Allora ecco una possibile soluzione:
faccio tutto il disegno con Dia e poi lo esporto come Macro tex pstricks
Poi apro il file e lo copio nel mio file. Funziona bene solo non so come modificare da Latex (cioè senza rifare il disegno ed esportare) la dimensione dell’immagine.
Lo so non ho letto la guida di tikz…
metto il codice che Dia esporta:
