hi,

I am using Allegro 15.7. I have generated NC drill /Route and artwork .
but the problem is when i view them in CAM tool there scaling is not right all layers except NC drill/rout are of same scale.when i generate them in different units i.e. art wok in mm/mils and NC Drill/route in mils/mm than they match.

kindly help

Thanks & Regards,

Hi
Make sure in your NC_Param.txt and art_param.txt that the Format's match.
If your Artwork paramters are at 3 integers 5 decimals. Make sure your NC Drill
paramters match.
Also make sure you have enough decimal places of accuracy for your artworks.
You do not want a round off causing problems switching from mms to mils.

Cadence recommends designing data at or below the accuracy level the fabrication vendor supports:
Design
Units Integer Places Decimal Places
MILS 0 2 .3
MILS 1 2 .4
MILS 2 2 .4
MILS 3 2 .6 not available
MILS 4 2 .7 not available
INCH 2 2 .2
INCH 3 2 .2
