I have a sheet metal part.
It was modeled with surface faces, converted into a sheet metal part, and features such as holes and cuts added to it.
Its growing exponentially. It averages 127mb, but sometimes grows to 250mb and higher.
I have done the following
-Unchecked link display states with configurations
-Deleted all display states
-Used "Mark and Purge data for all configurations"
-Unchecked "Save tessellation data with part document"
-Save-as a new part name
Looking inside the file structure, I can see where its inflated

So through a process of deleting items and saving the part, I've narrowed down the cause.
A series of cut extrudes after the sheet metal conversion (elongated holes/slots)
Drilled holes and other cuts are working fine without inflating the file.
What about this feature is causing the file size to double every other time I save it?
