From the developer:
Elwin is a software tool for designing electrical circuit diagrams with special direction on automation projects. The software suits both advanced designing by engineers as to more simple circuit diagrams by electricians.
Elwin is a databased CAE/CAD system, which means all graphics, text and data is pre-defined in a database. When editing a circuit diagram the user selects objects from the database and only specifies the object properties.
You may want to check out more software, such as Smart Map, stCAD or eDrawings for SketchUp, which might be similar to Elwin.
