I created multiple pipe networks for a proposed site, and each structure pulled the rim off the proposed surface.
We had some issues, and now the surface elevations have changed. Is there a way to get my pipe network to automatically update the rims? I can't seem to figure out a way.
Make sure the structure has the surface assigned to it and that the surface rim update value is set to true. If you are using 2007 there is a utility that will update the rims for a network provided by Matt Kolberg.
