This will be two part.
1. How do I add elliptical pipes as a "min to max" option for the design feature? I know I can input width and height but it sure would be convenient to have the design function incorporate elliptical pipes.
2. I have read and tried a few things within the "edit pipe network (feature settings)" to get my storm sewer file to import back into my civil3d (2016 by the way) and I just get the error "error accessing the parts list". I am ok with the pipes not coming in correct per part list but I would like if my edits made to the inverts would import in and I can swap my pipes for the correct elliptical pipes (which I do have in my parts lists).
Thank you and have a nice day,
Brandyn
