I think, that the problem is...in the version of web Sweet home, because the web Sweet home version which I use is 2.3, so I think here is a problem. Web version which I use is on the one of ours web page: [url=http://]http://dominvrt.si/spletni_arhitekt[/url] ... and that is a problem! I don't have the option to export SH3D format.
