Floor Coordinates Excel Import fails

Hi guys,

I am new to Dynamo. I got some help from helpful People here to create a script, that Export coordinates of a floor to Excel and then you could Change them. I set the coordinates to N/S and E/W, Export works perfectly but Import Fails on PolyCurve.ByPoints. What should I do at that Point?Excel_FloorV2.dyn (33.5 KB)
