Description

A BIM library attribute batch processing system for a building information modeling library

The present invention collectively processes parametric parameters and parameter values constituting an object (or a family) constituting basic data of BIM (Building Information Modeling), calculates the time required for parameter input and the operation The present invention relates to a BIM library attribute batch processing system capable of minimizing errors on the BIM library.

Generally, BIM (Building Information Modeling) refers to the process of modeling a facility in a virtual space such as planning, design, engineering (structure, facility, electricity, etc.), construction, maintenance and disposal in a multidimensional virtual space. In recent years, the application of BIM has been widely used in civil and plant fields in Europe and the US because it covers all construction environments as well as construction environments.

In particular, BIM starts with building objects called families, all of which are necessary for building design. Therefore, regardless of the size of the project, it is necessary to have a rich family for effective design work. In addition, it is necessary to create and manage the family to be used as a standard, and to continuously produce the necessary libraries.

When the designer does not have enough support, he or she builds the family on their own, or purchases the family from the outside. In addition to the parameters that determine the shape, the family consists of various types of parameters such as performance, material, and color. Due to the characteristics of the construction industry, it is required to manage various types of parameters and values assigned to them in accordance with the contractor, relations with partner companies, and stages of business execution. Depending on the size of the project, it is necessary to process the information of attributes assigned to thousands of families.

To this end, the attribute input module of the BIM tool has been improved and a separate input module has been added in the process of inputting the data so that no omission occurs in the input of the required attribute value of each object (wall, slab, window, door, roof, A technique for performing a model review procedure has been proposed [Patent Document 1]. However, the above-described prior art basically allows the user to input all the attribute values of the object attribute table when the three-dimensional model of the target building is produced. That is, this technique is a technology that allows the user to input all but input information that is mistakenly input or that is not input automatically.

Therefore, there is a problem that the user or the designer must input the property values of each object of the family one by one in the system. In particular, when dozens or hundreds of library objects are registered in the BIM family, all common attributes and their attribute values must be entered directly through the user interface on the system. Also, when the model project is large, it may be necessary to input the attribute and its attribute value in the state of hundreds of thousands of objects. In this case, the user must enter a number of attributes or attribute values.

Therefore, there is a need for a technique that can conveniently or quickly add or change attributes or attribute values to be added or changed in a lump.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the drawings.

In the description of the present invention, the same parts are denoted by the same reference numerals, and repetitive description thereof will be omitted.

First, a configuration of an overall system for carrying out the present invention will be described with reference to FIG.

As shown in FIG. 1, the overall system for implementing the present invention comprises a BIM system 20 and an attribute batch processing system 30. The library 10 is also a database for storing the family (or objects) of the BIM, which is created or modified or referenced by the BIM system 20. In addition, the worksheet 40 is a file in the form of a spreadsheet, such as Excel, which is created or modified by the attribute batch processing system.

The BIM system 20 refers to commercial software for modeling facilities in accordance with BIM (Building Information Modeling). In other words, the BIM system 20 is a three-dimensional exclusive design software, which can be used as a BIM tool or a BIM software, a modeling tool (or modeling software), an authoring tool, an object- Aided Design). Preferably, the BIM system 20 is an ArchiCAD (trademark) program of Graphisoft, developed by Autodesk, installed in a computer terminal (not shown) or the like It is the program system to be executed.

The BIM system 20 can create (or define) elements necessary for building design as objects called families in advance. The BIM system 20 can take the created objects (or families) and construct them to model facilities such as the entire building. That is, the BIM system 20 constructs buildings three-dimensionally in units of components (families: walls, windows, floors, pillars, etc.) supported by the BIM Modeling software.

Each family is further subdivided by type. Then, the created family basically has a shape that visually expresses the member and properties that express various information about the shape. The attributes are defined by the parameters, and the parameters are used after they are defined first. Therefore, to add a new attribute or attribute value to the family according to the user's need, add the parameter corresponding to the new attribute, and then add the attribute to the corresponding parameter in the family.

The BIM system 20 provides an interface for representing the shape of such a family and for displaying or modifying properties. The interface of the BIM system 20 is a normal GUI (Graphic User Interface), as shown in FIG.

As shown in FIG. 2A, when a created wall object (shape) is selected, a popup window showing properties information is opened. 2B, the component (family: wall, window, floor, column, and the like) supported by the BIM system 20 is a property that is commonly applied to the family unit A property value, and a property value classified by a type. As shown in FIG. 2B, when the 'Edit Type' button of the property pop-up window is input (clicked), a pop-up window showing the type property information is opened. The user can change the attribute value of the corresponding object (e.g., wall) through the attribute pop-up window shown in FIG.

The BIM system 20 also provides API (application programming interface) functions for adding or modifying parameters or family properties, attribute values. An API function is a program function that performs a requested operation according to a call of another program. That is, the API function can input or modify property or attribute values using a program without using the property pop-up window.

In particular, the BIM system 20 can load the library 10 to be described below and use the families registered in the library 10.

Next, the library 10 is a bundle of families (or objects) generated by the BIM system 20, and may exist as a separate file and be loaded onto the system of the BIM system 20. [ For example, a developer can create various types of chairs as family objects, and store them in a single library 10. The user can load already-developed chair-related libraries into his BIM system 20 and use the already created chair families to build their own buildings.

Therefore, the developer can categorize the families into similar categories and provide them to the library. Alternatively, you can bundle different disciplines into one library. Users can then import libraries of the areas they need, load them onto the system, and use the families in the loaded library to model their facilities and the like more quickly.

Next, the attribute batching system 30 is a system for performing (collectively) adding or modifying the attributes of a parameter or a family through the BIM system 20. [ In particular, the attribute batch processing system 30 is a program system separate from the BIM system 20, and is a program system installed and executed on a computer terminal (not shown) or the like.

Preferably, the attribute batching system 30 interfaces with the BIM system 20 via an API function of the BIM system 20. [ The BIM system 20 provides an API function for adding parameters or changing its contents, and also provides API functions for adding or changing properties to or from the family. The BIM system 20 also provides API functions for extracting attributes or attribute values of families. Therefore, the attribute batch processing system 30 calls the API functions of the BIM system 20 to collectively perform the operation of modifying the parameters or the properties of the family.

Further, as another embodiment, the attribute batch processing system 30 may be registered and executed as an add-in type program system of the BIM system 20. [ When each function of the attribute batch processing system 30 is registered in an add-in form, respective functions are displayed on a menu of the BIM system 20 and the like. An example in which the function of the attribute batch processing system 30 is add-in is shown in Fig. Then, the functions of the attribute batch processing system 30 are performed by performing their menus and the like. Examples of screens on which the respective functions are performed are shown in Fig. As shown in FIG. 4A or FIG. 4B, on the BIM system 20 as a separate screen. For example, as shown in FIG. 4A, a separate window in which parameters can be modified is executed, or a separate window in which property information of parameters is exported to a worksheet (or an excel sheet) is executed.

The attribute batching system 30 also stores the attributes of the parameter or family from the BIM system 20 in the worksheet 40 and reads the attributes or property values of the family stored in the worksheet 40 Values to automatically add or modify the contents of the family or parameter on the system of the BIM system 20. An example of storing or modifying the attribute values of the family on these worksheets 40 is shown in Fig.

In addition, the attribute batch processing system 30 provides an interface screen on which the worksheet 40 can be displayed and edited. At this time, the interface screen provides a screen that is the same as or similar to a screen for editing a normal worksheet. Users can change family property or attribute values more conveniently and quickly on the worksheet screen that they are familiar with.

When performing an operation such as referencing or modifying with respect to a family or a parameter, the attribute batch processing system 30 refers to data from the worksheet 40 or post- (40).

In particular, the attribute batching system 30 loads the library 10 into the BIM system 20, selecting the family to be registered in the library 10 and adding or modifying parameters or attribute values of the selected family.

Next, the worksheet 40 refers to a file of a normal spreadsheet. Preferably, the spreadsheet is in the form of a table divided into rows and columns, such as Excel (program trademark of Microsoft Corporation), Lotus (Lotus 1-2-3, program trademark of Lotus Software Corporation), Hansel And is a spreadsheet software program that processes data in each cell.

In the worksheet 40, the data fetched from the BIM system 20 is recorded by the attribute batch processing system 30. At this time, the data recorded on the worksheet 40 are the attributes of the parameter or family, and the attribute values.

In addition, parameters or family attributes (or attribute values) are added or modified on the worksheet 40. That is, when the attribute batch processing system 30 provides a screen for editing the worksheet 40, the content of the worksheet 40 is edited by the user or the developer.

In addition, the contents of the modified worksheet 40 are automatically collectively reflected back to the BIM system 20 by the property batching system 30. In other words, the attribute batching system 30 invokes the contents (modified or added) described on the worksheet 40 in sequence, and, depending on the modified contents, uses the API function of the BIM system 20, Add or modify attributes (or attribute values) of the family.

In particular, the families to be modified are loaded from the library 10, and these modified families are reflected back to the library 10. Therefore, the contents of the family in the library 10 are finally changed according to the contents of the worksheet 40.

Next, a configuration of a BIM library attribute batch processing system according to an embodiment of the present invention will be described with reference to FIG.

As shown in FIG. 6, the BIM library attribute batch processing system 30 according to the present invention includes a family selecting unit 31 for selecting a family to search for a family, a parameter to be newly added to an attribute of the selected family A family storage unit 33 for newly storing the selected family, an attribute extraction unit 34 for extracting the parameters and values included in the selected family into a worksheet, An attribute creating unit 35 for inputting or modifying the attribute values on the worksheet, and an attribute reflecting unit 36 for calling the modified worksheet and reflecting it on the selected family.

First, the family selection unit 31 searches for a family in the library 10, and selects a family to be changed. In other words, the family selection unit 31 requests the BIM system 20 through the API function to search for the family in the library 10.

In addition, the parameter adding unit 32 inputs a parameter to be newly added to the attribute of the selected family. The attributes of the family can be defined from among the already defined parameters. Therefore, in order to add a new property of the family, the parameter must be defined and set first. To this end, the parameter adding unit 32 inputs a parameter to be newly added to the attribute of the selected family. In addition, if a parameter is already defined, it may not be defined by adding a parameter separately.

Further, the parameter adding unit 32 adds the parameter to the attribute of the selected family and inputs the parameter. That is, the parameter adding unit 32 adds an additional property to the selected family as a new parameter. The parameters can be input directly through the user interface, or can be input in a batch, such as a file.

In particular, the parameter adding unit 32 requests to update the data of the family loaded in the BIM system 20, and in fact, the contents of the family are updated in the BIM system 20.

Further, the family storage unit 33 allows the library 10 to store the changed family. That is, it causes the library 10 to update the family to which the attribute (or parameter) is newly added. In particular, the family storage unit 33 requests the BIM system 20 via the API function to store the family in the library 10.

Further, as described below, the family storage unit 33 stores the changed family in the library 10 even when the attribute value of the family is changed.

Further, the attribute extracting unit 34 extracts parameters (or attributes) and values included in the selected family into a worksheet. And extracts parameters representing the attributes of the selected family and their values and stores them in the worksheet 40. [ In the saved worksheet 40, corresponding parameters and their values are stored in tabular form for each family. For each selected family, the parameters (or attributes) of the indicated family are the same as the extracted parameters of the other family. That is, all the extracted attributes of the selected family are extracted.

Next, the attribute creating unit 35 provides the same (or similar) screen as the edit screen of the worksheet on the spreadsheet, and the same user interface (UI) as the user editing the worksheet on the Excel ).

Thus, the user enters or modifies attribute values on the extracted worksheet through the same interface as editing and editing worksheets in Excel (or spreadsheet program system) software.

Preferably, the attribute creating unit 35 may restrict the attribute value to be modified and prevent the attribute name (or parameter) from being modified. The attribute or attribute name is selected from among the parameters and can not be modified unambiguously. Therefore, it is desirable to control to modify only attribute values.

To this end, when creating a worksheet, the attribute creating unit 35 may create an execution module linked to a worksheet provided in a spreadsheet such as Excel together. The execution module is a module (or code) written in a scripting program language such as VBA (Visual Basic for application). The execution module is a module that, when a specific event occurs in a worksheet, executes a function corresponding to each event. Therefore, when the attribute creation unit 35 performs a specific operation such as deletion, modification, or insertion on the worksheet, the function in the execution module is executed according to the job or operation event to perform the related operation. When the parameter such as an attribute or an attribute name is modified, the execution module may control the value to not be changed or output a warning message.

In addition, the attribute reflecting unit 36 calls the modified worksheet to update the attribute values in the selected family according to the contents of the worksheet. In particular, the attribute reflecting unit 36 requests to update the attribute data of the family loaded in the BIM system 20, and in fact, the attribute content of the family is updated in the BIM system 20.

In addition, the attribute reflecting unit 36 modifies the attributes (or attribute values) of each family for all the families included in the modified worksheet. As described above, the attributes of the family, that is, the attribute values are reflected.

These families or selected families are stored in the library 10 by the family store 33.

In particular, the property reflecting unit 36 requests the BIM system 20 via the API function to store the family in the library 10.

Next, a method of adding parameters to a family according to an embodiment of the present invention will be described with reference to FIG.

As shown in FIG. 7, first, the BIM system 20 is executed (S10) and the attribute batch processing system 30 is executed (S20). The attribute batch processing system 30 provides a screen interface to a user, receives commands and the like, and displays the results on a screen. Then, the attribute batch processing system 30 requests the BIM system 20 for an instruction through the API function, and causes the BSI system 20 to execute the contents or command received from the user.

Next, the attribute batch processing system 30 causes the selected family in the library 10 to be selected and loads the selected family (S30). That is, through the BIM system 20, a list of the families registered in the library 10 is displayed, and the families to be updated are selected from the list. Alternatively, the attribute batching system 30 may extract the families in a batch through the search function.

Next, the attribute batch processing system 30 receives the parameters to be added and the feature information thereof, and registers them as parameters to be used in the selected family (S40). The information of the parameter includes the name of the parameter, the family category, the parameter name, the type, the group, the parameter type, and the like. These parameters are newly registered variables that are to be registered as attributes of the selected family.

Next, it is checked whether the input of the parameter is completed (S50). At least one parameter is input, and parameter information is input for each parameter. Check that the input of parameters is completed.

Next, the attribute batch processing system 30 inputs the newly registered parameter as an attribute of the family. In particular, the parameter is added to each of the previously selected families.

Finally, the modified family is stored in the library 10 (S70).

Next, a method of extracting an attribute of a family according to an embodiment of the present invention will be described with reference to FIG.

As shown in FIG. 8, first, the BIM system 20 is executed (S110) and the attribute batch processing system 30 is executed (S120). As described above, the attribute batch processing system 30 provides a screen interface to a user, requests an instruction from the BIM system 20 through an API function, and causes the BSI system 20 to execute contents or commands received from the user.

Next, the attribute batch processing system 30 causes the selected family in the library 10 to be selected and loads the selected family (S130).

Next, a family attribute to be extracted from the selected family to the worksheet is selected (S140). A family property is a content whose contents are changed or newly added.

Next, the attribute batch processing system 30 extracts attributes of the selected family and their attribute values for each selected family, and records them in the worksheet (S150).

Next, a method of collectively reflecting attributes of a family according to an embodiment of the present invention will be described with reference to FIG.

As shown in FIG. 9, first, the BIM system 20 is executed (S210) and the attribute batch processing system 30 is executed (S220).

Next, the property batch processing system 30 loads the stored worksheet (S230). The worksheet shows the identification information, parameters (or attributes), and their attribute values for each family. A worksheet is a sheet on which attributes and their attribute values are extracted and recorded for the family selected above.

Next, the attribute batch processing system 30 provides the user interface of the spreadsheet to modify the property values of the family by the user (S240).

Next, the property batch processing system 30 reflects the family property contents of the BIM system 20 according to the modified worksheet (S250). The attribute batch processing system 30 reads the contents of the worksheet as a family unit and requests the family in the BIM system 20 to modify the attribute contents according to the modification contents.

Finally, when all attribute contents of the family are modified, the attribute batch processing system 30 requests to save the family in the library 10 (S260). Upon request, the BIM system 20 controls to store the information of the loaded family in the library.

Although the present invention has been described in detail with reference to the above embodiments, it is needless to say that the present invention is not limited to the above-described embodiments, and various modifications may be made without departing from the spirit of the present invention.
