[Paraview] SWKey: How to Clean-up an STL datum set?

[Samuel Key]

Hello All,

I am working with a less than perfect STL surface. I was able to use 
PV's Clip filter spheres to remove a number of spatially isolated 
undesirable triangle clusters.  (With a new application of the Extract 
Surface Filter, I was able to use Save Data to get an updated/revised 
STL file.)

I am now working on removing triangles that have a point or an edge 
attached like a fish fin to the desired STL surface. I have successfully 
selected the undesirable fin-like triangles. Now, I want to delete (or 
Clip) these triangles to remove  them from the datum set. Right-click 
delete does not appear to be an option?

Is there some way to delete these selected STL triangles from the Datum set?

Regards,
