Sengna 11 Posted April 17, 2019 I was wondering will there be any issue later on if i modify the drawing in 2018 solidworks but the file was originally drawing in 2017 solidworks version, someone had informed me that Solidworks if the file is created in 2017 it must be opened in 2017 to edit or work on it. is that true?

GrantW 1 Posted June 3, 2019 Once you save a 2017 file in SW 2018 it will become a 2018 file that cannot be opened in 2017 anymore 1 Quote Share this post Link to post Share on other sites
Sengna 11 Posted June 3, 2019 OK, thank you for reply. wow what's a pain, why solidworks didn't have the feature to save backward like autocad. Quote Share this post Link to post Share on other sites
SuperCAD 13 Posted June 7, 2019 If people are on subscription, there's really no reason to NOT upgrade to a current version. The amount of work that would be needed to make sure that a new feature in 2018 wouldn't break anything when being saved back to 2017 is VERY costly. Given that service pack 5 is basically a light version of the next release, you can use a loophole: "You can open part and assembly files in read-only mode in Service Pack 5 of the previous release."
