Hi Dave,
Thanks for the prompt reply.
So to STL mesh is determined by whatever created the STL model?.
Unfortunately, yes.
If I remember well , there was an EXPERIMENTAL STL remesher in the rather old 1.65 version (
http://geuz.org/gmsh/bin/Windows/gmsh-1.65.0-Windows.zip)

Cheers,

Hi Mike,
from: http://www.geuz.org/pipermail/gmsh/2008/003744.html
...
Gmsh will not remesh these STL faces, though. It's something we will
reintroduce at some point, but the remesher is not ready yet.
...
Cheers,
Dave
