Hi

I wonder if anyone has any insight to this.

I have vias set with a 5mil annular ring as per PCB makers minimum but the PCB maker reports them as 4.859mil and thus below the 5mil they want.

Is this an artefact of some setting (gerber file perhaps) or is it a math rounding error internally, or something else?

I’m using BZR 4296.

Thanks
