Yet again it's guess which object has been erased from the drawing? In this case you'll notice the reception table has been removed from this office here and an AutoCAD point on the Points Layer has been placed there instead. This is deliberate, and what we're going to do is we're going to utilize the CIRCLE Command now to place a reception table in this office here. So, what do we do first? We always check our Layer first. So, Home tab, Layer Panel, click on the down arrow there to get the pull-down menu, and we need to be on the Furniture Layer. Our reception table is a piece of furniture so we put it on the respective Layer, the Furniture Layer. Again we'll zoom in a little bit, let's roll in on the wheel mouse a bit so we can see what we're doing, and what we're going to do now, this is going to be the center of our table there, that Point. Now, what we'll do Ð that's a sacrificial point, so we can delete that once we've placed the table because there will be a Center Snap for the table once it's placed as a Circle anyway. So, let's have a look at this now. I'm going to show you two different types of Circles; there are also many other types of Circles in AutoCAD. Before we do anything, though, we go down to OSNAP on the Status Bar, right-click, and we make sure that the Node Snap is on, because when we use our Points, remember, it's a Node Snap. So Node is on. It's got the blue square around it. So hit Escape to lose the menu. Remember not to click on Node because that will switch that Snap off. So, we now go up to the CIRCLE Command. So there's the CIRCLE Command there. The default as you can see is Center, Radius. But if I click on the down arrow here on the fly-out menu, as I said, lots of different types of Circles for different environments, different occasions. Now if I use the Center Radius option here, the default option, it prompts me to specify a Centerpoint for my Circle. Well that's easy. I hover over the point there, the Node Snap is on so it picks up the Node Snap and I left-click. As I mov the mouse out now, you'll see the Circle get bigger and smaller because I'm telling AutoCAD to make the radius bigger or smaller. But you'll also notice on the Dynamic Input now you can see that I've got a Distance Box. That Distance, at the moment, is a Radius. So if I type in 500 millimeters for my Radius and press Enter, there's my reception table. So, that's using Center Radius. Now you'll notice down there on the Command Line the words Diameter in square brackets. That means that that word Diameter is available on the Shortcut Menu. There are two ways of doing a Center Diameter Circle. Let me show you. Let's select the Circle here and using the Modify Panel we'll erase it. The quickest way is to go to the fly-out here, Center Diameter, again you're prompted for the Centerpoint, hover over the point and get the Node Snap, left-click, and now it prompts you for the Diameter, and as you move out you can see, look, the diameter now is slightly different. It looks different, yeah? So I type in a diameter of 1000, remember, because the diameter is two times the radius, press Enter, and I've got the same reception table as you can see? Let's erase it one more time. Click on the Circle, click on Erase. Make sure that you pick on the edge of the Circle. You won't be able to select it if you move inside and try and pick it. So, I'm going to go back now to here, click on the fly-out, and I'm going to go Center, Radius. Now you're thinking here, hang on a minute, he was talking about Center, Diameter Circles? I still am. Watch and learn what happens here. I still pick my Centerpoint here, so there's my Node Snap and I left-click. Now I am in Center Radius Mode, you can see that there, yeah? Now, if I right-click on the Shortcut Menu, like so, I've got the Diameter option there, or if I press Escape there a second, I'm still in Radius Mode there, if I press the down arrow on the keyboard and utilize my Dynamic Input there, it remembers the last Radius I put in; it also prompts me, if I want to put a Diameter in. So, I've got two options here, OK. Diameter or a 500 Radius. If I select Diameter there it now goes into Center Diameter Mode, prompts me for the Diameter of the Circle, which is 1000, and Enter, and there's my reception table again. Now, the other trick, of course, is if I need to draw another one of these reception tables now, and I'll just do this quickly off the cuff over here in this space here; we will delete it afterwards. If I now go back to Circle here, I'm in Center Radius Mode, yeah, click on Center Radius and come here and pick a Centerpoint, it remembers the last Radius that I put in. If I just press Enter there's my 500 Radius. So if I've got 50 or 60 reception tables to draw, I draw the first one and put the Radius, or the Diameter, that's it, and then every time I draw a Circle after that using Center Radius, or respectively, Center Diameter, it's Centerpoint and Enter, because it remembers the last input put in. Very useful if you've got lots of Circles to draw. So let's erase that, click on the Circle, click on Erase, and as you can see there the CIRCLE Command, again, versatile, quick, very easy to use.
