Hello,
I am working on design sewerage system for a zone, about 22 km of networks are collected with one station.
when i choose the design engine it the file gives me error that the invert level is higher that the ground level.note : the ground elevations are mostly in negative.
so i tried to change the invert levels to -20 m but it didnt work as well because it kept the slope as min and contained desgin using -20 m level.
another issue is conduit catalog should contain conduits that available for design.
thank you
