I tried exporting a batch of drawing files into DWG using Task Scheduler. I wanted the DWG to contain all the sheets of a drawing. Some have 3 or 4 sheets. I set it to "Export all sheets to one file" and "Export all drawing sheets to paper space". However, when I open the resulting DWG file in AutoCAD, it shows an empty model tab (expected), and then only shows the first two sheets of the drawing with the tabs labeled "Layout 1" and "Layout 2". When I do "Save As" DWG, the empty model tab is there, all the sheets show up and the tabs are labeled their sheet name (Eg. "Sheet1" "Sheet2").

Is there a way to fix this so I don't have to manually open each drawing file and Save As DWG?
