My future ground somehow disappeared out of one section view in my group. Under the section tabs I still have my existing ground and pipenetwork but the future ground isn't there. It remains in the other section views. How do I add it back?
Right-click that section view and go Update Section View... Or you may have removed your FG from the sample line. Go to sample more sources and ensure it's sampled. I generally try to tweak everything within the Section View Group Properties that way everything stays the same. Good Luck.
