Sunlight Hours Analysis Not Working on DWG Import

I’ve imported geometry from Sketchup in DWG format and set up a sunlight hours analysis but I’m not seeing any results. I have used MeshtoNURBS to create polysurfaces from the open mesh. I’ve internalised the data in the attached file.

Hi Chris Buntine


There is only a problem with the open brep that you have put inside “_geometry”. Its normal is wrong. If you flip the open brep, your file works fine.
