SOLVED Change outside pcb dims from Gerber file ? .BRD need help

[Overspeed]

Hello

I have a set of gerber files for single and twin AD8221 amplifier , but the original outside PCB shape is really small / narrow .

Does it is possible to increase the outside dims from a gerber file ( to 50x50mm) ? I have tried with Dimtrace but that generate an mystery offset between the new outside shape and the oldest one?

I have also the .brd file but I have not EAGLE , I link the .brd I have

I don't understand the problem.  Can you try explain better, or show us a picture?

Attached is what I see when opened in Eagle.

Ah, maybe this is what you want... I changed the dimensions to a 30mm square.  50mm is possible, but a lot of empty space.

Just for reference if anyone else is interested, this is the design

It looks like a complete eagle project, with both a schematic and a PCB file.
If you don't have eagle anymore, the eagle importer for KiCad works quite good.

Yes, the Eagle schematic and board files are available on the github repo.
But they are not consistent.  The capacitor values are different between schematic and PCB.  Something to watch out for.

Hello

First great thanks for your answers

Yes that the thing I want , I need 50mm x 50 mm for a mechanical problem as my enclosure / screw system need 50x50 , I plan to launch some in fabrication by using PCBWAY so as far that under 99x99 mm price is the same

Yes that a old Github , I agree for the cap value but capacitor value are not really important as I need a demo / eval board to compare some AD82XX between them

I usually design my PCB by using Autocad and convert in Gerber I am far to be an expert in CAD PCB , but I will learn Kicad which a good solution.
