Problems solved by technology

[0003] When the current design units carry out the forward design of structural BIM, the checking method still adopts manual checking, and the result is that it takes too long and seriously affects the entire design progress. Reliability of Check Results
Once the results of BIM design documents are unreliable, it will easily lead to failure to provide reliable information data for downstream construction and operation and maintenance links

Embodiment 1

[0049] A Revit-based BIM forward automatic calibration method for building structures, please refer to figure 1 , including the following steps:

[0050] 1) Data storage: read the calculation model data, and store the calculation result data of the calculation model into each component of the matching BIM model through the matching rule from strict to loose; because there may be some deviations between the calculation model and the BIM model , it is difficult to map accurately one-to-one between the calculation model components and the BIM model components. The above problems can be solved by adopting the matching rule from strict to loose. The operation process of the matching rule from strict to loose is: first give a very small The tolerance condition a is used to calculate the matching between the model components and the BIM model components, and mark the matched components; if there is a component that has not completed the matching under the tolerance a condition, then...

Embodiment 2

[0086] A Revit-based forward automatic calibration method for building structure BIM, comprising the following steps:

[0087] 1) Checking of floor construction drawings, including the following steps:

[0088] a) BIM model and calculation model matching check, that is, BIM model and calculation model floor matching check and BIM model and calculation model support matching check;

[0089] Wherein, the specific method for checking the matching between the BIM model and the calculation model floor is as follows: read the floor reinforcement information in the calculation model to form an array A, read the floor information in the BIM model to form an array B, and use the mathematical ray method, Match the floors in the array A with the floors in the array B; the specific matching operation process is: traverse the array A, get the element A1 in the array; under this condition, traverse the array B, get the element B1 in the array B, if The distance between the coordinates of t...

Abstract

The invention relates to the technical field of computer software application, and particularly discloses a Revit-based building structure BIM forward automatic checking method which comprises the following steps of association matching of a BIM model and a calculation model, data storage, automatic checking of a floor construction drawing, automatic checking of a column construction drawing, automatic checking of a wall construction drawing and automatic checking of a beam construction drawing. In order to solve the problems that the consumed time is too long and the reliability of a check result is difficult to guarantee due to manual check, the matching of a BIM model and a calculation model is completed according to the method through a strict-to-loose matching rule, the design relatedinformation in the calculation model is stored into a corresponding BIM model component, association between the BIM three-dimensional model and the two-dimensional detail drawing is completed through an index matching rule and a plane relationship from strict to loose matching rule, then the design file is automatically checked according to national standards and industry specifications, so thatthe checking efficiency is effectively improved, and the reliability of a design result is ensured.

Description

technical field [0001] The invention relates to the technical field of computer software applications, in particular to a Revit-based BIM forward automatic checking method for building structures. Background technique [0002] With the continuous development of construction industry informatization, Building Information Modeling (BIM, or Building Information Modeling), as a computer-aided design technology that contains all the information required for architectural design and presents its information in a three-dimensional model, is used in building structures. widely used in design. [0003] When the current design units carry out the forward design of structural BIM, the checking method still adopts manual checking, and the result is that it takes too long and seriously affects the entire design progress. Reliability of check results. Once the results of BIM design documents are unreliable, it will easily lead to failure to provide reliable information data for downstre...
