I exported a map from ArcGIS 10.5 as an Adobe Illustrator (AI) file (.ai). When I open the .ai file (I'm using AI CC 2019 23.0.1 on a separate Mac), my ArcGIS polygons (Fig. 1) are 'messed-up'. Specifically, polygons that originally contained cut-outs (i.e. 'holes') are now 'filled' (Fig. 2). Moreover, AI has created unneeded polygons for the cut-outs (Fig. 3), but these don't necessarily match the original cut-outs - sometimes one original cut-out is filled by a mosaic of AI polygons.
How can I export the map/polygons correctly (I DO NOT want to post-process the polygons in AI)!?
