Hi beanworks, can you please post the 3DM model file when you have a question about a problem with a particular shape like this? That makes it a lot easier to dig into it and see what's going on, it's much harder to diagnose geometry issues just looking at one screenshot where you can't zoom in and rotate around, etc...

Is it possible that your surface was created from a curve that was made up of multiple segments instead of only one single smooth segment? If so that could make that kind of result, the segmentation is basically transferred into the surface that's created from such a curve. Usually in a case like that you can fix that up by running the Rebuild command on the curve before using it for construction:

That tends to be the easiest way to convert a curve made up of multiple segmented pieces into just one single smooth segment.
