- 4 x Number
- Range
- Integer Slider
- Math.Sin
- Math.RadiansToDegrees
- 2 x Points.ByCoordinates
- Line.ByStartPointEndPoint
- Surface.ByLoft
- ImportInstance.ByGeometries

From the the “Range” *Node* we can get a set of points which will be incorporated to represent the start and end points. As the end points are composing a straight line we will use them as they are. But the start points are composing a Sin wave shaped curve so we need to convert their Y values first to degrees and hence use them as values to the angle input in the “Math.Sin” *Node*.

Once we got the set of start points and end points we will use the “Line.ByStartPointEndPoints” *Node* to create the lines which will be used to create the surface.

The “Surface.ByLoft” *Node* will create the surface based on the supplied lines by lofting. Final step is to import the geometry into Revit and this is done by using the “ImportInstance.ByGeometries” *Node*.
