The present invention relates to a three-dimensional data creation system, a three-dimensional data creation method, and a program that can be performed easily and at low cost.

  In a CAD system, in order to handle a design drawing of a building or a workpiece as a three-dimensional image, it is necessary to input three-dimensional coordinates (x, y, z), inclination / rotation angle, etc. for each member constituting it. And requires a lot of labor. For this reason, ingenuity and interface development for simplifying data input have been made, but no significant improvement has been achieved (Patent Document 1).

  There are systems that automate tabulation and integration (volume, etc.) for each Katsura and beam by defining member attributes such as Katsura and beams in addition to simply showing the shape. There are limitations such as inapplicable to simple structures. In addition, this type of system is generally expensive to purchase.

  The above problem is the same when designing equipment piping and ducts. When creating a three-dimensional equipment drawing having attributes, it is basically necessary to create a new drawing. At present, there is no file format that can exchange equipment attributes in three dimensions with applications other than equipment-dedicated CAD, and the operations of three-dimensionalization and attribute definition are complicated and time-consuming work.

In addition, when data is exchanged from general-purpose CAD to dedicated CAD (equipment, CAD for steel frame, etc.), the attributes of individual members cannot be transferred only with graphic data. It is not connected to efficiency and efficiency.

FIG. 1 is a diagram showing a configuration example of a three-dimensional data creation system according to the present invention. The processing operation in the three-dimensional data creation system of the present invention will be described below with reference to FIG.

  First, the data input unit 1 uses a general-purpose CAD (for example, AutoCAD (registered trademark)) for data input. In the data input unit 1, the general-purpose CAD is used to redefine a member to be output by the output display unit 30 as point, line, or plane graphic information from an existing plan view, elevation view, or sectional view ( Trace) or newly input, and input 3D data. In addition, the height, depth, and member name (keyword) of the member are defined as necessary. Hereinafter, an example of data input using general-purpose CAD (in this example, using AutoCAD (registered trademark)) in the data input unit 1 will be described with reference to FIGS. 3, 4, and 5.

  First, as shown in the example of the layer definition screen in FIG. 3, on the layer screen (layer management screen), each member (for example, symbols G1, G2, B1, A layer name is defined for each member indicated by B2. For example, as shown in FIG. 3, for the layer G1, the layer color G1, G2, G3, B1, B2 is defined such that the line color is defined as “Red” and the line type is defined as “Continuous”. , And B3 define the line color and line type.

  Next, three-dimensional data is input. Based on the CAD original drawing (two-dimensional drawing) shown in FIG. 4A, a single line trace or a new input is made for each member (column or beam) code (layer name).

  In addition, as shown in FIG. 5, when calculating | requiring the quantity of a steel frame or RC frame, it should put a line in the core of Katsura, a beam, and a wall, and when specifying an interior finishing area, line inside a wall. To put.

  When the data input by the data input unit 1 (CAD data input) is completed, the data input unit 2 then defines the attributes of the members defined (input) by the data input unit 1 using spreadsheet software. Attributes to be defined include the shape of the member, unit weight, cross-sectional area, rotation angle, and the like. FIG. 6 shows an example in which attribute information is input from spreadsheet software. Note that the example shown in FIG. 6 is an example using spreadsheet software (EXCEL (registered trademark)).

  In the example of FIG. 6, first, attributes of the entire drawing are defined. That is, the file name traced by the data input unit 1 is “S-01.dxf (DXF file)”, the drawing origin (X axis / Y axis / Z axis) of the dxf file is “1500, 2000, 0”, dxf The drawing scale (magnification to the original size) of the file is “1, 1, 1” for (X axis, Y axis, Z axis), and the three-dimensional direction vector in the X axis direction in the drawing of the dxf file is “1, 1. “0, 0”, the three-dimensional direction vector in the Y-axis direction in the dxf file drawing is “0, 1, 0”, and the three-dimensional rotation axis direction vector / rotation angle in the dxf file drawing is “0”. , 0, 0, 1 ”, and the three-dimensional movement coordinate X axis / Y axis / Z axis of the dxf file drawing are defined as“ 0, 0, reference height (reference point of Z axis) ”.

  Next, a section and a quantity total are specified in the line segment information traced by the general-purpose CAD of the data input unit 1 for each member using commands and parameters. The example shown in FIG. 6 is an example of a screen when a section is designated for each member by a SECTION command (section designation). As other commands that can be used, for example, various commands illustrated in FIG. 7 are prepared. Note that commands necessary for processing can be defined using VBA (Visual Basic for Applications (registered trademark)) or macros provided in spreadsheet software.

  When the data input in the data input unit 1 and the data input unit 2 is completed, the CAD data (trace data) input from the data input unit 1 is stored in the CAD input data storage unit 1a (arrow a in FIG. 1). The tabular attribute data input to the data input unit 2 is stored in the table input data storage unit 2a (arrow b). The data stored in the CAD input data storage unit 1a and the table input data storage unit 2a is based on CAD attribute data (layer name, line color, line type, etc.) input in the data input unit 1 for each member. Thus, the association is performed by the processing unit 10 (arrow c).

  Therefore, the data stored in the CAD input data storage unit 1a and the table input data storage unit 2a is delivered to the processing unit 10 (arrow d). FIG. 2 is a diagram illustrating a configuration example of the processing unit 10. The processing unit 10 includes a graphic sorting processing unit 11, a shape change processing unit 12, an integration setting processing unit 13, an event setting processing unit 14, and an output setting processing unit. 15 is provided.

  In the processing unit 10, first, the graphic sorting processing unit 11 sorts data (CAD input data) in the CAD input data storage unit 1 a into point graphics, line graphics, surface graphics, solid graphics, and character graphics. Each classified figure is subjected to shape change processing by the shape change processing unit 12, integration setting processing by the integration setting processing unit 13, and event setting processing in accordance with a command (command: see FIG. 7) stored in the table input data storage unit 2a. Event setting processing by the unit 14 and output setting processing by the output setting processing unit 15 are performed and sent to the output data storage unit 20.

  The shape change processing unit 12 changes the graphic data stored in the CAD input data storage unit 1a to another graphic in accordance with a command (command) stored in the table input data storage unit 2a (however, character graphics are excluded) Is). For example, the line figure in the CAD input data storage unit 1a is three-dimensionalized based on the cross-sectional data defined by the attribute data in the table input data storage unit 2a. Further, for example, the surface figure in the CAD input data storage unit 1a is three-dimensionalized based on the thickness data defined by the attribute data in the table input data storage unit 2a.

  The integration setting processing unit 13 integrates the graphics in the CAD input data storage unit 1a in accordance with the commands (commands) in the table input data storage unit 2a (however, character graphics are excluded). For example, the weight is calculated by multiplying the volume of the solid figure in the CAD input data storage unit 1a by the specific gravity defined by the attribute data in the table input data storage unit 2a. Further, for example, the amount of money is calculated by multiplying the length of the member data line in the CAD input data storage unit 1a by the unit price defined by the attribute data in the table input data storage unit 2a.

  The event setting processing unit 14 performs event processing on the graphic in the CAD input data storage unit 1a according to an instruction (command: see FIG. 7) in the table input data storage unit 2a. For example, event information such as date / time, movement information, presence / absence information defined by attribute data in the table input data storage unit 2a is added to the graphic in the CAD input data storage unit 1a.

  The output setting processing unit 15 performs various output settings for the graphics in the CAD input data storage unit 1a according to instructions in the table input data storage unit 2a. Data output from the output setting processing unit 15 is stored in the output data storage unit 20 (arrow e in FIG. 1).

  Further, the data in the output data storage unit 20 is transferred to the output display unit 30 (arrow f in FIG. 1). The output display unit 30 uses the data stored in the output data storage unit 20 to perform CG image display, CAD display of an arbitrary cross section, tabulation for each member, and the like.

  For example, as shown in FIG. 8A, various types of 2D (two-dimensional) CAD data can be displayed according to the purpose by using a general-purpose CAD (AutoCAD (registered trademark) or the like). For example, it is possible to display the weight for each steel frame member, or to use it for additional changes or a lifting plan meter. Further, as shown in FIG. 8B, 3D (three-dimensional) CAD data display can be performed using general-purpose CAD (AutoCAD (registered trademark) or the like). With this 3D display, it is possible to check fine dimensions, examine construction plans, and the like.

  Further, the output display unit 30 can display the data of the quantity calculation result using general-purpose spreadsheet software as shown in FIG. 9 using the data stored in the output data storage unit 20. As shown in this example, since the quantity calculation result can be converted into data in units divided by layers, it can be processed into a total according to the purpose. For example, the number of steel frames, decks, painting, fireproof coating, finishing, etc. can be tabulated.

  Furthermore, by transferring part or all of the data in the output data storage unit 20 in accordance with the data format of each dedicated three-dimensional CAD software, data input and processing to the three-dimensional dedicated CAD can be partially automated. As a result, it becomes possible to automatically create a three-dimensional model such as equipment pipes and ducts and to integrate the quantity with equipment-specific CAD software having a function of reading the received data. In the same manner, it is possible to automatically create a production drawing and integrate the quantity of a dedicated CAD for a steel frame. Furthermore, the present invention can be applied to other three-dimensional CAD.

  As a specific example, for example, as shown in FIG. 10A, 3D display is performed with plug-in software for VRML (for example, Cosmo Player (registered trademark)) using data in the output data storage unit 20. It can be performed. In addition, as shown in FIG. 10B, 3D presentation display can be performed using 3DCG dedicated software (for example, POV-LAY (registered trademark)).

It may be configured by a memory and a CPU (central processing unit), and a program (not shown) for realizing the function of the processing unit may be realized by loading the memory and executing the program.

  Also, a program for realizing the functions of the processing units shown in FIGS. 1 and 2 is recorded on a computer-readable recording medium, and the program recorded on the recording medium is read into a computer system and executed. Thus, the processing necessary for each processing unit shown in FIGS. 1 and 2 may be performed. Here, the “computer system” includes an OS and hardware such as peripheral devices.

Furthermore, the “computer-readable recording medium” dynamically holds a program for a short time like a communication line when transmitting a program via a network such as the Internet or a communication line such as a telephone line. It also includes a device (transmission medium or transmission wave) and a device that holds a program for a certain period of time, such as a volatile memory inside a computer system serving as a server or client in that case. The program may be for realizing a part of the functions described above, and further, a program that can realize the functions described above in combination with a program already recorded in a computer system, a so-called difference file (difference). Program).
