If the new structure is sufficiently well matched to the old one when
they are in the default (untransformed) positions, then after you
reset to the various positions, you can bring the new one in by
applying the same transform as is used for the older similar structure.
For example, if your older similar structure is model 3 and the newer
one is model 10, and you have just reset to a position that leaves the
new model stranded, try the command
matrixcopy 3 10
to bring 10 into the proper position.
How "reset" dealt with new models not in the original saved position
was improved (after release 1.3) so that the new models will maintain
their transformation relative to the lowest-numbered model that was
included in the position. I guess your older similar model is not the
lowest-numbered. Or, if it is, you could try using a recent daily
I hope this helps,
