The problem I was having is that I was planning and trying to use a polygon. It seems that if you try to use that Slice Along Polyline, but select a polygon for the input, it crashes paraview (it should probably bring up an error, or only allow a polyline!). I realized that it actually wants a polyline, and once I created one for my region, the filter does what I had been looking for. But, that leads to another question… If I want a whole region to be another color, is there a way to fill the output of SliceAlongPolyLine? So, instead of just an outline, I can get the inside to also be a certain color?
Thanks for the help. -- Adam On 10/26/16, 10:10 AM, "Adam Dershowitz" <adershow...@exponent.com> wrote: I tried it a few times, and it kept crashing Paraview. So, then I read up on, it and seemed, from the description, that it was not what I wanted anyway. But, if you think it is, I will see if I can get it to work. -- Adam On 10/26/16, 1:01 AM, "postgu...@web.de" <postgu...@web.de> wrote: >Adam, > >Have you actually tried the filter?
