So I’m trying to isolate in Dynamo all materials in Revit where the Material: As Paint parameter is “yes”. Then I’m going to create something along the lines of if Material: As Paint parameter is yes, I want the Accent Paint (a custom wall instance parameter) = Material Name. If it’s no I want it to stay blank. The problem I’m having is trying to filter my list in Dynamo by the yes/no. I’ve tried “Yes” “1” “True” and nothing seems to work to pick up the correct output. They all show as false even though 1 of the values should be showing up as true. Bare with me because I am relatively new to Dynamo.
