You can apply vtkTubeFilter to the output of vtkClipClosedSurface. This will generate a new dataset with just the lines, where each line is thickened to form a tube.

Thank you @dgobbi for replying. I am looking for outline(different color than cut surface) along with faces as an output of vtkClipClosedSurface. Whatever the clipcolor I set, that is being taken as outline color as well. For that I had to subclass and set the different color to the outline. Is there anyway to set the outline color without subclassing?
Tubefilter gives me thickened outline but I have to run the vtkClipClosedSurface filter 2 times(with generateFacesOn and Off).
If the dataset is big, then running the filter 2 times adds some extra time on the performance I guess.
Thank you.

No, vtkClipClosedSurface cannot set a different color for the outline. But VTK has other ways of setting colors, for example in the property of the actor:
```auto
// tell the mapper to ignore scalars on the data
mapper->ScalarVisibilityOff();
// set the actor to use a specific color
actor->GetProperty()->SetColor(1.0, 0.0, 0.0);
```
So, if you have an actor with only lines, you can control its property independent of the faces.
```auto
// create a new data set with only lines
auto lineData = vtkSmartPointer::New();
lineData->SetPoints(clip1->GetOutput()->GetPoints());
lineData->SetLines(clip1->GetOutput()->GetLines());
lineData->BuildLinks();
```
So, you only have to execute vtkClipClosedSurface once. Note that vtkTubeFilter will also extract only the lines from the output, which is why I recommended it (also because you asked for thicker lines).
```auto
// stripper will improve the result of vtkTubeFilter
auto stripper = vtkSmartPointer::New();
stripper->SetInputData(clip1->GetOutput());
stripper->Update();
auto tube = vtkSmartPointer::New();
tube->SetInputData(stripper->GetOutput());
tube->SetRadius(0.01);
tube->SetNumberOfSides(11);
tube->Update();
```
That is my recommendation. Do not use `clip1->SetScalarModeToColors()`, instead use the actors to set the color. And of course, do not execute vtkClipClosedSurface twice.

I got it. Thank you very much @dgobbi . I appreciate your help. This works well for me.
