Autocad Tip

For the CAD Keyboarder who doesn't mind a little typing.

TSPACEINVADERS-Creates a selection set of texts with overlapping geometry.

NCOPY-This command let's you copy objects that are referenced or nested into your current drawing.
XOPEN-This command let's you open any xref in a separate window just by clicking on it. Would be nice if it would take you to that exact location you are selecting though.
XLIST-Will list object data such as Layer, Linetype, and Color of a nested xref or block.
BLOCKREPLACE-Does just what it says, replaces one block with another block.
LAP-Let's you quickly change the Bylayer Color and Linetype of an object, even if it is nested.
