Linked models serve as proxy objects that can be used in a very convenient way to add detail to your projects without making the model too heavy. Components within a model can be saved externally as individual *.skp model files and be imported into Enscape as a Linked Model. The linked model serves as a Proxy Object in SketchUp and it will show up as a wireframe box placeholder. It is quite similar to how Enscape Assets function. You can see the Linked Model as a real-time render in the Enscape Viewport. 

To import proxy objects, click on Objects in the Enscape Toolbar. Select the Linked Model option. You will be asked to locate the *.skp Model. Once selected, it will show up as a proxy object in your SketchUp window and as a render in your Enscape Viewport. 

You can create proxy objects using SketchUp components. You can either create your own components or use existing ones. Export components by right clicking and selecting save as.  Save the component as an external *.skp File. You can link this file as a Linked model inside Enscape objects window.

Updates to a Linked Model can simply be made in the external *.skp file. Open the file in Sketchup, update the model and save the changes. Once saved, changes will automatically update in your Linked Model file. 

In a case where the original location of a linked model has been changed, the model can be re-linked by selecting the placeholder inside your project. Once selected, open Enscape objects window. You will see a folder icon at the bottom of the window with your selected linked model name. Clicking on the folder icon will allow you to re-link the model path to the new location.
