I need to place my families in Revit model in same point and orientation on wall. Where my linked file shows the points where I need to place those family . I get the points from from my linked files and tried to put it with FamilyInstance.ByFace, why By Face because its an electric fixture which can be mounted on any of the surface of wall, So i need to exact orientation and location to place my family by face. But unfortunately getting the point from linked file and the wall making a bit complicated. I could have share my dynamo but its not worth it as its become a mess of nodes.
I want to take or start step by step, any guidance and help would be really appreciated.
Here’s a sample image on my model , i need to place a my new family in the same location.
