Interface Overhaul for Multiple Documents Multiple documents opening feature in separate tabs of their own is new addition. The tabs can be turned on or off and an overflow button lets access to more tabs if opened. A lock sign on tab indicates read only drawing whereas asterisk implies a drawing with unsaved changes. Hovering over any tab, which is not the current tab, pops up a mini window, which features a zoomed out view of the drawing in the tab. Right click on tabs opens up options to save, close, create and other options. The AutoCAD Command Line The command line can now predict the nearest command if you misspell it in typing. Further, the command suggestion now searches for the typed string in all commands, not just commands beginning with it.
