Hi,
I think you're talking about Energy3D that has no compiled Linux version. The SH3D plugin is no OS-dependant if I tested well (I have no MacOS for that...).
Well I compiled and tested only windows version (that's what I have in schools I work), and the source tells that it is compatible...if someoone could elp me test on another OS, feel free. Thanks for helping.
A plugin for house's analyzing is much far compilcated than just converting for another tool...but I can change the plugin to embed Energy3D now that building conversion works.
