# zLineOfActionUtil¶

For each zFiber node specified, create a NURBS curve that approximates its fiber field. This is an optional helper tool for setting up zLineOfAction nodes to enable automatic muscle firing. In one command, it can create simple curves for every single fiber in a creature. These curves can then be rigged very simply to the joint skeleton and used to make zLineOfAction nodes.

zLineOfActionUtil [flags] [<zFiber_node>...]
-h  -help  <n/a>  this message

Choose one or more fiber nodes by selecting/specifying a mesh with zFiber
nodes on it, or the zFiber nodes themselves.

This command will create a NURBS curve that approximately follows the muscle
fiber field. The result is an array of curveName-fiberName pairs,
with each created curve listed before the fiber that it goes with.
