OK, so what we're going to do now is convert our Boundaries, which are Polylines, into Regions. So we need to create Regions from these Polylines here. So we've got a Polyline there, there's also a Polyline there, there's also a Polyline there. What I've done is I've actually frozen the Layers. As you can see the landscaping's frozen, the Pond Layer is frozen, and so on. Just for clarity, and what I've done, I've put the Boundaries that we created on the Area Boundaries Layer, so there's only one Layer. Now, before we start creating Regions, what we need to do here is we need to make sure that any objects that we used to create those Regions are retained. So, what we do is we use the Delete Objects Variable: DELOBJ. So, if you type delobj like so and press Enter, you'll find that the value for DELOBJ, or Delobj as it's called, is 1. We're going to set that to zero. Now the reason we're setting that to zero is it means that it retains all of the objects that we used to create the Regions in the first instance. So now when we go to the Region Command what we can do is retain the original lines that were there. Now, do you want to do that we ask ourselves? In this case maybe not, the reason being we've already got existing Layers there, haven't we? So, that DELOBJ could still stay at 1, so you now know it exists so what we're going to do, we're going to set it back to 1 the default value. In this particular case we don't need to retain them. Think about it. We've already got existing Layers, why add more Layers to the drawing and make the drawing file size larger? So, we now go to the Draw Panel, click on the Fly-out here and pin it open, and once it's pinned open you can see that there is a Region Command here on the Fly-out Panel. So, we're going to convert the objects that enclose an area into a Region Object. So, we click on Region, select the Object, so I'm going to hover just on the edge here. There's one Polyline to create a Region from, so I click there. I want this Polyline here, I click there, I want this Polyline here, I click there. Three Regions. So you'll see there, three in total on the Command Line. I press Enter now and you'll see that on the Command Line, three loops extracted, the Polylines; three regions created. So, one, two, three Regions. What I need to do now is I'm just going to unpin my Draw Panel, I'm going to go down to the bottom of the screen and on my Workspace Switching I'm going to click on 2D Drafting and Annotation and I'm going to select 3D Modeling. You're thinking to yourself, this is a 2D drawing. Now the reason I'm selecting 3D Modeling in this case is because on the Home tab up here on the 3D Modeling, can you see we've got Solid Editing there? And we have here Union, Subtract, and also Intersect. We want to subtract. I want to subtract the pond and the hardstanding so that all I've got is a Region, like that, OK, that gives me the turf or the sod, in U.S. terms, so that I can calculate that area. So I go to Subtract here, come into the Drawing Area now and it says: Select objects. So what I'm going to do here is select the Objects that I need to Subtract from. Read your Command Line down here, look Ð Regions to Subtract from. So I click on the outer one here. I want to subtract from this, so I select the Objects; I then enter to confirm. Now select the solid surfaces and Regions to subtract. I select that one there and that one there. I then press Enter to confirm that and what it's done now is it's created just the one Region. Look. So, I've got the one Region now that gives me basically the turf or the sod that I require. So if I now just select that and I right-click and I go to Properties now, there's the area in square millimeters of the turf or sod that I need. I can easily take the decimal place back there by six places and what it tells me is that I need that amount of turf or sod to basically set up that landscaping for that building. So what I can do now is I can close the Properties Panel, hit Escape to deselect, and I now have a Region on a Layer so I can calculate that.
