<div>Hi T.J.,</div>
<div> </div>
<div>I have just tested your branch - unfortunally it still doesn't work. Before appending the two meshes, both are manifold and everything seems perfect but after appending a lot of cells are not manifold anymore... . I still don't have a suitable solution...</div>
<div> </div>
<div>Best regards</div>

<div>Hi Maximilian,</div>
<div> </div>
<div>I have just recently worked on making the output from vtkBooleanOperationPolyDataFilter more robust to numerical errors implicit in the Delaunay2D algorithm. Would you mind trying <a href="https://gitlab.kitware.com/vtk/vtk/merge_requests/3273" target="_blank">this branch</a> and seeing if it helps?</div>
<div> </div>
<div>Sincerely,</div>
<div>T.J.</div>

<div>Hi everyone,</div>
<div> </div>
<div>I'm struggling with the vtkBooleanOperationPolyDataFilter. First, I'm computing the difference D between two vtkPolyData objects, say A and B (this is D := {A\B}). After that, I want to append the resulting difference D to B, i.e. make the union of these two meshes. Therefore, I'm using the vtkAppendPolyData filter. However, the final result is not manifold (which is necessary in order to print the mesh). I also tried the vtkBooleanOperationPolyDataFilter with the union operation but the problem still remains - the final result is not manifold and therefore not printable. How can I append these two meshes so that these are manifold and thus watertight (and printable)?</div>
<div>
<p><span>Any help would be appreciated. Thanks!</span></p>
