Thanks Hans,

I already succeeded to run my file and get 3D panel with the web version. I just had to install the java plugin of iceweasel. This was not part of the standard installation.

I will look later at the local running, but I will give a return.
Bye

I can already use Sweethome through Windoxs 7. I would like to use it through my Linux dist which is the new Debian 8 release (kernel 3.16.2). Using Ubuntu 14 for one app doesn't make sense in my environment.<br/>
I will try again to make sh3d working with ...

<t>When I open a sh3d file with SweetHome 4.5 on Debian Jessie through Gnome 3.14.1, I can only display de 2D panel. Here are the log messages. Who can suggest anything ?<br/>
