is there a function to resample a polyline same as the resample node?
that can give options of putting n points or putting every distance?

thanks guys

I have the same question

There is no such function. Depending on what kind of resampling you want to do: resampling NURBS, Bezier curves, resampling using subdivision interpolation, or resampling using polygon edges, using point count or division size, resampling based on curvature, etc, you need to write the code yourself.
