This does not appear to be a Sketchup model! please help ASAP

Hello, my 10 hour project is broken, please help someone open my file, I have a spare save that won’t open either, im sorry file muss to archive
123.zip (18.3 KB)

Uncountably the file contains only zeros, there is no chance to recover it. :frowning:

Perhaps share the “spare save” and .skb file, to see it is better or not.

are u seriosly T.T

Yes, I am. You can see the original file size before zip-ed is about 18 MB, but the packed one is only 18 kB, this is indicating already a damage. I opened your file in hex viewer, and that showing only zeros. :frowning:
