DRILL DATA IS INCORRECT

Hi, After Generating the Gerber file, Once the file is opened, the Drill data is mismatching. The PCB file I designed is shown in below. ![image.png](//image.easyeda.com/pullimage/37yWyc6ldGmNtU1iPHFYeHM3n6rtJ2ijZz0XETbT.png) below is the generated gerber. ![image.png](//image.easyeda.com/pullimage/absgGJgMOvjq6al3T10CShJe48r3bUhBG7tfA1ui.png) I tried the previous easyeda version that I was using(easyeda-windows-ia32-6.4.25), but the issue persists. One more thing is that, the issue is for this file only. the size of this board is (26x20mm). For a bigger board, this issue is not observed.

@UserSupport, I can confirm that there is something wrong. It seems to be a problem with the PTH layer but it is not that simple. It may be a problem with gerbv but I have not tried other Gerber viewing s/w. Please see the two PCBs in this demo project: [https://oshwlab.com/andyfierman/pth-hole-problem](https://oshwlab.com/andyfierman/pth-hole-problem)

@andyfierman That is the Gerber viewer tool doesn't fit the drill size unit, you can change the Drill unit format as 3:3 or 4:2 at Gerber viewer tool

EasyEDA drill unit format is 3:3, if the PCB size is too big, the unit format will changes to 4:2 to make sure the drill hole is correct for the factory

@UserSupport, I don't think that is correct. The two PCBs in my pubic examples are the same size. Only the Footprint in them changes. One PCB gives the PTH holes in the same scale as the rest of the board online and silkscreen, the other changes the PTH holes scaling. Please check my examples at: [https://oshwlab.com/andyfierman/pth-hole-problem](https://oshwlab.com/andyfierman/pth-hole-problem) :)

**@UserSupport, ** This may be an issue with different versions of gerbv (and maybe some other viewers: I do not know what Gerber Viewer the OP was using). Yesterday I created and checked the 2 small (20mm x 20mm) PCBs in my example using gerbv V2.7.1 on Linux and saw the problem in one board and not the other. This morning I have just added two more PCBs to my example. There are now two 20mm x 20mm boards and two 100mm x 100mm boards. I then checked the Gerbers for all 4 boards using the latest compiled version of gerbv for Windows which is the gerbv-beta version (identified as V2.6.1) from here: [https://sourceforge.net/projects/gerbv/files/gerbv/gerbv-beta/](https://sourceforge.net/projects/gerbv/files/gerbv/gerbv-beta/) or: [https://sourceforge.net/projects/gerbv/files/latest/download](https://sourceforge.net/projects/gerbv/files/latest/download) All 4 boards are displayed correctly in gerbv V2.6.1 on Windows 10. **@sujinkoovery, ** What Gerber viewer are you using?

@andyfierman He seems using CAM350, CAM350 will not fit the location automatically, need to modify drill format manually
