We normally use Inventor, R2011, but we have a client we've done a major project for who uses SW probably R2013. We did the engineering and design and sent it to them in .stp format. Now they want us to quote a drawings package. Is it possible to convert drawings (and associated models) from Iv R2011 to SW R2013? We have 2 seats of SW R2010 which we could use, but we only have one full-time drafter who knows SolidWorks. We're concerned we can't meet the time frame. Also, I read that SW R2013 is not Windows XP compatible. Is that true? Thanx for your help.
