Hi I spoke with the local reseller and the offer will be available until Aug. 31. As well as I tried the software , rhino import as well and that was working but I have some big 3DM file (120MB) what were thrown by Alibre Design I have got memory probleme too. So I could not use the software I tried with simple shapes like Sphere and so on and thats work. But the conclusion the Alibre interface is horrible after Moi or Rhino or etc. maybe enough for mechaical design but not for product designer. Very easy to use make holes and any exact modfication but finally I didnt buy despite documentation and print part is very inteligent and promising and there are some engeneering tools what is suitable to define volumes(m3), weight(kg), area (m2).
