Taz 6 issues with flat curves

I have a Taz 6 that I’m slowly working thru some issues with. The question I have now is regarding curves. Instead of prints having smooth curves, they are choppy flats, like poor resolution. What do you think could be causing this?

I don’t want to assume, but I know the print bed bushings seem to have a lot of slop in them. I just replaced the tool head bushings and it feels great now. Or should I look at something else?

The material used is PLA with an aerostruder and Cura 4.13.17

That looks 100% like it’s the actual geometry of the file, not an issue with the printer.

Post the STL and it’ll be easier to check.

OMG, you’re 100% correct, it was the file. The .stl was output from Catia and it’s settings are based on Catia’s display setting. Thank you again for digging me out of another issue.
