Pressure Network Catalog Regen

[Cadguru42]

I have a pressure network where I drew some pipes in, but realized that the wall thickness was incorrect. I edited the catalog to fix it, but my drawing is not updating the pipes. New pipes that are created are correct, but the older pipes still have the incorrect wall thickness. Is there a way to force the pipes to regen based on the catalog or am I stuck having to redraw every pipe?

I believe you are stuck for 2016.

Looks like you have to have 2017, enhancement 1, to swap them out: http://up.autodesk.com/2017/CIV3D/AutoCAD_Civil_3D_2017_v1_enu.htm
