Express Tools
The Express Tools are a set of officially unsupported but nevertheless pretty reliable “bonus” commands. The Express Tools are an optional item when you install AutoCAD, and I highly recommend you choose to include them. There are additional drawing and editing commands, a far more elaborate hatch routine than the regular HATCH command, and commands for working with blocks and xrefs, text, dimensions, and layouts.
Because most of the Express Tools are written using the APIs mentioned in the earlier “Customization Options” section, they won't work in AutoCAD LT. On the positive side, sometimes a few of the Express Tools are moved into the core of the AutoCAD executable; because they're not using one of those APIs I mention earlier, they can be made available to AutoCAD LT. For example, AutoCAD LT 2012 now includes the OVERKILL command for weeding out duplicate objects that had previously been an Express Tool.
