Sounds like boolean operations, see this:

> I’m looking for a way to do boolean operations between two STLs in Paraview. Unions, Differences, etc… This is unfortunately for a compute environment that doesn’t have Meshlab, Blender, etc…, but it DOES have Paraview. I’ve looked around and it seems that there’s not a way to do this directly, but maybe it can be done with a script? Does anybody have experience with this? Thanks. -David O.

Not only append, but really intersection, union, difference. Related : [Boolean Operations - #9 by RR84](https://discourse.paraview.org/t/boolean-operations/1498/9)
