Update to "Convert Wipeout to Polyline Region"?

[lutzow10]

(Here is a link to the original post I am referencing)

 

Hi Guys,

 

I found this awesome lisp by Renderman/Black Box and I have run it a few times and it worked great those times. Then I tried to run it to convert maybe 20 wipeouts at once and a bunch of them disappeared. I would really like to be able to use this one time once I finish drawing all the wipeouts and not after everyone, but I also don't want to risk some failing to convert and having to redraw a bunch of them.

 

Does anyone see anything that would cause these errors?
