unable to convert plan to .svg using sweerhome3d 6.5.2 on centos 7

Hi

System Info
-------------

Code: Select all

$ cat /etc/centos-release
CentOS Linux release 7.6.1810 (Core)

Code: Select all

$ uname -a

I downloaded SweetHome3D.jnlp and used the command:

Code: Select all

$ javaws SweetHome3D.jnlp

to open it.

This seemed to work OK, but when I open a .sh3d file and try to convert it to svg format by going to:

Code: Select all

Plan->Export to SVG format ...

It does not do anything. "Export to SVG format ..." does not highlight.

If I install the same sweet home version on a windows 10 machine I can export to .svg fine.

Would anyone have any idea why this might not work on a centos 7 machine ?
Is this the correct way to run swwet home on linux (using the .jnlp file), or do I need to download a different file ?

Ok. Initially I was running as root which it seems did enough to open the app, but when I tried running as a normal user it was unable to start - various exceptions thrown by java, so I guess javaws is not the way to go. (Not really sure what javaws is, but it looked like it was trying to run using a web browser).

I've installed snap and will try to install sweethome using that.

Why not trying the official version available at SourceForge.net?
It contains two scripts to launch Sweet Home 3D: [font=courier new]SweetHome3D[/font] and [font=courier new]SweetHome3D-Java3D-1_5_2[/font] which should work if the first one doesn't.
