I am using space.volume to get volume of a space. There is marked difference between the volume returned by space.volume and volume returned by sketch up. I have gone through previous questions in the forum. My geometry seems to be ok but it would be great to have a check. I load by model in sketch up and the plugin doesn't throw any reverse face warning messages. I have also rendered the model by Surface Normal and the whole model is white from the exterior. I have a very simple model with a zone and hip roof. The volume of the zone is right but volume of roof is incorrect.
Please find the model attached and also screen shot below
.
I am also providing the OSM file if anybody is interested in loading it up in sketchup. Please let me know, I can send it to you.
Sketch up value of volume - 7.33 cubic metre but space.volume gives me 8.57.
