摘　　要：为了克服工程制图课程教学的困难,改变传统的教学方法,利用WebGL的第三方库Three.js建立了与工程制图教材配套的虚拟模型,通过编程实现了模型库创建、网页显示功能、模型手动装配功能等,能够在各种手机端、微信端或电脑端查看虚拟模型。通过随时随地的打开模型教学以克服学生对于复杂模型学习难以想象和表达模型空间结构、位置的困难情况,快速提高学生识图和空间思维能力,此方法为工程制图类课程的教学提供了实践依据。In order to overcome the difficulties in teaching engineering drawing course and change the traditional teaching method,the third-party library of WebGL,Three.js sets up a virtual model matching with the teaching material of engineering drawing,and realizes the function of creating the model library,displaying the web page and assembling the model manually by programming,and can view the virtual model on various mobile phone,wechat or computer.By opening the model teaching anytime and anywhere to overcome the students'difficulty in imagining and expressing the spatial structure and position of the model in the study of complex models,the students'ability of reading maps and spatial thinking can be improved rapidly,this method provides a practical basis for the teaching of engineering drawing courses.

关 键 词：Three.js 虚拟模型 工程制图
