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.</P> Wed, 17 Sep 2025 23:15:03 GMT https://forums.autodesk.com/t5/fusion-electronics-forum/adding-via-in-polygon-causes-airwire-errors/m-p/13815269#M20607 erussellK6Q8Z 2025-09-17T23:15:03Z https://forums.autodesk.com/t5/fusion-electronics-forum/adding-via-in-polygon-causes-airwire-errors/m-p/13816699#M20618 <P>Hello&nbsp;<a href="https://forums.autodesk.com/t5/user/viewprofilepage/user-id/10130967">@erussellK6Q8Z</a>&nbsp;,</P> <P>&nbsp;</P> <P>I hope you're doing well.
