Rail Clone Tool

WIP
Last modified: 18 March 2025

The Rail Clone command (Multiply > Duplicate > Rail Clone) works just like the Rail Extrude command, however, instead of resulting in an object with a smooth skin, it creates skinless segment clones along the background curve(s).

Rail Clone will create clone or clones of a point, polygon, or object along a curved path (single rail clone) or multiple paths (multiple rail clone). It is nearly identical to the Rail Extrude command. The difference is that Rail Clone creates individual copies of the object instead of forming a continuous skin for the object.

The curve(s) must be in the background layer and the polygons must be cloned in the foreground layer. The orientation and position of the foreground polygons will affect the result. Generally, they should be at the very beginning of the curve and oriented perpendicular to it - as if the curve was a thread you were threading through the polygons.

The direction that the curve faces (which end is considered the beginning) will have bearing on both the shape and direction of the cloning. If you don’t get the results you expect, try flipping the curve’s starting point with **Detail ** > Flip. If you are using multiple curves, they should generally run in the same direction.
