Working in SketchUp feels intuitive—especially when you're importing ready-made components from the 3D Warehouse. But if you don’t pay attention to what you're loading, your file size can easily balloon to 100MB, 200MB, or even over 400MB for detailed architectural models.
Large file sizes come with long save and load times, especially on older computers. In some cases, the model might refuse to open altogether—even on powerful machines. If you've ever faced this frustrating SketchUp slowdown, here's a simple trick to keep your files opening quickly and safely.
💡 How to Open Large SketchUp Files Without Crashing
The trick is simple: switch to Wireframe mode before saving your model. You can do this by going to: View → Face Style → Wireframe
This trick also works well when you need to copy-paste (Paste in Place), move, or rotate large components. When saved in Wireframe mode, the file becomes easier for SketchUp to open later—even on slower PCs or laptops.
Why This Trick Works
Saving your model in Wireframe mode is typically 2 to 3 times faster than saving in Shaded with Textures mode. Next time you open the same file, SketchUp won’t have to load all those high-poly details or large textures immediately—giving you a smoother, faster experience.
Even on SSD-powered machines, this method improves loading time. More importantly, it ensures your file can be opened on another user’s setup—whether they have a slow PC, 32-bit SketchUp, or a low-spec laptop.
