Hi Luciano, what David is refering to is that "text image" will take your
single file and create a 2D image where intensity (grey) value represent
height (Step 1), starting from that you likely
can use SurfaceJ to create a true 3D representation of your object(s).
(Step 2)
However, as I mentioned in that other post, if one considers a simple fully
convex closed sphere/cell, one will even in the simplest case get TWO z
values for each x and y inside the projection of that
cell (upper and lower surface), the more folded the surface the more
nonunique entries (x,y). Then text import will not work!? Is that the case
with your data?
Mit freundlichen Grüßen / Best regards

I'm going to repeat myself:
File -> Import -> Text Image...
