My settings are the default. “Resolve Coincident Topology” is set to “Shift z-buffer when rendering lines and points”. “Z Shift” is set to 0.002. (Polygon offset should not matter in this mode.) You could try increasing the Z Shift to fix the problem. Note

It is possible that there is some quirk with the rendering system on your computer that does not implement the topology resolution. Do you happen to have another computer on which you can try to run this? I also noted that if I turn on OSPRay rendering, I do
get the missing line issue you describe. There might be other display/rendering parameters that cause issues. But the defaults should be fine, so unless you have done some tinkering you should be OK.<u></u><u></u></p>

I can also see the image you sent; that's usually fine. However, I typically apply a Threshold filter to the _basic_ files (Scalar: alive; min: 0.1; max: 1). In this case, the _basic_ object is always drawn in front of the _broken_joint_ object.

I am unable to replicate your issue in ParaView 5.4.1. When I loaded your data and showed the broken_joint data in wireframe, I was clearly able to see the lines of broken_joint over the polygons of basic. (See the attached image.)<u></u><u></u></p>
<p class="MsoNormal" style="margin-left:.5in">
<u></u><u></u></p>
<p class="MsoNormal" style="margin-left:.5in">
The problem you are getting is likely caused by z-buffer fighting in the rendering. This happens when two objects are the exact same distance from the viewer, as I believe is the case in your data. Wanting to draw lines on top of polygons is common enough that
there are some corrections to help the rendering determine what to draw in front. Perhaps by changing the settings on resolving coincident topology will resolve your issue. You can find them by opening the ParaView settings dialog (Edit → Settings), clicking
on the Render View tab, and turning on the advanced options. The options you are looking for are “Resolve Coincident Topology,” “Polygon Offset Parameters”, and “Z Shift.”<u></u><u></u></p>
<p class="MsoNormal" style="margin-left:.5in">
<u></u><u></u></p>
<p class="MsoNormal" style="margin-left:.5in">
Another, possibly easier, solution it to simply move the lines of the broken_joint data closer to the camera. Click the broken_joint object and add the Transform filter. Change the Translate parameter to 0, 0, 1 and apply. That should shift the wireframe forward
enough to see it properly.<u></u><u></u></p>

I use ParaView to visualize data of our simulations using the Unstructured Grid data format. Up until ParaView 4.x everything worked fine: we typically visualize one set of data files as Surfaces and another as Wireframe. The Wireframe dataset refers to "fracture
