Gerber settings to extend range in under format

Micheal schenk

I am using OrCAD PCB Profession 17.4 with the latest hotfix.

I want to use the format of 3:8 under gerber settings but the software shows the limit on range from 0 to 6.

IS there a way where I can extend the range or is it fixed

.

  • It is limited by the gerber format:

    From the Ucamco Gerber File Format specification document:

    The coordinate format specifies the number of integer and decimal places in a coordinate
    number. For example, the “24” format specifies 2 integer and 4 decimal places. The number of
    decimal places must be 4, 5 or 6. The number of integer places must be not more than 6. Thus
    the longest representable coordinate number is ‘nnnnnn.nnnnnn’
