Do you've SOLIDWORKS Premium? If yes then use surface flatten.
i do have but 2015 and its greyed out. but i managed to find someone with a 2016 premium who did it for me
you are right though
btw,.. interesting bug,.. anyone notice the Body-Delete does NOT show the selected "Bodies to delete"?
it's in 2015/2016/2017... you have to ctril-q (or delete/undelete) for it to re-appear.
Yes I do find that strange.
