Which version of Creo View is most compatible with WC 11 M020?
Since WC 11.0 M020 is not yet released and PTC has not made public the 11.0 M020 compatibility matrix there is no way to tell. However it will most likely be Creo View 4.0 F000+. Both are scheduled for a December 2016 release. WC 11.0 M010 requires Creo View 3.1 M010.
