We have incorporated the ATA numbering system into our drawing file structure recently.
Does anyone have any suggestions as to how we can effectively number parts, prints, and assemblies with this numbering system? Is there a standard to the industry for numbering these different drawing parts.
Any info. on this would be greatly appreciated.

Bell Helicopter uses a fairly handy numbering system that's quite easy to follow:
Model-assembly-part-revision
therefore an original structural component on a 212 could be:
212-032-165-001
They don't use the ATA100 number in the part number, or else there would be WAY too many 212-053-* parts for their preferred 12 digit system, but that doesn't have to stop you. The -030 and -032 number refers to "aluminum sheet structure" or something like that. Every time they change a particular part, the last number goes up an increment. The *-165-001 is changed with a *-165-002, -003, etc. 字串6
If you work on a job-by-job basis, you might find a simpler system more manageable. Our part numbers are identical to drawing numbers (with a dash number to match the item number on the drawing, too). Adding serial numbers to the end of these part numbers has been clumsy, though.
You should consider a "next-higher-assembly" line in your title blocks to indicate where the part goes in the seqence of drawings.
