yep that's what it was! thank you! I was surprised I couldn't use a profile that had spiralize and then turn that off for the model I'm working on. Now I know!
I printed some vase type things a few weeks ago for the first time and now cura 3.6 seems to ignore that I have turned off smooth spiralized contours and surface mode to normal or both. when I import a design it shows up with no top or infill unless I set the infill to 100% then it looks solid. thanks for any adice you can provide!
