So basically I just want to push the stairs in the direction of the curve. Attached is the example project.

Hi,

You can compute the tangent using the Resample SOP without resampling or the Orientation Along Curve SOP and then use this VEX code in a Point Wrangle:

@P += v@tangentu * ch("amount");

Gotcha! I totally did that with the Orientation Along Curve SOP just out of order - In my original case I was trying to do this after the Assemble node with packed primitives and using a @P = point(1, "tangentu", @ptnum); rather than right after the resample node! Totally works! Thank you so much!
