This is the second time this has happened to me just since Autodesk took over Artcam.ĪrtCAM Layout files (*.alo) have never been compatible between different ArtCAM product ranges, so this subject has nothing to do with the transition from Delcam to wrote: Now I will have to spend the hour or two get my own layout back. I just saved the layout minutes before installing the new program. My custom layout would not load as it gave me the message that the file was INCOMPATIBLE!!?
