Change detail to "Fine" to view finer objects

Revit uses multiple settings, like FINE, MEDIUM & COARSE. Currently, we are using MEDIUM mode to export elements and hence some objects may not be extracted for viewing in VR. In order to export them correctly, create a new 3D View with name "Sentio" and set its detail level to "FINE". After that just upload the scenes and you should be able to see it in VR.
