I have uploaded an image of the simplified definition that is causing
problems.  I have one 4-pt planar surface BRep.  I am wanting to
extract the wireframe and split the four line-like curves in half.  I
measure the length and plug in the half-length into the CrvShatter
component parameter (t).  I have four curves, and four (t) values.
The component fails, turns red, and outputs 10 line-like curves.

Incidentally the curves that DO shatter comprise two out of the four
lines, and if I join some of the segments I can get two halves of each
of these two lines (meaning that at some point the component is
splitting the curves at the halfway point).

However I would expect eight lines, the four split cleanly at the
middle.

Am I doing something wrong or is this a component problem?

Thanks,
Marc
