[Paraview] Extracting an irregular surface

[Hedieh Ebrahimi]

Hi,

I have a question. I have two different csv files, both representing
surfaces of an area.
These two csv files consist of  "X","Y","Z"  values,
after opening these csv files in paraview and applying the following
filters on each,

/CSV File
1.Table to Points
2. Delunay 2D

I  will get a surface for each of them with one being a subset of the
other. The problem is one of these csv files has more points and represents
a bigger area and will end up to the higher resolution surface. These are
range of x,y values for the two csv files:

1.csv File with more points showing a bigger area

X=[-6000,24000]
Y=[-7000,23000]

2.csv File with less points showing smaller area

X=[1152,14336]
Y=[1408,17024]

Is there any way I can extract from the bigger csv file the area related to
the smaller file ?

I know I can extract from the bigger file the limits of the smaller one?
but the area I am interested in has an irregular shape and I don´t want to
be simply exporting a rectangle.

Is there anyway to do this in paraview?

I hope I´m being clear in my explanation.

Thanks
Hedie
