I'm brand new to EZCAD3. I see the file extension is .ez3. I've never used EZCAD2, but I think the file extension is ezd. I have some ezd test grid files I downloaded from JeffryJ's YouTube video (https://www.youtube.com/watch?v=gAhNCu6hHME), but I can't open them in EZCAD3. Is there a way to open these files in EZCAD3?
