Trim and extend portions of a sketch - SOLIDWORKS Tutorial

- [Instructor] This video's going to cover the Trim and Extend tools inside of Sketches. Now, the tools are available right up here, under the Sketch menu here and I've got the Trim Entities and directly below that is Extend. Let's start with trim. And you got to to put a bunch of different options here. I've got the Power trim, Corner trim, Trim away inside, Trim away outside, and Trim to closest. Now, these are all powerful and they're all great, but you know what? I never use anything besides my friend, the Power trim. But let me show you the other ones first. So click on Trim to closest and I just choose the line segment here and it's just going to trim that back to the closest line that it sees. Same thing over here, I can just trim it away, trim it away, trim it away. Pretty basic and straight forward. Alright. Let's go ahead and use the undo command a few times and put those lines back. Alright. And let's go ahead and do it one more time. So this time I'm going to say Trim away outside. So I'm going to go ahead and choose this one here. I'm going to choose this line and that line, okay. And then I can choose the lines themselves and notice this is going to trim everything between these two lines. So choose that one there, choose that one there, choose that one there, it's going to trim away everything on the outside of those lines. Pretty handy. Of course let's go back a couple times here, so we're back to where we were. Again, Trim away inside, same thing, you're going to choose the lines and this time it's going to trim everything between those two lines. Pretty straight forward and easy to use. And then, let's go down here to Corner trim. I'm going to choose like this line here and that line there. It's going to trim away everything that's outside of that corner. Straight forward, easy to use. Let's go head back one more time. Now, for my favorite, which is Power trim. So, Power trim allows you to draw this little line and anywhere that line goes, it will trim away that thing to the next closest thing it sees. So, notice right here on my screen, I have this little gray line, and I'm drawing a circle or a little spiral here. And wherever that little line goes, think about like a pencil, anything I go through, it'll automatically trim it away. Come over here, trim it away. Alright. Come down here, trim, trim, trim, trim, trim, trim, trim. You can trim everything away as you go through the design. Mkay. Same thing up here. Trim away, trim away, trim away. Now, you don't have to hold the whole thing down the whole time, you can click and just drag it across, but just think about you're taking a line just kind of slicing through it. And it'll easily just trim everything away to the next thing it sees. So, that's Power trim, it's really powerful. I'm going to go head and undo a few of these things too. And I do want to point out one other really cool trick, using Power trim. So, I'm in the Power trim command, and if I trim this away, notice if you go back to that little dot, that dot right there, you'll bring back your last option. So, if I trim this away, go back to the red dot, and it'll undo that last trim. So, anyways that's Power trim. I pretty much only use Power trim so, I would recommend just using Power trim. The next one I want to show you is the Extend. So, under Trim Entities, there's also the Extended Entities, or Extend Entities. And just choose a line, and it has to have something in front of it. So notice the circle's in front of this line here, click on that, and it'll just extend it over to here. This one, it'll extend it over to that one there. This one will extend up to here. This one will extend over to there. This line will extend to there. This one will go over to here. But like this line over here, it won't do anything cause there's nothing below it, right? Over here it won't work either cause it has nothing for it to hit. So it has to have something in front of it to run in to. So, that's pretty much all I have, because like, I can click on that one there, I can click on that one there. Over here, nothing. Over here, nothing. Over here, I can extend it a little further. So, anyways, keep it in mind just if you want to extend a line you can just click on it, it has to have a line in front of it to work, but again it works pretty straight forward and simple; as well as that Power trim or any of the other Trim tools that you have available to you.
