Electrical CAD software is an auxiliary design software developed for electrical specialty. According to different industries, it can be divided into civil electrical CAD, industrial electrical CAD and power electrical CAD. These softwares have developed different functions according to the industry rules and regulations, such as rapid equipment layout, statistical equipment material list, wiring, system diagram, schematic diagram, calculation, etc., which make the design more efficient. At present, they are widely used in the market, such as Tianzheng and Chen Hao.
Ordinary CAD belongs to a basic CAD platform, which provides the most basic functions. Compared with some professional functions, such as calculation, statistics, rapid layout and so on, the efficiency is relatively low.
Bottom line: professional CAD drawing is efficient, while ordinary CAD drawing is inefficient.
