Delete parts from model, for size reduce

SketchUp

i deleted so many details and groups from main model. at first model size was 132 mb, after delete i check file and it is same size again. why?

Did you purge unused components and materials from the file? If not, the file size won’t change. Window>Model Info>Statistics>Purge Unused.

Yes ofcourse i did, that why i asked. It is so strange size is not changing. I deleted 40 000 faces

You didn’t indicate that in your first post.

Maybe you didn’t purge enough stuff to get a significant change of file size. We can only guess since you haven’t shared the file with us.
