Each selection method we have looked at so far has required us to actively click on an object or create a window. In this lesson, we will look at how we can select objects using a keyboard shortcut. Using these shortcuts, we can make selections without having to touch the entities. On my screen, I have an architectural example; this geometry represents a floor plan for a small hotel room. The first keyboard shortcut I would like to look at allows us to select all the geometry in the file. For instance, maybe I would like to change the orientation of this room.
To do that, I will launch the Rotate command. And at the Select objects prompt, I will type all and press Enter. And you can see that AutoCAD has selected all of the geometry in the file. I will press Enter again, now that I am finished selecting objects. For my base point, I will select the upper left corner of the bed and for my rotation angle; I will type 180 and press Enter. So all allows us to select all of the geometry in the file. Let's zoom in the bedroom area and I would like to create a lamp on the top of this nightstand on the right side.
I will use the Circle command for this and I would like to draw my circle at the center of the top of this table. So I am going to Shift+Right-Click to bring up the Objects Snap menu and I will choose Mid Between 2 Points, and I would like the center of this lamp to be at the midpoint between the upper left corner and the lower right corner of the table. I will then give my lamp a radius of 6-3/4". Remember, this is an architectural example. Next, I would like to create a copy of this lamp on the other nightstand.
I will move up and launch the Copy command and at the Select objects prompt I will type l and press Enter; l stands for last, and you can see the AutoCAD has selected the last object that I created. I will press Enter again to finish my selection, and I will pick the lamp up from the lower left corner of the nightstand on the right side and I will place it to the lower left corner of the nightstand on the left side. When I am finished, I will press Escape. Let's pan the drawing up a little bit, down at the foot of the bed I have got a small desk and a chair.
Currently the chair is facing the narrowest part of the desk. I would like to orient the chair such that it is facing this larger area. To do that, I will launch the Move command and I will create a window to select the chair geometry, I will press Enter, when I am finished. I will pick the chair up from the midpoint of the front, and I will place it to the midpoint of this edge. Next, I would like to rotate the chair. At the Select objects prompt I am going to type p and press Enter; p stands for previous, and you can see that AutoCAD has reselected my previous selection.
I will press Enter when finished. I would like to rotate the chair around the midpoint of the front and I will rotate it to the endpoint of this corner of the desk. Next, I would like to push the chair away from the desk a little bit, I will launch the Move command for that, at the Select objects prompt I will type p for previous. I will press Enter to finish this selection and I will pick the chair up from a point in space here and drag the chair away slightly and I will click when I am finished. Finally, I will double-click my mouse wheel to do a Zoom Extents, such that we can see the entire drawing.
So in the event you need to select the last object you created, or a previous selection set, or all of the objects in the drawing. I am sure you will agree that making selections using a keyboard shortcut could be one of the fastest ways to select objects.
