I exported a storm network from Civil 3D to Storm Sewers. After analyzing the network, I changed the names of a few storm inlets in Storm Sewers. When I export it back in to Civil 3D, it keeps the inlet with the old name and adds the inlet with the new name, but rotated right on top of the old inlet. I've renamed inlets in Storm Sewers before, and have not had this issue when exporting back into Civil 3D.
Any guesses as to what may be the cause of this ?
