The string to trim. This can be a mixture of curves, edges, features, sketches, and faces. If features are included then the curves produced by that feature are input as the string to trim or bounding string. If sketches are included then the curves in the sketch are input as the string to trim or the bounding string. If faces are included the edges of the faces are input as the string to trim or the bounding string.
The extension that will be to splines in the string to trim and the bounding string. This should be set to one of the following values: UF_CURVE_EXTEND_NATURAL UF_CURVE_EXTEND_LINEAR UF_CURVE_EXTEND_CIRCULAR UF_CURVE_EXTEND_NONE
Indication of which structure within the union is being used to define how to trim the input string, this should be set to one of the following values: UF_CURVE_TRIM_TO_ONE_BOUND UF_CURVE_TRIM_TO_TWO_BOUND UF_CURVE_TRIM_TO_TOTAL_LENGTH UF_CURVE_TRIM_TO_INCR_LENGTH

mixture of curves, edges, features, sketches,
and faces. If features are included then the
curves produced by that feature are input as
the string to trim or bounding string. If
sketches are included then the curves in the
sketch are input as the string to trim or the
bounding string. If faces are included the
edges of the faces are input as the string to
trim or the bounding string.
