We're now going to look at the Copy Selection Command, not the Copy Command on the clipboard. And we're going to use Coordinate Entry to copy objects this time. Now, I'm going to use the right-hand shortcut menu. So I'm going to click on the object itself first. I'm then going to right click with the object selected and go to Copy Selection. Do not use Copy or Copy with Base Point here. We'll look at those later. We're going to go to the Copy Selection Command here. As usual, we're prompted for a base point. My base point is going to be this end point snap here, so make sure on your O Snaps down here, when you go to Settings, that your End Point is on, like so. Make sure also that your Object Snaps are on. Now, our base point is going to be this end point snap here as stated. As I drag downwards, you'll see that it goes into Polar Tracking Mode because my Polar Tracking is switched on. That is one method of Coordin Entry. However, I can just input the coordinates that I want because as soon as I click on the base point, any subsequent coordinate is a relative coordinate, relative to that base point. So I want that table there to move downwards by 25 units. So in the Y direction, we're going to go 25 units downwards, so negative 25. It's not going to move in the X direction so the X direction is going to be zero. So I type in minus 25 like so. Now, that is not correct, is it; because that's my X Coordinate Box. So I need to make sure that I put zero in there and then comma and then I put in my minus 25 for my Y direction. Always make sure that you get your X and Y the right way round. Press Enter and that is now copied exactly 25 units below its counterpart. I press Enter now to finish the Copy Command. Now, I can check that particular distance by way of using the Distance Command. So let's use the Distance Command. There will be questions within your AutoCAD 2009 Certified Professional exam where you are asked to measure distances. So we go to the Tools Tab at the top of the screen here and there on the Inquiry Panel is our Distance Command. So let's measure our distance. So we click on Distance. I'm going to measure from here, left click, to here, left click. You'll see the distance appear because the Dynamic Input is switched on and as you can see, the distance is 25 degrees. Going downwards in the X-Y plane is 270 degrees. The angle from the X-Y plane will be zero because we're not working in 3D. Delta X you'll notice is zero because we didn't move anywhere in the X direction. Delta Y is the value that we put in; our relative coordinate: naught minus 25. Because we're working in 2d, Delta Z will remain zero. So as you can see there, we can check our distance that we copy or move in AutoCAD. It's a good habit to get into because the distance command will be required throughout your Certified Professional Exam. Let's have a look now at going in another way with, again, Coordinate Entry. Now, what you need here is the ability to think slightly laterally. Now, if we look at these two chairs here, we can see that they are next to each other and have a regular space between them. Let's use the Distance Command again. Let's click on Distance. I'm going to select the midpoint on the back of this chair here to the midpoint on the back of this chair here. And as you can see, the distance is 30. Now, that's good news. If we know that that distance is 30, if we want to copy another chair into this space here, we know that we've got to move it 30 units to the left. But we need to copy it. We want to leave these two chairs here. So what I need to do is I need to copy the middle chair but use a different base point. So I go back to my Home Tab now. I'm going to select Copy Selection on the Modify Panel and at the Select Objects Prompt I'm going to click here on this chair. I then press Enter to confirm. It now asks for a base point. Now, I know I want to move 30 units to the left. But what I could do here is I can do this in two ways. I could click on any Object Snap on the chair and just move to the left and put the coordinates in or use Direct Distance with the Polar Tracking. Let's do something slightly different. The base point is going to be here; this point here. So I left click on this midpoint snap here and what I can do now is put my coordinates in so I'm moving to the left, which means the X is going to be negative. I'm not moving upwards or downwards, so the Y will be zero. So as I move now to the left, I get prompted with my Polar Tracking. I'm going to type in minus 30 in the X direction comma zero in the Y direction and press Enter. Now, you'll notice there my chair is spaced exactly. Press Enter to finish. Because what I've done, I've copied this chair here using this point here. So as I've moved across, in essence I've moved from there to there but obviously it's offset so the chair goes there; the copy chair goes there. So as you can see, lots of ways and means of working with Coordinate Entry.
