hole instability

Hi,

I have a PCB with board outline file that I am attempting to add mounting holes to. I have applied NPTH holes in the 2D PCB view which when pushing to 3d version display correctly the first time. However, if I return to the 2Dview, modify a component position and push back to the 3d view multiply hole errors are listed and all is shown is a brown board outline with no components pads etc. When the holes are deleted and 3d view activated the PCB returns.

I have attempted to then successfully position the holes in the 3d view. If I then push this back to the 2d, all is good but when returning to the 3d an error again occurs reducing the board to its barren brown state, except I can't then remove the holes due to being placed within the now non functioning 3d view.

Is this normal?? What am I or the program doing wrong.

Alternative question, what is the most stable process for adding mounting holes to the PCB?

Hello @graemejthomson,

I hope you're doing well. I'm going to pass this along to our developers for review. In any case, what types of holes are you trying to add?

Holes related to components should be added in the library with the component itself. For mounting holes on the PCB itself, the recommendation is to use the hole command in the 2D PCB editor. If this is what you are doing, then you are doing things correctly.

Let me know if you continue to run into issues.

Best Regards,

Jorge, thanks for the reply.

Yes, 3.4mm NPTH hole added in the 2D PCB editor. No issue adding or first render. Only collected errors second time through. No modification made to holes.

Hole then replaced with no issues. Could the layer selected when adding cause issues? This is one of two boards stacked on each other that uses the same original PCB outline. Could that cause the issue?

I have made mounting hole components with the correct NPTH hole and used these with no issues. This has added benefits of including the required tool clearances for checking 3d spatial clashes in the 3D view. This solves the issue for now. I'll try and come back to it later with the latest feb 24 release and provide an example if still an issue.

Regards.

Hi @graemejthomson,

I spoke to the developers and they let me know that they have corrected this for the next Major release. For now use your workaround.

Let me know if you continue to run into problems.

Best Regards,

I run into this problem all the time too. I've had to delete the holes once before, but most of the time I can just restart the application and it comes good next time I push from 2D to 3D.
