Hello All! I'm new to pcb design and want to confirm the correct way to limit copper area/fill. I have a simple pcb with 2 nets/no components as per attached image. The inner circle/track with 18 pads is 1 net and rest of the board is the other. Pads are plated through so bottom layer is the same. The only way I found to keep the clearance between the nets while at the same time maximizing copper between the 18 holes on the outer net was by adding a thin circle with 3. net attribute and sizing/hiding it under the track that has the outer 18 pads. Is this going to make trouble/confusion fabrication? Is there a better way to achieve this? Thank you in advance, Koep
