I can give you a round-about way, if you don't like to re-specify the database to get the MM pick-n-place.Originally posted in cdnusers.org by cadpro2k
Out put the X-Y file to excel
Create a formula to make the conversion in excel
Output the file in .txt format
You can then cludge it back into a placement.txt file and import that to a MM database.
If I REALLY felt I needed to do that I would. I would prefer to change the database (setting MM decimals to 2 places) and export from Allegro. I don't see rounding as a real issue now-a-daz. Fab vendors couldn't really care about your accuracy. They care LOTS MORE about fabrication issues (line widths, spacings, impedance, etc.) They can pretty much drill anywhere; they worry about their own fabrication accuracies; and being manufacturable.
Just being me. :)
