Please Note - This message only appears in v3.6 of the plugin. We highly recommend updating your plugin to the latest version which you access via this link: NBS Plug-in for Autodesk Revit – NBS National BIM Library
When signing into the NBS plugin for Autodesk Revit as a Lattira Spec or NBS Chorus user, you may receive a message saying the following: 'Your NBS ID does not have a NBS Create Licence associated with it. You can continue to use the NBS plug-in, but some functionality requires an NBS Create Licence to work. This functionality includes viewing the NBS Create Guidance and associating objects with NBS Create office masters.'
This message indicates that you don't have a NBS Create subscription, however, since you are using NBS Chorus this message is irrelevant and will not affect the functionality of the plugin.
This is more of an alert than a warning, and expected behaviour to check if there is an NBS Create licence attached to the NBS ID when logging in.
