<div dir="ltr">Hi all,<div><br></div><div><br></div><div>Thanks so much for your help guys. As far as Ivo noted I tried the extract cells by region filter and that seems to do the work, only the cells are in 3D - which kinda make sense because my original data is 3D.</div>

</div>We actually have native support for octree datasets - try Sources -><br>
Octree Fractal.<br>
There has been very little use of this dataset and I found that the<br>
reader/writer for<br>
it are not enabled. If you are willing to compile ParaView from<br>
source, I can make<br>
the necessary changes to our development version. Let me know.<br>

<br>
</div>This is the way the slice filter works - it creates triangles rather<br>
than quads. I believe<br>
that there is a filter, somewhere, that generates quads for the case<br>
of (structured<br>
data, planar slice). I'll ask the author of that filter its status.<br>
