Hi,

I have a question regarding to vias and pads in 4 layers board,
I'm using Altium 20 and generate 4 layers stackup by stackup manager and its presets feature (Tools->Presets->4 Layers).
When I place a via or pad in the board, there is a green ring around it which also dosen't resize when I resize the via or pad.
What is this ring and how can I remove it?

Regards.

Those rings are your plane clearance, you have 2 internal planes and must be a minimum clearance between the plated hole and the copper in the plane (yes, the size of the ring depends on the hole size, not the via or pad diameter), modifying the size of those rings is through your Plane Clearance rule.
