Can I create a Cylinder or Diameter from lines?

[[Is...]]

I'm doing tests to see the difference between Zeiss Inspect and Calypso calculations, so I'm wondering if I can replicate such Calypso evaluation methods like lines on the cylinder, or several circle sections.

For example, I created the cylinder lines from two perpendicular, longitudinal sections, and then I created the circle sections with multisection. 

From the circles I can calculate diameter, but I don't know how to take the combined arithmetic mean of all of them, or create a cylinder from them. 

Also, I don't know how to extract a diameter or cylinder form the created lines.

Is this possible at all? Or is it recommended to stay with the simple cylinder creation - diameter check?

I was able to compare ATOS 5 vs Accura on same part using curves.

I've exported nominal points from curve into csv and then imported into Inspect. Then i did intersection with mesh and from those points i did discreet cloud point.

Then i did surface profile and instead of mesh i've selected this cloud - result differed 0,01mm on profile ( doubled worst devaiation - so 0,005mm ).

I also tried to make 1:1 base alignment - so i was pretty satisfied with result ( having in mind part is sand blasted and was not used any spray ).
