Method for obtaining frame structure information based on Revit secondary development in combination with Ansys command stream

Abstract

The invention discloses a method for acquiring frame structure information based on Revit secondary development in combination with Ansys command stream. The method comprises the following steps: developing an information export operation interface; creating a structural column and a frame beam of a frame structure model; obtaining geometric information of the structural columns and the frame beamcomponents in order; creating a structural plate; obtaining geometric information of the structural slab components in order; and copying the command stream of the geometric information to Ansys software, and automatically generating a model. The method is used for solving the problem that body cannot be generated or the generated body is in a distorted state due to the extracted geometric information of the Revit frame structure model cannot meet the high requirement of Ansys software on the numbering sequence, the framework model established by Revit software is imported into Ansys software, a model is provided for subsequent analysis operation, the operation of repeatedly inputting key point numbers and coordinates in the Ansys software is avoided, and the application of the building information model in the aspect of structural design is enhanced.

Description

technical field [0001] The invention relates to the technical fields of architectural information and architectural design, in particular to a method for acquiring frame structure information based on Revit secondary development combined with Ansys command flow. Background technique [0002] With the development of building model informatization (BIM), the combined application of 3D models and 2D drawings in actual engineering has realized civil engineering drawing inspection, mechanical and electrical pipeline collision, technical The application of scheme review and integrated information system has changed the traditional construction industry. [0003] At present, the most widely used BIM modeling software for structural component systems is Revit software, which provides various component families, and users can also build family libraries for different structural types through parameterization to avoid repeated modeling. On the other hand, the software provides users ...

Problems solved by technology

[0004] However, due to the huge differences in the modeling methods between different software, it is necessary to comprehensively consider the software differences during the information export process. Perform automatic calculations. If you do not use a certain method to obtain geometric information in an orderly manner, you will not be able to meet the commands of Ansys software to generate volumes through point numbers, resulting in a series of problems such as the inability to generate volumes or the generated volumes in a distorted state.
