In order to make it easier for everyone to understand the Sfere720 related series, we have updated the EPLAN project files of Sfere720 and its supporting modules on EPLAN software. You can download the files if you need.
EPLAN, an intelligent design tool in electrical design field. The software is specially designed for electrical design, drawing electrical drawings is very fast, and the software itself supports electrical symbols, which is easy to insert. After the drawing is completed, it can directly generate many types of reports, such as cover, catalog, terminal table, component table, etc.
