</p><p>Questa GUI permette di ruotare la vista con maggiore precisione rispetto a quando si utilizza il mouse. La rotazione avviene intorno ad assi fissati rispetto all'utente e non agli oggetti, lo scopo è quello di ruotare gli oggetti approssimativamente attorno al loro centro invece che attorno al centro della vista.
|
|
</p><p><br />
|
|
Per impostazione predefinita, la GUI viene visualizzata in alto a destra dello schermo, si può cambiare questo comportamento modificando

alla fine della funzione 'initUI'. I primi due argomenti (right-300, 0) stabiliscono come posizione l'angolo in alto a sinistra della finestra - per esperienza questa posizione si adatta bene ad Ubuntu, ma con Vista la finestra risulta troppo in alto per cui è meglio sostituire lo 0 con un valore vicino a 30.

</p><p>I sensi di rotazione sono rappresentati da tre icone. Un file zip contenente queste icone è disponibile <a rel="nofollow" class="external text" href="http://forum.freecadweb.org/download/file.php?id=453">quí</a>, le immagini devono essere collocate nella cartella che contiene le macro.
