I have been working on a small project, as yet unfinished - and when I saved the job, I received a message 'No Error Found'
I then tried to 'save as' a different file name - same message appeared.
Numerous attempts to save ended with the same result,
When next I opened sketchup, I tried to re-load the file and now recieve a 'Unexpected File Format' message.
The file I want to load shows up in Windows Explorer (thumbnail mode) with a small thumbnail OK and a file size of 1216 kB.
I even re-named the .skb file and tried to load that, with no luck what so ever.
Anyone have any ideas or suggestions on how I can recover this
Previously created projects (different jobs) all open okay, as a test of Sketchup itself.

When you want to use SketchUp with other modeling programs or tools, that typically means you need to either

  • Import a file from another program into SketchUp.
  • Export your SketchUp model into a file format that works with another program.
Tip: When this article refers to other modeling programs or tools, that means programs outside the SketchUp family of software and tools. If you want to open a 3D model as a document in LayOut, create your own styles in Style Builder, or share models on SketchUp Mobile Viewer or the 3D Warehouse, these programs and tools are designed to work directly with SketchUp. Each of the these applications has its own section in the Knowledge Center, which can help you get up to speed quickly and easily.

Here, you find subarticles about working with CAD files, different types of image files, and other file formats designed for sharing 3D modeling data between applications. To import or export some of these files, you need a SketchUp Pro license or active SketchUp for Web, Shop Edition subscription. The following table has a full list of the different types of files you can import into and export from SketchUp.

Note: The SketchUp Subscriptions have additional import and export options as well.
