At present, the mainstream 3D design software includes PDMS and Smartplant3D of Ying Tao Company, which are very high-end software. The former is very complicated to use and takes a long time to learn, and the supporting electrical instrument software Intools is also very difficult to learn. The latter reflects well, but the price is very high, so it is generally not recommended for individuals to study.

At the same time, there is CADWorx at the low end, which is based on the solid model. The operation is relatively simple, but it takes up a lot of memory. The model is too big for the computer to bring.

It is suggested that individuals learn to use Plant-4D of CEA Company in the Netherlands, which is developed based on the popular CAD platform, with simple operation and clear working logic, and can customize any required components. It is also a complete project management system (EIMS) and an instrument electrical module factory-4DE&; I can automatically draw pictures and customize reports, which is quite user-friendly! The price is also much lower!
