Step S210, acquiring a target Revit family occupation representation file matched with a model scene to be constructed.

In this embodiment, the target Revit family occupancy representation file is a Revit family occupancy representation file stored in a family occupancy representation file database and matched with the model scene to be constructed, and the Revit family occupancy representation file is used to describe the distribution condition of the family instance representation identifiers of each of the multiple family instances matched with the corresponding model scene in the whole model scene range. Wherein, each family instance representation identification is used for representing one family instance; the family instance types (such as doors, windows, wardrobes, bedside tables, beds and the like) of a plurality of family instances related to the same Revit family placeholder file can be partially identical or completely different; the respective family instance sizes of a plurality of family instances related to the same Revit family placeholder file can be partially the same or completely different. The model scenario to be built may be, but is not limited to, a standard room, a standard toilet, a standard nurse station, a standard medical unit, a standard office unit, etc.

In an implementation manner of this embodiment, the Revit family placeholder file is stored in a JSON format. After the computer device 10 acquires the target Revit family placeholder file, the target Revit family placeholder file may be loaded into a family placeholder file generating plug-in of a Revit application program, the family placeholder file generating plug-in calls a jar.parse () command using C language and reads a family instance information file existing in a jar format and corresponding to the target Revit family placeholder file in a circular access manner, at this time, the family instance information file may record family instance type information and family instance size information corresponding to each of a plurality of family instance token identifications in the target Revit family placeholder file, and relative position information and family instance attachment relationship of the plurality of family instance token identifications in the same family placeholder schematic diagram. The family occupation diagram is used for representing a model scene to be constructed; the family instance attachment relation is used for indicating whether each family instance representation identifier in the same family occupancy schematic diagram is attached to other family instances or not, and the attachment plane position information and/or the attachment height information when each family instance representation identifier is attached to other family instances.

The family example attachment relationship is illustrated by taking a "wall" family example, a "door" family example, a "chair" family example, and a "window" family example as examples: the family instance attachment relations corresponding to the chair family instance and the wall family instance, the door family instance and the window family instance respectively indicate that the chair family instance and the wall family instance, the door family instance and the window family instance are not attached, the family instance attachment relation between the wall family instance and the door family instance indicates the attachment plane position information of the door family instance attached to the wall family instance and the door family instance attached to the wall family instance, and the family instance attachment relation between the wall family instance and the window family instance indicates the attachment plane position information and the attachment height information of the window family instance attached to the wall family instance and the window family instance attached to the wall family instance.

Therefore, in the embodiment of the application, the family instance representation identifiers are divided into a plurality of types, so that the first family instance representation identifier is used for representing the attached family instance, the second family instance representation identifier is used for representing the family instance which is attached to other family instances and only needs to attach the plane position information, the third family instance representation identifier is used for representing the family instance which is attached to other family instances and needs to attach the plane position information and the attachment height information, the fourth family instance representation identifier is used for representing the family instance which is not attached to other family instances, and then the family instance attachment relationship among the plurality of family instance representation identifiers in the same family occupancy diagram is effectively described by means of assigning the four family instance representation identifiers to the matched family instances.

It is understood that the family placeholder representation file database may be stored in the memory of the computer device 10, or may be stored in a server communicatively connected to the computer device 10.

Step S220, searching a plurality of target Revit family files matched with the model scene to be constructed and the target Revit family placeholder files in the Revit family file database.

In this embodiment, the Revit family file database is configured to store a plurality of Revit family files, where a same model scene corresponds to at least one Revit family file, each family instance type may correspond to at least one Revit family file, and the sizes of the family instances corresponding to the Revit family files of a same family instance type are different from each other; each Revit family file is loaded to a Revit application program to construct a corresponding family instance; the Revit family file database may be stored at the memory of the computer device 10 or at some server communicatively coupled to the computer device 10.

After obtaining the family instance related information of each family instance representation identifier included in the target Revit family placeholder representation file, the computer device 10 may automatically find, in a manner of accessing a Revit family file database, a plurality of target Revit family files substantially matching the model scene to be constructed in the Revit family file database, so as to construct, through the found plurality of target Revit family files, the BIM standard model corresponding to the target Revit family placeholder representation file, where each target Revit family file corresponds to one family instance representation identifier in the target Revit family placeholder representation file.

Optionally, referring to fig. 3, fig. 3 is a flowchart illustrating sub-steps included in step S220 in fig. 2. In an embodiment of the present application, the step S220 may include sub-steps S221 to S224, so as to automatically find a plurality of target Revit family files matching the desired model scenario from the Revit family file database.

And a substep S221, aiming at each family instance representation identifier in the target Revit family placeholder representation file, screening a plurality of candidate Revit family files corresponding to the family instance type information of the family instance representation identifier from the Revit family file database.

And a substep S222, extracting a plurality of Revit family files to be screened which are matched with the model scene to be constructed from the screened candidate Revit family files.

And a substep S223, matching each extracted Revit family file to be screened with the family instance size information of the representation identifier of the family instance.

And a substep S224, taking the Revit family file to be screened, which is matched with the family instance size information of the family instance representation identifier, as a target Revit family file corresponding to the target Revit family occupation representation file of the family instance representation identifier.

Therefore, the application can automatically find out a plurality of target Revit family files matched with the expected model scene from the Revit family file database by executing the substeps S221 to the substeps 224, and recommend the adapted Revit family files to the subsequent BIM model building operation.

And step S230, calling a Revit application program to substitute a plurality of target Revit family files into the target Revit family placeholder files for family instance construction processing to obtain a target BIM standard model matched with the model scene to be constructed.

In this embodiment, after obtaining a target Revit family occupation representation file and a plurality of target Revit family files that are matched with a model scene to be constructed, the computer device 10 may load the target Revit family occupation representation file and the plurality of target Revit family files into the Revit application program, construct a target family instance corresponding to each of the plurality of target Revit family files by the Revit application program, and perform distribution position adjustment on the target family instances of each of the plurality of target Revit family files that are matched according to the target Revit family occupation representation file, so that the target family instances of each of the plurality of target Revit family files are combined with each other to form a target BIM standard model that is matched with the model scene to be constructed, thereby effectively building a BIM standard occupation model that is matched with a desired model scene based on the recommended plurality of target Revit family files and Revit family representation files that are adapted to the desired model scene, assisting a designer, automatically and quickly building a BIM standard model that is matched with the desired model scene, so as to improve efficiency of the BIM model, and reduce loss and difficulty in building a human resource reuse scheme.

In the embodiment of the present application, the step S230 may include sub-steps S231 to S233 to automatically and quickly build a BIM standard model matching a desired model scenario in a model building environment of a Revit application.

And a substep S231, loading a plurality of target Revit family files in the model building environment of the Revit application program, and generating target Revit family instances corresponding to the plurality of target Revit family files respectively.

In this embodiment, the computer device 10 may obtain a standard height of a current model scene to be constructed at the target Revit family placeholder file through an OfCategoryId () function in a filtered element collector, and load a plurality of target Revit family files corresponding to the target Revit family placeholder file into the Revit application program to operate by calling a directory.getfiles () function and a document.loadfamily () function, and the Revit application program calls a document.create.new family instance function to generate a corresponding Revit family instance based on the obtained standard height and the loaded target Revit family file, where at this time, each created Revit family instance is the target Revit family instance corresponding to a certain target Revit family file.

And a substep S232, placing the family examples of the target Revit family examples respectively corresponding to the representation identifications of the family examples in the model building environment of the Revit application program according to the relative position relationship of the representation file of the target Revit family including the representation identifications of the family examples.

In this embodiment, the computer device 10 may map the relative position relationship, including the representation identifiers of the respective family instances, of the target Revit family placeholder file to the model construction environment of the Revit application program to obtain spatial position information of the target Revit family instance, in the model construction environment of the Revit application program, corresponding to the representation identifiers of the respective family instances in the target Revit family placeholder file, and then place the generated target Revit family instances according to the matched spatial position information by calling a document.

And a substep S233, according to the family instance attachment relation of the target Revit family occupation representation file including the representation identifiers of the various family instances, carrying out position adjustment on a plurality of target Revit family instances placed in the model building environment of the Revit application program to obtain a target BIM standard model.

Therefore, the BIM standard model matched with the expected model scene can be automatically and quickly built and formed in the model building environment of the Revit application program by executing the substeps S231-S233.

By executing the steps S210 to S230, a plurality of matched target Revit family files are recommended for an expected model scene, and a BIM standard model matched with the expected model scene is automatically and quickly built by an auxiliary designer based on the recommended plurality of target Revit family files and the Revit family occupation representation file matched with the expected model scene, so that the building efficiency of the BIM model is improved, and the manpower loss and the scheme multiplexing implementation difficulty in the building process of the BIM model are reduced.
