The smoothlines command smooths jagged paths within line-segment models (such as from VTK input) by iteratively moving each vertex a fraction (default 0.1) of the distance toward the average position of itself and its connected neighbors. A single pass through all of the vertices is one iteration, and the default number of iterations N is 10. Overwriting the original model instead of creating a new model is indicated with replace true (default false)
