However I have noticed that GMSH ( version 4.5.6 ) perfectly read p3d files and exporting them to NASTRAN format bdf, but when tried to convert very same file back to Plot3D format, error message pops up .

Well actually I was wrong, and we do actually already keep track of the structured information in the reader.
// create p3d file
gmsh benchmarks/3d/sphere_in_cube_hexa.geo -3 -o a.p3d
// read it back and save it again
gmsh a.p3d -save -o b.p3d
Works fine with the latest Gmsh.
