Hi Michael,

>> Those particular curves don't seem to be in your previous model file, can you post them?

They were there, maybe one was missing. Here I attached a new file. In this file I copied and pasted the exact same curves and the resulting lofted geo seems cleaner strangely! I then filleted the top area and it gave creases again but I did undo and retried fillet and it seems to be cleaner? I am using Ver.4 Beta Feb-27-2019.
