I'll be really glad to help.

Wojciech, I can send you a GH-Ecotect interface script - I was writing a plugin but unfortunately Ecotect support is pretty much non-existent and it was impossible to get something running smoothly between the two. The script takes input surfaces and exports them out as GB_XML elements and written as an XML file, the file is then called into Ecotect via a sendkeys call using LUA (ecotects scripting enviro). LUA can then be scripted to call simulation routines with the data then sent out as an XML or txt document which GH can be streaming for updates.

Give me your email address and I'll send through the script.
