BIM lintel generation method based on list item

Abstract

The invention discloses a BIM lintel generation method based on list items. The method comprises the following steps: 1, picking up all doors and windows under a secondary structure; 2, classifying and identifying all walls under the secondary structure according to list items; step 3, repeatedly generating and judging, and checking whether a lintel is generated at a target position before generating a new lintel; if not, continuing the next step; if the lintel has been generated, performing the next step; step 4, performing door and window width acquisition under a secondary structure, and defining a data source for door and window width acquisition; step 5, performing door and window top height acquisition under a secondary structure, and defining a data source for door and window top height acquisition; 6, setting a support, and defining a support rule generated by a lintel; step 7, exceeding setting: setting a processing scheme when the lintel exceeds the wall range; and step 8, creating the lintel according to the size and position information of the lintel. Through application of the method, the problems of accuracy and feasibility of lintel generation in the BIM model can be solved.

Description

technical field [0001] The invention relates to the technical field of computer-aided design, in particular to a BIM generation lintel method based on list items. Background technique [0002] With the policy requirements of refined management of construction projects and information management, under the BIM model acceptance system, in addition to submitting traditional project materials and drawings, BIM models and data materials are submitted simultaneously, usually in the rvt format file of Revit software. host. The use of BIM technology for design and simulated construction can effectively control the quality and cost of project construction plans, and help to identify design and construction problems in advance and reduce rework. With the gradual maturity of the application of BIM technology, its modeling depth is also increasing, and the coverage rate of the usual structure, construction and installation projects can be close to more than 90%, but some parts are stil...

Problems solved by technology

[0005] In view of the above-mentioned defects of the prior art, the present invention provides a BIM generation lintel method based on checklist items. The purpose of realization is to start from the generation of lintels and generate components based on checklist items, which can effectively solve the problem of building such components. At the same time, it can solve the problem of inability to define rules due to insufficient default classification of BIM software, and has good practical value for construction quality, design efficiency, and measurement accuracy.
