V4 - Drill size tolerance too tight for 3,5mm.
According to the delivery panel “EDA-02189-V4_pnl_gbr”, the tolerance assigned to drills of diameter 3,5 mm is ± 0,005mm. But the manufacturer wants to change this tolerance with their standard 0,05mm for production. This is in compliance with their production process.
Check if tolerance can be relaxed to 0,05mm and correct production files accordingly.

This is a design office’s error. In the file “EDA-02189-V4_mfg”, on 1st page, we specify a 3.5 hole with 0.005mm tolerances. Bad idea…. I will ask for correction in our template.
- verify if will be improved at a next version.
