Summary:
Design Technologist and Enscape power user Dan Stine explores the latest updates for SketchUp in Enscape 4.13, including SketchUp 2026 compatibility and the Save as External Model feature. Users can now manage large projects more efficiently by keeping models lightweight and responsive while maintaining visual quality.
Enscape 4.13 arrives with two updates that SketchUp users have been requesting. First, compatibility with SketchUp 2026 means you can move your studio forward without workarounds. Second—and the headline for many—Save as External Model is back in SketchUp. The feature converts components into Linked Models, lightweight stand-ins inside SketchUp that render at full fidelity in Enscape. In practice, it facilitates responsive orbiting, selecting, and editing even when a scene is full of detailed furniture, planting, or context models.

Enscape Linked Model workflow returns
If you’ve never used Enscape’s Linked Models feature, think of them as a clean division between authoring and visualization, which collectively can tax system resources. You still place and transform a component in SketchUp like any other object; you just store its heavy geometry in a separate .skp file. SketchUp stays nimble. Enscape pulls the detail at render time. It’s a simple idea, but on large interiors and campus-scale sites, the effect is immediate: the model is easier to drive, file sizes stay manageable, and teams can split scope to some degree—FF&E, landscape, or façade assemblies—into discrete, versionable files.
The feature was previously removed as the team worked through technical limitations; it’s now back in 4.13, improved, and aligned with Trimble’s current SketchUp architecture, following close collaboration with Trimble and strong community demand. That collaboration shows up in small but meaningful ways. Linked objects reload instantly when a teammate edits the external file. Instances remain instances, so edits propagate predictably. And because the link lives with the component, everyday SketchUp workflows—copying, rotating, swapping—continue to work the way you expect.
Try it out in the Apartment sample SketchUp model, the same one used in this article, which can be found on the Free Sample Projects section on the Chaos website.

Where it helps most is anywhere you were compromising either detail or interactivity. Asset-driven interiors are a perfect example. A library of sofas, casework, and lighting can live as external models on your server. The master file remains lean while you iterate through layouts and materials; when assets are edited, the master file and Enscape are updated instantly. Urban context is another good use case. Surrounding buildings, streetscapes, and dense planting can live outside the file so the design model stays focused on the parts you’re actively shaping.
This is not a step-by-step tutorial, but there are two UI touchpoints worth highlighting for your screenshots. First, the context menu for a selected component now includes Save as External Model for Enscape—a one-click handoff that writes the geometry to disk and replaces the in-model instances with proxies. Second, you can re-path to a different linked model through Enscape Objects → Linked Models. Those two pieces together form a small, clear mental model: author components are handled as usual, externalized when they become heavy, and then managed like any other reference.

Manage linked models via Enscape Objects dialog
Because Linked Models are purpose-built proxies, what you see in the SketchUp viewport is intentionally lightweight—a simple wireframe box that matches the extents of the linked model. The precision comes from the live Enscape window, where each proxy resolves to the full object with materials, lighting, and all the small features that sell scale. That split aligns with the broader Enscape philosophy that many of us rely on day-to-day: keep the authoring tool familiar and fast; let the renderer do the heavy lifting at display time. It’s the same mindset that makes Enscape’s material enhancements and export options feel like natural extensions of SketchUp rather than bolt-ons, which is one of the reasons why the workflow resonates with interior designers and architects alike.

A couple of practical notes from production work. Store external models on a path your whole team can access. Treat Linked Models like a small, curated library: name them clearly, keep materials tidy, and consider version folders for milestones. If you rely on batch rendering or panorama tours, Linked Models play nicely there too; Enscape resolves them at export, so you get the same quality you see live.

SketchUp 2026 support
Many firms hold back upgrades until their critical add-ins are ready; Enscape 4.13 now supports SketchUp 2026. Why update now? Because the combination of SketchUp 2026 support and Linked Models directly addresses the three pain points I hear about most: viewport performance on large projects, team organization as models scale, and the desire to keep visualization fully integrated while designing. With 4.13, you don’t have to choose between a responsive SketchUp scene and richly detailed renders in Enscape. You get both.
Conclusion
Enscape 4.13 gives SketchUp users precisely what they’ve been waiting for: the freedom to move to SketchUp 2026 and a smarter way to keep big scenes manageable. Save as External Model turns heavy components into Linked Models—lightweight in SketchUp, full fidelity in Enscape—so orbiting, copying, and everyday edits stay quick while your visuals never compromise. The payoff is both immediate and cumulative: faster interaction today and cleaner organization as the project grows.
If you’re already working in SketchUp, the next step is simple: update to Enscape 4.13, convert one hefty component to an external model, and feel the difference as you iterate. Then expand the approach to FF&E sets and site context. Your main file stays nimble, your team can version assets in parallel, and your real-time Enscape output—from stills and videos to panoramas and VR—keeps pace with design. In short, you don’t have to choose between a responsive SketchUp model and richly detailed renders anymore—you get both.
