I have created these surfaces and want to pull the profile line off the very bottom to see if it is fair. I can get most of it from isocurves, but I cannot get the bottom of the curved surface right. Is there any way to get that very bottom line.

I’d use Silhouette then immediately zoom in and deselect the segments along this line. Delete the rest of the silhouette curves after that. Join the curves left that you need and then use Make2D using the active Cplane. Lastly, one more Join and I think you have the curve you’re after.
Thats perfect, thank you. I didnt know that command existed.
