DRAFT Single line Extraction problem

Make sure your piping component primitives in Paragon have both Centerline and Tube flag ON

 

Thank you for your reply Corrado,

I have checked it for almost all component Primitive both Centerline and Tube flag is ON,

but still m not getting it...:(

Check the sequencies of your RRUL elements.
The RRUL for components must be higher then the RRUL for PIPEs
