[0001] The present invention relates to a unit processing system for creating design data such as manufacturing drawings for units. [Background technology]

[0002] At construction sites, the number of workers is decreasing due to the aging of workers and the decline in the number of young people joining the workforce, so efforts are being made to off-site production of various units to be installed on site. In facility construction at construction sites, units are often produced one by one to match the design and building, and unit planning also needs to be done for each site. In order to produce such units, it is first necessary to create construction drawings for on-site construction, and then create design data such as unit production drawings and necessary forms that match the construction drawings.

[0003] For example, the construction support method disclosed in Patent Document 1 includes a construction drawing acquisition step of acquiring a construction drawing, a construction object BIM model creation step of creating a construction object BIM model based on the construction drawing, a processed part BIM model creation step based on a processing drawing created based on the construction drawing, the processed part BIM model creation step having a processing shape information extraction step of extracting processing shape information of each of the multiple processed parts from the processing drawing, and an installation position information extraction step of extracting installation position information of each of the multiple processed parts within the construction object from the processing drawing, and an integrated BIM model creation step of creating an integrated BIM model by incorporating each of the multiple processed part BIM models into the construction object BIM model based on the processing shape information and the installation position information.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. First, a unit processing system 1 of the present embodiment will be described with reference to Fig. 1. Fig. 1 is a block diagram showing the unit processing system 1.

[0012] The unit processing system 1 selects units to be the subject of a unit plan (unitization) from a plurality of types of units, and creates design data such as production drawings and necessary forms suitable for the site for the selected units.

[0013] For example, the unit processing system 1 includes a storage means for storing template models of multiple types of units, an input means for inputting and selecting selection conditions for units for unit planning (unitization), an output means for outputting a template model based on the input selection conditions, an editing means for editing a parameter file of the template model, and a drawing means for creating a production drawing of the unit based on the template model. In this embodiment, an example will be described in which the unit processing system 1 having the storage means, input means, output means, editing means, and drawing means is applied to a user terminal 2 of a user.

[0014] The user terminal 2 includes a control unit 10 configured with a computer such as a CPU, and the control unit 10 is connected to a storage unit 11 such as a ROM, a RAM, a hard disk drive, a flash memory, etc., and a communication unit 12 that communicates with external devices. The control unit 10 is also connected to an operation unit 13 that accepts user operations, and a display unit 14 that displays various screens.

[0015] The storage unit 11 stores programs and data for controlling each unit and various functions of the user terminal 2, and the control unit 10 executes arithmetic processing based on the programs and data stored in the storage unit 11, thereby controlling each unit and various functions of the user terminal 2. The communication unit 12 is connected to be able to communicate with external devices via a network.

[0016] For example, in this embodiment, the storage unit 11 operates as a storage means of the unit processing system 1, and stores template models for each of a plurality of types of units, and stores the template model for each unit in association with a selection condition. The user terminal 2 can accept registration of a template model for a new unit or a unit planned in the past by the user, and store the template model in the storage unit 11.

[0017] The storage unit 11 also stores unit selection software 25, which is a program for selecting one unit from a plurality of types of units; in other words, the user terminal 2 is equipped with the unit selection software 25. The unit selection software 25 operates as an input means and an output means of the unit processing system 1. The control unit 10 operates as a selection condition input unit 20 and a template model output unit 21 by executing the unit selection software 25 in response to a user's operation. In other words, the control unit 10 executes the selection condition input unit 20 and the template model output unit 21 in the unit selection software 25.

[0018] The storage unit 11 stores parameter editing software 26, such as spreadsheet software, which is a program for editing a parameter file of a template model; that is, the user terminal 2 is equipped with the parameter editing software 26. The parameter editing software 26 operates as an editing means of the unit processing system 1. The control unit 10 operates as a parameter editing unit 22 by executing the parameter editing software 26 in response to a user's operation. In other words, the control unit 10 executes the parameter editing unit 22 in the parameter editing software 26.

[0019] The storage unit 11 stores computer-aided design (CAD) software 27, which is a program for creating a production drawing of a unit based on a template model, i.e., the user terminal 2 is equipped with the CAD software 27. The CAD software 27 operates as a drawing means of the unit processing system 1. The control unit 10 operates as the aided design unit 23 by executing the CAD software 27 in response to a user's operation. In other words, the control unit 10 executes the aided design unit 23 in the CAD software 27.

[0020] Specifically, the storage unit 11 stores, as template models of a plurality of types of units, template models of a plurality of unit targets, such as, for example, an "S-class earthquake-resistant frame," a "cold and hot water horizontal unit," and a "Bispy frame," and further stores template models of one or more structural types for each unit target. That is, the plurality of template models stored in the storage unit 11 have different unit targets and structural types, and in the following, for the sake of convenience of explanation, units with different unit targets and structural types are referred to as different types of units. In addition, the storage unit 11 may store, as a plurality of unit targets, template models such as a "refrigerant vertical tube unit," an "air-cooled chiller surrounding unit," an "outdoor unit," a "steel pipe vertical tube post-installation unit," a "plate heat exchange unit," a "through-flow boiler unit," a "return tank surrounding unit," an "oil service tank surrounding unit," a "shell and tube surrounding unit," and a "cooling tower surrounding unit."

[0021] The selection conditions associated with the template model of each unit include a plurality of selection conditions such as, for example, a "major category", a "medium category", a "minor category", etc. That is, a unit is selected by selecting a "major category", a "medium category", or a "minor category".

[0022] The "major category" selection criteria selects the units to be planned (unitized) from multiple unit targets, such as "S-class earthquake-resistant frame," "hot and cold water horizontal unit," and "Bispaya frame." The "medium category" selection criteria selects the unit pattern to be planned from multiple patterns of the unit targets selected in the "major category" as the unit structural type. The "minor category" selection criteria selects the type of equipment to be planned from multiple models of equipment used in units consisting of the unit targets selected in the "major category" and the patterns selected in the "medium category" as the unit structural type.

[0023] For example, when the "major category" is a "refrigerant vertical tube unit", the number of pipe rows is selected as the "medium category", and there is no selection condition for the "minor category". When the "major category" is an "air-cooled chiller surrounding unit", the manufacturer name is selected as the "medium category", and the chiller model is selected as the "minor category". When the "major category" is an "outdoor unit", the manufacturer name is selected as the "medium category", and the outdoor unit model is selected as the "minor category". When the "major category" is a "steel pipe vertical tube post-installation unit", the number of pipe rows is selected as the "medium category", and there is no selection condition for the "minor category". When the "major category" is a "plate heat exchange unit", the form is selected as the "medium category", and the heat exchanger model is selected as the "minor category". When the "major category" is a "once-through boiler unit", the manufacturer name is selected as the "medium category", and the once-through boiler model is selected as the "minor category". When the "major category" is a "return tank surrounding unit", the form is selected as the "medium category", and the return tank model is selected as the "minor category". If the "major category" is "oil service tank surrounding unit", the shape is selected as the "medium category" and the model of the oil service tank is selected as the "minor category". If the "major category" is "shell and tube surrounding unit", the manufacturer name is selected as the "medium category" and the model of the shell and tube is selected as the "minor category". If the "major category" is "cooling tower surrounding unit", the shape is selected as the "medium category" and the model of the cooling tower is selected as the "minor category".

[0024] The storage unit 11 stores, as a template model for each unit, for example, a template parameter file in which various parameters of the unit can be edited, and a template 3D model file in which a 3D model of the unit can be output. The items of the various parameters of the unit may differ for each type of unit, or units of two or more structural types having a common unit target may have common items.

[0025] The template parameter file is executed by the parameter editing software 26 to display various parameters, and a parameter file obtained by duplicating the template parameter file is executed by the parameter editing software 26 to display and edit various parameters. The template parameter file includes a plurality of editable parameters, and further includes a calculation program capable of calculating necessary information based on the parameters. For example, the template parameter file includes a calculation program for an automatic calculation formula required for various calculation sheets such as earthquake resistance calculation, strength calculation, and anchor calculation sheet. In this embodiment, the file before editing is called the template parameter file, and the file after editing is called the parameter file. The template parameter file stores preset initial values ​​of each parameter, and the initial values ​​of necessary information are calculated by a calculation program based on the initial values ​​of each parameter.

[0026] The template parameter file of the "S class earthquake-resistant platform" includes, as multiple parameters, for example, "distance from the upper floor surface to the lower floor ceiling (H1)", "distance from the upper floor floor surface to the underside of the primary steel material (H2)", "distance from the underside of the equipment to the lower floor ceiling (H3)", "distance from the underside of the platform to the lower floor ceiling (H4)", "equipment height", "platform height (H)", "equipment suspension bolt width", "suspension column width (S)", "KH (design horizontal seismic intensity)", and "KV (design vertical seismic intensity)". Furthermore, the template parameter file of the "S class earthquake-resistant platform" includes a calculation program that performs weight calculations based on the parameters.

[0027] The template parameter file of the "horizontal discharge unit for cold and hot water" includes, as a plurality of parameters, for example, for each stage of the piping of the "horizontal discharge unit for cold and hot water", "material setting for each fluid type", "vertical reference pipe", "maximum main pipe diameter of the unit group", "maximum branch pipe diameter of the unit group", "upward extraction", "downward extraction", "left side suspension screw offset", "right side suspension screw offset", "distance between suspension screws", "setting on / off designation and offset value for up to 8 pipes". The template parameter file of the "horizontal discharge unit for cold and hot water" includes, for example, for each pipe, "type", "fluid type", "fluid type label", "flow direction", "material", "size", "maximum size of this pipe", "connection type", "pipe end component arrangement instruction", "pipe length", "branch extraction on / off", "downstream size", "branch pipe (maximum 2 pipes) size", and "extraction direction". The template parameter file of the "horizontal discharge unit for cold and hot water" includes a calculation program for calculating the full water weight and dry water weight of the pipes only based on the parameters.

[0028] The template parameter file of the "Bispyre Frame" includes, as a plurality of parameters, for example, "suspension height (H)", "width (rW)", "height (rH)", "return chamber side suspension position (rP)", "supply chamber", "width (sW)", "height (sH)", "supply chamber side suspension position (sP)", "return side suspension bolt offset (rB)", "supply side suspension bolt offset (sB)", "return chamber removal setting", and "supply chamber removal setting". Furthermore, the template parameter file of the "Bispyre Frame" includes a calculation program for creating an order table for the "Bispyre Frame" based on the parameters, and a calculation program for calculating the angle of the suspension bolt brace and checking its validity.

[0029] The template three-dimensional model file can be executed by the CAD software 27 to display a three-dimensional model, and a three-dimensional model file obtained by duplicating the template three-dimensional model file can be executed by the CAD software 27 to display and deform a three-dimensional model. For example, the CAD software 27 reads a parameter file of one unit and executes the template three-dimensional model file of the one unit to apply the parameters contained in the parameter file to the one unit and deform the three-dimensional model. In this embodiment, the file before deformation is called the template three-dimensional model file, and the file after deformation is called the three-dimensional model file.

[0030] In the unit selection software 25, the selection condition input section 20 accepts the selection input of the selection conditions by the user, and in this embodiment, as shown in Fig. 2, a unit processing screen 30 for accepting the selection input of the selection conditions is displayed on the display section 14. The unit processing screen 30 has, for example, a selection condition area 31, a preview area 32, a unit name area 33, a version area 34, and an open button 35.

[0031] The selection condition area 31 is an area that displays the selection conditions of the unit in a selectable manner. The selection condition area 31 has a major category selection section 31a for selecting the selection conditions of the "major category", a middle category selection section 31b for selecting the selection conditions of the "middle category", and a minor category selection section 31c for selecting the selection conditions of the "minor category".

[0032] The major category selection section 31a is composed of a list such as a drop-down list that lists multiple unit targets, and allows one unit target to be selected from the multiple unit targets. The medium category selection section 31b is composed of a list such as a drop-down list that lists multiple patterns of the unit targets selected in the major category selection section 31a, and allows one pattern to be selected from the multiple patterns. The minor category selection section 31c is composed of a list such as a drop-down list that lists multiple models of equipment used in units consisting of the unit targets selected in the major category selection section 31a and the patterns selected in the medium category selection section 31b, and allows one model to be selected from the multiple models.

[0033] The preview area 32 displays a preview (rough shape) such as a perspective view of the unit selected in the selection condition area 31. Note that the preview area 32 may accept rotation operations and zoom operations of the displayed unit preview.

[0034] For example, when "S-class earthquake-resistant rack" is selected in the major category selection section 31a of the selection condition area 31, the preview area 32 changes and displays the outline shape of the "S-class earthquake-resistant rack" according to the type of equipment suspended from the earthquake-resistant rack. Note that the preview area 32 displays a preview of the "S-class earthquake-resistant rack" when a model is selected in the minor category selection section 31c.

[0035] For example, when a "cold / hot water horizontal unit" is selected in the major category selection section 31a of the selection condition area 31, the preview area 32 changes and displays the general shape of the "cold / hot water horizontal unit" according to the number of piping stages (e.g., 1 to 2 stages), whereas a "cold / hot water horizontal unit" has 8 pipes per stage.

[0036] The unit name area 33 is an area that displays and allows the input of the unit name of the unit selected on the unit processing screen 30. The selection condition input unit 20 may set, as the initial value of the unit name, a name that combines the names of the selection conditions selected in the selection condition area 31, and may insert a predetermined symbol (for example, an underscore) between the names of the selection conditions. The selection condition input unit 20 first displays the initial value of the unit name in the unit name area 33, and further makes the unit name editable in the unit name area 33.

[0037] The version area 34 is an area that displays, in a selectable manner, the version of the CAD software 27 that executes the three-dimensional model file of the unit selected on the unit processing screen 30. The version area 34 is configured with a list such as a drop-down list, and allows selection of one version from among multiple versions of the CAD software 27. Alternatively, the version area 34 may allow selection of the CAD software 27 that executes the three-dimensional model file from among multiple types of CAD software 27.

[0038] The Open button 35 is displayed so as to be pressable to confirm the selection condition selected in the selection condition area 31 and the unit name entered in the unit name area 33. In response to the pressing of the Open button 35, the selection condition input unit 20 confirms the selection condition selected in the selection condition area 31 and the unit name entered in the unit name area 33.

[0039] In the unit selection software 25, the template model output unit 21 copies a template parameter file and a template three-dimensional model file of a template model of a unit that satisfies the selection conditions confirmed by the selection condition input unit 20, and outputs a parameter file and a three-dimensional model file with the confirmed unit name. The template model output unit 21 stores the copied parameter file and three-dimensional model file in the same folder in the storage unit 11. The template model output unit 21 may set in advance a folder for storing the parameter file and the three-dimensional model file, or may display a folder selection screen on the display unit 14 that accepts a selection operation of the folder in response to a pressing operation of the open button 35.

[0040] When outputting the copied parameter file, the template model output unit 21 may start up the parameter editing software 26 by an API (Application Programming Interface) to execute the parameter file.

[0041] Furthermore, when outputting the copied three-dimensional model file, the template model output unit 21 may start up the CAD software 27 by the API to execute the three-dimensional model file.

[0042] In the parameter editing software 26, the parameter editing unit 22 executes the parameter file copied from the template parameter file in the template model output unit 21 by the API as described above or in response to a user operation. In this embodiment, as shown in Figs. 3 to 7, the parameter editing unit 22 displays a parameter editing screen 40 on the display unit 14, which allows the parameters included in the parameter file to be displayed and edited. The parameter editing screen 40 has, for example, a parameter display area 41 and a preview area 42.

[0043] The parameter display area 41 is an area that displays a list of parameters in the parameter file and accepts editing of the parameters. Note that there are non-editable and editable parameters, and the parameter display area 41 displays non-editable parameters as non-editable and editable parameters as editable. The parameter editing unit 22 executes a calculation program included in the parameter file and displays the calculation results in the parameter display area 41 for the corresponding parameters.

[0044] The preview area 42 displays a drawing (front view, rear view, top view, side view, etc.) of the unit showing the location of the parameters, and also displays the location of the parameters in the unit using dimension lines, etc. on the drawing.

[0045] For example, Fig. 3 shows a parameter editing screen 40 for an "S-class earthquake-resistant stand." In the case of a parameter file for an "S-class earthquake-resistant stand," if the model of the equipment that corresponds to the "S-class earthquake-resistant stand" has been determined, the parameters for the "S-class earthquake-resistant stand" include parameters that cannot be edited because they depend on the external shape and dimensions of the equipment. Here, the parameter display area 41 displays the parameters that depend on the external shape and dimensions of the equipment in an uneditable manner.

[0046] FIG. 4 shows a parameter editing screen 40 for the "horizontal cold / hot water unit". In the case of the parameter file for the "horizontal cold / hot water unit", the parameter display area 41 has a layout diagram of the piping for each stage, a general parameter area for displaying and editing general parameters common to each stage, a stage parameter area for displaying and editing stage parameters that can be set for each stage, and a piping parameter area for displaying and editing piping parameters that can be set for each pipe. The parameter editing unit 22 can calculate the weight when the tank is full including the steel material and the total weight according to the type of piping for the "horizontal cold / hot water unit" by using a calculation program, so that the type of steel material required can be automatically selected. When the type of fluid for the "horizontal cold / hot water unit" is selected, the type of piping to be used is specified, so the parameter editing unit 22 narrows down the pipe diameter, calculates the pipe weight, and narrows down the connection type.

[0047] 5 to 7 show a parameter editing screen 40 of "Bispire Frame." In the case of a parameter file of "Bispire Frame," the parameter editing screen 40 has a sheet shown in FIG. 5 consisting of a parameter display area 41 and a preview area 42 for editing parameters, a sheet shown in FIG. 6 for printing out an order table based on the parameters, and a sheet shown in FIG. 7 for printing out a parameter table of related chambers. The parameter editing unit 22 can print out the order table sheet and the chamber parameter table sheet on the parameter editing screen 40 as necessary forms, or output them as electronic data such as PDF.

[0048] In the CAD software 27, the aided design unit 23 reads a parameter file copied from a template parameter file in the template model output unit 21 or edited in the parameter editing unit 22 by the API or in response to a user operation as described above, and executes a three-dimensional model file copied from a template three-dimensional model file in the template model output unit 21. Note that the parameter file and the three-dimensional model file used in the CAD software 27 are stored in the same folder as described above. The aided design unit 23 may further use a copied parameter file as the parameter file.

[0049] In this embodiment, as shown in Fig. 8 to Fig. 13, the support design unit 23 displays an support design screen 50 on the display unit 14, which displays a three-dimensional model created based on a parameter file and a three-dimensional model file. The support design screen 50 may not only display the three-dimensional model, but also enable deformation. The support design unit 23 may also save the three-dimensional model created based on the parameter file and the three-dimensional model file as a new three-dimensional model file.

[0050] Specifically, the aided design unit 23 reads parameters required for the three-dimensional model file from the parameter file and inputs values ​​into parameters with the same names in the three-dimensional model file. As a result, the aided design unit 23 parametrically transforms the three-dimensional model in the three-dimensional model file according to the parameters in the parameter file. The aided design unit 23 has predefined transformation rules and performs parametric transformation of the three-dimensional model within the range of the transformation rules. In the parametric transformation, the aided design unit 23 may restrict dimensions such as length, width, thickness, and weight according to the transformation rules. In the parametric transformation, the aided design unit 23 may change not only dimensions and weight but also part shapes, the number of supporting parts and fastening parts, the necessary steel materials, and the piping intervals according to the transformation rules. For example, as the dimensions and weight increase due to the parametric transformation, parts may be changed to ones with higher strength, or the number of supporting parts and fastening parts may be increased.

[0051] The aided design unit 23 can lay out a three-dimensional model of a unit on a sheet constructed with three-dimensional drawings as a production drawing, and can also lay out two-dimensional drawings of the unit (front view, back view, top view, side view, etc.) on a sheet constructed with two-dimensional drawings of the unit, and can further arrange associated dimension lines on the two-dimensional drawings. When transforming a three-dimensional model based on a parameter file and a three-dimensional model file, the aided design unit 23 changes the size of the three-dimensional model laid out on the three-dimensional drawings or two-dimensional drawings, and changes the dimension lines accordingly. The aided design unit 23 displays a sheet on which the three-dimensional model is laid out on the three-dimensional drawings or two-dimensional drawings on the aided design screen 50. The aided design unit 23 can switch between displaying three-dimensional drawings and two-dimensional drawings in response to a user operation.

[0052] When the unit is an "S class earthquake-resistant stand," the support design unit 23 displays on the support design screen 50 a sheet in which a three-dimensional model of the "S class earthquake-resistant stand" is laid out on a three-dimensional drawing, as shown in FIG. 8, and also displays on the support design screen 50 a sheet in which the three-dimensional model of the "S class earthquake-resistant stand" is laid out on a two-dimensional drawing, as shown in FIG. 9.

[0053] If the unit is a "horizontal cold / hot water unit," the support design unit 23 displays a sheet on the support design screen 50 in which a three-dimensional model of the "horizontal cold / hot water unit" is laid out in a three-dimensional drawing, as shown in FIG. 10, and also displays a sheet on the support design screen 50 in which the three-dimensional model of the "horizontal cold / hot water unit" is laid out in a two-dimensional drawing, as shown in FIG. 11.

[0054] If the unit is a "Bispire Frame", the aided design section 23 displays on the aided design screen 50 a sheet in which a three-dimensional model of the "Bispire Frame" is laid out on a three-dimensional drawing, as shown in FIG. 12, and also displays on the aided design screen 50 a sheet in which the three-dimensional model of the "Bispire Frame" is laid out on a two-dimensional drawing, as shown in FIG. 13.

[0055] If the unit is a "Bispyre Frame", the sheet on which the three-dimensional model is laid out on the three-dimensional drawing is used for confirmation. If the unit is an "S-class earthquake-resistant frame" or a "horizontal hot and cold water unit", the sheet on which the three-dimensional model is laid out on the three-dimensional drawing is framed, and the support design unit 23 can print out the sheet or output electronic data such as PDF as a necessary document to create an order drawing for the manufacturer.

[0056] The aided design unit 23 can use the three-dimensional model based on the parameter file and the three-dimensional model file as a construction model as it is. In addition, the aided design unit 23 can output the three-dimensional model based on the parameter file and the three-dimensional model file as a separate facility CAD model by using an output function provided by the vendor.

[0057] In addition, when the unit is an "S-class earthquake-resistant frame," the support design unit 23 selects L-shaped steel or C-shaped steel as the support part depending on the total weight, which is the sum of the weight of the piping when filled with water and the calculated frame weight, when calculating the shape of the three-dimensional model based on the parameters.

[0058] Furthermore, when the unit is a "cold / hot water horizontal unit," the support design unit 23 calculates the minimum separation value between the upper and lower stages based on the parameters if the piping has two or more stages, and verifies the validity of the separation value between the upper and lower stages input by the user. The support design unit 23 generates straight pipes and joints required for the piping according to the coordinate points of the piping route and joints calculated based on the parameters.

[0059] As described above, the unit processing system 1 according to this embodiment includes the memory unit 11 which is a storage means for storing template models of multiple types of units in association with the selection conditions for each unit, the selection condition input unit 20 which is an input means for accepting input of the selection conditions for the units, the template model output unit 21 which is an output means for outputting a parameter file and a three-dimensional model file corresponding to a template model that satisfies the input selection conditions, parameter editing software 26 which is an editing means for accepting editing of the output parameter file, and computer-aided design (CAD) software 27 which is a drawing means for creating production drawings of the units based on the parameter file and the three-dimensional model file.

[0060] With this configuration, the unit processing system 1 of the present invention can appropriately acquire a template model of a unit that is the target of a unit plan (unitization) by the user from template models of multiple types of units. In addition, the user can modify the three-dimensional model shown in the three-dimensional model file of the template model to suit the site by editing the parameter file of the template model to suit the site. This allows the user to easily create design data such as production drawings and necessary forms for the unit that suit the site.

[0061] In addition, in the unit processing system 1 of the present invention, since the unit production drawings can be created in the back office without preparing the on-site construction drawings, the conventional flow of creating the unit production drawings after creating the on-site construction drawings can be avoided, and the construction period can be shortened compared to the conventional flow. Furthermore, when the situation at the site changes, the conventional flow of repeatedly correcting the construction drawings and the unit production drawings can be avoided, and the change in the situation at the site can be dealt with by modifying the parameter file.

[0062] In this way, the unit processing system 1 of the present invention can reduce the labor involved in drawing units, move away from the dependency on individual tasks for drawing units, propose the best units for each site, improve customer satisfaction, and promote the automation of unit drawing as a future construction model.

[0063] Furthermore, in the unit processing system 1 of the present invention, the selection condition input section 20 inputs the type of unit, the pattern of the unit, and the model of the equipment used in the unit as selection conditions, and the template model output section 21 determines the template model to output from multiple types of units based on the input type of unit, pattern of the unit, and model of the unit.

[0064] This allows the unit processing system 1 of the present invention to be able to handle a wide variety of units by accumulating template models as needed.

[0065] In the above embodiment, an example has been described in which the user terminal 2 is equipped with the unit selection software 25, the parameter editing software 26, and the computer-aided design (CAD) software 27, but the present invention is not limited to this example.

[0066] In another example, the user terminal 2 may be configured without being equipped with the parameter editing software 26, and may be communicably connected to another terminal equipped with the parameter editing software 26, and may transmit a template model or a parameter editing file to the other terminal. In this case, the template model output unit 21 of the user terminal 2 may transmit the parameter file to the terminal equipped with the parameter editing software, and may issue an instruction via the API to start up the parameter editing software and execute the parameter file.

[0067] In another example, the user terminal 2 may be configured without the CAD software 27 and may be communicably connected to another terminal equipped with the CAD software 27 to transmit the template model or parameter edit file and the three-dimensional model file to the other terminal. In this case, the template model output unit 21 of the user terminal 2 may transmit the three-dimensional model file to the terminal equipped with the CAD software, and may use the API to issue an instruction to start the CAD software and execute the three-dimensional model file.

[0068] The terminal on which the parameter editing software 26 is installed and the terminal on which the CAD software 27 is installed may be the same terminal, or may be different terminals.

[0069] In addition, the above description of the embodiments of the present invention describes preferred embodiments of the unit processing system according to the present invention, and therefore may include various technically preferable limitations; however, the technical scope of the present invention is not limited to these aspects unless there is a specific description that limits the present invention.
