异构CAD平台网络零件库系统的研究与实现

为满足不同CAD用户间三维零件资源共享和重用的需求,围绕多CAD平台和网络化,建立了异构CAD平台网络零件库系统体系结构,提出了零件通用三维浏览模型、零件调用与参数化驱动和零件库建库工具的实现方法和过程.并综合应用CAD软件的二次开发接口、AJAX异步通信、Web3D等先进技术,在.NET框架下开发出了针对机电典型行业中标准化、系列化零件三维图形的网络零件库系统,能实现零件三维模型在线浏览和参数化驱动,并能实现对网络零件库数据的有效管理与扩充.

Research and implementation of web parts library based on heterogeneous CAD platforms

Based on heterogeneous CAD platforms and network environment,a system framework of web parts library(WebPlib)is built to share and reuse three-dimensional parts resource between different CAD users.The key implementation methods and process of WebPlib,including common browser models,loading and parametric driven parts and building tools,is given.With the secondary development interface,AJAX(Asynchronous JavaScript and XML)and Web3D technology,a Web parts library system is developed to share and manage many standard graphic files in typical mechanical and electric trades.This system realizes browse and parametric driven parts on the web,and also manages and extends effectively the abundant WebPlib database.
