File too heavy

Anyone know how to make a revit file significantly lighter?

So far I purged unused items and saved it as a compressed file, but it’s still too large to turn in to the homework submission box…

From class 12 students usually email it to me directly. I will see if theres a way to change the size which can be uploaded

Ok, thank you!
This is for class 18 - so the same file as class 12 just heavier…

Is it okay if I email it?

Yes
