I see, you have to make the shape to be able to query its Area.   here's a script that adds the offset path, you can delete it after getting the area if you don't need it. Select ONE shape before running   // apply offset path to selected pathItem //https://community.adobe.com/t5/illustrator/illustrator-javascript-count-area-with-offset/td-p/11564739?page=1 function main () { var idoc = app.activeDocument; var sel = idoc.selection[0]; app.userInteractionLevel = UserInteractionLevel.DONTDISPLAYALERTS; var mm = 72/25.4; var offset = 5*mm; // offset path Effect with Round Joins var xmlstringOffsetPath = '<LiveEffect name="Adobe Offset Path"><Dict data="R mlim 4 R ofst value I jntp 2 "/></LiveEffect>'; // 0 = round, 1=bevel, 2=miter xmlstringOffsetPath = xmlstringOffsetPath.replace("value", offset); idoc.selection = null; var dup = sel.duplicate(sel, ElementPlacement.PLACEAFTER); try { dup.filled = false; } catch(e) {} dup.selected = true; // select it before applying effects // apply offset path Effect dup.applyEffect(xmlstringOffsetPath); app.redraw(); // expand appearance app.executeMenuCommand ('expandStyle'); app.userInteractionLevel = UserInteractionLevel.DISPLAYALERTS; } main();      Carlos ...

So here is what I ended up with.  You must click on the first document tab to begin. This code centers the artboard, embeds any linked/placed objects, prints, saves and closes each document from left to right (with respect to document tabs) until complete.   Thanks for everyone's help!   app.userInteractionLevel = UserInteractionLevel.DONTDISPLAYALERTS; while (documents.length > 0) { executeMenuCommand("fitin"); app.activeDocument.print() for (var i = 0; i < app.activeDocument.placedItems.length; i ++) { app.activeDocument.placedItems[i].embed(); } app.activeDocument.save() app.activeDocument.close() if (app.documents.length > 0){ app.documents[app.documents.length-1].activate();} } ...

This is a basic idea: var groups = app.activeDocument.groupItems; var d = app.activeDocument.artboards[0].artboardRect; rect1 = app.activeDocument.pathItems.rectangle(d[1], d[0], d[2], -d[3]); app.executeMenuCommand( "selectall" ); app.executeMenuCommand( "group" ); groups[0].rotate(-90); app.executeMenuCommand( "deselectall" ); rect1.selected = true; app.executeMenuCommand( "setCropMarks" ); app.activeDocument.artboards[0].remove(); app.executeMenuCommand( "selectall" ); app.executeMenuCommand( "ungroup" ); app.executeMenuCommand( "deselectall" );   ...
