Hi,
I have never needed this functionality myself. However patches are
certainly welcome. If you really need this, have a look at line 246
of file ov-netcdf.cc. You would need to add a special case for ncdim:
else if (args(0).class_name() == "ncdim") {
// do something
}
and add the line 'dispatch('var','ncvar','ncdim');' to PKG_ADD.
