Problemas opening files SolidWorks 2012
Hi guys, I study at senai and we use SolidWorks 2011 there.
Yesterday i came home and wanted to show my parents the work i did.
The problem is, at home, i used solidworks 2012, and overwrote my original files.
Today, i went back to senai, and i couldn't open any file, it said it is a future version or something like that.
I asked my teacher, he told me to go back home and save my files under the format ".igs".
I did that but when i opened it, i couldn't see all the steps i had made. So now if i want to modify something, i have to start all over again.
Does anyone have a solution for my problem? Like a program that converts to SW2011, or should i sabe in another format?
Sorry for the bad english. Long time no use.
Thanks for the time!
