I use this software for wiring diagram design, electrical schematic diagrams layout (both 2D & 3D), equipment list of my projects. There are also many features that can be used for data analysis (voltage, current etc.). The price is very reasonable. Some functions could be improved to make it more user-friendly but overall I like its simplicity. This program meets all our needs as we need to have quick access to documents and drawings. It is very easy to use, it works with both 2D and 3D drawings. No other software can do what this one does. We have had no issues with the program. If you are looking for a free electrical design program, then this is the right choice. The price is worth every penny! I would recommend this product to anyone that needs an easy to use, yet powerful software, for designing electrical systems. As of now we are using this software to create wiring diagrams for our home automation system.
