I’m trying to extract Door-Room information from Revit to Excel. I’m getting an error ‘Warning: Internal error, please report: Dereferencing a non-pointer’ from the ‘fromRoom’ ‘Room.Number’ & ‘Room.Name’. I think it maybe because the external doors don’t have a Room from (as it’s working fine with to Room).
Can anybody help? I’m fairly new to Dynamo and I need this in a panic for my final year college project. I suspect I need to put an ‘if’ condition in to tell it to replace an empty value with a specified value…?? How would I do that though?
