There called “null lines” since that quantity is,n well, null.</div><div class=""><span class="" style="text-indent: -24px;"><br class=""></span></div><div class=""><span class="" style="text-indent: -24px;"> Here’s my question though. Is there anyway for Paraview to give a value for the width of these null lines shown in the image (red line artificially inserted for now)? Is it through the line object?</span></div><div class=""><br class=""></div><div class=""> One more question - where I have the red line is where I’d like to read off the values. I have other vtk files where the width will change. Is there a way to define this line such that the values change with the width?</div><div class=""><br class=""></div><div class="">Thanks!</div><div class=""> Jesse</div><div class=""> <img height="379" width="640" apple-width="yes" apple-height="yes" apple-inline="yes" id="17942164-4FC3-40A6-8BC3-597B5AF6B23B" src="cid:D3C6CA2F-9623-4C5C-944A-34683A20119D" class=""></div></body></html>
