Tesselation
In order to display an object efficiently its surface is tesselated, i.e. it is displayed with some small deviations from it real surface. This applies not only to PartDesign models, but also to other objects in FreeCAD.

There is a lower limit for the tesselation of 0.01%. If you really want to spend the additional time you can reduce the lower limit even further by opening the menu This opens the parameter editor where you navigate to.

Right click on Mesh deviation choose in the context menu Change value. Set the value to the minimum tesselation of your choice. Please keep in mind that the value is in %, i.e. for a value of 0.005% you have to enter "0.00005". The smallest value possible is 1e-7. Note: In the preferences menu you will still see 0.01% even if you set a lower value.
