Editing Paths: Knife & Scissor Tool in Adobe® Illustrator®
We're gonna go through and talk just a little bit about working with some of the other options here. We're gonna talk about the knife tool and the scissors tool real quick. These are very useful for editing paths. What I'd like you to do is I want to go down, I'm using my hand tool here holding the space bar or going to the hand tool. Come down to the bird down here. This wacky little bird thing, and what I'd like you to do is I'd like you to zoom in a bit on the bird beak, so on the beak out there. I'm using a shortcut to get to the zoom tool. It's command spacebar or control spacebar if you hold them down you get the zoom tool and then can zoom in. Try not to throw too many key commands out there just because they get overwhelming but there are a lot. All right what I want to do now is I want to take this bird beak and go ahead and click on it with the selection tool. Make sure you have the selection tool selected and you're gonna see that it's basically just a couple paths, a couple...
shapes rather and they are grouped together, you can see group up here. What I'd like to do is I want to take the beak and I want to color it. I want to have different colors as segments kind of like a toucan or something like that, right, just on the beak. Now to do that we probably have to take this orangeish shape and cut it up or do something to it. What we can do is we can actually use something like the knife tool or the scissors tool to do this. Come over here to the left and you're gonna see that we have the eraser tool. The eraser tool, by the way, Is probably my favorite tool ever. We're gonna use it a little bit maybe, we'll see. Go ahead and hold down on the eraser tool over here in the tools panel and you're gonna see we have the scissors and the knife. Now I confused these for a long time. I didn't quite understand what these were meant to do. This scissors tool is meant for you to go to a point on a path, like an anchor point, click on it and what it's gonna do is it's gonna, like with scissors, it's gonna cut the path there. You can then basically take this path and do something like this, open it up. There's gonna be two endpoints now on the path. Now why don't you come to the knife tool here. We're gonna use the knife tool instead so click on the knife tool and what I want to do is I want to come out here and we're just gonna draw across the beak here. Now what the knife tool does that's different is as you drag across the shape it's actually gonna close that shape. So it's gonna basically connect the ends of the paths. So this is a good thing. So come up here somewhere, click and drag across the beak, just all the way across to pretend you're cutting right through it, knife through butter kind of thing, drag all the way across, let go, and you've just cut it into pieces, which is kind of neat. Now did you notice that it was not even close to a straight line? Now in order to make a straight line we actually have to use the option and the shift keys or just the option key you guys. The option key held down will let you draw a straight line across. The option shift will make it perfectly horizontal or vertical, so it'll constrain it. Let's just say that. So you can do that pretty easily.
