### Usage:

**smoothlines**
*model-spec*
[ **stepFactor** *fraction* ]
[ **iterations** *N* ]
[ **replace** true | **false** ]

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**)
