Something that came up on a recent training course was the new curve editing feature that was released when the 2012 range of products came out.
This is the Create Blend Curve command (located under the Fillet and Chamfer tools) in the modify section. Useful in3d modelling to create smooth tangential curves and for road design.
Or Type in 'Blend' to access the same command. It comes with both AutoCAD full version and LT. Worth checking out whatever your drawing discipline may be!
