Hello, I need help with opening the file I just made a couple hours ago. I saved it in my hard drive and when I try to open it again, it says that it doesn’t appear to be a SketchUp model. I already tried to open it from a blank page in sketchUp and other things. Can you help me please?

I’ll attach the file below

TEATRINO.skp (186.5 KB)

The file appears to be random data. It isn’t a SketchUp file, or any other kind of file I can think of.

How did you make that file?
