Hello @TS02225217 ,

you can change the diameter in the DRC-Dialog:

These settings are for all vias (pads or micro-vias) that have "auto" in their properties for "diameter".

Hello @vitalmobil ,

The annular ring settings will win over anything you set manually. So it's important to adjust the annular ring settings to whatever your board house can actually do. Remember that the drill value will always stay to whatever you set it but the diameter value is always subject to the annular ring settings.

See this article for a full explanation of the annular ring settings.

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