Hi
Looking at the screenshot of Revit Lookup provided, isnt it possible to iterate through each of the Panels returned and check if the panel is a wall type. If it is, then access the Id of the wall?
Or if you look up the DB of the RevitLookUp, does this wall get listed under the Wall Elements listing from the model. If it does, then you can directly find out the wall id from the wall in the model. But this is only helpful if we assume that the model would not have any other walls other than the ones what are part of the panels list.
I would think the first approach is better and something to consider. Are there any specific problems with this approach (Panels-> Wall).
cheers
