I have an imported part from a 3D scanner that has hand sanding on it so there are some imperfections I want to fix and there isn't a straight surface to work from. Can't use feature recognition either. Most of the part looks like this, many facets and no real radii. Is there a way to "pull" material up? I have tried move surface and haven't been successful. Maybe knit a surface around the opening and somehow fill it in? The hatched area is the are I want to fill in.
