Export to CGM profile S1000D2.3 (binary) function: We manage hotspots for IPC illustrations items (e.g. BegAPS "ITEM_44133" "grobject" StList;) IsoDraw generates grobject for each layout (e.g. BegAPS "IsoG1" "grobject" StList) and for each group (e.g. BegAPS "IsoG2" "grobject" StList;). Next we use the illustrations using Isoview or any CGM viewer. When we highlight the hostpots, all the drawing is highlighted (items + groups + all the drawing as the drawing is on a layout). When we remove (manually in clear text mode) grobjects on layouts and on groups, we reach our expectations (only the items are subject of hotpots). I unsuccessfully look into your help manuals to find how to eliminate automatically the layouts and groups grobjects. Can anyone explain me how I can set IsoDraw to perform this action automatically. Thanks in advance.
