Just started a project and model was delivered in Revit 2019. Is there a plug in for this?
Are you referring to the iModel plugin for Revit? If so, the current version supports Revit 2016-2018: https://store.bentley.com/en/products/iware/1000IMPR--i-model-plug-in-for-Revit
I am not aware what the schedule is for updating it to Revit 2019.
I've been told there won't be any more i-model exporters for Revit moving forward?
Just as confirmation, we are planning to release another iModel for Revit plugin version - see the thread Mark links to above for more info.
