1. Select Ref. Geometry >> Create >> Cylinder >> Pick Boundary Points from the menu or click the icon from the reference toolbar.

2. Select more than 5 points that approximate where the reference cylinder should lie on the polygon model.

During picking points,  User can select point entity on RMB menu as below fig.

 

Point : Any point on polygon face

Vertex : Polygonal edge

Ref.Point : User made Ref.Point 

Point On Surface : any point on NURBS surface
