EATURES :-

- Drawing History
Using the drawing revision calendar, you can compare previous versions right in the context of the current drawing.

- Compare Xref
You can now compare versions of an external reference file (Xref) and make changes without leaving the current drawing.

- Improvement of the block palette
Now the block library is available to you anytime, anywhere. Linking to content is possible from the web and mobile version of AutoCAD.

- Improved graphics performance
Now when panning and zooming in 2D, AutoCAD will automatically regenerate the drawing for faster and smoother performance. And with support for multi-core processors, 3D models will feel more responsive to orbit, pan, and zoom operations
