CAD files are limited by the platform, and even mobile phones can open them. The file size is small, which is the easiest to use and the most convenient to exchange drawings. The 3D software is mainly used for simulation, which is limited by the platform and has a large file size.
Although intuitive, it is difficult to get started; And it is very important that the price of 3D software is several orders of magnitude more expensive than CAD. Generally, a set of CAD is less than 10 thousand yuan, domestic products are cheaper, and educational versions and the like can be free; But there are hundreds of thousands of three-dimensional software, and tens of millions of full-featured software are not covered.
In the foreseeable future, CAD will always have its place unless the manufacturing technology changes dramatically. In addition, the mainstream 3D software integrates the function of 2D drawing, which can replace AutoCAD to some extent, but it is still not convenient for communication, which also limits its cross-occasion application.
The reason why cad in mechanical field has not been replaced by 3D software is:
1, easy to use, just training for half a month, the basic functions can be used.
2, the production of floor plans (such as assembly drawings, layout drawings, conventional parts drawings, etc.). ) fast and convenient, low requirements for computers. And it conforms to the law of early hand painting.
3, the price is low and the foundation is wide. Suitability and sufficiency are the basis of its long-term existence.
4. Some processing equipment can be imported directly, such as wire cutting and laser cutting.
Although there are so many advantages, 3D software is still overwhelming, especially some large enterprises, large-scale projects, projects with complex shapes and surfaces, models that need to be analyzed, and models with compact internal space are all completed in 3D, and the overall efficiency is n orders of magnitude.
