I made the nodes to make points for curve.  
And points are good but it didn’t draw the curve.

pls show us the outputs from point.bycoordinates

How big are your coordinates?  
Maybe your workspace is to small for them.  
Dynamo/settings/workspace for geometrie

It is hard to tell, do you think you have any points which are coincident? I would try pruning for duplicate points first or measuring distance between every point as a debugging step.

You could also try nurbsCurve.byPoints instead of polyCurve to start.

Posting the dyn and any referenced files to another file share (say google drive) would also help here.
