Model showing grey, all work unable to be seen, please help!

Hi there, I’m freaking out a bit as all the entities in my model cannot be seen or edited and the screen is grey. I have tried everything mentioned in the forums - from view extending, unhiding, copying into new file, but no luck. I have been working on this for weeks and it is due soon, any help would be much appreciated!

hi. you need to allow access to the link on google drive.

Ah sorry,

this should work

Open Outliner and delete the last group in the list then use Zoom Extents.
You are also using Tags incorrectly, do not change the active tag and do not tag raw geometry, only tag groups, components, dimensions etc

this worked thank you!

And thanks for the tags tip, will do in future
