Hi,
Could you describe step by step how to create a 3D
mesh(or structure) from 2D. For example, 3D box from a
2D square? I couldn't find a step by step solution for
this in the manual or elsewhere.

My final aim is to mesh a sphere with hexahedral
elements and this could not be done unless I form the
geometry myself. Using a ready made sphere(from the
menu) and meshing results in a tetrahedral mesh.

Thanks a lot!

To create a box from a square is easy using the copy window:
selection: surface
tranformation: translation (set relative coordinate for second point, e.j
0,0,5.0)
extrude: volume

Then select the square surface and press escape

To learn GiD, download the tutorials from the web page.

Create a sphere to mesh with hexahedral is difficult: GiD only create
hexahedral structured meshes: the sphere volume must contain 6 boundary
surfaces:
See attached sample (you can scale this sample to your desired size).
