Dynamo surface vs. Revit Surface - node: RevitFaceReference.FromDynamoSurface

[Thomas_Corrie]

RevitFaceReference.FromDynamoSurface will only return a RevitFaceReference if there is a Revit face underlying the Dynamo surface, not if the Dynamo surface has been created independently:

Clockwork RevitFaceReference.FromDynamoSurface returns null

You just created that face from scratch. It does not have a Revit equivalent inside the model. That node works only for faces selected with the built-in “Select Face(s)” node.
