Ciao !
Allora :
1) Assicurati che la property "dwg2pdf.root=" punti alla root dell'installazione di Qcad e non all'eseguibile(.exe)
2) All'interno dell'installazione Alfresco vai sulla cartella "bin" ed esegui lo script "apply_amps.bat"
3) sempre all'interno dell'installazione Alfresco vai al sulla cartella "extension" che sta su tomcat\shared\classes\alfresco\extension, crea un file dentro la cartella e chiamalo "dwg-context.xml" (assicurati che l'estensione sia .xml) e inserisci all'interno il seguente contenuto :

4) Riavvia Alfresco, e adesso da Share dovresti riuscire a visualizzare i file.
Ho eseguito esattamente questi passaggi sulla mia attuale installazione e funziona tutto correttamente.
Per qualsiasi cosa, non esitare a contattarmi,
Spero che con le seguenti istruzioni tu riesca nell'intento !
