Now I use Circuit Studio.
I downloaded AM571x Industrial Development Kit(IDK) Gerber Files — SPRCAG3.ZIP (8971 KB)(https://www.tij.co.jp/jp/lit/zip/sprcag3),and tried to open Gerber File(file extension:.art).https://www.tij.co.jp/jp/lit/zip/sprcag3
But I could not open it.
What I tried
(1)Right-click on the ART file → open, only show text.
(2)Create PCB document → File → Import ,the message invalid fomat appears.
Correctly I think I can see PCB pattern like a picture.
Could you tell me what to do if you know.
