Description

Technical Field

[0001] The present invention belongs to the technical field of BIM evaluation, and specifically relates to a method for evaluating the degree of integration of three-dimensional collaborative design. Background Art

[0002] BIM technology has five characteristics: visualization, simulation, coordination, drawing and optimization. This enables the three-dimensional collaborative platform based on BIM applications to perform "three-dimensional rendering, publicity and display", "quick calculation, improved accuracy", "multi-calculation comparison, effective management and control", "precise planning, reduced waste", "virtual construction, efficient collaboration", and "conflict calling, decision support", thereby achieving the goal of improving project production efficiency, shortening construction period and reducing construction costs.

[0003] For the construction industry, the research on 3D collaborative platform technology can not only change the working mode of different professional designers, but also enable all production departments to work under the same model. First of all, it solves the practical problem of no unified operating platform and provides a technically reliable unified platform. For example, when structural professionals modify the column size in the model, the information corresponding to the modified column in the building model will be updated in time. In addition, this technology can also create a collaborative platform for Party A and the construction party.

[0004] 3D collaborative technology can promote the sustainable development of the architectural design industry. It can achieve the goal of reducing building energy consumption in accordance with the standards and requirements of green buildings, and promote the development and progress of building energy-saving technology research. This will be of great significance to environmental protection, promoting the use of renewable resources, and promoting the green and sustainable development of architectural design.

[0005] Current problems with 3D collaborative design:

[0006] Incomplete material coding system and database

[0007] In the current 3D collaborative design application, the imperfection of the material coding system and database is a more prominent problem. It is mainly reflected in the fact that when database personnel are compiling pipeline materials, there is no unified regulation to clarify it, and the material compilation is completely based on personal habits, so it is irregular. Moreover, different database personnel have inconsistent descriptions of the same pipeline material or project. Although the meaning is the same, the order of the text is completely different, which brings great difficulties to the owner when purchasing pipeline materials. This also makes it difficult to unify the description of related materials when generating material summary tables, and lacks rigor. In addition, the inconsistency of the material coding system also makes it difficult to reuse material codes with different descriptions, which greatly increases the workload.

[0008] Low level of professional coordination

[0009] In the process of 3D collaborative design software, the low degree of coordination among various disciplines is also one of the outstanding problems. Due to the large number of 3D software, inconsistent application levels, inconsistent application modes, and the impact of conflicts between traditional design ideas and modern design methods. Taking the PDMS model as an example, in domestic 3D collaborative design, only a very small number of 3D design software can design PDMS models, and most of the other disciplines are not well involved in the design process. In addition, when 3D modeling, not only the pipeline design is designed by the piping engineer, but also other structures are designed by the piping engineer, while most other disciplines are basically not involved in the modeling design, which greatly reduces the application effect of the 3D model.

[0010] The development of 3D collaborative design platform is slow and the standard construction is lagging behind

[0011] Due to the uneven education of 3D designers and the tight project schedule, the advantages of 3D models are difficult to bring into play. In addition, the construction of the supporting management system standards for 3D models is still relatively backward, which also makes it difficult to effectively guarantee the quality of the models. In addition, although 3D design software has strong applicability and is widely used, due to the inconsistency of regulations in various units, there are great differences in application, making it difficult to manage it uniformly. Summary of the invention

[0012] The purpose of the present invention is to provide a three-dimensional collaborative design fusion degree evaluation method in view of the current status of the prior art.

DETAILED DESCRIPTION

[0028] In order to facilitate those skilled in the art to understand and implement the present invention, the present invention is further described in detail below in conjunction with embodiments. It should be understood that the implementation examples described herein are only used to illustrate and explain the present invention and are not used to limit the present invention.

[0029] The 3D collaborative design integration evaluation method includes the following steps:

[0030] Step 1: Count the model information corresponding to the 3D model of 3D collaborative design and create a central file.

[0031] Use data tables to record the model information of the 3D model, including geometric dimension information, material information, process information, and construction suggestions. Create a central file, classify the model information and store it in the central file as the basic calculation base for the model integration degree. The central file is actually the 3D model created by each profession and the related model information sorted out and entered into the central file. Therefore, when creating the central file, each professional designer is required to perform standardized creation of their own 3D model files and provide standardized models for the central file.

[0032] Step 2: Require each professional designer to create local files and their own work sets through the central file.

[0033] Step 3: Each discipline establishes 3D model application standards and sharing principles;

[0034] Step 4. Each discipline establishes local files and link collaboration methods according to the needs of 3D collaborative design, links local files of other disciplines as their own design references, and designs and models on this basis. For example, since civil engineering and electromechanical need to refer to each other, the link collaboration method can be used, and both parties can link each other's local files; designers of each discipline will update the local files of the design to the central file synchronously;

[0035] Step 5: Export and deliver the central file;

[0036] Step 6: Determine the amount of model information that needs to be collaboratively designed in the entire 3D collaborative design;

[0037] Step 7: Determine the degree of participation of each discipline in 3D collaborative design;

[0038] Step 8: Determine the comparative application degree of the 3D model corresponding to the central file in the collaborative design of each discipline;

[0039] Step 9: Determine the weight A1 corresponding to the amount X1 of model information in step 6, determine the weight A2 corresponding to the degree of participation X2 in step 7, and determine the weight A3 corresponding to the degree of comparative application X3 in step 8.

[0040] Step 10: Calculate the integration degree (R value) of the three-dimensional collaborative design of the engineering project according to the following formula.

[0041] R=(A1·X1)+(A2·X2)+(A3·X3)

[0042] Formula (1) can be used to analyze and evaluate the degree of use of 3D collaborative design. The R value will directly reflect the breadth and depth of the use of 3D modeling and collaborative design in construction projects, and is the main evaluation indicator for the quality of 3D collaborative design.

[0043] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
