| Hello Karsten, 
Thank you for your help, it works perfectly.
 
To use the curve segments as discreet sweep rails, 
it was necessary to alter your Construct2/Sweep node 
changing processInOut to "Long" as shown below.
 
Nodes/Extensions/contruct2.js   LINE 62 
var data = this.processInOut("Long", this.multiProcess, null, null);
 
Will this adversely effect its functionality?
   
Hi Brian, 
<<Curve node may be used instead of polyline.>>
 
Yes, polyline was only a stand in for the purpose of clarity. 
Also, Points/InterpPts node before curve node gives a more pleasing result at thread ends.
 
Keep on Noding
