Mike Klever shares some advanced AutoCAD grip-editing techniques.
"While experimenting with Cadalyst CAD Tip No. 3749, I found that it doesn't work in my version of AutoCAD Civil 3D 2011, but I stumbled on another use for the Ctrl key when modifying with grips. I frequently use highlighted grips to stretch, move, rotate, scale, and mirror objects, using the space bar to cycle between options. (I could also right-click and drag to copy, but I would then have to re-select the object and repeat if I wanted additional copies.)
"I have found that after selecting a grip and cycling with the space bar to move, for example, if I hold down the Ctrl key as I drag the object, it initiates a Move (multiple) command which produces results similar to the Copy command. Why not just use the Copy with Base Point command? By highlighting the object and grip, I have already defined an object and base point. It's just another way (of many) to copy an object. And, yes, it works with mtext, too."
Notes from Cadalyst Tip Patrol: Grip-editing objects in AutoCAD is a great way to do more with less. It's as simple as selecting the object(s), then selecting the grip, then manipulating said grip. But there are more grip-editing tools available to us than that. Select your object, select a grip, and press the spacebar. This will cycle you through many grip-editing options. By default, grip editing is set to a stretch manipulation. But you can cycle through the following additional commands: Move, Rotate, Scale, and Mirror. This lets you access to several commands, without starting a single one of them! Now press the Ctrl key while executing any of these commands; it will turn into a multiple of that command. Also, take a look at the AutoCAD setting GripSubObjMode; it will affect your grip selection functionality.
