Am I using the node wrong? Dynamo v2.0.3
We have to see more of your script. That node only works with surfaces originally derived from Revit faces.
It’s for dimensioning walls with a model line as reference, I took it from the explanation of @viktor_kuzev in this post back in 2016: Automatic Dimension Walls
right, don’t have time right now, but could you check if maybe deriving the faces from the topology works better than through polysurfaces? have a look at the script in the link you provided.

The thing is topology faces node wasn’t working for me, so I used this method.
Try using Element.Faces to get the surfaces
