Hello Graeme,
Unfortunately we do not support importing or viewing them directly in OnBase. AutoCAD won't let you open a DWF directly either actually. In order to view a DWF in AutoCAD for example, you need to attach the DWF as an external reference to a DWG. Then when they view the DWG parent, the DWF child will display on the parent. So if you use the OnBase Integration for AutoCAD, you will be able to import DWFs that are attached to DWGs as external references. Then when you view the parent DWG using OnBase, the DWF will display as expected in the parent drawing. However if you try to view the DWF child directly from within OnBase, similarly to AutoCAD it will not display.
To view DWG files (which can have DWF children) you will need the "CAD Services" and "CAD Document Viewer Concurrent Client" licenses.
Thank you for using Community,
Waid
