给你找了一下用这个：

UF_PARAM_replay_path (view source)


Defined in: uf_param.h


Overview

This function replays the tool path for the operations associated with
the object specified by 'param_tag'. If this object is a group then the tool
paths for all operations in the group will be replayed. If the object is an
operation then the tool path for that single operation will be replayed.
