Dear all, I just wanted to let you know that I have been working on a Sketchup plug-in that would allow to define our esp-r projects geometry within Sketchup and export the different zones into .geo files. Right now it is in a pretty early stage, however it eases a lot the process of defining the zones' geometries. I am planning on creating a google code project so that any one interested could test it. I must warn you that, since I have developed this plug-in in my spare time, I have not created any documentation or usage manual yet. Should any one be interested just let me know. Kind regards, -- Nestor Perez
