[Weird shape deformations in Cura]

Hi All, 

Im Erik and im new here.. 

Over the last couple of days I think I have run into a strange problem with (what I believe has to do with Cura) induced deformations of shapes. Are more people experiencing this? In the image below, the left two parts are fusion 360 design and section, to the right two of the results. In Cura though, the object seems identical to the fusion design.

Any info or help as to whats causing this greatly appeciated!

Thanks

Erik
