Hello everyone!  
I am designing a structural system which is driven by model edges taken from Revit.  
I found this issue with the current model  
-When I create Curve.PointAtParameter I don’t have any points on the end of the curve though I have code Block 0…11…#12. I cannot create a smooth loft surface because the points are not at full length of the nurbs Curve.  
Any clues about this issue?  
Thanks

“Artist”,

Curve parameter values typically range from 0 to 1. Also, see Dynamo Primer about Series shorthand syntax. If you are still having issues you could always try appending Curve.Endpoint points to your list(s).
