The Wipeout Command in AutoCAD is very useful for blocking out parts of a drawing that you might want to Mask, that you don't want to see in a particular drawing. So in this particular example I've placed four points there, you can see, in a rectangular pattern around the pond, and what we're going to do, we're going to Mask the pond using the Wipeout Command and then what we could perhaps do is put a Revision on the drawing saying the pond is not required at this particular point in construction of this building and the landscaping and so on. Now, the Wipeout Command itself is on the Draw Panel here, so I click on the fly-outs and I pin open the fly-out part of the Draw Panel there and Wipeout is there. Notice I'm also on my Wipeouts Layer. Always put Wipeouts on a separate Layer. So I go to Wipeout now here, and going from point to point using my Node Snap, there's my Node Snap there, left-click, left-click, and I'm just clicking on each Node as it appears and then doing. to. up to the top there. When I press Enter, there's my Wipeout. So what it does is it masks the objects and brings in the background color, which in this case is the white, and what I could do there is I could put some text in this area, and notice I can still highlight the objects. Can you see that behind the Wipeout? They're still there, they're just masked at the moment. Now, what I can do as well, which is very useful, is if I've already got an existing Polyline that perhaps forms a boundary for a Wipeout I could utilize that instead of drawing dot to. with the Wipeout Command. So I'm going to undo that Wipeout and what I'm going to do is place a rectangle using this Node Snap here to this Node Snap here using the opposing diagonals here, and I've now got a rectangle there, you can see it there. If I now go to Wipeout, come into the drawing area and instead of Specify first point, I right-click and select Polyline, what it allows me to do is select a closed Polyline there, so I click on it. Do I want to erase the Polyline? Well, if I say no, I'll end up with two Polylines Ð my rectangle and the polyline that's created when I place the Wipeout on the drawing. So, in this particular cases really I should say Yes. So, there's my Wipeout and there, look, there's a Polyline there. Can you see that on the edge of the Wipeout there? And if I hover over it you can see it says it's a Wipeout, but it is actually a Polyline with the background masking coming through. So what I could do there now is just click on that Wipeout and it will delete it like so when I hit the Delete key. So the Wipeout is made up of a Polyline and background masking. Now let's repeat that but this time we'll leave the rectangular Polyline in place. So, we draw the rectangle, we go from Node to Node there, we then go to Wipeout, and right-click and Polyline. We then select the closed Polyline and this time I'm going to say No to erasing the Polyline. So this time if I click on the Wipeout, hit Delete, the rectangle is still there. So, let's wipe that out now and put a Revision Symbol on the top. So it's Wipeout, right-click, Polyline, select the rectangle, Erase Polyline, Yes in this case. I'm now going to insert a Block and I'm going to use my REV SYMBOL again here, Specify On-screen, I OK it, there's my REV SYMBOL there, and the revision might be let's say, 2. So, there's my Revision Symbol on top of the Wipeout there, and as you can see, the Wipeout is masking the pond right now. I could put some text in there if I wanted to underneath that revision saying: Pond not required at this construction point, but as you can see Wipeouts are extremely useful for masking parts of the drawing that you don't want to use at a given time.
