The term "and/or" as used herein includes any and all combinations of one or more of the associated listed items.
Example 1
Referring to fig. 1, a first embodiment of the present invention is to provide a method for converting a two-dimensional CAD drawing into a BIM model, which includes steps S10-S50:
step S10, a two-dimensional CAD drawing to be shifted is obtained, a shift shifting instruction for controlling the two-dimensional CAD drawing to shift is received, and a target shift shifting task is generated;
firstly, it should be noted that the two-dimensional CAD drawing to be shifted refers to an editable drawing under a two-dimensional view, and in this embodiment, the two-dimensional CAD drawing is a building drawing, such as a two-dimensional CAD drawing in terms of structure, water supply and drainage, and heating and ventilation of a building.
In this embodiment, the conversion of the two-dimensional CAD drawing to the BIM model is performed based on the SaaS platform, which is software as a service (Software as a service), that is, the software service is provided through a network. Compared with the traditional software service, the user of the SaaS platform can acquire and serve by self as required, and service expansion and system upgrading do not affect the use of the user.
Specifically, when a user uploads a two-dimensional CAD drawing to be shifted, after the user determines that the two-dimensional CAD drawing is shifted in the system, namely after the user intention is clear, the shift shifting instruction for controlling the two-dimensional CAD drawing to shift is received, and a target shift shifting task is generated based on the shift shifting instruction and the two-dimensional CAD drawing uploaded in advance.
The task name of the target shift task is a file name of a two-dimensional CAD drawing to be shifted, and of course, the task name of the target shift task can also be a task name set by other users. The task name of the target shift task is set so as to facilitate searching the target shift task and facilitate a user to know the shift process of the two-dimensional CAD drawing.
Step S20, a first task message of the target shift task is sent to a queue server, so that the target shift task is ordered in a total task list of the queue server;
the first task message of the target shift task, namely the prompt message sent by the system after the target shift task is generated, is used for information feedback in the system.
Specifically, a first task message of a target shift task is sent to a queue server, and after the first task message is received, the queue server sorts the target shift task based on the task name of the target shift task and the time of receiving the first task message, so as to sort the target shift task in the last position of a total task list according to time sorting.
Of course, when the situation of the target shift task is urgent, the user can set the priority of the target shift task by himself, for example, the target shift task includes three priority levels, which are urgent, urgent and general. For example, when the priority levels of two or more shift tasks are the same, shift is still performed in the time axis order in the total task list; when the priority of any shift task is higher, the shift task with higher priority is executed preferentially. A certain sequencing time can be saved for the emergency shift task.
Step S30, when the task in the total task list is executed to the target shift task, the target shift task is extracted to analyze the two-dimensional CAD drawing, and a second task message of a professional subtask of the target shift task is sent to a message queue server according to a drawing analysis result;
when the tasks in the total task list are executed to the target shift task according to the time axis and/or the priority, in the embodiment, the target shift task is extracted based on the task name of the target shift task, and the two-dimensional CAD drawing is analyzed, including but not limited to drawing preprocessing, drawing frame analysis, component merging and classification, and primitive information processing of the two-dimensional CAD drawing. After the two-dimensional CAD drawing is analyzed, drawing analysis results can be obtained, and a second task message of the professional subtask of the target shift task is further sent to the message queue server according to the drawing analysis results.
In this embodiment, the message queue servers corresponding to the professional subtasks include building, structure, water supply and drainage, heating and ventilation, and electric message queue servers, that is, the target shift task is split according to the classification of the two-dimensional CAD drawing, and the split professional subtasks are respectively distributed to the message queue servers of each class for sorting.
For example, when a two-dimensional CAD drawing includes two types of drawings, namely, a building and a heating and ventilation drawing, after the two-dimensional CAD drawing is parsed, a target shift task of the two-dimensional CAD drawing is split based on a result of parsing the drawing, building professional subtasks of the target shift task are distributed to a building message queue server for sorting, and heating and ventilation professional subtasks of the target shift task are also distributed to the heating and ventilation message queue server for sorting, so that next processing is performed respectively.
Step S40, when the message queue server receives the second task message, reading the drawing analysis result to obtain drawing analysis data, and packaging a single professional two-dimensional CAD drawing into an IFC data file based on the drawing analysis data and storing the IFC data file;
when the message queue server receives a second task message of a professional subtask distributed by a target shift task, reading an analysis result related to the professional subtask from a database, carrying out reconstruction objectification of each professional, for example, reconstructing three-dimensional information data and attribute information data of a picture paper object according to picture layer data and line data combined with identification logic of a specific object, storing the three-dimensional information data and the attribute information data in a self-defined IFC format, packaging a single professional two-dimensional CAD drawing into an IFC data file, storing the IFC data file in the database, and finally sending the message of task completion to a general control service.
And S50, reading all IFC data files corresponding to the two-dimensional CAD drawing, and automatically creating a BIM model corresponding to the two-dimensional CAD drawing according to the IFC data files.
And reading all IFC data files corresponding to the two-dimensional CAD drawing, namely, IFC data files corresponding to all professions, such as IFC data files corresponding to buildings, structures, water supply and drainage, heating and ventilation and electric professions in the two-dimensional CAD drawing, and automatically creating a BIM model corresponding to the two-dimensional CAD drawing based on all IFC data files.

the target shift task is generated based on a data source of the two-dimensional CAD drawing, the target shift task is ordered in a total task list, when the target shift task is executed, the data source of the two-dimensional CAD drawing is analyzed to obtain a drawing analysis result, and a second task message of a professional subtask of the target shift task is sent to a message queue server based on the drawing analysis result, so that drawing analysis data can be obtained based on the drawing analysis result when the second task message is received, and a single professional two-dimensional CAD drawing is packaged into an IFC data file and stored, and the IFC data file is read to automatically create a corresponding BIM model. By adopting the technical scheme, the conversion of the two-dimensional CAD drawing into the BIM model is completely and automatically carried out in a network environment, no manual assistance is needed any more, and the technical problems that BIM modeling in the prior art mainly depends on manual mode turning based on the two-dimensional CAD drawing, and the input labor cost and time cost are high can be solved.
