I was adding some chamfers to an object in a file less than 500mb. After 10 or 12 chamfers, the file was still under 500mb. I added a few more (identical in nature to the others) then noticed the file had balooned to 3,131mb and slowed to a crawl. I checked for duplicates and none found. I exited and saved - the file shows as 3,131mb in Explorer. I reopened and Saved Small and the file went down to 3,060mb.
This is crazy… Any thoughts?
