At present, the CAD software on the market is complicated, and each enterprise is more or less faced with the data exchange between CAD software , because you can't guarantee that your upstream and downstream enterprises use the same CAD software as you . DWG is a data format that most people are familiar with. Two-dimensional CAD big brother Autodesk has already formed an industry standard, so that later CAD developers have to follow this standard to develop, 2D CAD data compatibility. Relatively perfect. 3D CAD software is much more complicated, and data compatibility between them is always a problem. First of all, let's put aside the difficulty of 3D CAD software data compatibility technology, there are certain interest factors. Because software developers deliberately protect their software products from commercial interests, they have caused communication barriers to a certain extent. The author summarizes the history of data interaction and has experienced three changes: 1. The era of surface interaction. The data exchange between the early 3D CAD software was basically done by the IGES format. This format provided an interactive platform and also caused some confusion: the converted model was split into individual surfaces. If you want a complete solid model, you have to fix it. 2. The era of physical and assembly interaction. Later, the progressive maturity of three-dimensional conversion formats such as STEP and Parasolid (X_T) gradually replaced IGES for data conversion of 3D models. The STEP and Parasolid formats effectively protect the converted entity model and assembly relationship, and the integrity of the converted data is superior to IGES. 3. Read the data era directly. With the exchange reading age between people gradually improve software application requirements, the three-dimensional CAD software has finally arrived, a lot of three-dimensional CAD software has other software can read the file, which effectively avoids the problems of the past will need to install a variety of software. For example, CREO can directly read files of software such as Rhino, Solidworks, Inventor, etc.; NX can directly read the format of software such as CATIA, Solidworks, Solid Edge, etc. Even domestically produced Zhongwang 3D can directly read mainstream 3D CAD software files. Formats such as CATIA, PROE, NX, Solidworks, Inventor, etc., have to be said to be a new era. However, in fact, this kind of inter-reading data technology still has major defects, and it is basically completed through the data interface. This means that the work that previously required manual conversion of third-party formats is now done automatically by the system and read into the software . Although the steps are simplified, it is not a "direct open" in the true sense, and the read data still cannot reproduce the modeling parameters. The author believes that the future development of 3D CAD software will be more open and mutually tolerant, giving users a more perfect application experience, otherwise it is very likely to sacrifice on the road of market competition. This is not technically impossible, especially since many software uses the same kernel, and perhaps they are the first to open a new era of data interaction for our users.
