Prusa slicer loosing holes on curved objects

Only on curved surfaces prusa slicer is loosing holes ( extruded, or "hole", any size )

Object is created with 1/4 eclipse which is 360 revolved on Z axis.

On flat or sphere objects holes don't disappear. 

 

STL file

Compressed .3mf file as suggested before

I created another small object with two  holes and  still have same problem with holes disappearing when slicing.

@astroxss

What program did you use?
I opened up the file in Fusion360. It appears the STL-file in your first post is not a solid, it is more like a tent.
One bottom surface with holes and a domed surface with holes.

It is hard to tell by my printscreen, but if you look down through the big hole in the dome you can see the small hole in the bottom, and that should not be possible if it is solid.

There is an example attached that I draw quickly in Fusion 360

SOLVED:

In fusion 360 used "boundry fill" tool. 

It still had problems when slicing ,but "Fix using netfabb" tool in slicer solved that.

 

Problem was that object was not solid + some manifold problems.
