Platform door parametric three-dimensional drawing formation method and system

Abstract

The invention discloses a platform door parametric three-dimensional drawing formation method, which is used for parametric drawing of a platform door parametric three-dimensional drawing. The methodcomprises the steps of extracting a design parameter table of a platform door three-dimensional model; assigning design parameter values in the design parameter table to drawing elements of the three-dimensional drawing; according to the drawing elements of the three-dimensional drawing, generating platform door modular three-dimensional parts in a three-dimensional computer aided design drawing tool; and traversing each structure surface of the three-dimensional parts, establishing a matching relationship among different three-dimensional parts, and performing three-dimensional part assembling according to surface names and the matching relationship of the three-dimensional parts, thereby generating the platform door three-dimensional model. For the situations of time and labor consumption of drawing of the three-dimensional drawing in the prior art, drawing parameters are stored in a structured manner previously, so that the parameters are directly called for performing three-dimensional drawing during drawing; and a hierarchical assembly form is adopted, so that the drawing time of the drawing is greatly shortened.

Description

Technical field [0001] The invention belongs to the field of engineering drawing, and specifically relates to a method and system for parametric three-dimensional drawing of a platform door. Background technique [0002] In modern rail transit construction, construction drawings serve as a standard for comprehensive guidance and planning of specific construction technical schemes. Generally speaking, before the construction starts, it is necessary to plan and set the overall construction plan and determine the construction drawings to ensure the accuracy of the construction process. The specific drawings include rail line structure, rail transit platform structure, etc. The rail transit platform structure also includes platform door system drawings. The construction drawings of the platform door system are the basis for the construction of the rail transit station platform, and the design plan needs to be considered and perfected before the specific construction. Therefore, it ...

Problems solved by technology

However, there are few research results and applications of platform doors in the field of BIM design. The construction of high-speed railways, intercity railways, and urban rail transit involves many disciplines. The BIM platforms used by various disciplines are not uniform, and the 3D BIM models are not connected under various modeling platforms. smooth and difficult to convert, which restricts the development of platform doors in the field of BIM
