网络协同产品开发环境中的三维工程图形批注技术

3D Engineering Drawing Markup Technology in Web-Based Product Developing Environment

针对一般批注软件不能解决的三维工程图形批注问题 ,提出将WindowsAPI函数与图层覆盖技术相结合 ,实现网络环境下产品协同开发过程中的三维工程图形实时批注工具。论述了批注源图形文件的提取、批注元素编辑及批注文件的入库等关键技术。最后 ,介绍了异地协同产品开发环境中批注工具的应用。

The common markup software is not adaptive to the 3D engineering drawings. Using Windows API and layer covering technology, we realized a real time 3D drawing markup tool, which has been used in our web-based collaborative product development environment. How to pick up the original bitmap file, markup the picture and save the markup file are discussed. The application of markup tool in remote collaborative product development environment is introduced.
