In this course, author George Maestri explains how to model and render 3D objects and scenes using Google SketchUp 8. The course covers the fundamentals of the application, from navigating the user interface, manipulating objects, and building basic shapes to importing objects from Google Earth, animating a scene, and modeling organic terrain using the Sandbox tools. The course also explores SketchUp Pro features, which are available as an upgrade. These include tools for creating dynamic components and adding interactivity, as well as sophisticated importing and exporting options for working with outside applications.
In addition to the standard Boolean tools, SketchUp also has a Trim and a Split tool, and these work a little bit differently than Booleans and they can also have their own advantages. So let's go ahead and create some solid objects, let's get some practice doing that. I'm going to clear out my scene and again, let's just create a box and a cylinder. So I'm going to create a rectangle and then hit P pull it out into a box, create a circle, and Again, hit P and pull it out into a cylinder.
So now I'm going to go ahead and select the box, right-click, Group, same for the cylinder. And now I'm going to go ahead and move that cylinder over the box, just like we had before, there we go. So once we have this in place let's take a look at these additional tools. Now these tools are called Trim and Split, they work very similar to Intersect, Union and Subtract. So again, I'm going to go ahead and select my cylinder and in this case I'm going to do Trim and then select my box.
Now when I do that what happens is, oh, what did happened, well if you notice here it created an edge, okay, but it left both objects intact. So in Intersect, Union, and Subtract it actually takes both objects and combines them. With Trim it actually leaves the object separately. So if I were to take this cylinder and move it off notice how what it did was it did a subtract, but it left the cylinder intact, so this can be actually be very handy if you want to use one object and keep it.
If you want to cut a hole for that object to go into, for example, you can do this much more easily than using a Subtract and duplicating objects or whatever you would have to do. So Trim is kind of similar in the way that it works, I'm going to go ahead and undo this, so let's go ahead and just get this back to where we had it. So again, I'm going to select my cylinder and this time we're going to do Split. So I'm going to select this object and hit Split, and Again, it leaves these objects intact, so let's go ahead and move them apart to see what happened.
Well what Split does is it creates an outline here for these overlap, plus it created a hole here. So what it's done is it's actually kind of created an intersection here, in fact, this created three objects. So what it's done is it's kind of made three different pieces that all fit together. So as you can see these are great for creating assemblies and other sorts of things where things have to have kind of fit together.
So let me show you real quick example of how to use these in real-life. We're going to open a file called Solids_02, and this is just basically that standard children's game where you have square pegs and round holes and that sort of thing. So I've got a couple of pegs here and I've got this board and I want to make sure I create holes for these pegs to go into the board. So all I have to do is select one of these pegs and make sure that it's completely over the board, now all of these have already been turned into solid objects by grouping them.
So if I go into Entity Info you'll see they are all solid. So I'm going to go ahead and select my triangular block here, and let's just do Trim. So I select Trim, select my Solid Group, boom, and so what I've done here is I've created a hole for this to go into, very similar to this -- that standard children's toy here. So let's go ahead and use our hexagonal peg here, and Again, we can do the same thing.
I can trim this group here and Again, just move that and now I've got another hole here, and let's just do one more for the round hole. I don't have any square pegs but you get the idea. And again, select this Trim, select my table and Again, I've got some hole that that exactly fits in.
So I hope this gives you some ideas as to how to use this tool creatively and it really is a very simple tool to use, all you have to do is make sure that all of your objects are solid groups and it should just go with no problem.
