Building Pads dynamo

I have a problem when trying to create construction platforms with dynamo and phyton, under structural elements, could you help me to solve the error please?

hello, curveloop.Append not append
append is from python, while Append is from curveloop method

Also, I believe you’ll need to transform your Dynamo polycurves into Revit curves. Explode them and then use the ToRevitType() method to do so.
