After upgrading from 2017 to 2018 I have noticed all my custom materials have disappeared.
How do I get them back
(SolidWorks 2018 sp0)
Where were your custom material files saved? If they were saved in the SW installation folders they may have gone poof when you upgraded. If they were saved somewhere else are you still pointing to that location at Tools > Options > File Locations > Material Databases?
Looks like I saved them to the insolation folders and they have gone when I up-graded.
Not to worry I had just finished adding some of them back in them back in.
