Problems solved by technology

Such method has the following disadvantages: one, the construction cost is high
The hard-coded method relies on professionals who have both civil engineering and computer knowledge to interpret the norms, so that the civil engineering norms are manually written one by one into executable codes in a specific computer language, which is time-consuming and laborious
On the one hand, manual interpretation can only interpret the normative provisions into a certain kind of executable code, which can only be applied to a specific computer language or operating environment. When the computer language or operating environment changes, it needs to be redone. Specification interpretation makes it difficult to expand the specification
On the other hand, the existing BIM drawing review method is based on the BIM model in a specific format. BIM models created by different software may be incompatible, making it difficult to expand the model
3. High maintenance cost
The maintenance cost of the existing BIM drawing review system is high. Because the construction industry will often have new code provisions or modify the code provisions, users cannot make timely changes as needed. All code changes rely on professionals to discover and maintain

Embodiment 1

[0026] This embodiment discloses a BIM intelligent drawing review method for standard automatic interpretation, such as figure 1 As shown, at least the following steps are included:

[0027] 1. Structuring and pre-processing the specifications according to drawing approval requirements.

[0028] Find out whether the input specification clauses have been included in the specification library. If the relevant specification clauses have been stored in the specification library, the user can directly select the corresponding specification and executable code, without the need for structuring, preprocessing and unpacking of the specification clauses. translation process. If there is no corresponding specification in the specification library, after formatting and pre-processing the specification clauses, interpret the specification clauses into a computer-executable language and commands through steps 2 to 4, and output them in the form of text. The structuring and preprocessing ...

Embodiment 2

[0041] Based on the same inventive concept, this embodiment introduces specific normative clauses and tests the effect of the drawing review method, so as to illustrate the scheme in the first embodiment through specific data. The schematic diagram of the effect of the embodiment is as figure 2 shown.

[0042] This embodiment discloses a BIM intelligent drawing review method for standard automatic interpretation, which at least includes the following steps:

[0043] 1. Structuring and pre-processing the specifications according to drawing approval requirements.

[0044] In this embodiment, the mandatory specification clauses in Chapter 3 Factory Buildings and Warehouses of the "Code for Fire Protection Design of Buildings" GB 50016-2014 (2018 Edition) are selected as the specification clauses. Split and structure the full text of the specification according to the characteristics of the specification as well as the numbering and format characteristics of chapters and articl...

Embodiment 3

[0079] Based on the same inventive concept, this embodiment discloses another BIM intelligent drawing review method for automatic specification interpretation, which converts specification provisions into specification review codes that can be executed by Autodesk Revit models. In this embodiment, four specification clauses are selected as examples for code generation, which can be generated as specifications that can be executed by a Revit Model Checker (Revit Model Checker). The four selected articles are shown in Table 7. These specifications are described in XML format and are called XML CheckSet. XML Check Set can represent the specification of If-Then format for the Revit model checker to perform the review, which is implemented by defining the result condition of the check as "FailMatchingElement", that is, if a matching element is found, the review will fail. For example, the specification "if A then B" can be expressed by the matching of "A and(not B)", that is, if t...

Abstract

The invention belongs to the technical field of building drawing auditing, and relates to a BIM intelligent drawing auditing method and system capable of automatically interpreting specifications and a medium, and the method comprises the steps of carrying out the structuring and preprocessing of the specifications according to drawing auditing demands; performing semantic annotation and grammar analysis on the standard articles, so that a syntax tree is established; establishing a mapping relationship between keywords of standard terms in the syntax tree and computer language terms; converting the standard article into a computer drawing checking command according to the mapping relation; and performing drawing checking on the BIM model according to the computer drawing checking command, and outputting a drawing checking result. According to the invention, the standard construction cost is reduced, the user can input the standard expressed by the natural language according to the review requirement of the user, the standard does not need to be written into executable codes in a specific computer language one by one by depending on professionals, and the construction cost of the review standard is reduced.

Description

technical field [0001] The invention relates to a BIM intelligent drawing review method, system and medium for standard automatic interpretation, belonging to the technical field of architectural drawing review, and in particular to the field of automatic drawing review of BIM three-dimensional building models. Background technique [0002] Public regulations, codes and standards stipulate the requirements that buildings need to meet in the process of design, construction, operation and maintenance. At present, it is necessary to manually check the compliance of building regulations and architectural drawings on 2D design drawings based on lengthy standard codes, knowledge and experience, and according to cumbersome procedures. In the face of massive drawings and construction data, the manual compliance review method is time-consuming, has high labor costs and relies on subjective judgment, which is prone to errors. [0003] Automated Compliance Checking (Automated Complian...
