Assuming like most cad software your software stores an object internally as a circle (or cylinder/cone/sphere) but when you export to STL there should be options to control how much precision you want for your circles and all surfaces. At that moment your circles are likely getting chopped up into multiple segments.
As gr5 said, search for the STL-export settings in your CAD-program.
In DesignSpark Mechanical you have the options course, medium, fine, and custom. Fine is a good balance between file-size and smoothness, although the triangles are still visible in balls. Course and medium are too rough to my taste.
For really smooth surfaces, a custom setting is required. But be aware that a finer setting (=more triangles and thus a smoother curve) can soon make the file-sizes really huge and unmanageble. Instead of 2Mbyte it may easily jump up to 20Mbyte. And this might create other issues: the slicer slowing down, printer slowing down, wasting 95% of hard disk space for little improvements,...
So I would suggest that you experiment with all settings to compare the results, and then go for a good balance between quality and file size.
In this stable release, Cura 5.3 achieves yet another huge leap forward in 3D printing thanks to material interlocking! As well as introducing an expanded recommended print settings menu and lots of print quality improvements. Not to mention, a whole bunch of new printer profiles for non-UltiMaker printers!
The UltiMaker S7 is built on the success of the UltiMaker S5 and its design decisions were heavily based on feedback from customers.
So what’s new?
The obvious change is the S7’s height. It now includes an integrated Air Manager. This filters the exhaust air of every print and also improves build temperature stability. To further enclose the build chamber the S7 only has one magnetically latched door.
The build stack has also been completely redesigned. A PEI-coated flexible steel build plate makes a big difference to productivity. Not only do you not need tools to pop a printed part off. But we also don’t recommend using or adhesion structures for UltiMaker materials (except PC, because...it’s PC). Along with that, 4 pins and 25 magnets make it easy to replace the flex plate perfectly – even with one hand.
The re-engineered print head has an inductive sensor which reduces noise when probing the build plate. This effectively makes it much harder to not achieve a perfect first layer, improving overall print success. We also reversed the front fan direction (fewer plastic hairs, less maintenance), made the print core door magnets stronger, and add a sensor that helps avoid flooding.
The UltiMaker S7 also includes quality of life improvements:
Reliable bed tilt compensation (no more thumbscrews) 2.4 and 5 GHz Wi-Fi A 1080p camera (mounted higher for a better view) Compatibility with 280+ Marketplace materials Compatibility with S5 project files (no reslicing needed) And a whole lot more
Curious to see the S7 in action?
We’re hosting a free tech demo on February 7.
It will be live and you can ask any questions to our CTO, Miguel Calvo.

Are you a fan of tree support, but dislike the removal process and the amount of filament it uses? Then we would like to invite you to try this special release of UltiMaker Cura. Brought to you by our special community contributor @thomasrahm
We generated a special version of Cura 5.2 called 5.3.0 Alpha + Xmas. The only changes we introduced compared to UltiMaker Cura 5.2.1 are those which are needed for the new supports. So keep in mind, this is not a sneak peek for Cura 5.3 (there are some really cool new features coming up) but a spotlight release highlighting this new version of tree supports.

This is a cad setting.
STL files contain only triangles.
