Setup Information:

Running SweetHome3D on Ubuntu_20.04 and Ubuntu_20.10 with Nvidia GEFORCE GTX1060 with following setup:

  • export JAVA_TOOL_OPTIONS="-Dcom.eteks.sweethome3d.j3d.useOffScreen3DView=true"


  • Opening a bigger SweetHome3D project in the SweetHome3D GUI results in crashes like the error message is showing above. 


  • Directly open SweetHome3D from command line with the project to open attached as argument to the command. Now SweetHome3D should properly open your project without issues.


~/Path/To/SweetHome3D ~/Path/To/Project2Open/projectname.sh3d


We did use SweetHome3D for various projects in the past. Right now we are building a datacenter located in the Alps Austria/Europe with the power of SweetHome3D for draft submissions to our construction architect.


SweetHome3D thanks for everything.
