Geco import problem

Hi all,

I am trying to import rhino geometry to ecotect through geco, then take the information back into grasshopper to do further operations. I have been successfully doing that in simpler geometries but not in the particular rhino file attached- the lighting calculation fails to import the data back into grasshopper after ecotect finishes calculating daylight factor.

any help will be greatly appreciated!

thanks!
