Frequent tipster Leonid Nemirovsky shares a tip about using grips in AutoCAD.
"Highlight an object to activate the grips, make one of the grips 'hot' by clicking it, press Enter, and move your mouse. That will start moving the object. While moving the mouse, press Enter again; the selected object will rotate, using the hot grip as the center of rotation. If you press Enter again, you will be able to scale the object again using the hot grip as a base."
Notes from Cadalyst Tip Patrol: This procedure is called grip mode. Grip editing objects can save a lot of time and effort; objects can be manipulated quickly without having to stop to activate commands.
Select an object or objects (without starting a command) to activate grip mode. Pick a grip to make it "hot." You can select more than one hot grip by holding down the Shift key while picking different grips' boxes. Once a hot grip has been activated, press the Enter key to change grip modes. Otherwise you are defaulted to stretching the selected grips, or hot grips.
