Have a look again at @salvatoredragotta post because he is putting in a revit element pattern, not a string text from excel and also they have converted the numbers for the colours into a colour element.
So for the line pattern and colour, you will need to do the following two things:
Find and get the line pattern that matches the name in the excel file.
Convert the 3 colour rgb numbers into a colour for input.
Once you have these then you should be fine and the thing should run.
@Alban_de_Chasteigner your RGB procedure is more easier. Thanks you very much for your help about Line Pattern.
Question - “HOT Gear” Node not able to identify the Solid Line,
@Alban_de_Chasteigner , @salvatoredragotta please try to create a solid line in this same node. I am getting the massage “null” instead of Line Pattern.
