Description

Construction and use method of assembled component and part family library based on Revit Technical Field The invention belongs to the technical field of constructional engineering, and particularly relates to a construction and use method of an assembled component and accessory family library based on Revit. Background The application of BIM technology makes the building design, construction and management process more digital and intelligent, which not only improves the overall efficiency of the project, but also greatly promotes the increase of the demands of BIM customized building element families, thereby ensuring the effective transmission of digital information in the whole life cycle process of the building. Compared with the component and accessory family of the traditional software company, the assembled component and accessory family has the characteristics that besides meeting the requirement of daily building a geometric model, the materials, construction process and sequence are described in detail. The traditional component and accessory family generally refers to the component and accessory family containing geometric information and a small amount of size parameters, and the assembled component and accessory family has high standardization degree, strong combinability and more carried information. At present, the component and accessory family products in the market are all developed by BIM software companies, and no product aiming at adapting the assembly type concept and combining construction exists. At present, the conventional practice of building blocks based on Revit software is divided into the following: 1) Downloading the free or paid finished product component and accessory family on the network; 2) The component and accessory family library provided by BIM software company is called for use; 3) The method comprises the steps of self-constructing a fitting family library, drawing only appearance forms and not having data information for fitting with complex parameters; 4) Extracted from other modeled items. The above-mentioned several conventional approaches have the following drawbacks: 1) Only meets modeling requirements, geometric irregular constraint, single parameter and no later use requirements; 2) The standards are not uniform, the unified naming is not realized, and the management mode is disordered; 3) Excessively complex families of building blocks or improper nesting in use and drawing may lead to file corruption; 4) Global linkage cannot be realized; 5) The component and accessory family libraries among all platforms, enterprises and even projects are mutually independent and difficult to share and reuse under the authorized influence of BIM software companies; 6) The use of encryption-free protection results in loss of BIM component family database data assets. Disclosure of Invention In view of the drawbacks existing in the prior art, the invention aims to provide an efficient assembly model building mode which accords with an actual building process, form reusable digital assets, realize informatization, standardization and systematic management of constructional elements, support full-industry chain service of a building, provide basic support for application of a BIM model and break the current barrier of the industry.
