Value to Geometry Conversion issue.

I'm embarrassed to ask cause I know voronoi is sorta lame, but I can't seem to figure out a solution to convert the area of my voronoi cells which have been sorted and adjust by a 'smaller than' filter back into geometry from data. This is very easy, but I am overlooking something very obvious. 

Also, is it possible to control say, the size of a 3d voronoi cell by setting input domains for different sizes variations? I am working on an architectural program. 

thank you.
