I think that this thread has changed its real intention.
The initial question was how to produce a process flow diagram for use and submission for PPAP requirements.
General flow chart software questions are in threads such as

Typically the flow charts for
APQP/PPAP are as simple as Bill Ryan's example.
To broaden the discussion
Does any one submit more elaborate flow charts with PPAP?
Do you use the process flow diagram that you submit with PPAP or an alternative?
