Adding Via in Polygon causes airwire errors

[erussellK6Q8Z]

I have added a polygon to my routed board which had no airwire errors. Adding a thermal via to the polygon instantly caused 100+ airwire errors to appear. Any idea why this might have happened? Deleting the via removed the airwire errors.

Hello @erussellK6Q8Z ,

I hope you're doing well. When that happens just refresh the polygon, this is a known behavior. Whenever a new object is associated with a polygon its airwires reset. Refilling the polygon will make those airwire errors go away.

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

Best Regards,
