随笔分类 - 6. DataExchange
Data Exchange is a key factor in using Open CASCADE Technology (as well as applications based thereon) concurrently with other software such as CAD systems. It provides the openness of OCCT in a multi-software environment, by allowing it to process external data and providing a good level of integration.
摘要：

摘要：Abstract. Today most 3D engineering model data are save to 3D PDF files. Universal 3D(U3D) along side Product Representation Compact(PRC), U3D is the historical foundation used to embed 3D interactive data and models into a PDF file. But PRC is now the preferred and most feature-rich method to embed 3D data into a PDF file. So the paper is focus on to translate OpenCASCADE geometry data to 3D PDF by embedding PRC file.

摘要：Abstract. The OpenNURBS initiative provides CAD/CAM/CAE and computer graphics software developers the tools to accurately transfer 3D geometry between applications. The OpenNURBS C++ source code is clean and fairly simple. The OpenNURBS Toolkit is intended for use by C++ and .NET programmers. The toolkit includes complete source code to create a library that will read and write 3dm files. OpenCASCADE providing services for 3D surface and solid modeling, CAD data exchange, and visulization. Most

摘要：Abstract. DWG is a file format created in the 70’s for the emerging CAD applications. Currently it is the native file format of AutoCAD, a proprietary CAD program developed by Autodesk. Libredwg is a free C library to read and write DWG files. This program is part of GNU project, released under the aegis of GNU. The paper focus on the usage of Libredwg, and use the Libredwg to read a DWG file and output the entities of the DWG to Tcl script for OpenCASCADE Draw Test Harness visualization.

摘要：Abstract. AVEVA Review is used to 3D model visualization for plant or ship design, construction and operation. Taking data from a range of 3D design systems, AVEVA Review delivers a virtual reality view of a plant or ship which users from all disciplines can freely navigate to view areas of interest, communicate ideas or undertake reviews. Use AVEVA .Net can extract model from DESIGN database, and use AnyCAD .Net can visualize the model. This paper mainly focus on the usage of AnyCAD .Net, and a
