There's no way to "move an edge". You can change the edge shape but start and end nodes must stay the same. > and after this remove the external edge of F2 > > +---------+ > | | > => | F1 e > | | > +---------+ > > Is this allowed ? If your goal is to turn T1 onto taking the whole space of F1 and F2 you should just add F2 to the definition of T1. No need to drop any edge. --strk; ,------o-. | __/ | Delivering high quality PostGIS 2.0 ! | / 2.0 | http://strk.keybit.net - http://vizzuality.com `-o------' _______________________________________________ postgis-users mailing list postgis-users@postgis.refractions.net http://postgis.refractions.net/mailman/listinfo/postgis-users
