To activate the AutoCAD Express Tools, use the EXPRESSTOOLS command.
The library files for the AutoCAD Express Tools are not loaded at AutoCAD startup by default. This was done to reduce the time needed to load AutoCAD. The libraries load the first time that an Express Tools command is issued, creating a delay the first time you use an Express Tool in an AutoCAD session. You can use the EXPRESSTOOLS command to force the AutoCAD Express Tools libraries to be loaded at the beginning of the AutoCAD session.
If the AutoCAD Express Tool commands are available on the command line but the Express menu is not displayed, use the EXPRESSMENU command to display the menu.
