Thanks for the reply, I wanted to use it in solar array design, thinking maybe it could show real time output with the shade analysis...I haven't done any programming in years, and haven't used ruby ever, but i might have to plug away on it.

Is there a plugin for SketchUp that computes electrical systems voltage, current, resistance? Or maybe a more complex plugin that accepts more variables?

Is there a plugin that will compute electrical systems in SketchUp? either the basic voltage, current, resistance. Or more complex equations, taking more variables into account?
