the CAD data ID, name, and element ID are added to the element information (step S606). It is determined whether or not processing has been completed for all elements (step S607). If processing has not been completed for all elements, 1 is added to N (step S608), and the process returns to step S602, and the next Process the element. If processing has been completed for all elements, it is determined whether processing has been completed for all selected CAD data (step S609), and processing has not been completed for all selected CAD data. Returning to step S302 of FIG. 3, processing is performed on the next CAD data. If the processing has been completed for all the selected CAD data, a common flag is set for the elements to which all or a plurality of CAD data IDs have been added (step S610), and the processing ends.

  Here, the synthesis process will be described in more detail. FIG. 7 is a diagram showing an example of the contents of CAD data in the synthesis process. Here, it is assumed that (a) is revised and (b) is created, and (c) is derived from (b). The data indicating the drawing of (a) is data (a) ′, the data indicating the drawing of (b) is data (b) ′, and the data indicating the drawing of (c) is data (c) ′. . Each data has an ID for uniquely determining an element, and is represented by attribute values such as type, coordinates, line color, line type and the like. In the synthesis, first, the CAD data to be edited is selected from the drawing management system such as a CAD system or a PDM system (Product Data Management System) based on the instructions of the operator (a) to (c). The

  FIG. 6A is a diagram obtained by combining and synthesizing (a) to (c) according to the processing of FIG. 6, and data obtained by integrating data (a) ′ to data (c) ′ is data (d) ′. It is. First, data (a) 'is read by a CAD system and recorded on a memory. At this time, an ID for each element is newly assigned, and a base diagram and an element ID in the base diagram are held for each element. Next, the data (b) 'is read and compared with the graphic element stored in the memory for each element, and an element having the same type, coordinate, and attribute is searched. For example, a straight line with coordinates X = 10.0, coordinates Y = 20.0, attribute 1 = solid line, attribute 2 = white corresponds to the element with ID = 21 in the data (b) ′. When the corresponding element is detected, the fact that ID = 21 of the data (b) 'is the element is recorded on the memory. If the corresponding element is not detected, it is added to the memory as a new graphic element. Similarly, when data (c) 'is processed, data (d)' can be obtained. In this case, since the element with ID = 101 and the element with ID = 104 are elements common to all the drawings (a) to (c), a flag for identifying the complete match is set.

(2-3 Details of editing processing of synthesized CAD data)
The process of editing CAD data synthesized by CAD operation in step S304 in FIG. 3 will be described in detail. FIG. 8 is a diagram showing an example of the contents of CAD data when the synthesized CAD data is edited. FIG. 8 shows the result when the position (coordinates) and color are changed for the element with ID = 102. The CAD data list table shows a list of selected drawings. The CAD operation is performed on the element to be edited by the operator. In the CAD operation, control may be performed so that only completely matched elements can be edited. In addition, each time an editing operation is performed, the presence or absence of editing is recorded in the editing target element.

  In addition, when modifying a drawing, an element to be added is often associated with an existing element. Therefore, when performing an addition operation, the operator is instructed the related element, and the added element is the target CAD data. The identification information may be copied. Further, when the deletion operation is performed, it disappears from the screen, but the element information of the CAD data may not actually be deleted, but may be left on the memory as the deletion element information. By doing so, the reflection process can be performed accurately.

(2-4 Details of processing for reflecting edited composite CAD data in each CAD data)
The reflection process of reflecting the edited combined CAD data in each CAD data in step S306 in FIG. 3 will be described in detail. FIG. 9 is a flowchart showing the reflection process. First, based on the CAD data list information stored in the internal storage unit, the CAD data to be reflected is read from the CAD data stored in the external storage unit (step S901). Information on the element to be changed is acquired based on the change presence / absence of the combined CAD data (step S902), and the ID, name, and element ID of the CAD data added to the element are acquired (step S903). It is determined whether or not the CAD data IDs match (step S904). If they match, the coordinates and attributes of the element matching the element ID are changed (or added or deleted) (step S905), and the update CAD Data is generated and the process proceeds to step S906. If they do not match, the process proceeds directly to step S906. It is determined whether or not the confirmation process has been completed for all elements (step S906). If all elements have not been completed, the process returns to step S902 to process the next element. If all the elements have been completed, the edited CAD data is stored in the external storage unit based on the update CAD data (step S907). It is determined whether or not processing has been completed for all CAD data (step S908), and if not, processing returns to step S901 and processing is performed for the next CAD data. If completed, the process is terminated as it is.

  Here, the reflection process will be described in more detail. FIG. 10 is a diagram showing an example of the contents of CAD data in the reflection process. In FIG. 8, the result when the position (coordinates) and the color are changed for the element of ID = 102 of the data (d) 'is reflected in each CAD data. First, the CAD data (a) ′ to (c) ′ that are the basis for integration are read, the changed element (ID = 102) is searched from the synthesized CAD data (d) ′, and Take out the ID (name). From the extracted base diagram, it can be seen that the element ID = 12 in (a) ′ corresponds to the element ID = 102. The coordinates, attributes, and the like of the element ID = 12 of the read data (a) ′ are changed according to the value of the composite data (d) ′. Here, there are no other edited elements, but when other elements are edited, the matching elements are similarly searched and changed. After all the elements have been changed, the data (a) 'is saved. Similarly, data (b) 'and data (c)' are processed.

In FIG. 10, the CAD data to be reflected because the element with ID = 102 is edited is data (a) ′ and data (c) ′, but editing is performed for ID = 104, which is an element common to all CAD data. If it is done, the editing is naturally reflected in the data (b) ′.
Further, when data is stored, it may be possible to select whether to update previous data or whether to add another data name for storage.
Further, it is desirable that the selected CAD data is subjected to an exclusive process so that other persons cannot edit until the reflection process is completed.

  As described above, in the drawing editing apparatus according to this embodiment, an arbitrary number of CAD data to be edited is selected, the selected CAD data is synthesized, and editing processing is performed on the synthesized CAD data. Since the editing is reflected in each CAD data, the editing work can be performed on a plurality of CAD data at a time, and the work efficiency can be improved. In addition, since any number of CAD data to be edited is selected and the editing information is reflected only in the selected CAD data, the CAD data to be edited can be selected, and the configuration of the CAD data can be changed. You can freely edit without worrying. Furthermore, if only the common elements extracted by the common element extraction processing unit 220 are controlled to be editable, the operator can easily perform the editing process, and the work efficiency can be further improved.

(Second embodiment of the present invention)
Hereinafter, the drawing editing apparatus according to the present embodiment will be described, but the description of the overlapping parts with the first embodiment will be omitted, and only different parts will be described.
(1. Configuration and function)
(1-1 Module configuration and functions)
FIG. 11 is a module configuration diagram of the drawing editing apparatus according to the present embodiment. The difference from the first embodiment is that a coordinate correction processing unit 1110 is provided.
The coordinate correction processing unit 1110 performs processing for correcting the coordinates of the CAD data. For example, when CAD data having a common element at first glance is selected but there is no common element, the coordinates may be shifted as a whole. In such a case, the CAD data are compared to unify the coordinate system.

(2. Operation)
FIG. 12 is a flowchart showing the synthesis process according to the present embodiment. Since the processing from step S601 to step S608 is the same as that of the first embodiment, description thereof is omitted. When the process is completed for all elements in step S607, it is determined whether there is a common element (step S608a). If there is no common element, a coordinate correction process is performed (step S608b), and the process of step S601 is performed. Return to. If there is a common element, the process proceeds to step S609. Since the processing after step S609 is the same as that of the first embodiment, description thereof is omitted.

Here, the coordinate correction processing in step S608b will be described in detail. FIG. 13 is a flowchart of the coordinate correction process. First, an arbitrary element (denoted as element a) in CAD data (denoted as data A) is extracted (step S1301), and the type and size of the extracted element are set as other CAD data (denoted as data B). Are compared with all the elements (step S1302). As a result of the comparison, it is determined whether there is a matching element (element b) (step S1303). If there is no matching element, the process returns to step S1301 to process the next element. If there is a matching element, the entire element of data A is shifted (including rotation) so that element a matches element b (step S1304). In this state, data A and data B are compared again to calculate the number of common elements (step S1305). It is determined whether or not the number of common elements is equal to or greater than a predetermined threshold (step S1306). If the number of common elements is not equal to or greater than the predetermined threshold, the process returns to step S1301 to process the next element. If the common element is equal to or greater than the predetermined threshold, the coordinate correction is completed (step S1307) and the process is terminated.
As described above, feature points (for example, the interval between element a and element b) are extracted without correcting all the elements, and the coordinates are corrected so that the feature points match. Also good.

  As described above, in the drawing editing apparatus according to the present embodiment, the coordinates indicating the position of each element in the CAD data selected by the CAD data selection processing unit 210 are used, and the position of each element in any one CAD data is used. Since the correction is performed so as to match the coordinates shown, it is possible to prevent a situation in which the common elements cannot be recognized and the drawings cannot be synthesized because the entire drawing is shifted.

(Other embodiments)
(1. Application to circuit diagram)
The present invention can be applied to circuit diagrams. FIG. 14 is a diagram showing processing when the circuit diagrams are collectively edited. The circuit diagram (d) is obtained by integrating the circuit diagrams (a), (b), and (c). Although the circuit diagrams (a), (b), and (c) appear to be different circuits at first glance, the only different part is actually the dotted line shown in (d). By editing the common part of the circuit diagram (d), it can be reflected in each circuit diagram (a), (b), (c), and the processing can be made efficient. In this case, the element in each of the above embodiments is a contact in the circuit diagram of FIG. 14, and can be realized by holding the connection destination of each contact as data as a type or attribute. Since the technology for constructing a circuit diagram from the contacts is an existing technology, description thereof is omitted.
The specific process is to select a circuit diagram to be edited, create a composite image that integrates each circuit diagram based on connection information at the contacts of the selected circuit diagram, edit each composite circuit, and then edit each circuit. The edit information is reflected in the figure.

(2. Commonization)
The present invention can also integrate different elements in common. For example, the elements indicated by dotted lines in the integrated diagram (1) in FIG. 5 are not common elements, but a reference element (or an average element) between different elements is determined as a master element, and the master element By editing the elements, it is possible to share other non-common elements. Also, CAD data to be shared can be selectively extracted. For example, in FIGS. 5A and 5C, when it is desired to match the upper body 430 with (d) for (a) and (c), but not for (b), only (a) and (c) are shared. can do. At this time, the common element may be shared based on an instruction from the operator, or the common element extraction processing unit 220 may extract only elements whose coordinate deviation is within a predetermined range (elements that can be edited collectively). Also good.

(3. Error during integration)
Furthermore, in the second embodiment, the process for correcting the coordinates has been described. However, if the deviation of the element position is within the error range, it is determined that the element is a common element, and the subsequent processes are performed for each element. It is also possible to perform integration processing while correcting based on the offset value.
As described above, since the drawing editing apparatus according to the present embodiment can be applied to a circuit diagram, processing is efficiently performed when a complicated circuit (for example, a wire harness of an automobile) is edited. be able to. Further, for example, in a design drawing in which different designs are made by different designers, when it is desired to share different elements, it is possible to make the processing more efficient because they can be shared in a lump. . Furthermore, even if the coordinates of the elements are slightly shifted, the CAD data is synthesized while correcting as the error range, so that the processing can be made efficient.

  Although the present invention has been described with the above embodiments, the technical scope of the present invention is not limited to the scope described in the embodiments, and various modifications or improvements can be added to these embodiments. . And embodiment which added such a change or improvement is also contained in the technical scope of the present invention. This is apparent from the claims and the means for solving the problems.
