Using GRIPs To Edit Objects
AutoCAD’s GRIPs provide object-specific editing tools that assist when modifying AutoCAD objects such as the rectangle shown.
Upon selection, any AutoCAD object displays its GRIPs. Any GRIP can be selected and made in to a “hot” GRIP (again, see the rectangle shown). Either the shortcut menu or the command line shows the GRIP edit tools.
The shortcut menu tools are shown and you can press the spacebar to toggle between the GRIP edit tools if you are using the command line. Just press the spacebar to move to the next edit tool.
