What am I doing wrong?! (STL Export)

[Coombed]

Hi all,

I have drawn 4 very simple objects in VW and I have exported to STL (Highest number of polygons). No matter what I do, despite exporting as described, the object (which should be a cylinder) is like a 16 sided circle.

If I draw a sphere on the 3d tools that exports fine, which is strange!

Would someone mind having a look at the file(s) and advise where I've gone wrong?

Thanks

Inside this extrude there are actually 6 objects, the 4 polylines that make up the rings and then it looks like 2 Lines. If I remove the lines from the extrude (which wouldn't be solid objects so STL export wouldn't handle them well) and then export to STL again, they export both at the correct size and without that severe faceting.
