Hello,
I am student near graduation and I´d write my diploma work about 3D modelling and intergrating 3D models into GIS (arcGIS 9.x) environment. IM demo is cool, I´ve learnt a lot about working in it, but it  disables to save projects, nor exporting finished models. I would like to ask, if there is something like "IM for students" to share? Thanx for replying....
