Dear Everyone, I am a beginner of EDA, I just started to work on openearable ([OpenEarable v1.1 Earpiece - EasyEDA open source hardware lab (oshwlab.com)](https://oshwlab.com/openearable/openearable-v1_copy_copy)) However, I can't pass the DRC test due to the mismatch between DRC rule and the setting.  you can easily reproduce the problem by run DRC on the link I provided above. from observation, I find actually the diameter and DRC diameter are same from the perspective of mm, but with a difference from the perspective of mile. I believe it is a trivial error for beginner, I appreciate any help!
