Also, under options->mesh, there is an important difference between surface/volume mesh visibilities.

PS:

1) all the mesh formats supported by Gmsh are "3D"

2) the p3d format is actually *not* supported anymore (use Gmsh 2.0!)

3) there's a little script in the source distribution (in the
utils/converters/matlab directory) that reads .msh (version 1) files 
directly into Matlab.
