Dynamo custom node

Hi All,

I have created a custom node. which creates multiple instance of a family based on different dimensions in excel and takes rotation and start point of detail line selected in Revit. everything is working fine.

problem is if i select these detail line one by one it works fine however if i select multiple line it does not work. what should i do so that it will start again for next detail line.

It’s probably an issue with list lengths/structure. Try using list levels.
