The SimLab Composer exporter lets you publish 3D models straight from SimLab to Sketchfab.
As of SimLab Composer 6.1.7, the Sketchfab exporter is natively integrated! As long as you have the latest version, you can already export your models directly from SimLab Composer.
When the upload is complete, you can view your model on Sketchfab, adjust rendering settings, and save the default view.
