hello


i am answering myself as nobody seems to be interested in that
problem!!!

i may help someone

I have found the following sequence does the job if inserted in the text
(.geo) file


Physical Line("potgc") = {582, 473, 460, 447, 434, 421, 414, 420, 432,
445, 458, 471, 484, 583};

Physical Line("potgc285") = {Rotate {{0, 0, 1}, {0, 0, 0}, -Pi/2} {
 Duplicata { Line{582, 473, 460, 447, 434, 421, 414, 420, 432, 445, 458,
471, 484, 583}; }
}};

quite easy with cut and paste and then mixing the groups if necessary

that's quite useful in construction job of frame structures with many
translations, rotations and or symmetry

i may help someone!!
