We're now going to look at deleting and clipping viewports in an AutoCAD drawing. Now, we're back to the three viewports that we had on one of the previous exercises. Now, what I want to do here is I want to delete two viewports and then I want to clip an existing viewport to a specific shape. So what I'm going to do here is I'm going to delete two of the viewports that I don't need, move the viewport to a new position. Then I'm going to clip that viewport to a polyline that I'm going to place on the drawing. So let's have a look at doing that. What we're going to do first of all, I'm going to delete the top viewport here. Now, before we delete the top viewport, that top left corner of that viewport could be useful. A little trick here; if you delete something but want to remember where it was, use the Circle Command, Center Radius. Pick a point on the corner there, just place a small circle. It doesn't matter how big it is because you're going to delete it shortly anyway. But if I delete that first like so, the center of the circle is now the object snap I can use that remembers the corner of where that viewport was. I'm going to delete the bottom viewport here as well. So I can either click on it and hit the Delete Key on the keyboard or Erase here on the Modify Panel or I can right click and do Erase. Notice none of the objects have disappeared in the model space. It's purely the viewports displaying them in the layout space that's being deleted. So I click now on this viewport. I right click and go to Move. I click on this corner here, move up to the center snap, left click and that viewport is now where I want it to be. So I now click on the circle, delete it and what I'm going to do, without my viewport being active, I'm going to zoom in a bit. Make sure you can always see the edges of your drawing sheet when you do that. Otherwise you might be in a an active view port and zooming and panning and you might be affecting the viewport scale. We're going to make sure that we're on our viewport layer like so and what I'm going to do now, I'm going to place a polyline around the bottom part of this view here. So it's literally polyline like so on the Draw Tab. I'm going to start about here. I'm not going to snap though. OK? So you might need to zoom in a bit more like so. Just make sure you can see one edge of your sheet of paper like this. Make sure that you don't snap to anything and it's a left click, a drag and what I'm doing here, I'm drawing my polyline around like so. It doesn't matter whether it goes outside the existing viewport or not. OK? So I'm just going to hover over that and do Object Snap Tracking, come down here, there's my intersection and then it's just a case of Down Arrow and Close for the polyline. There's the polyline just there. So now, if I go to my View Tab here, I've now got various options on my Viewports Panel. I've got Polygonal Viewport, Object converts an object to a hyper-space viewport, Viewport Clip and Join Viewports. I'm going to go for Viewport Clip. Select Viewport to Clip. So there's my existing viewport there. I left click on it. Select the clipping object. Here's the polyline here. I left click on there. Notice it clips the viewport to the polyline. If I now double click inside this, look. It's a view port and I can pan just slightly to get that view a little bit bigger in the viewport like so. Double click outside the viewport. If I select the view port, it has even remembered the viewport scale for me. So it's taken that view port scale from the old viewport and put it onto the new clipped viewport like so. So that's how you delete and clip viewports. Another little trick, while I'm here, if I just zoom out slightly, I'm just going to move this viewport up a bit. So I'm going to right click and I'm going to move, use that corner there and just drop it up there. Let's draw a circle. Let's go to the Home Tab and we'll go to Circle, Center Radius like so and I'm just going to pop a circle there. It's on the viewports layer. If I now go to my View Tab and use this one here, Convert Object to Viewports, that is now a viewport. So what I can do now, double click in here, pan. I want to zoom in on that view there. I now have an exact circular viewport to suit that view. So I can tweak that accordingly. Let's make it two to one and it fits beautifully. Double click outside the view port to deactivate it. So there are ideal ways and means of creating irregular-shape viewports, as well as deleting them when you don't need them.
