Please extend your time, regarding Sketchup to ecotect

[Anonymous]

Hello All,

               I tried to do the analysis for a very simple Model which I imported from Sketchup in a .DXF format, 

Model: - just a four walls, covered roof with no windows, (Just for analysis)

when I applied the daylight analysis, surprisingly the Grid shows total yellow box, means a good Light!!,.

I dont know how it showing with out windows,

Attached ecotect zip File,

Kindly Please extend your time to leave the guide comments, how to import properly, 

Sorry for my English,

Thanks for your considerations,
