The display data generation unit 25 performs a display data generation operation based on information in the display information storage unit DB3.

  The display condition receiving unit 26 receives display conditions when the display data generating unit 25 generates display data. For example, the display condition receiving unit 26 receives designation of display conditions from the user by operating the information terminal 1 via the communication unit 29.

  For example, the display condition accepting unit 26 accepts designation of a specific item (selection designation) and designation of an observation direction of a specific item group, and supplies them to the display data generation unit 25. For example, when the display condition reception unit 26 receives designation of the observation direction of the item group, the item model unit 25a of the display data generation unit 25 represents the appearance, specification information, and relative position of each item for the designated observation direction. Display data including a two-dimensional display is generated.

One of an individual observation direction and an overall observation direction that is a specific observation direction for the item group is defined. Specifically, in the present embodiment, the observation direction defining unit 27 defines the observation direction of the entire item group as the overall observation direction from the acquired three-dimensional data, and at least one for each item as the individual observation direction. Two observation directions are defined.

  The overall observation direction or the individual observation direction defined by the observation direction defining unit 27 is supplied to the display data generating unit 25. That is, the display data generation unit 25 generates display data including a two-dimensional display representing the appearance of the item group and the specification information of each item for the entire observation direction or the individual observation direction defined by the observation direction defining unit 27.

  The display mode determination unit 28 determines the display mode of the specification information of each item based on the shape of each item and the relative position between items when the display data generated by the display data generation unit 25 is displayed. That is, the display mode determination unit 28 determines the display mode of the specification information of each item in the two-dimensional display of the item group based on the appearance of each item in one observation direction, the relative position between items, and the relative attitude. .

  In the present embodiment, the display mode determination unit 28 determines the display position or display orientation of the specification information of each item at the time of two-dimensional display of the two-dimensional data generated by the display data generation unit 25.

  Specifically, the item model unit 25a of the display data generation unit 25 includes an item group (the observation direction specified by the observation direction definition unit 27 or the observation direction specified by the user and received by the display condition reception unit 26 ( Display data including a two-dimensional display representing the appearance, specification information, relative position, and relative attitude of each item is generated.

  In the present embodiment, the display data generated by the display data generation unit 25 is supplied to the display mode determination unit 28. The display mode determination unit 28 determines the display state of the specification information in the two-dimensional display of the display data, for example, moves the display position and changes the display posture. In the present embodiment, display data including the display mode of the specification information determined by the display mode determining unit 28 is transmitted to the information terminal 1 via the communication unit 29 and output (displayed) to the output unit 12 of the information terminal 1. Is done.

  In addition, the display mode determination unit 28 displays various modes for displaying the specification information such as the display size, display color, and font in addition to the display position and display orientation (direction and angle thereof) of each specification information. decide. In the present embodiment, information related to the display size, display color, font, and the like is stored in the display information storage unit DB3, and the display mode determination unit 28 reads the information in the display information storage unit DB3, Determine (select) the display size of each specification information.

  In this embodiment, the display mode determination unit 28 displays the display data on the information terminal 1 when or after the display data generation unit 25 generates the display data (that is, before the display data is displayed on the information terminal 1). After the data is transmitted (that is, displayed on the information terminal 1), a decision is made to omit the specification information of at least one item. That is, in the present embodiment, the display mode determination unit 28 performs selection (determination) in which at least one specification information of at least one item is not displayed in the two-dimensional display of display data.

  In the present embodiment, the display data generating unit 25 is for the screen for guiding the input operation of the display data for the initial screen that is output to the output unit 12 of the information terminal 1 to start the design support, and the three-dimensional data. Display data may be generated.

  Further, the display data generation unit 25 may generate display data for a screen for storing data under design in the information terminal 1 or a screen for interrupting or ending design support. In addition, for a user who has a history of design support by the design support apparatus 2, the display data generation unit 25 obtains data for which design support has been provided in the past in addition to acquisition of 3D data (new acquisition). Display data for displaying a screen to be selected may be generated.

  Thus, for example, when generating display data that does not require acquisition of three-dimensional data, the display data generated by the display data generating unit 25 is not supplied to the display mode determining unit 28, and the information terminal 1 May be sent to. In other words, the communication unit 29 transmits the display data generated by the display data generation unit 25 or the display data of the mode determined by the display mode determination unit 28 to the information terminal 1.

  Next, a detailed operation and an operation sequence of each processing unit of the design support apparatus 2 will be described with reference to FIGS. 2A, 2B, and 3 to 10. First, FIGS. 2A and 2B are flowcharts showing the flow of the design support operation of the design support apparatus 2. The design support apparatus 2 is accessed from the information terminal 1 to the design support apparatus 2 and starts a design support operation by uploading or selecting support target three-dimensional data.

  First, the three-dimensional data acquisition unit 21 acquires three-dimensional data of an item group, for example, CAD data from the information terminal 1 (FIG. 2A / STEP01). For example, the three-dimensional data transmitted from the information terminal 1 is received by the communication unit 29 of the design support apparatus 2 via the network line and supplied to the three-dimensional data acquisition unit 21.

  Specifically, when the display data generation unit 25 detects an access from the information terminal 1, the input unit of the information terminal 1 for acquiring (or selecting) a design support start screen and three-dimensional data to be supported. (Input interface) The display data which comprises 11 is produced | generated. The display data generation unit 25 transmits the generated display data to the information terminal 1 via the communication unit 29. The user operates the information terminal 1 based on the operation guide information output to the output unit 12 of the information terminal 1 and uploads three-dimensional data. Thereby, the three-dimensional data acquisition unit 21 acquires three-dimensional data.

  FIG. 3 is a diagram illustrating a display example on the information terminal 1 of the display data for obtaining guidance or selection guidance of the three-dimensional data generated by the display data generation unit 25 in STEP01 of FIG. 2A.

  As shown in FIG. 3, the display data generation unit 25 generates display data for input operation guidance that includes the three-dimensional data reception display units 12a1 to 12a3. In the present embodiment, the three-dimensional data reception display unit 12a1 is a reception display unit for newly uploading three-dimensional data. The three-dimensional data reception display units 12a2 and 12a3 are reception display units for selecting an item group that has been supported by the design support apparatus 2 in the past.

  In accordance with the input guidance screen displayed in this way, the user uploads new 3D data or selects uploaded 3D data. The three-dimensional data uploaded or selected is acquired by the three-dimensional data acquisition unit 21.

  The display data generation unit 25 does not need to generate display data for the design support start screen or the data acquisition screen described above. For example, when an application that cooperates with the design support apparatus 2 is installed in the information terminal 1, the operation guide image data may already be stored in the information terminal 1. In this case, the information terminal 1 may upload or select the three-dimensional data according to the guidance of the application.

  Next, referring to FIG. 2A, the item recognition unit 22 performs a recognition (analysis) operation for each of a plurality of items constituting the item group (FIG. 2A / STEP02). Specifically, the item recognition unit 22 compares and collates the shape data included in the acquired three-dimensional data with the shape information stored in the shape information storage unit DB1, and determines the shape of each item (hereinafter, “ Also known as “solid”. Here, the item recognition unit 22 recognizes the shape and specification information of each of the plurality of items, and the relative position and relative posture between the items.

  Subsequently, the display data generation unit 25 generates display data including a two-dimensional display of the item group model (FIG. 2A / STEP03). Specifically, the item model unit 25a of the display data generation unit 25 creates a 3D model of the item group. In addition, the item model unit 25a is a 2D model (that is, the shape and specification information of each item and the relative position and relative posture between the items) when the item group is viewed from a predetermined observation direction (for example, the initial overall observation direction). Display data is generated.

  In the present embodiment, the model of the item group generated by the item model unit 25a of the display data generation unit 25 is a virtual space in which a three-dimensional coordinate axis for modeling the item group and each item is created when creating a 3D model. As defined above. And the item model part 25a creates the 3D model which shows the shape and arrangement | positioning relationship in the virtual space of an item group and each item by plotting the coordinate value read from three-dimensional data on the said virtual space.

  Next, the item model unit 25a rotates the created 3D model to project an item group corresponding to the initial observation direction and each item, for example. Then, the item model unit 25a generates two-dimensional image (display image) data indicating the item group projected from the initial observation direction (observation point). This is display data indicating the 2D model of the item group.

  Next, the display mode determination unit 28 determines the display mode of the specification information of each item based on the shape of each item in the predetermined observation direction and the relative position and relative posture between the items (FIG. 2A / STEP04). ). Here, for example, the initial observation direction of the item group when displaying the display data can be the overall observation direction defined by the observation direction defining unit 27.

  Next, it is determined whether or not display conditions for generating display data are specified (FIG. 2A / STEP 05). In the present embodiment, the design support apparatus 2 receives a display condition specification from the user by the display condition receiving unit 26. When the display condition receiving unit 26 receives the designation of the display condition, the display data generating unit 25 determines that the display condition is designated.

  When the display condition is specified, the display data generation unit 25 generates two-dimensional data under the specified display condition (FIG. 2A / STEP06). For example, when receiving the designation of the observation direction of the item group, the display condition reception unit 26 supplies information indicating the designated observation direction to the display data generation unit 25. The item model unit 25a of the display data generation unit 25 generates display data including a two-dimensional display representing the appearance of the item group and the specification information of each item for the designated observation direction.

  In addition, for example, when the display condition receiving unit 26 receives the designation of a specific item, the display data generation unit 25 is suitable for displaying the designated item (for example, the display position of the observation direction and specification information). To generate display data.

  Specifically, when a specific item is designated, the observation direction defining unit 27 supplies the display data generation unit 25 with an observation direction for displaying the specific item preferentially, that is, an individual observation direction. The display data generation unit 25 generates display data indicating the shape (appearance) of each item, the specification information, and the relative position between items when the item group in the individual observation direction is viewed.

  Here, the item model section 25a rotates the 3D coordinate axis of the 3D model defined immediately after reading the 3D data in the virtual space, and rotates the 3D model. Then, the item model unit 25a determines the position and scale of the three-dimensional coordinate axis so as to correspond to the observation direction in which the item group is observed based on the received (designated) display condition. Thereby, display data under the specified display condition is generated.

  Subsequently, the display mode determination unit 28 determines the display mode of the specification information of each item with respect to the two-dimensional data generated under the specified conditions by the display data generation unit 25 (FIG. 2A / STEP07). That is, in the present embodiment, the display mode determination unit 28 determines (re-determines) the display of specification information (for example, dimension display) in the display data when the display condition of the item group model is acquired or changed. )I do.

  For example, when the specified display condition is different from the initial display condition, the display mode determination unit 28 moves the display position of the specification information of each item, changes the display posture, or changes the display condition based on the specified display condition. Decide whether to omit the display.

  Here, when the display data is regenerated under the specified conditions, the display posture of the specification information (dimension values and symbols) displayed when viewed from the initial observation direction is rotated (tilted), and the specification information is displayed. May be unclear. The display mode determination unit 28 can change the display posture of the specification information when the display posture of the specification information is tilted by a predetermined amount or more according to the change in the observation direction. For example, when the display posture of the specification information is tilted by a predetermined angle or more, the display mode determination unit 28 determines to change (rotate) the display posture of the specification information so as to be perpendicular to the observation direction based on the specified condition. be able to.

  When it is determined in STEP 05 that the display condition is not acquired, the item model unit 25a of the display data generation unit 25 does not generate display data for model display, and the display mode determination unit 28 determines the display mode. It does not have to be done.

  Next, referring to FIG. 2B, the manufacturing condition acquisition unit 23 acquires the manufacturing conditions of the item group (FIG. 2B / STEP08). Specifically, the manufacturing condition acquisition unit 23 can select, for example, when manufacturing an item based on information in the cost information storage unit DB2 of the basic information storage unit DB or based on designation from the user. Get manufacturing conditions. For example, the manufacturing condition acquisition unit 23 acquires manufacturing conditions (material, hardness, surface treatment, etc.) necessary for manufacturing the item, its manufacturing process, manufacturing time, and the like. The manufacturing condition acquisition unit 23 may cause the user to select the acquired manufacturing condition.

  Subsequently, the cost determining unit 24 determines the manufacturing cost (for example, price and delivery date) of the item group corresponding to the acquired (selected) manufacturing condition (FIG. 2B / STEP09). Specifically, the cost determination unit 24 corresponds to the acquired or selected manufacturing condition, and determines a manufacturing cost for each item that is different for each manufacturing condition. The cost determination part 24 determines the manufacturing cost of the whole item group by determining the manufacturing cost for every item.

  Next, the display data generation unit 25 generates display data including a two-dimensional display of the manufacturing cost of the item group determined by the cost determination unit 24 (FIG. 2B / STEP 10). Specifically, the item information unit 25b of the display data generation unit 25 generates display data that represents item information including the item name, the number, and the manufacturing conditions for each item by letters, numbers, or symbols. In addition, the cost unit 25c of the display data generation unit 25 generates display data representing the manufacturing cost of the item group.

  Next, the communication unit 29 sends the display data generated by the display data generation unit 25 and the display data of the display mode generated by the display data generation unit 25 and determined by the display mode determination unit 28 to the information terminal 1. Transmit (FIG. 2B / STEP 11). Specifically, display data indicating a model of an item generated by the item model unit 25a and determined by the display mode determination unit 28, and display data including characters generated by the item character unit and the cost unit 25c are: It is transmitted to the information terminal 1.

  Subsequently, the information terminal 1 performs imaging based on the received data and displays the display data on the output unit 12 (FIG. 2B / STEP 12).

  The manufacturing condition acquisition unit 23 of the design support apparatus 2 determines whether or not the manufacturing conditions have been changed after transmitting the display data to the information terminal 1 (FIG. 2B / STEP 13). The manufacturing condition acquisition unit 23 acquires a change in manufacturing conditions by, for example, designation from the user. Here, when the manufacturing condition acquired by the manufacturing condition acquisition unit 23 is different from the designation of the manufacturing condition from the user, the manufacturing condition acquisition unit 23 determines that the manufacturing condition has been changed.

  When it is determined that the manufacturing condition has been changed, the cost determination unit 24 determines the manufacturing cost of the item group under the changed manufacturing condition (return to STEP 09). Then, the display data generation unit 25 generates display data again, and transmission to the information terminal 1 and display on the information terminal 1 are performed. On the other hand, when it is determined that the manufacturing conditions are not changed, the design support apparatus 2 ends the design support operation.

  Next, the operations of the display data generating unit 25, the display condition receiving unit 26, the observation direction defining unit 27, and the display mode determining unit 28 will be described in detail with reference to FIGS. Hereinafter, a case where the user operates the input unit 11 according to the screen shown in FIG. 3 and selects “Project 2: Ejector Tweezers B” will be described.

  FIG. 4 is a diagram illustrating a display example of the information terminal 1 in STEP 12 of FIG. 2B when the display condition designation is not acquired (for example, immediately after reading of the three-dimensional data). First, an image indicating display data generated by the display data generation unit 25 will be described. As shown in FIG. 4, the display data generated by the display data generation unit 25 is displayed on the information terminal 1 as a model display unit 12b, an item group information display unit 12c, an item information display unit 12d, and a cost display unit 12e. The

  The model display unit 12b corresponds to data generated by the item model unit 25a of the display data generation unit 25. The item group information display unit 12c and the item information display unit 12d correspond to the data generated by the item information unit 25b, and the cost display unit 12e corresponds to the data generated by the cost unit 25c.

  Next, in the example shown in FIG. 4, the ejector tweezers B is a design support target item group A composed of two ejector pins P1, one ejector pin P2, and one ejector pin P3. Each of the ejector pins P1 to P3 corresponds to the item described above. That is, ejector pins (hereinafter simply referred to as pins) P1 to P3 as a total of four items in three types constitute the item group A as a whole.

  In the present embodiment, as shown in FIG. 4, each of the pins P <b> 1 to P <b> 3 is composed of a cylindrical brim portion and a shank portion, and the lengths of the shank portions are different from each other. The pin P2 is disposed between the two pins P1, and the pins P1 and P2 are aligned in a direction perpendicular to the extending direction of the shank portion. Further, the pin P3 is disposed on the pins P1 and P2 so as to be separated from the pins P1 and P2 and to have different extension directions of the shank portions. In the present embodiment, the extension direction of the shank of the pin P3 is the same direction as the alignment direction of the pins P1 and P2.

  Next, the model display unit 12b will be described. FIG. 4 is a display example of display data indicating the shape and specification information of each of the pins P1 to P3 and the relative positions and orientations between the pins P1 to P3 when the item group A is viewed from the overall observation direction D0. Below, the specification information of the pins P1 to P3 displayed on the model display unit 12b, that is, the specification information of the pins P1 to P3 generated by the item model unit 25a will be described with respect to the dimensions of the pins P1 to P3.

  First, when the display data generation unit 25 does not acquire the designation of the display condition, the overall observation direction D0 of the item group A is set as the initial observation direction at the time of data generation, and the display data is based on the overall observation direction D0. Is generated. Therefore, the example shown in FIG. 4 corresponds to the model of the item group A when viewed (projected) from the overall observation direction D0 defined by the observation direction defining unit 27 in order to clearly display the entire item group A. .

  Note that the observation direction defining unit 27 can set the observation direction in which the overlapping portion between the pins P1 to P3 (solids) is the smallest as the overall observation direction D0, for example.

  The observation direction defining unit 27 may weight the pins P1 to P3, for example, and define the overall observation direction based on the weights. Specifically, the acquired three-dimensional data may include a weighting factor for each of the pins P1 to P3. And the observation direction prescription | regulation part 27 may prescribe | regulate the individual observation direction about the pin with the largest weight among pins P1-P3 as a whole observation direction. Further, for example, the observation direction defining unit 27 may define the individual observation direction of the item having the largest value of (each observation area of the pins P1 to P3) × (weight coefficient) as the overall observation direction.

  Note that the item model unit 25a models the pins P1 to P3 when the assembly of the item group A is completed, for example, when incorporated in a mold, from the three-dimensional data. Therefore, for example, the display data generated by the item model unit 25a indicates the posture and arrangement of the pins P1 to P3 at the time of assembly, and an image display based on the display data is performed on the model display unit 12b. Further, even when the observation direction to be described later is changed, the arrangement relationship of the pins P1 to P3 during assembly is clearly displayed.

  Next, the item group information display part 12c is provided with the part which displays the item group name, the item name, and the number of items by a character etc., as shown in FIG. 4, for example. Moreover, in this embodiment, the item group information display part 12c is provided with the selection reception part 12c1 which has a part (for example, check box) which receives selection of an item (pin 1-P3). Selection by the user of the selection reception portion 12c1 corresponds to reception of designation of an item in the display conditions acquired by the display condition reception unit 26.

  Next, the item information display unit 12d includes a display portion that shows detailed information of each item. For example, the item information display unit 12d includes a part that displays the material, hardness, surface treatment, and the like for each item as characters as the manufacturing conditions acquired by the manufacturing condition acquisition unit 23. In addition, the item information display unit 12d includes a selection receiving portion 12d1 that includes a portion (for example, a selection box) that receives selection of manufacturing conditions for each item. Selection by the user of the selection receiving portion 12d1 corresponds to acquisition of the manufacturing condition of the item acquired by the manufacturing condition acquisition unit 23.

  Next, the cost display part 12e is a part which displays the price and delivery date of an item group in this embodiment. As shown in FIG. 4, information related to the manufacturing cost determined by the cost determination unit 24 is displayed on the cost display unit 12 e by characters or the like.

  Next, with reference to FIGS. 5 to 8, display data indicating the individual observation directions defined by the observation direction defining unit 27 and the model of the item group A generated by the display data generating unit 25 along the individual observation directions will be described. To do.

  FIG. 5 is a diagram schematically showing the individual observation direction of the pin P1 defined by the observation direction defining unit 27. As shown in FIG. FIG. 5 is an enlarged view of the model display unit 12b of FIG. In this embodiment, as shown in FIG. 5, the observation direction defining unit 27 defines three individual observation directions D1a, D1b, and D1c as individual observation directions for the pin P1. For example, each of the individual observation directions D1a to D1c can be defined as an observation direction in which the shape of the solid (here, the flange portion and the shank portion) is most clearly observed with respect to the pin P1.

  For example, the individual observation direction D1a is a direction defined as an observation direction in which the diameter of the brim portion of the pin P1 is most clearly observed, and the individual observation direction D1c is the most clearly observed diameter of the shank portion of the pin P1. This is the direction defined as the viewing direction. The individual observation direction D1b is a direction defined as an observation direction in which the shape of the extension direction (side surface) of the brim portion and the shank portion of the pin P1 is most clearly observed. The whole of the three individual observation directions D1a to D1c of the pin P1 may be referred to as an individual observation direction group D1.

  FIG. 6 is a diagram illustrating a display example on the information terminal 1 of the display data generated by the display data generation unit 25 when the pin P1 is selected. As shown in FIG. 6, the pin P1 is selected by the check box of the selection receiving portion 12c1 of the item group information display unit 12c. FIG. 6 corresponds to a display example of the model display unit 12b when the pin P1 is selected as a display condition when generating display data.

  FIG. 6 is a display example of the model of the item group A when viewed from the individual observation direction D1b in FIG. In other words, FIG. 6 shows the shape and size of each of the pins P1 to P3 and the relative position and posture between the pins P1 to P3 when the display data generation unit 25 views the item group A from the individual observation direction D1b. This corresponds to the case where the displayed display data is displayed. In order to understand the observation direction, the overall observation direction D0 of the item group A is illustrated in FIG.

  FIG. 7 is a diagram schematically showing the individual observation directions of the pins P2 and P3 defined by the observation direction defining unit 27. 7 is an enlarged view of the model display unit 12b of FIG. 4 as in FIG. As shown in FIG. 7, the observation direction defining unit 27 includes the individual observation directions D2a, D2b, and D2c (individual observation direction group D2) for the pin P2, and the individual observation directions D3a, D3b, and D3c (individual observation) for the pin P3. A direction group D3) is defined.

  FIG. 8 is a diagram illustrating a display example on the information terminal 1 of the display data generated by the display data generation unit 25 when the pin P2 is selected. As shown in FIG. 8, the pin P2 is selected by the check box of the selection receiving portion 12c1 of the item group information display unit 12c. FIG. 8 corresponds to a display example of the model display unit 12b when the pin P2 is selected as a display condition when generating display data.

  FIG. 8 is a display example of the model of the item group A when viewed from the individual observation direction D2b in FIG. The individual observation direction D2b corresponds to the observation direction in which the shape of the flange portion and the shank portion of the pin P2 is most clearly observed.

  Note that, when an item is not specified by the user, the observation direction defining unit 27 may define the individual observation direction based on the weight coefficient for each item. In addition, the observation direction defining unit 27 or the display data generation unit 25 may select an observation direction when generating display data based on the weighting factor for each item.

  Specifically, the observation direction defining unit 27 scores each item based on, for example, the order in which the dimensional tolerance is strict, the order in which the manufacturing cost (price or delivery date) is high, and the order in which the number of solids of the item is large. By performing, weighting for each item may be performed.

  In addition, the observation direction defining unit 27 may define an observation direction in which the overlapping portion between the item and another item is minimized for a specific item as the individual observation direction. In addition, the observation direction defining unit 27 is an observation direction in which the dimension of the item can be displayed most clearly for a specific item as the individual observation direction (for example, the direction in which the interval between the display positions becomes the largest, or the dimension assistance). The direction in which the end of the line can most clearly indicate the end of the solid may be defined.

  FIG. 9 is a diagram illustrating a display example of the display data generated by the display data generation unit 25 and the display mode determination unit 28 on the information terminal 1 when the observation direction is specified as the display condition. FIG. 9 is a diagram illustrating a model of the item group A when the observation direction of the item group A is rotated from the observation direction (individual observation direction D2b) illustrated in FIG.

  The display condition receiving unit 26 receives designation of the observation direction of the item group A when the display data generating unit 25 generates display data. For example, when the user performs an operation of rotating the model of the item group A through the input unit 11 while referring to the model display unit 12b, the display condition receiving unit 26 determines that the designation of the observation direction is received as the display condition. The display data generation unit 25 uses the arbitrary direction designated by the user as the observation direction, and includes display data including a two-dimensional display representing the appearance of the item group A and the dimensions of the pins P1 to P3 with respect to the designated observation direction. Is generated.

  FIG. 9 is a display example of display data based on the designated observation direction. In the present embodiment, the display mode determination unit 28 determines the pin P1 based on the shape of each of the pins P1 to P3 and the relative positions and orientations between the pins P1 to P3 when viewed from the designated observation direction. The display adjustment of each dimension of .about.P3 is performed.

  FIG. 10 is an enlarged view of the model display unit 12b shown in FIG. FIG. 10 is a diagram showing the display data in which the display position of the dimensions is determined by the display mode determination unit 28. In the present embodiment, the display mode determination unit 28 determines the display position of each dimension of the pins P1 to P3 so that the dimension display position of one pin P1 is a predetermined distance from the display positions of the dimensions of the other pins P2 and P3. The display positions of the dimensions of the pins P1 to P3 are determined so as to be separated from each other.

  First, the dimension display part in the pins P1 to P3 illustrated in FIG. 10 will be described. The dimension display part of the flange part of the pin P1 includes a dimension value display part V1a, a dimension line display part L1a, and a dimension auxiliary line display part E1a. Further, the dimension display part of the entire length of the pin P1 includes a dimension value display part V1b, a dimension line display part L1b, and a dimension auxiliary line display part E1b. Similarly, the dimension display part of the flange part of the pin P2 includes a dimension value display part V2a, a dimension line display part L2a, and a dimension auxiliary line display part E2a. Further, the dimension display part of the entire length of the pin P2 includes a dimension value display part V2b, a dimension line display part L2b, and a dimension auxiliary line display part E2b.

  Next, as shown in FIG. 10, the dimension value display portion V1a of the flange portion of the pin P1 is moved away from the dimension value display portion V2a of the flange portion of the pin P2. Further, the dimension value display portion V1b of the entire length of the pin P1 is moved away from the dimension value display portion V2b of the entire length of the pin P2. Specifically, the display mode determination unit 28 determines the display position of the dimension of each item by determining the position of the dimension line in each of the items (pins P1 to P3). Therefore, the position of each dimension value display section and the like is easy to see.

  The display mode determination unit 28 determines not only the display positions of the dimensions as described above but also omits some of the dimension displays. The display mode determination unit 28 determines the display mode of the dimensions of each item by omitting display of at least some of the dimensions (specification information) of each item. For example, the display mode determination unit 28 omits display of dimensions for at least one item having a low weight among the items. For example, as shown in FIG. 9 and FIG. 10, the dimension display of the pin P3 is omitted from the model display unit 12b by the display mode determination unit 28.

  Moreover, the display mode determination part 28 may determine the display mode of display data so that the item may be shown only by the outline about the item which a dimension display was abbreviate | omitted. For example, an item whose dimension display is omitted is an item having a low weight in the item group, and may be unclear with respect to other items. Therefore, by displaying an item whose dimension display is omitted only by the outline, it is possible to clarify the display of an item having a portion overlapping with the item, and the display of the model becomes clear.

  Although not shown, the display mode determination unit 28 may determine (select) the display size, display color, font, and the like for each dimension display. For example, the display mode determination unit 28 may determine the display mode of each dimension so that the display size of the dimension value of the pin P1 is larger than the display size of the dimension value of the pin P2. The display mode determination unit 28 may determine the display mode of each dimension so that the display color of the dimension value of the pin P1 is different from the display color of the dimension value of the pin P2.

  Thus, in the present embodiment, the observation direction defining unit 27 is based on the acquired three-dimensional data, and the individual observation direction (individual observation direction D1a or the like) that is a specific observation direction for each of the plurality of items. And an overall observation direction D0 that is a specific observation direction for the item group. In addition, the display data generation unit 25 generates two-dimensional display data representing the appearance of the item group for any one of the individual observation direction and the overall observation direction.

  Therefore, when displaying a three-dimensional modeled item group in two dimensions, the shape and specification information of the item group and each item are displayed so that the user can easily see, and design support information useful to the user can be shown. it can.

  In addition, the observation direction defining unit 27 of the design support apparatus 2 sets, as an individual observation direction, an observation direction in which an overlapping portion between the one item and another item is minimized for one item among a plurality of items. Stipulate.

  Therefore, not only the whole item group but also each item can be optimally displayed according to each item by defining (defining) the optimum observation direction, that is, the clearest observation direction. be able to.

  Further, the acquired three-dimensional data includes a weighting factor for each of the plurality of items, and the observation direction defining unit 27 sets the individual observation direction for the item with the largest weight among the plurality of items as the overall observation direction. Stipulate. In addition, the observation direction defining unit 27 defines, as the overall observation direction, an individual observation direction for an item having the largest (item observation area) × (weighting coefficient) among a plurality of items.

  Therefore, by defining the overall observation direction in consideration of the individual observation direction, two-dimensional display based on the optimum observation direction can be performed, and a clear item shape or the like can be displayed to the user.

  Moreover, the design support system S which can combine the information terminal 1 and the design support apparatus 2 and can perform a clear item display to a user can be provided. The design support system S also functions as an automatic estimation system that performs cost determination by displaying a clear item to the user. The design support apparatus 2 also functions as an automatic estimation apparatus that performs cost determination by displaying clear items to the user.

  In the present embodiment, the case where the design support apparatus 2 functions as a server having the information terminal 1 as a client has been described. The design support apparatus 2 can function as a server that provides design support information to a plurality of information terminals simultaneously. The design support apparatus 2 may not only provide design support with the information terminal 1, but may also acquire 3D data from the information terminal 1 and provide design support information to other terminals. The design support information may be provided to the information terminal 1 by acquiring three-dimensional data from the terminal.

  That is, in order to provide design support information to an external terminal, the design support apparatus 2 includes a communication unit 29 that transmits display data generated by the display data generation unit 25 or the display mode determination unit 28 to the outside. Just do it. Note that the communication unit 29 may transmit the design support information to the manufacturer as an external terminal. As a result, the designed item group can be ordered directly from the manufacturer. Note that the order from the manufacturer can be made by selecting “Place Order” shown in FIG. 9, for example.

  Further, the present invention can also implement the design support method of the present embodiment using, for example, a general information processing apparatus through the above-described processing steps. That is, each processing step described above can also be realized as a design support method. For example, by performing at least STEP 01, 03, and 12 among the steps shown in FIGS. 2A and 2B, it is possible to provide useful design support by clear item display.

  In the present embodiment, the configuration of the design support apparatus 2 is only an example. For example, when cost determination is not performed, the manufacturing condition acquisition unit 23 and the cost determination unit 24 may not be provided. The display condition receiving unit 26, the display mode determining unit 28, and the basic information storage unit DB may be provided outside the design support apparatus 2. Further, the display mode determination unit 28 may not have a determination function for omitting display of the specification information.
