Ah sweet thank you!

I figured that you can also just copy everything and then paste into a new document but it's good to know how to actually solve the problem properly

& sorry for the f***'s I was just pretty annoyed when I initially started the thread

Hi there,

I need Heeeeelp please!
Got a massive problem with sketchup and I have no idea how to fix it.

Everything is just fine but at some Point Sketchup randomly destroys my files in a way that I can't use them anymore. This is extremely annoying and almost made me smash my PC the other day because one of my files that I've been working on all night suddenly just became useless (angry smiley!)

It now just happened again and I really need to know whats wrong!
I attached a screenshot guess the problem is quite obvious.

A minute ago everthing was just fine and then suddenly "this" happens...

If you know a solution pls let me know asap I really need to get my project finished

Thanks!
