thanks, dude but it is not answered…it just returns the z value…I want some things same as line direction

hello, as much on a line your guiding coefficient is constant therefore your normal is constant, as much on an arc (the curvature exists) the guiding coefficient evolves along your arc as well as the normal it must be requested at a point for the arc

You are welcome

PS keep in mind the arcs vector will be from start -end point as the lines…the same as vector by 2 points
