I have problem with solidworks toolbox. I had Solidworks 2011 on my pc and I unistalled it and install version 2012 on pc. So I've created many square tube with version 2011 for example 70x70x3.2*1000 , but know when I open assembly in 2012 version it changes to "square tube_iso". how can I fix this problem? Because I can not replace each part with right one.

thanks a lot
