Join George Maestri for an in-depth discussion in this video Working with Trim and Split, part of SketchUp Pro: Tools and Techniques.
Let's take a look at two more solid modeling tools in Sketcher PRO. And these are Trim and Split. Now these essentially work like booleans. They work like subtract and intersect, but what they do is they leave the original pieces behind. So let's take a look at Trim first. I'm going to go ahead and zoom in here a little bit. And let's take a look at this first block and cylinder. So I'm going to go ahead and select the cylinder, use the Move tool to move it down along the blue axis so that it intersects with the block beneath.
Now I don't want that to go all the way through, I just want it to kind of intersect a little bit. Now typically, if we were to do a subtract, I would select the Cutting tool first, the cylinder, and select the block second. And then we can do Tools> Solid Tools >Subtract. And we've done this before. And this basically subtracts the cylinder out of the block. But that's not what we want. I'm going to go ahead and undo that operation, and I'm going to do this one more time.
Instead I'm going to use Trim. So, I'm going to select the cylinder. Shift select the block. Go Tools, and this time, I'm going to select Trim. Now watch what happens. You see this dark line comes up here, and if we move the cylinder out of the way, you'll see that I get the exact same thing that happened with the subtract, except I didn't delete the cylinder. So you kind of maintain the integrity of your Cutting tool. So as you can see, now I have almost the same situation we had before, where I have kind of this socket here for this kind of dowel to go into and I didn't need to do it in so many steps as I did before.
Now let's go ahead and take a look at the second one. And this is Split. Now Split is the same as the Intersect tool. In other words it creates a surface that overlaps two other surfaces. So again I'm going to take this cylinder, and just drop it down over the block. And select the block. So I'm going to go ahead and shift select the block. Now, typically if we were to do an Intersect, it would only keep that part of the surfaces that were overlapping, but if I undo this and select these two again, again I'm shift selecting them.
And do a split, it keeps everything intact, but it also does the intersect. So if I move this up, select the block and move that, you'll see that I have the intersect. I also have a hole for that intersect in the block, and I have my original Cutting tool intact. Now the one thing about this is that this actually is shorter, so what it does is it as it intersects, it cuts a little bit off the cylinder, and then it also cuts a hole into the block.
So basically now we have three pieces that can fit together to create the original structure, so that's a little bit different than the trim. So, hopefully, you'll find these tools fairly useful in your SketchUp endeavors.
