String doesn't get parameter

Hi everyone,

I’m trying to connect Revit to Excel and it was supposed to be very easy and simple, but the string node is not connecting to the parameter I need… The watch node doesn’t show anything :frowning: what am I doing wrong ?




Thanks a lot

The problem you’re having is that Description and Type Mark are type parameters so they’re handled a little different in Dynamo. You need to feed the node an element type to extract it’s type parameter rather than individual elements to extract instance parameters. Below is a couple different ways to achieve this, both use a custom node from the rhythm package.

Type Param



I got it, but now how do I connect those data to the excel file I’m trying to create? Because using the Element Set Parameter By Name there is a connection between the parameter and the lists, but using the rhythm node there isn’t…


Thanks :confused:
