poly extrude : Extrusion mode - Point Normal - Attribute - "pexN"

I couldn't reproduce your method - any suggestion??

PS
I just begin to learn houdini

The input box does not need to be green. You should (Ctrl + Shift + Left Click) on this input box to make it black

The input content is "pexN", not "@pexN", I use pexN instead of N just to not occupy N, because the original N will still be useful in the future and I don't want to overwrite the value

"poly frame" ,"orientalongcurve" ,"normal" nodes can control normal direction

For your current needs, using Vex to control normal is better

point wrangle after remesh1
```
v@pexN = {0,-1,0};
```

and then
poly extrude : Extrusion mode - Point Normal - Attribute - "pexN"
