Two-dimensional electronic technical drawing format conversion and vectorization interaction system

Abstract

A two-dimensional electronic technical drawing format conversion and vectorization interaction system comprises a data conversion module, an animation production module, an SVG output module and a browsing interaction module. The data conversion module reads and identifies an entity object and attribute information thereof of the externally input two-dimensional electronic technical drawing, converts the entity object and the attribute information thereof into corresponding SVG information, updates coordinate values of all SVG primitives, and outputs the updated SVG information to the animation production module. The animation production module is used for adding animation description information to the specified SVG primitive and storing the animation description information in a temporary SVG document. The SVG output module stores the temporary SVG document as an SVGP file. And the browsing interaction module is used for loading the SVGP file, interacting with a user, monitoring andresponding to mouse operation and hot spot input of the user, playing animations and displaying hot spot associated contents. The method can be used in a cross-platform mode, is small in workload, simple in file and high in loading speed, does not need to manufacture a 3D product model, and saves time and labor.

Description

technical field [0001] The invention relates to a two-dimensional electronic technical drawing format conversion and vectorization interactive system, which belongs to the field of information technology. Background technique [0002] Two-dimensional electronic technical drawings have been widely used in aerospace and other engineering machinery fields. Based on two-dimensional electronic technical drawings, it is important to carry out aerospace and other engineering machinery equipment design, assembly simulation, production, technical training and other work to improve product quality. significance. Two-dimensional electronic technical drawings have become the output and manufacturing basis of the development of aerospace and other engineering machinery equipment, and are used for data information transmission across departments and processes. Most of the current two-dimensional electronic technical drawings are stored in DWG, DXF (document format produced by AutoCAD sof...

Problems solved by technology

In the application of aerospace and other engineering machinery equipment installation, auxiliary maintenance, logistics support, technical training, etc., only the structural composition, assembly relationship, mechanism movement principle, electrical The working principle, hydraulic transmission principle and other aspects are not intuitive and vivid enough. In order to make designers, manufacturers, users and maintenance personnel familiar with and understand the knowledge of product use and maintenance guarantee as soon as possible, it is necessary to provide an intuitive , image, and easy-to-understand ways to achieve better results

[0003] There are two solutions at present: 1) show the principle technology by making video animation, such as utilizing Flash animation, but the Android system will not support Flash software soon, and the workload of making flash animation is large, and the files are complicated, so this method cannot be obtained for a long time. Use; 2) Demonstrate the principle by making a 3D product model and adding assembly relationship and motion simulation to it, but it takes an average of 2 weeks to a month to make a 3D model, and it takes more time to add assembly relationship and motion relationship in the later stage Long, troublesome to make, time-consuming and labor-intensive
