Post subject:  Gerber & NC export format

Hi everybody,
Can you please be so kind to specify what format DipTrace uses for GBR and NC export (i need both imperial & metric systems)? Can you include this info in help files and tutorial files?
This info is really critical when dealing with PCB production houses.

Thanks in advance,

When one chooses "File>Export>Gerber" the title of the new window says "Gerber RS-274X". You can then select just about all permutations of 274X for that window. In fact, you can also set aperture information which is really more for RS-274D (274X contains the aperture file; 274D requires a separate aperture file. Most people and board houses use and prefer 274X).

The NC drill is a bit more obtuse; usually one can specify one form or another of Excellon with options; unclear what this NC is creating.

This answer is not exactly what i meant: what i need is knowledge of EXACT parameters Diptrace generates its nc and gbr files. Something like:

metric 5:3 leading absolute
inch 2:4 leading absolute

I need date like this.

Inspecting a generated gerber file in Notepad (the gerber is an ASCII file) gives the following information:

Inch mode
i.e. Leading, Absolute, 4:4
i.e. resolution is 1/10 of a mil (0.00254mm)

Millimeter mode
i.e. Leading, Absolute, 5:3
i.e. resolution is 1/1000 of a millimeter (slightly better than in 'inch' mode)

I found no place to change this in DipTrace, but board houses should be fine with both settings as is.

Sorry no info on NC drill.

Regards Syl

Different CADs export Gerber files with different extensions. By default, DipTrace exports files in the way <Layer name>.gbr, but you can rename files as you want.

Follow the below steps, that may help.

Choose ‘File > Export > N/C Drill’ from the main menu.The ‘Export N/C Drill’ window will open and then Press the “Auto” button to define the tools and then click “Export.”
