SU Fundamentals 8-1 Components

0:03 We've covered the idea of grouping, and in some ways groups and components look and behave the same.

0:12 They both act as a single object that can be moved, copied and rotated, but the big difference comes when you edit them.

0:22 Groups are unique, so any copy of a group will be a unique copy.

0:28 Components however, are instanced, so all copies will be affected when you edit any one of them.

0:36 You should always combine your geometry into either groups or components and the general rule is to make a component of anything that will be copied.

0:49 The default shortcut key for components is ‘G’, or you can create them through a right-click menu.

0:58 When you create the component, you’ll be promoted right away to name it.

1:04 This is a always a good practice to keep your models organized, and, we’ll explore some of these other settings later, let’s create this component now.

1:13 You can copy and paste a component.

1:16 You can also make copies with the move tool by moving the component and tapping the CTRL key on Windows, or the Option key on Mac.

1:27 We’ll learn more about copying with the move tool later, we just need a few copies of this pillar for now.

1:34 Let’s edit any one of these pillars.

1:37 As with groups, to edit a component, the best method is to use the select arrow, and double-click on the component, which then shows the dotted line, editing box.

1:50 Click away from the component to close it.

1:53 Double click to edit, click outside the component to close it.

1:59 In our example, these center pillars could be wider to match the connection to the arch.

2:04 If I select these 4 pillars, I can right-click on one of them and choose ‘Make unique’.

2:12 This will break the connection to the original components, which can be seen if we make a few changes.

2:20 To see this in a different view, open the Components Browser from the 'Window’ menu.

2:26 Here we can see the original pillar component and the unique copy we made.

2:32 Let’s make another one ‘unique’ to see how it will also be added to the components browser.

2:40 The components browser is an important tool in managing and finding new components.

2:47 Here, you can place components in your model simply by selecting them in the browser,

2:53 and then clicking in your model to place a component.

2:56 You can re-name the components or change the way your library is viewed.

3:01 Here, you can also explore beyond the components you have created.

3:07 The desktop version of SketchUp has a sampler library you can explore,

3:11 and both the desktop version and web version have a search bar where you can search the 3D Warehouse, which houses millions of user-created models.

3:24 You do need to be online for this search to work,

3:27 but the 3D Warehouse is an absolutely fantastic resource for finding SketchUp models that you can load directly into your model.

3:38 Because there are millions of models, it will help your search to be specific for the types of models you are looking for.

3:46 Also be aware that the quality of models can vary greatly, from simple, to very highly detailed models.

3:56 Finding really detailed components can help make your scene look great, but, be careful as well.

4:02 Loading a bunch of heavy models will quickly bloat your model size, and will impact the performance of SketchUp as well.

4:13 If you’d like to manage the components in your scene, click on the home tab in the component browser to view all the components you have created or added to the model.

4:24 To delete one, you can right-click on any component in the browser, and delete it.

4:29 This will also delete any instances of that component.

4:34 You can also right-click on a component, choose to ’Select Instances’, which picks all loaded copies in your scene...

4:43 ...and then swap those components for another by right-clicking on a different component and choosing ‘Replace Selected’.

4:51 It can also be useful at times to purge the browser, which will remove any component that is not currently loaded in your scene.

5:08 Let’s talk about component nesting.

5:12 We introduced nesting when talking about groups.

5:16 It's the idea that you can take multiple groups or components, and combine them into a larger group or component.

5:24 For example, if you open the component nesting file, we have this table and chairs, and they are already components.

5:32 I could select them all and group them to make it easy to move around as a single object,

5:39 This is a simple use of nesting, but we can also be strategic in how we nest objects, to make our models more efficient.

5:49 If I double-click to edit down through the nesting levels, I can open the large group that we just created and move around the chair components.

5:59 Then edit one of the chair components, which is also made up of a series of components,

6:05 so we could delete one of the back slats for all the chairs at once.

6:11 The back slats are also components, so we could edit one of those to effect the actual geometry and perhaps make them all thinner with push/pull.

6:23 At this point, we are 3 levels deep into a nested group or component, so we’d need to click outside 3 times to close that many levels.

6:36 In this example we have a mix of groups and components nested together but there isn’t one nesting strategy that works best for everyone.

6:47 Some SketchUp experts prefer to use and nest components only, and others use a varied mix of components and groups together.

6:56 You might use different strategies for different models.

7:00 We’ll explore more of those nested strategies in a later course, after we learn more about the move tool, arrays and the scale tool,

7:10 but we did want to introduce the idea of nesting so you can try it out on your own.

7:17 There are 2 other topics that we are going to delay for a later course as well.

7:24 One is creating face-me components.

7:28 In this office example you can see that as I orbit around, the people automatically orbit as well to try and face the camera.

7:39 These are called face-me components, and there are some special considerations when creating them.

7:47 The other type of component is a cutting component, often used as windows.

7:53 You can see that we have some here, which seem to be cutting an opening through this wall, but in fact if I erase one, the wall is healed,

8:03 and if I copy one, it will automatically align to any surface I want to place it on.

8:10 Creating this type of component must be done in a very specific way, so we’ll cover that as well, in a later course.
