Reverse Curves if start point is higher than end point

I am fairly new to dynamo after giving up the first time. I have multiple curves come from a dwg file inserted into revit, when in dynamo some have higher start points than end points, so i’m trying to reverse only these ones. been trying for hours now. Aim is to insert columns along dwg line, in this instance the columns are slanted, and circular so i have no need worry about rotation. Thanks [Reversing curves that have higher start points than end points] Create Columns from DWG centerlin…
