Where could i download autocad 2008 or any version for free?
The best legal option would be to join Autodesk’s Student Engineering and Design Community. Its free, and you have access to year-long versions of almost all of Autodesk’s software, ranging from plain AutoCAD, to Revit Architecture, to Civil 3D. Technically, you’re supposed to have a school email, or that of a teacher, but I think you could get away without one.
