That's right: every time you merge a view, gmsh recomputes the bounding
box of the scene.

To override this bounding box, you can use the following command in
one of your files

BoundingBox{xmin,xmax,ymin,ymax,zmin,zmax};

 From then on gmsh will use this bounding box, until it sees the same
command without arguments (which will force the recomputation of the 
bounding box based on whatever models/meshes/views are loaded):

BoundingBox;

Warning: these commands are actually broken in gmsh 1.60... You will
need to download and compile the latest nightly cvs source snapshot
(http://geuz.org/gmsh/src/gmsh-nightly-source.tgz) to get it to work as
described above.
