good morning there is educational version but can not be used to how much I am for commercial purposes, example design study, can be used for training teachers and students of second-order schools and universities find information on this page: http://www.solidworks.it/sw/education/3d-student-design-software.htm Have a good day.
exactly you can not use for commercial purposes the student.
If you want something that does little, you must uninstall the modules that you do not use. above all you must not load the additional modules in the swx options.
what weighs are the files of libraries, toolboxes and tutorials.
By taking those off, I think you'd get 1.5 gb of stuff.
However, it is not the installation that weighs down your hd, since now they give you a minimum of 120 gb, it is the music you download :smile:
