/* This example creates and saves a blank part, then makes some
modifications. After the modifications, it reopens the part. The result
should be an open, blank part.

    1. Create a new part called a_blank_part.prt
    2. Save the part with no geometry.
    3. Create some geometry.
    4. Reopen the part.
