I’ve saved some components in a folder in Windows Explorer using Sketchup 2017 on Windows 10. When I click on the ‘Details’ arrow icon in the Components tab of the Default Tray, and then “open or create a local collection”, it opens the correct folder in Windows Explorer, but the files aren’t visible.
I found a workaround: I used File>Import which opens the folder, but at first also didn’t show the files. The file type box had 3DS Files there as a default. I clicked the drop down arrow and chose Sketchup Files, and the files appeared. They are still not showing up through the component browser even though it opens the exact same file path.
The workaround solves the problem of not being able to get my components into a model, but I posted anyway in case someone has the same issue, and I am still curious why they’re not visible through the browser.
