Hello,
1) how can I share the file?
2) I don't think it depends on the file since sometimes (very rarely) it displays all the walls and furnitures right. Sometimes it's enought to open and close the application 20 or 25 times and then, like a wonder, it works......

Hello all,
I was using Sweet Home 3D on other PC with WIndows 7 and never had this issue. It renders the 3D preview with many errors in the geometry. Any idea n how to solve it? Sometimes it works well but most of the times it displays like in attachment.

Thanks!
