Recommendation

Here is an easy way to get internal coordinates, which should work.

Have coord ready before calling define. In the main geometry menu proceed as follows to define redundant internals:

a coord
read coord
desy
determine symmetry, if you expect a higher symmetry, repeat with increased tolerance desy 0.1 , you may go up to desy 1..
ired
get redundant internals
*
quit main geometry menu

To define internals:

a coord
read coord
desy
determine symmetry
i
go to internal coordinate menu
iaut
automatic assignment of bends etc.
q
to quit bond analysis
imet
to get the metric, unnecessary internals are marked d now. If #ideg = #k in the head line you are done. Otherwise this did not work.
<enter>
go back to main geometry menu
*
quit main geometry menu

To define cartesians:

a coord
read coord
desy
determine symmetry
*
quit main geometry menu
