Zhao, I just tested facetize with a simple region (see the attached file). Then I wanted to see how many shells it has produced. I thought looking at the ASCII version of the database would be a good idea (created with g2asc). However, the ASCII NMG has always only one shell: rt_nmg_adjust() modifies only the first shell.
Therefore I'm more and more convinced that we don't need the
model-nmgregion structures. Even the work-around with the
combinations may be unnecessary (but I'm not sure).
At least the ASCII import and export should be no problem with the
single-shell nmg. I'ts ASCII format knows only one shell.
Regards,
Daniel
