Hi all,

The gerbers exported by Fritzing seem to use a different amount of decimals for different files.  
For example, here is a very simple copper top and associated drill file.

Copper top:

```auto
G04 This is an RS-274x file exported by *
G04 gerbv version 2.10.0-rc.1~19b8ba *
G04 More information is available about gerbv at *
G04 https://gerbv.github.io/ *
G04 --End of header info--*
%MOIN*%
%FSLAX36Y36*%
%IPPOS*%
G04 --Define apertures--*
%ADD10C,0.0748*%
%ADD11C,0.0866*%
G04 --Start main section--*
G54D10*
G01X0822000Y1822000D03*
G54D11*
G01X1022000Y1822000D03*
M02*

```

Drill:

```auto
M48
INCH,TZ
T10C0.063
%
T10
X010222Y018222
X008222Y018222
M30

```

As you can see, the coordinates in the drill file seem to have less digits.

Unfortunatly this difference is causing issues in the software I use to print the boards.  
Manually editing the drill files by adding two 00’s after each coordinate fixes the issue but is very cumbersome. I could write a script that would do it… but this is also not ideal.

If possible, I would like to configure the gerber exporter to handle this. Does anyone have any experience with this? Know where I could get started?

Regards,

Marten

Your best bet is to open an issue here:

as this very likely needs a code change. AFIIK there are no gerber output user settable parameters.

In theory (but possibly not in practice, gerber processing is complex) the fix should be fairly easy just adjust the number of emitted digits. I guess we will see if that is true or the situation is much more complex (which unfortunately is entirely possible!)
