Hello,
I'm new in Houdini. VERY new
So its my first post and first question.
From what I know Point-Old SOP is something we should avoid.
But in tutorial I'm watching now I can see that old Point SOP is used to generate normals using Edge Force.
This normals is used to orient copied elements along spline
How can I get such functionality with VEX expression and new Attribute Expression SOP?

sorry for my English

I assume you're trying to get normals pointed along a curve by using edge_dir as your N attribute?

1. Place down a polyframe node
   
2. Style = First Edge
   
3. Tangent Name = N
   
4. Other parameters off
   
5. insert a reverse sop before the polyframe to make the attribute face the direction you want
