Hi, I’m a student and I’m pretty new to dynamo.

I’m trying to make a script that can read parameters from a Excel file and then create those parameters in Revit. The goal of the script is to make lots of parameters really fast to save time.

I can’t seem to find a good way to convert my “Instance/Type” column from Excel to a boolean output that the “instance” node accepts. I’ve tried to search around for a solution but I cant seem to get it to work. Any help would be appreciated 🙂

Maybe spend some time in the Dynamo primer? It’s a great way to learn techniques like this 🙂

Best of luck,

Mark
