when I try to make RFT. by using node (by curve) from structural design page its give me this error
What does the warning say?
What Package is that node from?
Curves are not my strong suit, but i see @jacob.small is already coming to the rescue.
When you get an error message like this, look at what it is saying carefully. Map out the ‘expects’ against the ‘called with’.
Expects : called with
a Dynamo Curve : list of Dynamo Polycurves
a string : a string
a Revit element : a Revit element type
a Revit element : a Revit element type
a Revit element : a Revit element type
a string : a string
a string : a string
a Revit element : a Revit framing element
a Dynamo vector : a function
Notice I added some highlights on the list of polycurves (your first input) and your function (last input) as the former might be incorrect, but the latter is absolutely incorrect. My guess is your Vector.Z wants to be Vector.ZAxis, but I am not sure.
