Drill holes from 2D PCB not going through board on 3D PCB

[Anonymous]

The holes from a drill command are not going all the way through the PCB when the 3D is viewed. Cutouts, Vias, and component holes all seem to be there, but not any drill holes. The drill punches through the silkscreen and copper layer on the PCB, but not the "board" layer. I have tried unlinking the 3D PCB and deleting it(successfuly), with no change in the holes. Any help would be appreciated.

I'm seeing the same thing but intermittently (same component/library/package drills the holes in one design but not another).  In all cases the 3D package on library.io shows the through hole when locating the 3D model on the board.

Just got prototype boards back - the Gerber files are correct and include the drill as they should regardless of whether the drill appears in the 3D model.  This appears to be a translation issue from Eagle/Fusion Electronics to the 3D representation of the board.

I am also seeing this on my design.  It seemed to start happening "all of a sudden": previously the holes were fine, now they have this issue.
The hole is just a "hole" in eagle (i.e. not plated through hole component or anything).

Hello Everyone,

I hope you're doing well. By any chance has anyone altered the thickness of the board in the DRC? @HelenChen-ElectronicsQA It's possible this has already been reported, but could you confirm?

Sometimes making the board thicker causes the cutouts to be under (or inside the board) the surface layers of the PCB.

Let me know if there's anything else I can do for you.

Best Regards,

Hi Jorge,

Thanks for your reply. I did change the stack-up of the board (and thickness) a few times, though I can't say for sure whether the problem on fusion started to happen at the same time.

Hi @jorge_garcia , @otedder ,

I tested this from EAGLE 9.6.2 to Fusion, and pure Fusion to view 3D PCB, no such issue in my test. In the past we fixed similar issue ago.

Do you mind sending your file to us to have a try?

And could you please delete the holes and recreate it again, and see whether this issue still reproducible for you?

Thank you very much.

Regards,

Helen

I am seeing the same thing, in a current design. The holes were correct the first few times I pushed the board to Fusion 360. I then changed the DRC file, which I think may have changed the board thickness (different board vender). Now only one of 4 identical holes is actually shown through the board in fusion 360. I tried deleting the holes and recreating them, but got the same result. I even tried copying the one hole that was correct and placing it at the other 3 locations. The result is still the same.

Hi @REHolt218 ,

Sorry to hear that you're having trouble.

Do you mind making a simple board file with the drill holes which have problem and attach the board file here? We could use your test file to have a double check.

Thanks a lot.

Best regards,

Helen
