We had customized styles in Inventor 12 Then installed 13 and had some conflicts using the 12 styles. The person who customized the styles is no longer with us so I dont know what all was changed. Our work stations point to a styles network location so we are all on the same page. I would like to know if there is a way to compare the default styles to the custom files so I know what was changed. Then I would keep a log book of style changes as they occur and update the style of the next release b4 company wide installation. Or perhaps there is a better way??
