I have made a art document with several layers on a Macbook with High Sierra 10.13.4 version. Now in the outline version, I can see all layers, but in the retina pixel or pixel versions, I can see only half of the layers. When I save the art document, it does the retina or pixel version but not the outline view. Is there a way how to save the document like we see it on the outline view? Or do I make something wrong when I draw that makes me disappear some layers ? thanks Tabernacle.afdesign
