I researched other threads and saw the recommendation to save the 3dpolyline as a 2010 dwg and import that. It now shows up on screen and appears to be showing staking data.
Never know what I was looking for until I was there looking!! I'll test it tomorrow. Its a force sewer main project that I grab as built info on as they go but they also want a quick and dirty check of the hole, hence the need for the alignment.
Thanks Shawn,
