The Normalize Spline modifier adds new control points in the spline at regular intervals. Use Normalize Spline to produce splines for motion paths that require constant velocity.
The spline on the left has been normalized.
Sets the length of the spline's segments, in 3ds Max units. The positions of the original vertices are discarded, and vertices are set to regular intervals. Segment length determines how many control points are added: shorter segments result in more control points, longer segments result in fewer. Default=20.0 units.
