Is there a way to view a preview of the drawing when opening or searching in finder, like AutoCAD for windows? The Thumbnail I get is just a large DS logo for .dwg files. I am using DS for Mac. The program is a great Autocad sub for 2D use in a mac, but the preview is really missed, especially since the open dialog isnt limited to just .dwg files, but has .bak, and any other filetypes available in the folder shown. I know there are third party apps for viewing acad previews, but I would rather see it in the DS program. Is there a "save preview" or "set initial preview" that needs to be clicked for each file when opening and closing/saving?
