Hi jc, sorry to hear about your harddrive crash - most of us know how frustrating that is...

Unfortunately it's not possible to extract/export models from Lumion scenes for use in 3D modelling applications.
If you import the LS6 files, the imported models will be added to
Documents/Lumion 6/Library but those files can obviously only be used inside Lumion.
Have you tried to run file recovery software, e.g.
Recuvva, or is the harddrive totally dead?
