Embedded Files
Groups
Groups
Modelers need to have a way to control how things interact. Grouping stuff is a quick way to segregate related entities from the rest of the model. Things inside the group or component wrapper will not be affected by changes on other parts of the model.
To get more control over a wrapper itself and the contents of the wrapper, jump into the use of components. TaffGoch created a HousePlan file to help people understand how groups and components are used. Open the Entity Info window while examining the file - from the Window menu, SketchUp menu on a Mac. Entity info lists what the parts are and layer location.
Components
Components
Like groups, components throw a segregation wrapper over selected entities. But it does more.
If you are using the same entity multiple times (for example, a window or a tree), make it a component, and then use copies of the component. Multiple instances of a component are lighter-weight than multiple copies of an entity or group.
Use components as an archive.
Save a copy of a model in Component Libraries/Collections to readily retrieve it for future use.
Use the component as a jumping point for future model modifications, as there is a tool in the context menu (select component, right-click) to make a unique copy.
When a part of the model is in an awkward location to modify in situ, add a copy of the component in an accessible location, square to axes, to modify the geometry instead.

How to set-up custom component collections
Bring the components into the main, master model file by importing them through File > Import or through the Components browser from a custom, component library.
Refresh those edited library components as changes to external SKP files and library components do not automatically update when changes are made in external copies.
Context menu
Select a component in the model workspace.
Right-click and choose Save As in the context menu to save the component to an external location.
To update the external component, select the component, right-click > Reload.
Component Browser
Click on the house icon to get the In Model components.
Right-click the old component and select Reload.
Component context menu options
Components Browser
There's a Xref Manager plugin for those accustomed to AutoCAD methodology. Xreffing is a way to coordinate and manage the re-importation of external components and DWG/DXF files into the master SKP file. Look for the latest version of XrefManger. Open the plug-in in a plain text editor, like Notepad, to find additional instructions.
BIG TIP: Do not change components axes on a Saved As component...
If you set up a component in a master file and want to save it in a separate file, do not disturb the axis location in the new file.
The axis acts as a registration point. When the external model is reloaded into the master model, it will be oriented and placed according to the axis position.
For example, layout and set up a component in the master file. Then select the component and save it in an external file. Stop all new modeling of that part in the master file. Instead refine and update that model in the new, external file. Do not change how the model is oriented to the axis. Whenever changes need to be shown in the master file, select the affected component and Reload it from its external location.
Proxy Components
Proxy Components
Use low-poly, proxy components as place-keepers
Try using low-poly component versions early in the modeling process. Replace them later with better components.
Make a replacement component. It will appear in the Components browser, In Model library (click on the house icon.)
Select the component you want to replace in the model workspace.
Right-click on the replacement component in the Components browser and select "Replace Selected."
Use low-poly components for distance view Scenes of the model. Then only use more detailed component versions for close-up Scene views. (See the Relevant Plugins section below to help automate this process.)
Add separate Layers for the high-poly components and low-poly components.
Place the high-poly component on it's own Layer and its low-poly counterpart on another Layer.
Place a low-poly component and it's higher-poly counterpart on top of each other.
Make some Scenes with the low-poly Layer visible and make some final presentation Scenes with the higher poly Layer visible.
One technique if using a proxy-making plugin. This method will not reduce file size, but switching visibility between high-poly components and the proxies is 'quick'.
Add separate Layers for the high-poly components and low-poly components.
Place the high-poly component on its own Layer.
Copy high-poly component (Edit > Copy or Ctrl+C in Windows).
Paste the copy on top of the original (Edit > Paste In Place).
With the copy selected, move the pasted copy onto the proxy Layer
With the copy still selected, r-click and select Make Unique from the context menu.
Change the new, unique component into its proxy version with the plugin.
Set up Scenes as needed with high-poly and low-poly proxy Layers visible.
Keep low-poly components as place-keepers in the original file and work out the component details in a different file.
R-click on a component in the original file and choose Save As from the context menu, or r-click on the component from the Components browser. Either way will create a new SKP file from the selected component.
Bring back the exiled component by either r-clicking on the original component in the workspace or from the Component browser and choose Reload. The component axis acts as a registration point for the reloaded component.
Check out the proxy plugins listed below.
Note:
Some ray tracing renderers can be set up to ignore the low-poly, proxy models which are visible in the workspace and will render the high-poly models placed on invisible layers instead. Check with your renderer for this option. For example, the renderer Shaderlight includes a proxy tool called Replace Me.
Tips from the developer of 3D TreeMaker, Pascal Poublan, who included a proxy-making tool in the extension. While the advice is directed on optimizing the use of the extension, it is good advice on helping other large, balky models too.
Yes as the plugin is creating lots of geometry it can become slow and difficult to work with the SketchUp model.
Here are some tips to speed up the use of TreeMaker within SketchUp.
Close the SketchUp Outliner Window.
While working with your model, disable style view features that are taking long to draw.
Shadows
Fog
Edge profiles, depth cue and extensions
Create your trees in a new empty model
When you want to test and make many changes to one tree configuration, do it on a new empty SketchUp model.
When you’r happy with the result, convert it to proxy with the integrated tree maker proxy function
Then copy/paste this component (which is small) to the final model where you can make instances
Use TreeMaker proxies features within SketchUp.
Switch all trees to proxies when you work on other parts than trees in your model, or when you just place or move existing trees. You can do this from the tool button or menu “change all trees to proxies”.
Save the model while trees are in proxy mode. File will be of a smaller size and will be saved and loaded faster.
Redraw all the trees (with the button or the menu) only just before rendering your final image or exporting 2D image
Put trees in a different layer.
Put all the trees on one SketchUp layer.
When you want all the trees to be redrawn : disable the tree layer, redraw all trees, and enable the tree layer.
Disable plugins that are looking for geometry changes in real time in SketchUp when you want to build trees.
This is the most difficult part to explain as there is no way to know in advance which plugins. This is the case for BGSketchup_Composants, Eneroth Railroad, and renders that are updating geometry in real-time with integrated SketchUp viewport.
