I want to select a surface from polydata(STL file) and transform(deform?) it. When you select a surface, it is not connected to the existing polydata or the surface is extracted and a hole is created. Is there a way to solve this?

We are going to make some changes, not all of the polydata.
I answered a similar question in the vtkplotter github issues:
