[vtkusers] Is it possible using VTK..??

[Darshan Pai]

I am not sure what you mean by solid boundary and soft boundary .

But when you pick the paticular polyline , you know which prop is that by
say making an ActorCollection and finding the Prop in there . CellPicker has
a GetProp Function. From the Prop you can get your Data back.
