The exploded vertices in the bottom image look like what’s left if you delete all the polygons,.
but,. there’s another smaller version of the model at the bottom
Could it be that you’ve deleted an object at one scale,. pasted it in again, and scaled it down.
More info would help.
What was the model made in ?
What format is it,.
do you have a previous scene or version of the model?
If you open that, does it appear the same way.
What version of Carrara are you using,..
What Platform and OS ?
