<div dir="ltr"><div><div>Hi Aleksejs,<br><br></div>Welcome to the ParaView mailing list. <br><br>This appears to be a bug that you've found. In case you didn't notice, for the unstructured grid there are 4 triangle cells that connect to look like a tet. I've added a Mantis issue at <a href="http://www.paraview.org/Bug/view.php?id=15040">http://www.paraview.org/Bug/view.php?id=15040</a>.<br><br></div>Thanks,<br>Andy<br></div><div class="gmail_extra"><br><div class="gmail_quote">On Thu, Oct 9, 2014 at 5:33 AM, Aleksejs Fomins <span dir="ltr"><<a href="mailto:aleksejs.fomins@lspr.ch" target="_blank">aleksejs.fomins@lspr.ch</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Dear Paraview,<br>
<br>
I am new to this list, so I would like to immediately apologise if my<br>
style does not meet your standard.<br>
<br>
I am learning to use Paraview, and I have problems using the threshold<br>
filter. I have attached 2 .vtk files based on documentation examples to<br>
explain my point<br>
<br>
I use filters->common->threshold, then specify Scalars->cell_scalars<br>
and choose range [1,3].<br>
<br>
* For the "polydata.vtk" I observe some of the rectangles disappear as<br>
expected. If I manipulate the range, I can get any one rectangle disappear.<br>
<br>
* For the "unstructured.vtk" I see all but one triangle disappear, which<br>
is unexpected. If I manipulate the range, either the tetrahedron<br>
disappears altogether, or only one triangle is visible.<br>
<br>
Could you please tell me what am I doing wrong?<br>
