As a part of a quality check, I want to list the IDs of those elements which have not Material in the model. I extracted the Material and IDs of all elements and did some filtering as shown in the below picture. At the end, I used List.Transpose to show me the IDs which have no Material, but the list also contains the IDs which have Material too. Would you please tell me how I can filter only the IDs which have no Material (as highlighted in the pic) from the list ?
I am gonna send only the list of IDs which have no Material to Excel, not all the IDs.
Thank you so much in advance
