Dear Mario, at the bottom of the page
http://www.lista.it/alibre/alibre_compare.html we compare all the features included in the alibre software versions, including the proof version. if some interesting features for you are not available in the demo version only 32 bits write to us
[email protected] and we will evaluate if you can give you the opportunity to try them for free. I conclude my part contribution (lista studio srl is alibre retailer) indicating the axieme to the eighth row in gallery in
http://www.lista.it/alibre/showcase.html ; by clicking in the image on the left you can download an alibre set with a discreet number of components and evaluate it with the demo version (unless only 32 bits). clearly, being alibre a software with directx and non opengl graphics accelerations, you can get paradoxically better results with cheap computers with 7 view and graphics card for video games rather than with professional workstations dedicated to cad (see the recommendations at the bottom of the
http://www.lista.it/alibre/alibre_sys_req.html ). Finally, regarding the pdm (alibrevault) it is the m-files engine (
http://www.m-files.com ) that is giving us many satisfactions.
